Puttying concrete walls is not an easy task,but if you put in some effort, you can do it yourself. The concrete wall will look perfect in this case. Before you start this process, you need to properly prepare the base of the walls. They should be completely cleaned of dirt and dust, mold, fungus. You need to get rid of the old wallpaper, and if there is old putty underneath, you also need to get rid of it.

This must be done to ensure that the adhesion to the concrete wall is strong. The choice of material to be used for filling concrete walls depends on the quality of the concrete walls and how the work will be carried out in the future after the filling of the walls is completed. What will be needed to ensure that such work is carried out as efficiently and quickly as possible?
All these tools can be purchased at any hardware store.
Tools for filling concrete walls.If the walls are not even, then it is necessary to carry out the procedure of leveling the concrete walls. This is done using a starting putty, using a nylon mesh. As for the preparation of this material, everything must be done strictly according to the instructions that come with the putty. Take a clean container, pour water into it, then add the dry mass of putty (this must be done in this order, and not vice versa), after which everything is thoroughly whipped until you get a consistency that resembles thick oil. Doing this with your own hands is not at all difficult.
Starting wall plastering
Now you can start filling the concrete walls.Take a 100 mm spatula with your left hand and collect the material from the container. Then put it on a 450 mm spatula, it should be wide, and hold it with your right hand. Apply the material to the concrete wall with a light movement of your right hand in a thin layer. The strip should be equal to the width of the nylon mesh. Do all this from the floor to the ceiling, after which you need to glue the mesh to the treated area. Apply the putty layer so that the mesh of the initial putty is completely covered. As for the next piece of mesh, it needs to be laid evenly overlapping the previous piece. This is how you should putty the concrete wall of the entire room. You should wait until it all dries completely, this can take up to 2 days. Then you need to get rid of all the unevenness with sandpaper, and for these purposes you can also use an abrasive mesh on a special grater platform. After the grinding process is completed, you should carefully remove the dust with a vacuum cleaner or a damp cloth. If you skip this stage of the work, the consequences can be very negative. It is necessary to take into account the fact that there are no trifles in this process. Return to the table of contents</a>Finishing puttying of walls
Scheme of filling seams.Now it's time to start the main work. The material for this is made in the same way as the starting one, you must strictly follow the instructions indicated on the package. The consistency of the putty should be similar to thick sour cream, only a little thinner. A thin layer is applied to the walls with light hand movements from right to left (you can do it the other way around), the layer thickness should not exceed 2 mm. Then, with a 40-mm spatula, the material is leveled behind pipes and in other hard-to-reach places. It often happens that a person who has no experience in such work does not do the puttying in the best possible way. There is nothing wrong with this, since you just need to repeat this procedure. Only at the second stage, the material is applied with a thickness of 1 mm, from top to bottom. After everything has completely dried, new sanding is necessary, and then you need to get rid of the dust. At the final stage of the work, the wall should be covered with a primer, a velor roller is very suitable for this. All this must be thoroughly rubbed, the presence of drips is absolutely unacceptable. At this point, we can consider that all the work has come to an end and begin gluing the wallpaper. It becomes clear that there is nothing super complicated in carrying out such a process, everything can be done independently. And it must be taken into account that if you entrust such work to specialists, then it can be very expensive and the quality of the work is also not guaranteed. But it should be borne in mind that all the materials that will be needed for such work must be of the highest quality. The use of inexpensive and low-quality materials can lead to the fact that repairs will be needed very soon. Therefore, it is better to do everything right away in a high-quality manner and be calm.
