Roller plaster is a facing building material, thanks to which you can easily create a relief surface. After application and some manipulations, a pattern with various grooves is formed on the wall. Such a coating looks attractive and original. Therefore, the purpose of the article is to tell the reader in detail what advantages roller plaster has. In addition, its varieties and optimal application methods will be considered.
Features
Roller plaster is used for finishing facades, interior walls and rooms with high operational load. The latter include flights of stairs, offices, corridors, platforms, etc. Sometimes such plaster is called “bark beetle”, because thanks to it it is possible to make an original structure in the form of grooves on the surface. The advantages, according to builders, of this finishing material include the following characteristics:
- versatility(you can decorate both internal and external walls);
- high adhesion (it keeps well on brick, concrete, drywall and other surfaces due to the presence of acrylic binders);
- water and weather resistance (does not deform from rain, ultraviolet rays and does not deteriorate in the cold);
- forms a so-called breathable coating, thanks to which the optimal microclimate will be maintained in the room;
- can be dyed in different colors (for this, just add a tinting paste of the desired shade);
- increased strength and wear resistance;
- sustainable.
The shelf life of roller plaster is 18 months if stored in a tightly closed container at a temperature of 0 … +30 °C. According to the masters of finishing works, the lack of material is a high price (18 kg - approximately 1.5 thousand rubles).
Main types and composition
VGT roller plaster is sold in 9 and 18 kg buckets. The composition of the material includes the following main components:
- natural marble chips;
- water;
- various decorative additives;
- acrylic binder.
Plaster is classified according to the size of fractions into the following types:
- Coarse-grained (grain diameter - 2–2.5 mm). This variety, according to the masters, is best used for cladding facades, finishing the walls of offices and large halls.
- Medium-grained texture, the crumb diameter of which is 1,5–2 mm. This material is recommended for plastering walls in rooms with a high level of humidity.
- Fine-grained, the grain diameter of which is 1–1.5 mm. This type of finishing material is best used for wall decoration in small rooms and corridors.
For certain design ideas, a suitable fraction size is needed, since the relief and depth of the picture depend on this parameter.
VGT roller plaster "bark beetle" is available only in white, so it can be painted if necessary. According to people, in order to change the color of the material, you need to have professional skills. Therefore, the masters recommend entrusting this process to specialists who know how to use tinting machines. However, the surface finished with plaster can be painted after application. Decorate the finished coating, according to the masters, it is better with acrylic or mother-of-pearl paints. Thanks to the latter, it will be possible to create the effect of a marble surface.
The initial stage is the preparation of the walls
It is necessary to use bark beetle plaster for finishing vertical surfaces, since it is not a leveling material. If you need to clad the facade of the building, then such a coating will retain its original appearance for 9 years. On the walls indoors, it will last longer (at least 15 years). However, before applying roller plaster, it is necessary to prepare the surface, taking into account the following requirements:
- If there are footprints on the wallfrom nails or screws, the coating must first be treated with a moisture-proof primer. To perform these works, use a paint brush or a paint roller.
- The surface must be cleaned of old lime, plaster, wallpaper or other facing materials. The most difficult thing is to remove the "stuck" paint, because, according to the masters, it can only be knocked down with a hatchet.
- Walls must be thoroughly cleaned of greasy stains, dust and dirt.
- Irregularities and cracks must be repaired with a plaster mix.
- Before finishing the walls with decorative roller plaster with the “bark beetle” effect, they must be treated with a deep penetration acrylic primer. After 24 hours, the surface will become rough.
Required tools
For plastering you will need:
- stainless steel spatulas (small size 100mm, wide 300mm);
- plastic or Venetian trowel to create a pattern;
- a container (for example, a bucket) for warm water to periodically clean the tools in it from the frozen mixture;
- drill with mixer attachment;
- malka.
Main application method
It is desirable to carry out work in dry conditions at an air temperature of at least +7 °С. Roller plaster must be applied on the right side. First you need to thoroughly stir the mixture with a drill, and if it does not have the desired viscosity, you can add no more than 5% of water from the total volume of the solution to it. smallwith a spatula, you need to carefully collect the required amount of facing material and transfer it to a wide tool. The next step is to apply an even layer to the prepared surface. The main thing is that there are no gaps, as the mixture hardens quickly.
Recommended plaster layer - 3–5 mm. The complexity of the described works is that they cannot be interrupted until the entire planned surface is finished. According to the masters, it is difficult to combine dried areas into a single composition. In addition, the excess must be periodically removed with a spatula, so that in the end it will be possible to create the desired textured pattern. When the layer begins to dry, you can begin to perform decorative finishes. As a rule, the applied mixture will begin to lose shine after a few minutes.
Roller plaster: ways to apply a decorative pattern
There are such popular pattern options:
- Vertical - a method for which you need to press the trowel against the wall and, moving the tool from top to bottom, create a pattern.
- Circular - a way to decorate a wall with arbitrary movements. The result will be circles of different diameters.
- Heterogeneous coating - a drawing that needs to be drawn up in this way: make a checkerboard line with a trowel. The result should be a kind of imitation of weaving stripes.
- Cruciform option, for the implementation of which you first need to apply long vertical stripes, and then decorate them with short horizontal lines.
- Rain method - mashing on the rightto the left along diagonal lines.
The final step is to gently sand the surface with a dry spatula to smooth out sharp corners and give the texture a uniformity. Bark beetle effect roller plaster will dry in 30 minutes after application, so these works should be done immediately after creating an aesthetic pattern.
Surface tinting
To paint the walls lined with roller plaster, you will need the following items:
- foam sponge;
- paint roller;
- brush and brush.
The best option is double staining. To perform it, you need to apply a thick layer of paint with a roller so that it fills all the recesses. If smudges appear, they must be removed immediately with a sponge or roller. After the layer has dried, it is necessary to treat the surface with a paint of a different color, but so that it remains only on convex places.
Conclusion
It's a simple task to cover the walls with roller plaster. Buyers generally respond positively to this finishing material. They note its high quality and the fact that with it you can easily make original and aesthetic drawings on the walls. You can buy such a mixture at any hardware store. According to buyers, 1 m2 will require approximately 2 kg of plaster. However, some argue that in fact the consumption exceeds the figure declared by the manufacturer.
