Roller plaster - facing building material, thanks to which you can easily create a relief surface. After application and some manipulations, a pattern with various furrows forms 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 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 this 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:
- universality (you can decorate both internal and external walls);
- high adhesion (it holds well on brick, concrete, drywall and other surfaces due to the presence of acrylic binders in the composition);
- water and weather resistance (does not deform from rain, ultraviolet rays and does not deteriorate in the cold);
- forms the so-called breathable coating, due to which the optimal microclimate will be preserved in the room;
- lends itself to coloring in different colors (for this it is enough to add tinting paste of the desired shade);
- increased strength and wear resistance;
- environmental friendliness.
The shelf life of roller plaster is 18 months, if stored in a tightly closed container at a temperature of 0 ... + 30 ° . According to the masters of decorating, the lack of material is the high price (18 kg - about 1.5 thousand rubles).
The main types and composition
VGT roller plaster is sold in buckets of 9 and 18 kg. The composition of the material includes the following main components:
- natural marble chips;
- water;
- various decorative additives;
- acrylic binder.
Plaster is classified by 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, walls of offices and large halls.
- A medium-grained texture with a crumb diameter of 1.5–2 mm. This material is recommended to plaster the walls in rooms with high humidity.
- Fine-grained with a grain diameter of 1–1.5 mm. This type of decoration 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 bark beetle plaster 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, masters recommend entrusting the implementation of this process to specialists who can use tinting machines. However, the surface finished with plaster can be painted after application. To decorate the finished coating, according to the reviews of the masters, it is better to use acrylic or pearlescent paints. Thanks to the latter, it will be possible to create the effect of a marble surface.
Initial Stage - Wall Preparation
Use bark beetle plaster for finishing vertical surfaces, since it is not a leveling material. If you need to clad the facade of a building, then such a coating will retain its original appearance for 9 years. On indoor walls, 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 traces of nails or screws remain on the wall, the coating must first be treated with a moisture-proof primer. To do this, use a brush or brush and paint roller.
- The surface must be cleaned of old lime, plaster, wallpaper or other facing materials. The most difficult thing is to remove the “stubborn” paint, because, according to the masters, it can only be knocked down with an hatchet.
- Walls must be thoroughly cleaned of greasy stains, dust and dirt.
- Irregularities and cracks must be repaired with a gypsum mixture.
- Before decorating the walls with decorative roller plaster with the effect of "bark beetle", they must be treated with an acrylic primer of deep penetration. After 24 hours, the surface will become rough.
Necessary tools
For plastering work you will need:
- stainless steel spatulas (small - 100 mm, and wide - 300 mm);
- plastic or Venetian trowel to create a picture;
- a container (for example, a bucket) for warm water to periodically clean the frozen mixture in the tools in it;
- drill with mixer nozzle;
- small.
Basic application method
It is advisable to carry out work in dry conditions at an air temperature of at least +7 ° C. Roller plaster must be applied on the right side. First you need to thoroughly mix the mixture with a drill, and if it does not have the desired viscosity, no more than 5% of the total solution volume can be added to it. With a small 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 gaps do not form, since the mixture quickly solidifies.
The recommended layer of plaster is 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 turns out to create the desired textured pattern. When the layer begins to dry, you can begin to perform decorative finishes. As a rule, after a few minutes, the applied mixture will begin to lose its luster.
Roller plaster: methods of applying a decorative pattern
There are such popular patterns:
- Vertical - a method for which you need to press the trowel against the wall and, moving the tool from top to bottom, create a picture.
- Circular - a way to decorate a wall using arbitrary movements. The result is circles of different diameters.
- Inhomogeneous coating - a picture that needs to be designed in this way: make a line with a trowel in a checkerboard pattern. The result should be some imitation of the interweaving of bands.
- A cross-shaped option, for the implementation of which you must first apply long vertical stripes, and then decorate them with short horizontal lines.
- The "rain" method - rubbing from right to left along diagonal lines.
The final stage is to gently grind the surface with a dry spatula to smooth sharp corners and give uniformity to the texture. Roller plaster with the effect of "bark beetle" will dry 30 minutes after application, so you need to perform these works immediately after creating an aesthetic pattern.
Surface tinting
To paint the walls lined with roller plaster, you will need such items:
- foam sponge;
- paint roller;
- brush and brush.
The best option is double staining. To do this, you need to apply a thick layer of paint with a roller so that it fills all the recesses. If smudges appear, they must immediately be removed 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 in convex places.
Conclusion
Facing the walls of a stucco roller is a simple task. Buyers generally respond positively to this finishing material. They note its high quality and the fact that with its help you can easily make original and aesthetic drawings on the walls. You can buy such a mixture in any hardware store. According to buyers, about 2 kg of plaster will be required per 1 m 2 . However, some argue that, in fact, the consumption exceeds the rate declared by the manufacturer.
