The surface should be dry, clean and even, without cracks and chips. Many believe that a decorative coating can be applied to an uneven wall and thus hide its serious errors. This is not true. Smoothing the walls with putty is more economically feasible than the more expensive decorative plaster, which also has a limitation on the thickness of the layer. A coarse-grained and thick-layer coating is able to hide only minor flaws and roughness of the walls. And for most thin-layer interior materials, perfect alignment for painting is required. Simply check this website for having a clear sense of what Polished plastering is and how it actually offers you a great quality.
Preparation of the base is a very important stage. Not only has the quality of the finished coating depended on it, but also its service life.
- The base must be primed with a deep penetrating water dispersion primer, for example, G30. This is a professional primer that will solve many different problems,dusting the surface, enhancing the adhesion of subsequent layers, leveling the absorbency of the substrate.
- For heavy thick-layer materials, the adhesion should be very good, therefore, for them as a basis, it is also necessary to apply a special primer for decorative coatings. This primer contains marble chips, so it creates an opaque, rough coating, similar to sandpaper. And for smooth coatings, we recommend using interior paint as a primer. The professional services are there and that is the reason you need to be choosy.
Application of the base layer
At this stage, with the help of decorative plaster, various tools and the skill of the master, a unique masterpiece is created on the wall. If desired, the decorative coating can be pre-tinted by a computer method in the tinting system or manually with water tints.
Using a trowel or a roller, a layer of the required thickness is applied to the wall, after which, depending on the desired result, the texture is formed by various tools: a trowel, a spatula, a brush, a textured roller, a decorative brush and a stamp, and others. For some effects, several layers of decorative coating are applied.
Application of the top coat
An interesting solution for many interior decorative effects is finishing waxes and varnishes, which serve not only to give color and emphasize the texture, but also to protect against pollution and moisture. This stage is not always applicable, it all depends on the effect.
The technology for applying decorative plaster is simple. Each coating requires a preliminary leveling of the surface using soil, then plaster layers are applied (the method of application varies depending on the desired effect). After drying, the surface is coated with paint or wax to protect against moisture.
Due to the fact that the range of decorative plasters is very wide, there are no uniform recommendations and standards for applying plaster. The main aspect is the thorough preliminary preparation of the surface. It is also worth noting that using the same material you can create completely different effects.
