Decorative plaster for outdoor works
Who did not hear the famous phrase about what three things a man should do in his life? And one of them is to build a house. But here the house is built and it needs to be "dressed".And then comes a series of throwing and agony of choice. All men want the cover of the outer walls of the "patrimonial nest" to combine beauty and functionality.
And the choice of many of them stops on facade decorative plasters. Why so many buyers prefer this building material? Everything is very simple. Firstly, the plaster hides the irregularities in the masonry and the wall defects; secondly, it carries out the thermal, sound and waterproofing of the premises; third, it protects the external surface of the walls from moisture, mold, etc.
Facade decorative plaster depending on the type of filler can be: mineral, polymeric, silicone and silicate. We will tell briefly about each.
Mineral and polymeric plasters
Mineral plaster .Supplied as a dry mixture, which is based on white high-quality cement, diluted before use with water. This plaster is distinguished by high fire resistance, ecological compatibility and high vapor permeability. Applied to all mineral bases without exception. The price for plaster of this type is notable for its attractiveness.
The other side of the coin looks less optimistic, this mineral coating leaves much to be desired in terms of its elastic properties, and also has low adhesion. After application, this coating is structured with a special plastic float.
Polymer plaster .It is represented by a variety of subspecies, differing in the type of binding element. Polyurethanes, epoxy resins, polyvinyl acetate, acrylic, butadiene-styrene and styrene-acrylic dispersions act as it. The chemical composition of the binder component determines the technical characteristics of the coating.
Decorative plaster for outdoor works on the basis of polyvinyl acetate and acrylic dispersions is characterized by high water vapor permeability, excellent resistance to high temperatures, adhesion to the substrate and increased resistance to ultraviolet radiation.
Butane-styrene, as well as styrene-acrylic plasters, are characterized by increased resistance to precipitation. Decorative plaster of external walls, having a polymeric structure, has a mass of advantages. This technology, and durability, as well as strength and high adhesion. The sale is delivered ready for application and already shredded.
Silicone and silicate plasters
Silicone plasters .Manufactured on the basis of silicone resins and go on sale already ready for use. They are applied to all mineral substrates, as well as to old coatings treated with special silicone primers. This decorative plaster exterior on a silicone base has hydrophobicity, high vapor permeability, resistance to ultraviolet radiation and enviable longevity.
Another advantage of these plasters is the ability to self-clean. This is due to the siloxane fibers contained in these coatings, which literally tear off the dust. The disadvantage of this coating is not in the technical characteristics, but in a rather high cost. Due to its high hydrophobicity, it is often used as decorative plaster plinth.
Silicate-based coating .At the heart of these plasters is the technology of "liquid glass".Sold ready to use. They are used to cover any mineral bases, as well as old silicate coatings. The color scale of these plasters is not particularly diverse.
Facade decorative plaster - a good foundation is important
Preparation of the substrate for applying a layer of decorative plaster is done in several stages.
- If the wall has already been plastered before, clean the old covering.
- Remove from the wall all the rushes and mounds, which subsequently lead to thickening of the plaster layer and, accordingly, increased consumption of material, time and money.
- We clean the base of dirt.
- We shpatluem the wall.
- Priming the wall, letting it dry out and stuffing a special mesh.
- We install plastering beacons.
Finishing of facades with decorative plaster occurs with the use of such tools: various rollers, spatulas, grater, plumb.
There are a lot of videos on the Internet on the theme: "decorative plaster facades: video lessons", everyone can see them and decide whether he will independently apply plaster or invite a specialist from the side.
Decorative plaster of external walls - we work correctly
As many decorative plasters go on sale already ready for use, the briefly step-by-step instruction for applying looks like this:
- Stirring. It is necessary to mix the prepared mixture very carefully before applying.
- Application. An important obstacle in the process of working with decorative plaster can be a variety of weather phenomena. The ideal condition is the absence of wind, rain and direct sunlight. According to the recommendations of the manufacturers, the application should take place without interruptions, so that the working surface does not have time to dry out. You need to start from the top corner and down. Dock adjacent areas before drying the plaster layer.
- Grout. It is carried out by plastic "smoothing" immediately after application to the wall. Do not blow the foundation. It is very important that the grout is produced with the same amplitude and in the same direction.
As the work on applying decorative plaster to the facade requires certain skills and skill, the best solution will be to rely on the skill of professionals.
