The main stage - putty

Quite often, users wonder whether it is necessary to putty the walls after plastering. This stage of work is mandatory, because the purpose of the previous steps is only to prepare the walls.

The choice of putty

To get a perfectly flat surface for finishing, you should understand what to do with the walls after plastering. To do this, determine which putty to choose. Depending on the structure of the mixture, 3 types are distinguished:

1. Home – with a granular consistency, based on quartz sand. Used for primary processing, i.e. elimination of the largest defects, cracks.
2. Finishing - fine fraction, superimposed on the starting one with a small layer within 2 mm. The result is a glossy surface that is easy to sand.
3. Studying what to do next after cement plaster, you can consider the application universal plaster, which combines the functions of starting and finishing. Such a composition is applied in one layer and simplifies the work, but is more expensive.

Considering the better to putty the walls after plastering, you need to get acquainted with the types of mixtures depending on their composition:

1. Cement - the most common, versatile variety that can be used to work outside and inside. It is resistant to humidity, temperature changes and sunlight.
2. Gypsum - very plastic, allow you to achieve a perfectly flat surface, are used only for interior work. When the walls are plastered, it is planned what to do next. If you need to paint, it is gypsum putty that is best suited.
3. Polymer based on acrylic, latex, polymer cement. These are particularly resistant compositions that will not suffer from high humidity or temperature changes. They are more expensive, but they last a long time.

How to putty walls

Now it’s clear what to do next when the walls are plastered - you need to start puttying. The work is carried out in several stages, and each of them uses its own tools:

1. Prepare the solution according to the instructions and proceed to the starting putty. This requires a large spatula. It is held at an angle to the wall of about 30o. The composition is applied, moving in a diagonal direction. You can also overlap the layers so that there are no bumps.
2. The next stage after plastering the walls is the processing of even corners. For this, an angled spatula and a small spatula are used. The last composition is applied to the slope with a small layer, and the corner is carefully leveled.
3. Finishing - At this stage, you will need a large and small spatula. In this case, the composition is laid in a small layer within 2 mm. A small tool is used to lay the composition on a large one, after which it is distributed over the surface.
4. When the previous layers are completely dry, you need to figure out how to level the walls after plastering. To do this, use the same tools (spatulas of different sizes). The composition is applied with a second layer and then proceed to wallpapering or painting.

Finishing

When the walls are ready after plastering, what to do next is also quite clear. It is necessary to start finishing (final) finishing - this is painting or wallpapering.

Painting

After puttying, the composition must be given at least a day to dry. Then the walls are carefully examined, directing oblique rays of light, and go through with sandpaper. Further processing is carried out with a vacuum cleaner and a hair brush to remove residual dust. There is no doubt whether putty is needed after plastering. It is she who provides a perfectly flat surface, which can be additionally checked by swiping with a damp sponge. If a dark spot remains, the moisture has absorbed, it is necessary to go through the primer, and only after that you can start painting.

Wallpapering

If, after plastering the walls, wallpapering is planned, it is quite enough to lay only the starting composition. Next, check how the wallpaper will look. After drying, the fragment is glued to the surface and see if yellowish spots appear. If everything is in order, the wall needs to be sanded, dust removed and wallpaper paste applied. Then dry again and proceed to pasting.
