Water-resistant putty - where and how to use ?

What is water-resistant putty?

The most common preparation for finishing is in alignment defects and the subsequent finish coating shpaklevanii certain type and destination.Obviously, not every putty composition may work under certain conditions, especially for building materials capricious humidity.

As is already clear, water-resistant putty need to prepare the walls and surfaces exposed to moisture in its various manifestations, TE evaporation, condensation, rain, fog and pr. The extensive list of such premises, in addition to a variety of external walls of buildings, there arekitchen, cooking facilities, saunas, bathrooms and others.

Key Features waterproof putty

Practically all water-resistant putty different formulations at its core is Portland cement.To obtain these materials are a mixture of clinker and gypsum.When this dry mixture having a powder structure.For its transformation into solid cements need the presence of water in a certain ratio.

Only for positive values ​​of the ambient temperature, the liquid mixture of mortar hardens.Moreover, more often on such surface moisture is deposited, the deposited layer becomes harder.As can be noted as an external sign of that hardening, the applied layer may be lighter or grayer.Keep in mind that the first higher quality than their "greyish" counterparts.

On the other hand, declared as a water-resistant, coating based on only gypsum can hardly be considered as such in full.Indeed, as already mentioned, full resistance to water is provided by compositions based on Portland cement.Very often, water-resistant putty called façade.

This is untrue.Despite some inaccuracy in the title reflects the essence of the application.While these fillers are widely used and for interior surfaces of premises with high humidity regimes.

behavior-based water-resistant putty - how to deal with it?

Generally, any filler for wet rooms or exterior coating hardens within days.Qualitative facade compositions are characterized by high flexibility and the ability to cover the surface of the flat layer, adhesion with harboring basis.

Included in the filler required additional plasticizing components - not only additive to the cement base.The presence of the inclusion pigment dyes allows to obtain high-quality color layer on its entire thickness.Such compositions are often applied on the facades.

However, they have successfully handled not only the facade, but also the internal surfaces intended for painting or other finishing.That front part is used as a finishing coat for wet areas.

feature of most compounds is that for the application does not need any special tools.Different formulations are applied at the appropriate primer layer applied in the usual way.Then facade putty is working on sealing of all defects and irregularities, the so-called stage of leveling spackling.

Perhaps for critical areas will need another layer of moisture-resistant primer composition accordingly.After drying it is already in use exterior plaster, also to be applied with a spatula or metal ruler, depending on the preferences of the masters.Of course, the work is carried out in a dry mode of operation of premises, excluding the impact of moisture.
