DIY wall plaster repair

In detail: DIY repair of a plaster wall from a real master for the site my.housecope.com.

Very often, a well-known and affordable method is used for finishing the facade - plastering. Despite the fact that expensive compositions or budgetary ones are used, repair work still needs to be carried out.

Plaster repair can be reduced to trivial staining if the dye in the solution was of poor quality and quickly faded under the influence of the sun. But sometimes it is necessary to make a more complex restoration - to repair cracks or exfoliated areas.

There is nothing complicated here, it is enough to purchase paint for the facade, which can be applied to the plaster in the required amount. If you plan to radically change the color, then calculate the quantities for 2 or even 3 layers. But when choosing, be careful and consider what kind of plaster was used to decorate the facade earlier.

The work process is as follows:

Cleaning the facade from dust and stains, if any.
Primer can be applied.
Wall covering with 1 coat of paint. To do this, you can use a wide brush, roller or spray gun. The latter option will significantly speed up restoration work, but such an apparatus will be difficult to find. Therefore, the best option would be to use a roller.
Once dry 1 layer can be applied 2.

It's a little more complicated here. To make repairs to plaster walls with your own hands, you will have to work longer.

First, you should purchase the same plaster that was used to decorate the facade. If a dry mix was used, it is not necessary to knead a large amount. Do as much as you can to deal with one bulky or a few small imperfections.
Secondly, you need to carefully examine the surface of the walls. This will help to assess the volume of repair work, and also to determine whether, in addition to cracks, there are also exfoliated areas. If such imperfections are present, then in that place the layer will swell. To check the suspicion, you need to knock with a rubber or wooden hammer, and the handle of a spatula will do. If there is a defect, a dull sound will be heard.
Third, the place of work should be well prepared. Cracks are cleaned of dust and dirt and treated with soil or soda solution.
While the treated area is drying, you can prepare a small amount of plastering solution.

After such preparatory work, you can begin to eliminate the shortcomings. If the layer was smooth, then there should not be any special problems in the process of repairing old plaster.

The crack is tightly filled with mortar.
The surplus is removed with a flat trowel and carefully rubbed to obtain a flat surface that does not protrude above the old layer.
Thus, all the disadvantages are handled.
After the solution has dried, the areas need to be properly sanded.
If the solution was gray, then on top of it you need to apply a thin layer of putty, then when staining, you will not have to apply the dye in several layers.
The last step in the partial renovation technology will be painting the facade. Professionals recommend, after repairing the plaster of the walls, to update the entire area in separate places. Thus, the decorative finish will look fresh, and after some time of use, the shade may change slightly. Therefore, when buying the same paint and the same color, the repaired area can stand out.

After the flaws were found during visual inspection and tapping, they must be removed.Plaster, which is crumbling or peeling from the base, is removed until there is a layer that adheres firmly to the wall. It is important not to miss a single piece, otherwise this method of repair work will bring bad results.

After a while, areas will appear again that spoil the appearance of the building. And this means you will need to repeat all over again. Therefore, you need to carefully inspect the facade and clearly follow certain instructions in order to properly repair the plaster.

After the old layer is removed, the area must be cleaned of dust. To do this, you can use a paint brush dampened with water or a medium pressure washer.
Dry the surface.
Treat the wall and elements of the old plaster that has remained with deep penetration soil. This is necessary so that the base does not absorb moisture from the plastering solution and to increase the adhesion of both the base and the old layer with a new composition.
Dry the surface.
Now you can start filling the desired areas with the solution. Everything is done in a standard way. The solution is taken up with a spatula and spread evenly over the surface. As in the previous version, it is imperative to ensure that the new surface is flat and does not protrude above the old layer.
After 30-60 minutes after applying a fresh layer of plaster, you need to wipe it thoroughly.
After the layer is completely dry, it is sanded and a perfectly flat surface is created.
The last stage of plaster repair will be staining. It is advisable to paint the entire facade in 2-3 layers.

In order to remove imperfections from structured plaster, and at the same time save the drawing, you will need to remember exactly how it was applied. To repair the "bark beetle" you will need to buy a specialized compound.

The preparatory stage and filling of cracks and other depressions is carried out according to the same scheme that was given above. But after the solution has set, it will be necessary to wipe it in such a way that a drawing is obtained that repeats the old one as much as possible.

If a special roller was selected to create a pattern on raw plaster, then everything should turn out quickly and easily. The main thing is to take the same tool and place it correctly so that the drawings clearly coincide. It is better to do this work in stages if there are several places with imperfections on the facade.

First, fill one area with a solution, wait for it to solidify and make a texture, and then move on to another. Otherwise, you can skip the moment when the solution lends itself to structuring.

It will be more difficult to deal with the texture, which was made with scrap materials. It will be difficult to repeat such a pattern. Therefore, before starting repair work, you need to practice on a separate surface or remember how the process was performed.Do-it-yourself repair of plaster on the walls in a living room in a private house: the wall is cracking inside or outside: Step-by-step instructions + Video Image - DIY plaster wall repair

Plastering is a proven and reliable way to level and protect walls, both outside and inside the home. Good plaster protects the house from the penetration of moisture, fungi, harmful microorganisms, ensures the preservation of heat in the house, and can also serve as a decorative element in the interior.

However, over time, any plaster in the house tends to collapse, after which it needs to be repaired. Despite its durability, even the highest quality material is exposed to external influences.

Cracks and chips appear on the plaster, especially near window or doorways.

Repair of plaster walls in separate places does not require much effort and is carried out using a fairly simple technology. But first, you need to prepare the walls for local repairs, this can be easily done with your own hands.

Cracks can be seen well, but it happens when the plaster lags behind the base of the wall and this can only be noticed by a slight swelling of the material. To identify a defect, it is necessary to tap on suspicious places with a spatula handle or a wooden mallet. The peeled plaster will break and crumble, the damaged area must be cleaned with a spatula.

The reason for the swelling of the plaster in some places may be traces of paint, grease or lime left on the wall..

They should be removed so that the new finish layer lies flat and subsequently does not repeat the fate of the old plaster. Grease or soot stains are removed with a 2% hydrochloric acid solution. Copper sulfate or a 3% hydrochloric acid solution helps with rust.

To repair wall plaster, we need:

To repair old plaster, you need to clean the seams by 5-10 mm, remove dust and dirt from them. Then they are thoroughly cleaned with a metal brush and treated with warm water so that the new layer of plaster adheres tightly to the old one. The area of the wet surface to be repaired is primed and a plaster solution is applied. At the same time, in rooms with high humidity, cement plaster is used, wooden surfaces are treated with limestone material.

Lime plaster is the most common material for interior wall decoration. The ready-made dry mix is prepared by hand after the treatment of damaged areas.

Advantages of lime plaster:

Ease of use;
The material has good air permeability;
Refractoriness;
When processing wooden walls, lime plaster protects against rodents and insects;
Does not collapse when hammering in nails.

Mortar Is a mixture of river sand and quicklime in various proportions.

Mix preparation method:

Lime is poured into an enamel or metal container.
Fill completely with warm water and cover with a lid.
After the lime has stopped sizzling, the mixture must be filtered through cheesecloth.
Add the sifted sand to a container with soft lime, you can add a little water and mix thoroughly.

Internal wall plaster repair technology consists of the following stages:

Water is sprayed over the surface to be treated.
A primer is applied to the layer to be repaired.
Plastering.
Finishing grout.

If the cause of peeling of the plaster is a fungus, which often occurs in damp rooms, it is necessary to eliminate the cause of the occurrence of harmful microorganisms. The damaged solution is removed, while a significant part of the unharmed surface should be captured. To prevent fungal spores from spreading to other surfaces during operation, the wall should be wetted. After the wall is dry, apply a fungicidal antifungal agent to the damaged area.

Facade plaster repairs may require additional work in the form of reinforcement. To repair cracks, a reinforcing tape is laid in them, and a mesh is glued onto a flat surface.

The plaster is applied in 2-3 layers, each layer is applied after the previous one has dried. Use the same plastering material as used previously to avoid cracking or chipping. The top can be clad with plasterboard or panels of any other material. If the surface will be pasted over with wallpaper, the new plaster should be filled and fine irregularities should be rubbed.

Wet rooms, such as baths, kitchens, and bathrooms are often tiled, but the plastering of the floor, walls and ceiling needs to be repaired first before tiling.

Decorating internal walls with decorative plaster is a simple process, as a result, we not only protect the walls, but also get a beautiful design of the walls. There are three types of decorative plaster: polymer, polymer-based; silicate and mineral-based, consisting of cement and lime.

For decorative qualities, plaster during apartment renovation is divided into:

Structural, grainy;
Textured, with its help a relief drawing is created;
Venetian plaster.

The problem with the renovation of decorative or Venetian plaster is that it is very difficult to achieve the identity of the renovated area with the rest of the wall surface in color or design.

Especially if you are doing the work yourself... Therefore, if repairs are inevitable and the wall defect is too noticeable, you should think about replacing the plaster all over the wall.

Features of plaster on different surfaces:

1. Plaster brick walls - to level the brick wall, a large amount of the mixture will be needed, therefore it would be more expedient to plaster in two layers the first with a cement-sand screed, after which to give the wall a more complete look, use gypsum plaster. It is not necessary to prime brick walls. With a thick layer of plaster (> 4-5 cm), it is necessary to use a metal reinforcing mesh.

2. Plastering concrete walls - it is best to use a gypsum mixture immediately, since the concrete slab has a smooth surface, and, therefore, poor adhesion. Before you start plastering such surfaces, they must be over-primed.

3. Plastering of foam concrete walls - any plaster is suitable for plastering this surface. The surface only needs to be primed.

4. Plastering of walls from tongue-and-groove plates - any plaster is suitable, but a gypsum mixture with preliminary priming of the surface is more acceptable.

This method is quite simple and the principle of its implementation consists in manually applying a cement-sand mortar to the wall surface with a trowel or spatula (this is more convenient for someone). To do this, take a grater in one hand, put a certain amount of mortar on it, and also throw it on the wall with a trowel or spatula. At the same time, when throwing the solution onto the wall, it is necessary with a characteristic slap - thus, the solution adheres better to the wall surface. By the way, it is better to moisten the surface of the wall with water before applying the plaster. After a certain section of the wall is filled with mortar, take a float and level the surface in a circular motion, if necessary, add the mortar with a trowel. If you plan to apply a thick layer of plaster more than 5 centimeters, the process must be divided into several stages. First, you need to install a reinforcing mesh, then apply one layer of plaster, and only after the first layer has dried, and after about 7 - 8 hours, you can apply the next layer, and so on. Do not try to speed up the process and do everything at once - the layer of plaster will fall off and you will have to redo everything from the beginning.

As we said above, gypsum plaster dries very quickly, therefore, with this method of leveling the walls, you will save a lot of time, about three times less than with cement-sand leveling the walls. The process of plastering walls with a gypsum mixture is as follows: the gypsum mortar is applied to the wall with a small spatula, after which it is leveled with a larger spatula along the plane of the wall. As well as when plastering walls, with a cement composition with a large layer thickness, it is necessary to take breaks of 1.5-2 hours between the application of the next layers.

The previous method of plastering walls is certainly quick, but the result without certain skills is far from excellent. Therefore, it is best to do the plastering of the walls with your own hands - along the lighthouses. The process of preparing the surface of the walls for plastering in this way will take longer, but the result will be incomparably better. A special metal guide profile is used as beacons; it differs slightly from those profiles that are used when installing a false ceiling with your own hands.

First of all, you will need to determine the geometry of your walls, this is necessary in order to form a flat surface.Using the building level, you need to determine the state of the wall surface along the vertical axis. By the way, if the level is small, this can be compensated for by the rule. Then we lay down the first lighthouse. To do this, you can use both dowel-nails and plaster mortar. Take a solution and make bumps every 25-30 centimeters, after which you put a beacon on them and use a level to control the curvature, and after the solution solidifies, the beacon will be reliably fixed. At the same time, control the thickness of the future plaster layer. The verticality of the beacons can also be checked using a plumb line.

Thus, at first, two lighthouses are laid in opposite sides of the wall with an indent from the attached walls by 20-25 centimeters. After that, between the beacons, pull the lace (above and below the wall) and, if necessary, install intermediate beacons, and the distance between the beacons should be slightly less than the length of the rule. It is better to fasten the lace with self-tapping screws set according to the level, otherwise, when pulling the laces, the beacons can be displaced, which cannot be done. After installing all the beacons, at least 12 hours must pass for the fixing solution to solidify properly.

The described method can attract certain difficulties for beginners in this business:

1. It is necessary to properly prepare the fixing solution (it should be slightly thicker than usual);

2. So that the beacons do not fall off due to the fact that the solution does not stick to the wall, it is necessary to moisten the wall with water;

3. Experience is needed to correctly place the beacons;

4. It takes time for the fixing solution to freeze, otherwise buy special plastic fasteners for fixing beacons.

If you plan to use these fasteners, then the process of plastering the walls along the beacons will be as follows: in the places where the beacons are installed, drill holes for the dowels. Next, install the mounts for the profile of the lighthouse and use the level and plumb line to control the verticality of the lighthouse, screwing in and out the screws if necessary. Similar to the previous method, fix two beacons along the edges of the wall, pull on the lace and install all the necessary intermediate beacons. This method will allow you to more accurately set beacons and significantly save time for work.

With all the preparatory work completed, which means that you can start applying the plaster mixture. The plaster mixture is thrown (it is thrown, so it adheres better to the wall surface) on the wall between the lighthouses, after which its excess is removed using the rule. The rule must be carried out from the bottom up, and in order for the solution to lay down more evenly, the rule must be periodically moved from side to side. With a large thickness of the plaster layer, the process must be divided into two stages: first, put on a layer of plaster and leave it in this position (with bumps) until it dries, then apply a second layer and level it as a rule.

It is relatively easy to do plastering of walls on lighthouses with your own hands, and on the other hand, it is quite profitable, because construction crews will take good money for this type of work.

As usual, we advise you to watch the video titled:

Plaster is not eternal. The owners of houses and apartments face a problem when it begins to crack or fall off in places. What to do? We will consider the reasons for this phenomenon, as well as how to repair the plaster of walls in separate places and the technology of surface restoration. Image - DIY plaster wall repair

Defects on the surface, causes and method of restoration
There are a number of defects that are formed when the proportions of the components of the composition are violated, or the technology of its application. The list is as follows:

Surface lumps and swelling.
Sedimentary cracks.
Fresh plaster is peeling off the wall.
Cracking along the entire depth of the solution.
Efflorescences, spots and stripes appear on the wall after the plaster layer has dried.

What is the cause of these defects? Swelling and bumps can appear if the limestone composition is unstable and has unqualified particles. How to repair lime plaster in this case? It is necessary to cure the plaster until the lime is completely extinguished. Defects are opened, abundantly moistened with water and filled with plaster mortar. It remains to wipe the surface.

Sedimentary cracks are formed with poor mixing of the composition and with an excess of binder. The exact proportions and dosage in accordance with the packaging will help to solve the problem. It remains to thoroughly mix the plaster and level the surface.

When the substrate has not been prepared, cleaned, rough, too dry and dusty, fresh plaster can flake off when sprinkled. To solve it, you will need to suspend work and start preparing the surface. The application technology is as follows: notches are made on the surface for better adhesion (or shingles are made), the wall is cleaned of dust and dirt. In addition, it is moistened with water. Then the mixture will not flake off, and the repair of plaster and surfaces inside the building will not be needed for a long time.

If the problem lies in cracks along the entire thickness of the plaster layer, then there is exactly one reason - there is no reinforcing mesh between the wall and the plaster. The base material is not rigid and is not reinforced in any way. The technology for applying the mixture is that the subsequent finishing layer should be less durable than the previous one, that is, there is less binder in its composition. So that the intermediate layers do not dry out, they need to be moistened with water and reinforced with a mesh.The last defect is spots and stripes. They most often appear on the outside of the walls. This could be due to a very damp or wet surface. Especially when the plaster is applied after rain. The solution is to process the dried walls, make waterproofing, so that moisture does not pull up from the ground. Local repair of plastered walls is done differently. The technology is simple, but requires careful consideration.Do-it-yourself repairs to a wall with pieces of plaster that have fallen out. The work is not difficult. You just need to follow the instructions. Alternatively, you can completely remove the layer and apply a new one. But it is more profitable to plaster the damaged areas. It all starts with an inspection. It is important to identify areas that need repairs. A wooden mallet is required. We'll have to lightly tap the wall. If a dull sound is heard, then the composition has departed.Then the sequence is as follows:

After the examination, the old plaster must be removed. We do not touch the places where it holds well.

Next, the seams are cleaned if it is brickwork. The surface is cleaned of debris and dust.

A primer is applied to the wall. It is needed for better grip.

After the surface has dried, the wall is slightly moistened and the solution is applied. If most of the wall has peeled off, then you will have to use beacons and a rule. Only in this way the wall surface will be perfectly flat.

For minor damage, plaster is removed in the form of a square or rectangle. The site is processed according to the method described earlier, and the cavity is filled with the prepared composition. It is important to stick to the proportions so that the mixture has the correct consistency.

Another restoration option is restoration with corks. In the right places, a hole is drilled to the base, primed, filled with mortar and plastered.

Note! For wooden walls, use a limestone mortar. However, it is not suitable for wet surfaces. Better to resort to a cement mixture. The corners are recommended to be treated with gypsum plaster, as it sets faster.Repairing plaster also involves removing stains from the surface of the wall.They appear during operation and can be from grease, soot or rust. It also happens that the spots were formed before finishing work. In this case, you will have to solve this problem before you start gluing wallpaper or laying tiles. The restoration work is as follows:

For greasy stains, use a 2% hydrochloric acid solution. The composition treats the entire surface with spots until they disappear.

As for rust stains, copper sulfate or a 2% hydrochloric acid solution will help to cope with it.

If the stains have strongly eaten into the plaster and cannot be cleaned, then you will need to seal the area with dye or whitewash.

Advice! Whatever surface you clean, it is important to first clean it of dirt and dust. Only after that other manipulations are performed.

The restoration of the surface under the tiles requires special attention. The procedure is as follows:

using a rubber mallet, the surface of the wall is tapped. This is the only way to determine a peeled or poorly fixed area;
when the site is found, you need to knock harder so that the tile falls off. If it is not removed in this way, then you will have to act radically - to break it. The process requires accuracy: the tile is broken from the center so that the adjacent one is not damaged;
if after removal a solid layer of plaster remains, then it is not necessary to knock it down. The new tiles should be glued more reliably using special glue;
when the plaster falls off, the place is cleaned, primed and plastered again. After drying, a new tile is glued.

Removing surface cracks is much easier. Repair of wall plaster in this case consists of two stages: surface preparation and plastering. To begin with, the cracked wall is cleaned of old cladding material and dirt. After that, a primer is applied to the surface. When it is dry, you can start stripping to give the wall a smooth finish.

Then the plaster is mixed and applied to the surface with a thin layer. The composition is leveled with a spatula. In the presence of large cracks, it is better to reinforce the structure with a reinforcing mesh. With it, the plaster layer will be much stronger and will not crack.

Peeling plaster is a small problem that can be solved by hand. No need to redo all the work. It is worth carrying out restoration work, which will take a maximum of one day, plaster mix, a primer and a trowel with a rule. Even with cosmetic repairs, it is recommended to remove the old solution so that it does not fall off along with the finish during operation. Stains and cracks also need to be repaired. Then you can be sure that the finish will last for many more years.

Sooner or later, the topic of renovation comes up in every home. The final appearance of the premises will also depend on the quality of the preparatory work carried out. Having applied once strength to a high-quality finish, in the future it will only be possible to periodically re-glue the wallpaper or change the color of the walls. Initially, it may seem that the work of a non-professional master cannot be done. But you can try to make at least rough sketches. In addition to moral satisfaction, this will also significantly save your personal budget. This review describes in detail the entire technological process of how to plaster walls with your own hands for a beginner. Videos and step-by-step instructions will help you understand the construction nuances.

The main purpose of the plaster is to level the geometry of wall and ceiling bases in order to eliminate irregularities or defects. It serves for rough finishing. The technology of application allows the mixture to be applied in a thick layer in case of large deviations. With the help of plastering the walls in the apartment, you can get the most even foundations.

According to its composition, plaster is of the following types:

The most important difference between them is the drying time of the solution.For a gypsum mortar, it takes up to a week for complete drying, for a cement mortar it will take about a month. Therefore, formulations with cement should be used when it is necessary to achieve maximum durability.

Such coverage will last for several decades. Modern manufacturers introduce polymer additives into the mortar mixture, which accelerate drying up to two days. The cement mixture is used for leveling surfaces in basements or for laying tiles.

The process of leveling the walls with plaster with your own hands is quite laborious, therefore, gypsum solutions are often used. With gypsum compounds, it is important to observe moisture conditions. You can apply gypsum plaster in one layer, which significantly saves your budget. The decoration is carried out both on a brick base and on wooden surfaces. For perfect smoothness, the coating should be putty after drying of the plaster.

It is important! In conditions of high humidity or temperature extremes, gypsum plaster should be abandoned in favor of cement.

For beginners, cement plaster with polymer additives is better suited for walls. Video tutorials will help you understand and painstakingly complete the entire process in compliance with the technological sequence.

A person who is far from construction terms will at first glance decide that these are synonyms for one type of construction work. In fact, these concepts have both similarities and significant differences. Both materials are designed to level surfaces, and this is where the similarity ends.

Plaster and putty - what is the difference and general features, in which cases they should be used, recommendations of experts - read about this and much more in our review.

Manufacturers offer a dry composition or a ready-made plastic solution. Cement, gypsum and polymers are added as binder. With the help of a putty, you can level out small surface defects, smooth the base after plastering. For cracks up to 10 millimeters in size, use the starting composition. The finishing putty is used for the final leveling of surfaces.

It is impossible to mix starting and finishing putty. Compositions of different homogeneity can form additional defects on the bases.

With plaster, surfaces with deviations of up to 15 centimeters can be leveled. In addition, it acts as a thermal insulation for surfaces, in some cases additional moisture protection.

Plaster can be ordinary and decorative. The composition contains large grains. It is used as a roughing or structural topcoat.

When applying putty and plaster, different technologies are used. For plaster, this happens as follows:

the first layer is applied by the spraying method, with the help of which large surface defects are hidden. In addition, it serves as an additional adhesion with subsequent layers;
the execution of the middle layer ensures the leveling of surfaces;
finishing putty or cover - finally smoothes the base.

Decorative mixtures are applied according to individual technology. The plaster composition needs several days to dry completely, the putty is ready the next day.

Before carrying out repair work, it is necessary to study the features of the base of wall surfaces. The method of performing the work will depend on this. For even walls, a spatula and a level are enough. Bases with large defects and deviations can only be leveled using beacons. You may need a lot of the mixture. In this case, additional reinforcement should be made on the wall.

There are several rules for plastering walls:

first of all, the wall surfaces are cleaned and primed;
in the second stage, the bulk of the plaster is applied and distributed;
at the final stage, the base is covered and cleaned.

A video on how to properly plaster walls will help you to do all the work correctly:

plaster;
primer for pretreatment of wall bases;
beacons in case of large surface deviations;
a rule for aluminum plaster with a length of 2 m for pulling the composition and 2.5 m for installing beacons;
bubble level at least 2 meters long;
spatula 15 cm wide;
construction float;
trowel;
bucket;
a roller with a bath or a brush for a primer;
gloves;
perforator with a nozzle for mixing the mixture;
dowels, screws, Phillips screwdriver, metal scissors for cutting beacons;
hammer;
metal ironing;
roulette;
plumb line.

Some tools are already available in every home. You will have to buy or rent something. But this is not a tool for one repair, everything will come in handy in subsequent repairs. We can say - an investment in the future. Now we know what tools are needed to plaster the walls, we can start repairing.

To prepare cement plaster, mix the cement with sand in a 1: 3 ratio. Water is gradually poured into the composition with constant stirring. You should get a solution according to the consistency of sour cream of high fat content. Before mixing, you should read the instructions and recommendations of the manufacturer. If repair work is carried out in a room with high humidity, experts advise adding lime. It will take away excess moisture and make the microclimate more comfortable.

For surfaces made of concrete and aerated concrete blocks, it is recommended to use gypsum-lime plaster. Its plasticity is well adhered to the base. To prepare such a solution, gypsum is poured into a bucket of water in a thin stream, then everything should be quickly mixed by adding milk of lime. This mixture is applied quite easily, and will help beginners get their hands on finishing work.

For plastering walls with your own hands, you can buy a ready-made mixture, which is offered in a wide variety in construction hypermarkets and stores. This is the easiest preparatory work.

The workflow for preparing a surface for plastering begins with cleaning the substrates from previous coatings. After that, the level should determine the magnitude of the deviations in order to determine whether the installation of beacons is necessary or if you can do without additional work.

Then prime all substrates thoroughly with a brush or roller. It is necessary to choose a deep penetration primer, there is no need to save on the composition at this stage, this will help the putty to adhere well to the surfaces. In addition, it protects the walls from excess moisture and prevents mold and mildew damage, which can corrode the material.
