The choice of putty
Before starting work, you need to decide how to putty the walls for painting. The choice of material depends on the location of the repair, as well as the budget allocated for the construction.
Types of putty:
- Starting lineup. It is a coarse-grained mixture. It is used to level the building base and mask defects.
- The finish tool. This is a fine-grained composition. Used for finishing putty. Levels the surface and prepares for painting.
- Universal composition. It is used both for starting putty and for the finishing layer.
Putty is also classified by readiness for use:
- The finished product. Available in hermetically sealed buckets of various sizes. The composition has the desired density and does not need to be prepared. The product is easy to apply to the surface. The disadvantage is the high cost.
- Dry mix. Available in paper bags. To prepare the product, you need a drill with a mixer nozzle. If there is no tool, then it is recommended to refuse to buy a dry composition, since it will be difficult to manually knead the composition of the desired density. Putty advantage - reasonable price.
The tool is classified by composition:
- Oil-glue agent. It is used with caution, since the composition contains drying oil, from which spots appear on the surface. Putty is recommended for use in rooms with high humidity. The composition is also used for wooden surfaces, as it protects the material from decay.
- Gypsum and cement. Putty is produced in the form of a dry composition, therefore, it needs preliminary preparation.
- Water dispersion composition. Sold ready-made. The product is made on a water-polymer basis. Easy to apply and smooth. Putty is recommended for use by masters without construction experience.
- Acrylic and polymer composition. The product is easy to apply and suitable for any paint. The disadvantage is the high cost.
Based on these data, the type of putty that meets the criteria of the master is selected.

Surface preparation
Before applying putty, a surface is prepared. All old coatings are removed and the walls are cleaned of dust and dirt.If after removing old materials on the building base numerous defects are found, then they are repaired with plaster. Next, the construction base is primed. It is recommended to use a deep penetration composition. The product is applied in two layers and after each application the work is suspended to dry the composition. After this, the surface is putty.
Putty preparation
If a finished composition is used for puttying the walls, then it does not need preparation. The bucket is opened and work begins. If a dry composition is used, then it must be prepared before use. The mixture is mixed with water in the proportions indicated on the package. Next, the composition is mixed with a drill nozzle mixer. The result should be a mass with a thick consistency.

- Grinding the base. To do this, use a grater or sandpaper. Before grinding, glasses and a respirator are worn.
- Drawing a layer of finishing composition. Thickness - 1 mm.

- Caps of self-tapping screws are closed. For this, the finishing composition is used.
- The areas on which the putty was applied are sanded. After this, a primer is applied.
