Causes of cracks in walls

You must ascertain what caused the wall cracks to appear in order to remove them from it.

1. Incorrect proportions of putty and its application.
2. Insufficient surface treatment.

You have to adhere to the defect repair instructions to the letter in order to prevent bad things from happening. Using the appropriate crack sealing compound is also crucial.

Preparation of the solution

Learn the ideal dosage and application guidelines for the working mixture before you start caulking the cracks in the wall. The packaging has all the information you need. You will be able to rule out unfavorable occurrences in the future after studying it.

The ratios and technique for mixing the mixture are described in the instructions.

1. The container in which the raw materials will be mixed must be clean. No dirt or residues of any substances are allowed. Otherwise, the quality of the finished product will be greatly reduced.
2. To dilute the dry powder, it is worth using clean water that does not contain foreign impurities and components.
3. When mixing the components, it is better to use a professional tool that provides a choice of operating modes. It is recommended to perform the procedure at low speeds, avoiding the appearance of foam in the mixture.
4. In terms of viscosity, the consistency should be similar to thick sour cream.

If you don’t want to manually mix the putty to seal cracks, you can purchase a ready-made solution that doesn’t require any prep work before application. In addition, the cost of a package containing this mixture will be significantly more than the initial cost of the raw ingredients used in the mixing process.

Surface preparation

Without careful processing of the coating, wall surfaces cannot be covered with high-quality cladding. In certain instances, the process is labor-intensive and time-consuming. This also holds true for old buildings’ wall preparation. Since work has an impact on the finish’s dependability and durability, it should be handled carefully.

1. The painted surface, which was covered with water emulsion, is better to clean with a sponge moistened in hot liquid. If the layer cannot be removed, you will need to use a wire brush.
2. To remove oil-based dyes from the surface, you need to buy special removers. It is better to erase a thick layer using a special attachment on a grinder or electric drill.
3. To remove old wallpaper with a spatula, they are pre-moistened with warm water. If the material fit tightly against the wall, it is better to iron it with an iron through a rag. Under the influence of steam, the stripes quickly peel off the surface.
4. Fat and rusty spots are eliminated by special solvents.

The wall that has been purified is processed using a primer. Using a brush or painting roller, apply this mixture in a single layer.

Such actions will increase the adhesion level and provide additional protection to the surface from mold and fungus. You should wait for the primer to completely dry out before proceeding to the following step.

Tools

1. Putty knife. With it, you can close all the cracks. It is recommended to prepare 2 tools: narrow and wide.
2. Pure capacity for putty mixture. It should not have the remaining solutions or small inclusions. To mix the ingredients, it is better to prepare a small container.
3. Brush. Necessary for the distribution of the primer.
4. Stiff brush. With its help, the coating will be cleaned of small pollution.
5. Reinforcing layer. It is necessary to strengthen cracks that have a size of 2 mm.
6. Sandpaper. Will allow grinding surface.
7. V-shaped spatula. Intended for cutting cracks. Can be replaced with a scraper.

Application of the solution

1. First, putty of cracks, dents or cracks is performed.
2. Then a leveling primer is applied, which is thoroughly rubbed and distributed on the surface. The processed area is left for a day for final drying.
3. At the next stage, re -processing of the primer is carried out. It is important to wait a few hours so that this layer is completely dry.
4. The finish layer of putty. It should be smoothed out to exclude the problem of the formation of dents. After completing the processing, you need to wait at least a day for the solution to dry.
5. Using sandpaper, it is worth getting rid of all the irregularities and roughness on the surface.
6. Next, you should distribute the finishing primer layer and wait for it to dry.

If every step is finished accurately, you can move on to the final tasks, like wallpapering.
