As part of the decorative plaster ?

The different composition of the decorative plaster from the other kind of mixtures?

begin, as is customary, from the very beginning: how to cook a particular plaster.Cement-sand does not differ from the mortar to bind the bricks, the ratio of cement, sand and water are different, but the first two components are usually mixed at a ratio of 1 to 3.

On the basis of this composition is cement-lime mortar, however, the proportion of underadding lime paste from 0.2 to 1 part significantly changing - then placed over the sand 4 to 6 parts.If you do not use cement to give pure lime mortar, and if you add to it the plaster, stucco name will change to the corresponding derivative of the main components.

In principle, all the above is enough to have an idea of ​​the percentage of the components of plasters and their components.Decorative plaster are manufactured in much the same way.As for the main ingredients in the composition of the plaster is usually includes the main communication elements - cement or lime.

Plaster as a main component is rarely used due to the fact that such a composition solidifies in the next 10 minutes, that creates some difficulties in working with him .In addition to bases used composition fillers including sand, marble dust, cellulose fibers, as well as various plasticizers, defoamers, pigments, determining the properties of plaster.

What consistency should be part of the solution for plaster?

How good solution would be to go to the wall, and how much it will last there, is determined primarily by its viscosity.However, it should not be excessive, or when applying the plaster will roll down, but not distributed evenly.

Therefore, adding the next component of the plaster solution, watch for his density.It is best to mix and test mix special meter paddle, lifting it from the masses, you will immediately see how well the mixture.For machine plastering mixture should be slightly thinner than the manual.

If the plaster much sticks to an oar, it is desirable to add it in the filler, which is usually used sand.If on the contrary, it is not sticky solution, it is necessary to introduce a binder component - cement, lime or gypsum. In general, the composition is supposed to be the average fat content of just a little, not too thick, sticks to the paddle .To prepare such a composition of plaster with your hands not hard, just enough time to time to mix the necessary components to the desired proportions.

composition of Venetian plaster, and that such complex solutions

Price building material depends primarily on its composition, and is not always natural ingredients contribute to higher prices.Take for example at least a part of Venetian plaster.The main connecting element there may be lime or synthetic components.The simplest option - it slaked lime with a marble flour, vegetable dye, and water as a diluent, is much cheaper than synthetic analogue.

Decorative plaster, including the Venetian, there are water-based or epoxy resins as a binder.

If you prefer a more expensive blend with synthetic fillers, keep in mind that (God forbid, of course) happen a fire, a part of resin plaster begin to decompose with the release of harmful substances.

example, epoxy resin is isolated by 140 degrees chloro and polyurethanes - cyanide.Therefore, despite all the advantages of synthetic additives that provide better viscosity and plasticizing, try to stick to natural fillers make up the mixture of plaster.
