In its popularity today, textured plaster in the interior, in the kitchen, is especially one of the most popular coatings, which allows you to arrange your home in any style without unnecessary efforts and costs. It makes it possible to create complex drawings and decorative surfaces that simulate both natural materials and complex reliefs. The technology of application is not particularly difficult, which is why this work is fully for the power of the home master.
How to make textured plaster – the main types of material

Manufacturers offer a wide selection of finishing materials. This is a white viscous mass. Its main component is mineral granules, thanks to which the relief is obtained. The size of the grains, their shape and type of filler form the texture and appearance of the surface. The binding components can be acrylic material, lime, polymers, epoxy resin, polyurethane. They form the internal properties of the coating – vapor permeability and durability.
A certain level of density creates various chemical additives. Before asking the question of how to carry out work, you should deal with its types of plaster and characteristics. Plastering coatings, depending on the binder used, are divided into several types:
Acrylic;
silicone;
mineral;
silicate.
The most popular and affordable look is mineral. This is a dry mix with good fire resistance and vapor permeability. The introduction of special additives gives it antibacterial, reinforcing and thermal insulation properties. It is based on cement and sand. The time for the complete setting of the plaster – 28 days. Of the disadvantages, one can indicate the inelasticity of the coating, which is the result of insufficient resistance to cracks appearing on the surface, as well as a relatively short service life. Such plaster, in addition, requires a responsible approach to preparing the base and the need to constant stirring the solution during operation.
Acrylic – a mixture of pasty consistency, ready for use. Made on the basis of acrylic polymer binding material. The composition is elastic, holds well on the surface and camouflages small cracks, indispensable for decoration in newly highlighted buildings, where shrinkage is possible. It is easily applied to the wall and dries quickly (depending on the conditions of the external environment – up to 24 hours), it can be given any color. Small granularity makes it possible to model the drawing and anticipate the consumption of the material. The disadvantages include fading, the ability to attract dust, parony permeability and high price. To avoid fading, plaster is covered with special varnish or paint. Slashery of operation – approximately 20 years.
Silicate – the mixture is already ready for use, made on the basis of compounds of sodium and potassium silicates – (“liquid glass”). The surface is durable, washed, practical, plastic, has high vapor permeability, antistatic. Surface readiness – depending on weather conditions up to 48 hours. Can be used on facades of houses, with the restoration of ancient buildings, with increased humidity. Operating life up to 25 years. Disadvantages: insufficient spectrum of colors and high price.
Silicone – a mixture made on the basis of silicone resins is ready for use. Has good water – and dirt -repellent properties. Unpretentious in care, has antistatic properties, vapor permeable, durable, elastic. Operating life up to 25 years. Surface hardening time – about a day. Due to the high price, it is used less often than other types of finishes.
Dry mixtures have a lesser shelf life in comparison with ready -made ones, but it is more convenient to store them. The use of convenient mixtures is more convenient. The consumption of textured plaster largely depends on the size of the grain (the consumption is greater than the larger grain) and adhesion to the surface. It looks better in the room with small diameters, and on the facades – a large. Mineral plaster dries the longest. Acrylics can be tinted in any color.
Preparatory work
Master class on applying decorative structural plaster
The plaster of the walls has been served for many years and at the same time has a magnificent look. Before applying the first layer, it is necessary to pre -prepare the surface of the wall. It is cleaned of pollution, various oils, dust and fat. If the wall has great bumps, then they must be leveled. Wallpaper or chalk coatings are removed. Wall painted with paint, thoroughly washed with soap solution. Cracks are glued with a painting grid and put down.
The wall should absorb moisture well, and also be dry, even. Then the surface is treated with a primer of deep penetration, after which it is completely dried. The deeper the primer penetrates, the durable and better the coating will be. The wall decoration of textured plaster is carried out when the primer is completely dry (at least 6 hours).
Treaty wall plaster with your own hands – technology for execution
Wall decoration is carried out using a metal ironer or a wide spatula. Plaster is applied up to 5 millimeters with an even layer. Time of “Life” of the cooked mixture – 20 minutes. Dried residues are removed mechanically, not frozen – you can wash off with water.
If you work with plaster type “lamb”, then the custody filler will create an original structure during application. Solutions containing a filler with a small fraction give a smoother surface.
A special embossed pattern is obtained when rolling a special relief roller on freshly plastered plaster. If the relief is rude or too pronounced, it can immediately be smoothed out with a soft brush.
What kind of design solutions allows you to realize textured plaster, video lessons will help to deal with all the possibilities step by step.
