Putty painted walls

Hard putty of painted walls can be made, hard putty is also used when covering with wallpaper, these are two different options and the application system of the material is different. This is what will be discussed today.

You will learn about the different options for applying the material and the possible mixtures that are worth using. In the video in this article, you can see the main points of the work and select the desired finishing option from the photo, it can be modeling from putty on the wall or just curly.

Types of putty

Today in construction stores you can buy various types of putty, differing in composition, depending on the destination. It can be gypsum putty, cement and polymer (acrylic).

All of them have their advantages and disadvantages:

Based on the purpose, putties are divided into starting, finishing and universal:

The advantages of dry putties is that they can be stored for a long time, if you do not violate the storage technology. The construction industry, along with dry mixes, offers ready-made putties that do not require preparatory operations for their use.

They have their advantages and their disadvantages:

• The advantage of ready-mixed mixtures is that they can be used immediately, which saves a lot of time, and the quality indicators of such mixtures in the context of preparation should also be noted: nevertheless, it is possible to mix the putty mixture with high quality only in the factory. Only in this way can a high uniformity of the mixture structure be obtained.
• As for the disadvantages of such mixtures, first of all, it should be noted their high cost and limited shelf life.

Caution: If you make a purchase of dry mix in the winter, then never buy it on the street.It freezes and at the same time loses its properties.

What tool is needed for puttying

To carry out puttying work, you should purchase a certain set of tools:

1. An electric drill, which allows the use of a construction mixer, without which it is not possible to knead putty with high quality. Putty mixtures are largely produced dry. So that it can be used, a certain amount of water is added to it.
2. Several types of spatulas with different sizes. For puttying on small surfaces, a spatula with a width of 40-50 cm will be required, and for work in hard-to-reach places you will have to use the narrowest spatulas.
3. Paint rollers and brushes. They are needed both for painting putty surfaces and for applying a primer. A primer is necessary for more reliable adhesion of the next layer or layer of putty to a cement or concrete base.
4. The rule. You can’t do without the rule if you plan perfect wall decoration. Basically, a rule is used, with a length of 1.5 to 2 meters, with built-in indicators for the vertical and horizontal level.
5. In addition to the rule, it is desirable to have a building level that can replace the rule if a level wooden lath is used instead of the rule.
6. Hand skinner. It is intended for polishing finishing putty and has special clamps for fixing sandpaper.
7. Sandpaper. You can use coarser sandpaper to sand the intermediate layers, and sandpaper with a number of at least 100 is recommended for sanding the finish. To get a perfectly smooth surface, you will have to use the 240th skin.
8. To mix the putty, a container is required. As such a container, a construction plastic bucket is very suitable, which must be washed thoroughly after finishing puttying.

Surface preparation

If you read the instructions, then putty is recommended to be applied on a solid and clean surface, on which there are no traces of dirt, dust, paint or grease.

Attention: If there are any, then they should be removed by any available methods. It is also not recommended to putty on frozen surfaces.

If the walls meet all the necessary requirements, then you can proceed with further work, pre-coating the surface with a primer:

• The surface can be primed with a wide paint brush or roller (see Primer before puttying walls - is it needed).
• The surface should be primed very carefully so that there are no gaps. As a rule, a single primer coat with a high degree of penetration is sufficient.

Material application

The order of the putty on the walls is determined by the plane itself. If it is large, then it will be difficult to maintain the alignment of the application of the material. Then beacons will be used.

If the plane is not large, then just start first. Finishing is used for any application of the material.

Attention: Mechanical work in this option can only be when applying a fur coat, you all have to do all the other cases completely with your own hands.

Beacon Installation

To be more precise, this is a putty on the walls of the lighthouses as lighthouses, you can use wooden straight slats or purchase factory-made lighthouses in the building market.

We make the installation of beacons

• They are mounted on the walls with self-tapping screws or quick-drying gypsum putty.
• After this, the spaces between the beacons are filled with starting putty and, with the help of a flat rail or the rules are smoothed over the surface. Such an operation is carried out in such a way that the rail or rule rests on the beacons, which makes it possible to obtain a perfectly flat surface.

Attention: Puttying on beacons is very rarely used, since installing beacons takes up a lot of useful time, although this is compensated by the quality of the putty work performed. As a rule, puttying on lighthouses is an expensive pleasure, but for a large plane this option will allow you to do the job most efficiently.

Starting putty

Starting putty is indispensable if the working surface has large irregularities. These can be recesses, shells, or cracks that require sealing.

We start

So:

• The structure of the starting putty is rather rough, which makes it possible to apply it to the surface with a layer of up to 20 mm, moreover, in several layers.
• Before applying the next layer, you must give the opportunity to completely dry the previous layer.
• If the walls do not have sufficient strength, then before puttying, a paint net is nailed to the wall as a reinforcing material. It not only makes the surface more durable, but also makes it possible to align it well.
• The paint net can be either coarse or soft, and the greater the roughness of the surface, the coarser the mesh needs to be applied.

Finishing putty

The main purpose of finishing putty is the completion of the technological cycle of puttying. Coarse fractions are not included in its composition, which makes it possible to obtain a smooth surface.

We apply the finishing material

• Before applying the finish layer, you must remove from the surface the burrs and sag resulting from the application of the starting putty. To do this, you can use a manual skater, fixing it with a large grinding skin.
• If the previous operations were carried out poorly, it is unlikely that with the help of finishing putty radically increase the quality of the surface.
• Finishing putty does not have such strength as the starting one, and is easily processed with an emery cloth. To obtain a smooth surface, it is advisable to use a grinding skin of at least 100th number.

Attention: After applying this material, let the plane dry and be sure to grind. It will already be a mechanized putty on the walls, here you can perfectly apply a grinder. Its price is not high, but it will greatly facilitate the work.

Crack Sealing

Over time, during the operation of the house, cracks of various sizes appear on the walls. This is usually due to the shrinkage of the building.

Putty cracks

• In the process of repair work, before applying the putty on the walls, all cracks, large and small, should be repaired. To do this, you can use the starting putty, but in order to keep it better in the cracks, they need to be expanded (increased) and thoroughly treated with a primer.
• After this, you should wait until the putty hardens, after which you can begin to putty the walls, having previously primed them.

Putty application technology

To start working, you need to prepare a putty.

To do this, you must:

• Pour a small amount of water into the dishes;
• Pour putty from the bag;
• Mix;
• Bring the mixture to the desired consistency using an electric drill with a nozzle.

Caution: Putty mixture will be ready when its consistency begins to resemble thick sour cream. If it rests on a spatula, then the mixture is ready, but at the same time, you need to make sure that it is not too thick.

A quality mixture has a uniform structure, without lumps or lumps. If any, then putty, most likely, was not stored in proper conditions.

1. The first is putty putty. To do this, you can use a wide spatula, holding it at an angle of 30 degrees relative to the working surface, evenly distributing the mixture on the wall. As a rule, this is done in one motion diagonally.Each subsequent layer should be applied in the opposite direction, in order to avoid tubercles and sagging. During operation, it is recommended to knead the putty in small portions, since it quickly hardens (relatively), and small lumps may appear in the mixture that will interfere with normal operation.
2. The room has not only smooth walls, but also corners, both internal and external. Particular attention should be paid to the processing of internal corners. To do this, you can use an angled putty knife, if the angles have an angle of 90 degrees, otherwise everything depends on the skill of the puttyer. In any case, flaws can be corrected during the grinding process and excess putty can be easily removed. The processing of external corners is devoid of such a problem due to the fact that metal corners are usually installed on them, which also serve as original beacons.
3. After the starting putty has completely dried, you can begin to apply the finishing putty. The application technology is no different from the previous technology, but has some differences. The main difference is the thickness of the putty applied, which should not exceed 2 mm. Usually at least 2 such layers are applied. For putting putty in hard-to-reach places it is better to use narrow spatulas.
4. Somewhere 12 hours after applying the last coat, the putty is ready for sanding. Given the large area available, it is best to use an electric grinder to speed up the grinding process and ease work. During this operation, a lot of dust appears, therefore, it is advisable to use protective equipment and not breathe this “muck”. By the way, grinders can be connected to vacuum cleaners, which minimizes the appearance of harmful dust.

Attention: If the area is small, then a manual skater is used, in which the grinding sand is fixed using special clamps.

• For high-quality surface treatment, it is advisable to use carrying and constantly highlight grinding points.
• Grinding is carried out by wide, sweeping movements at the initial stage, with the transition to circular movements at the final stage. Using this technology, you can get a quality surface.

Putty walls for painting and wallpaper

Standard puttying technology (see How to putty walls correctly for painting - a detailed description of the process), but the various requirements that are imposed on the final result, although it is always necessary to putty quality, especially if it is not known what will happen next - painting or wallpaper.

Attention: The fact is that painting the walls can reveal all the flaws formed as a result of poor quality putty on the surface. Based on this, many refuse to paint the walls. Nowadays, walls are painted mainly in offices, shops, cafes or in administrative buildings, where the practicality of the painted surface is taken as the basis.

• As for the residential sector, preference is increasingly given to wallpaper. Here you can note many positive points. The main point is a wide selection of color and structural solutions, which is incomparable with a monotonously painted surface. At the same time, you can purchase wallpaper of such a structure when the quality of the putty surface goes by the wayside, the main thing is that the surface is smooth both in the vertical and horizontal plane.
• But in such a wide assortment there is a type of wallpaper that requires very careful grinding of the surface - this is silk-screen printing. They are able, after sticking, to isolate the smallest imperfections and to reveal the smallest dust particles. Yes, they are very beautiful, but very problematic.

Attention: Colored putty can also be used for work. For example, in non-residential premises, it can be applied as a finishing material.

If the clay walls are putty, then the old material is best removed completely.It may just be incompatible formulations. You have instructions for other surfaces and you can do everything without problems.
