During the finishing of the premises, a variety of works are performed: plastering, facing, painting, wallpaper, and glass work. Plastering and painting work on the ceiling is carried out until the floor is installed, after which wallpapering and final glazing are carried out. Finishing also includes painting or varnishing wood floors.
Consumables are materials used in the preparation of various compositions for finishing premises. These are adhesives, putties, primers, dry mixes. Consumables also include nails, pipes, taps, wires, and more. Finishing materials are the materials used for finishing:
– ceilings (paint, stretch ceilings, decorative panels, etc.);
– walls (paint, wallpaper, decorative coatings, decorative panels, etc.);
– floors (parquet, linoleum, tiles, etc.);
– plumbing fixtures (bath, toilet, washbasin, etc.);
– joinery (windows, doors, etc.);
– wiring accessories.
Lime and lime-gypsum mortars are used for internal plastering. Complex and cement mortars are intended for outdoor decoration. But sometimes they are also used for interior plastering. Premises with an air humidity of no more than 60% with stone and concrete walls, concrete floors are plastered with lime or complex mortars. For wooden and plaster walls and partitions, wooden floors, lime-gypsum solutions are used. Rooms with high humidity (bathrooms, baths), plinths, external slopes, cornices, parapets are plastered with cement and cement-lime mortars. Plastering work can begin after the completion of the installation of floors (including backfilling them with insulation), the installation of partitions, window frames and doors with a hinge of window sashes and door leaves, as well as the construction of stoves and fireplaces.
In order to prepare the wall for plastering, it should be thoroughly cleaned of dust and dirt, rinsed with water. And if it is dry and clean, then you can only moisten it. If the surface of the wall is very smooth, then notches are applied to it to impart a roughness that increases the adhesion of the solution..
There is no need to plaster metal surfaces, it is enough just to paint them. But, for example, when plastering window and door lintels made of scraps of T-metal (beams or old rails), they are pre-wrapped with wire or wrapped in steel mesh.
Decorative textured coatings perform a decorative and protective function. They form a texture on the surface and do not require further processing or finishing and can be applied to walls and partitions made of any material (brick, concrete, drywall, wood, ordinary plaster). The coatings are available as a ready-to-use thick mix or as a dry mix. They are based on:
– polymeric binder; – filler (marble or granite chips, sand, lime), on which the consistency and texture of the coating depends;
– liquid base (water).
They are used for both interior and exterior decoration. Their undoubted advantages are:
– high decorative properties;
– high strength;
– heat and sound insulation qualities;
– protective properties that prevent corrosion, mold, condensation;
– fire safety.
The disadvantages include:
– sufficiently fast hardening, which makes it difficult to carry out finishing work on the surface of a large wall and requires quick work.
If the coating is made as a dry mix, it must be diluted with water in the correct proportion. The solution is applied quickly enough: either first with a brush and then with a spatula or other tool, or with a special tool right away. With the help of various molding tools, you can additionally create different types of texture.
Keep in mind that various types of coatings are used for wall decoration, which have particularities when applied or mounted on the wall. When building a house or renovating an apartment, determine in advance which coatings will be used in which room in order to properly prepare the wall. The walls must be prepared using the appropriate in each case rough materials (primers, fillers), including for leveling the surface, sealing cracks.
By the way, there are special types of wall coverings that not only have a decorative function, but also have additional properties (non-combustibility, increased sound insulation properties).
The price for such coatings varies and it depends:
– from the manufacturer (imported coatings, especially those produced by well-known manufacturers, are more expensive);
– on the quality (coatings with additives, finishes with additional protective properties are more expensive);
– from the presence of manual work (the higher the percentage of manual work, the more expensive);
– on the composition of the coating (coatings made of natural materials are more expensive than synthetic ones).
