Tools and materials
To create a decorative coating Grotto, you must use:
- gypsum plaster;
- wall paint;
- pearlescent pigment and varnish;
From the tools you will need a container for mixing the material, a spatula, sandpaper, a building level, a float and a trowel, a roller with a nap, a flexible spatula, a trowel, a suede mitten.
Preparation of the mixture
If the master decided to prepare the composition on his own, it is necessary dissolve the plaster in water and add the putty. Both components are mixed in equal proportions. The putty will give the composition plasticity and will not allow it to dry out prematurely. If you wish, you can use one plaster, but it is much more difficult to work with such a mixture.
The walls are pre-cleaned of dirt: old coatings, pieces of wallpaper, grease. Holes, potholes, cracks are closed and rubbed over. The surface must be primed for adhesion and dedusting.
The next preparatory stage is the application of quartz sand. This is done with a brush or roller. After 3-4 hours, the layer dries up and becomes suitable for plastering.
The first main layer is applied evenly, evenly, leaving no gaps.
Do not put the spatula in the bucket. You need to use an auxiliary tool so that the work is neat and of high quality.
The finished mixture is applied to a large trowel and spread with light movements on a flat metal spatula to create embossed decor (or a narrow ironer). It is applied to the wall, creating a uniform pattern across the entire wall. They move slowly, leaving the most identical islands with a slightly drawn solution.
20-30 minutes after application smooth the drawn mixture with a large trowel soaked in water... When the mixture adheres to the surface of the tool, use a conventional spatula. When the working area is smoothed, continue to apply the material to the rest of the walls.
After the final drying of the relief layer use a front spatula. They are passed along all the walls, eliminating sharp protrusions. At the end of the working process, they start painting with a roller with a long pile.
It gives a beautiful view to the interior pearlescent coating... When the paint dries, mix pearlescent pigment and primer 1: 1. The finished composition is applied with a foam roller (it is desirable that it be semi-dry). In this case, the pigment is evenly applied to the protruding edges.
When the pigment layer is dry, proceed to varnishing... To do this, use a roller equipped with a long pile. It is necessary to apply varnish on the walls twice to form a moisture-resistant surface.
