Plastering damp room , moisture penetration protection

for decoration with high humidity, a special material - plaster for damp rooms.Such a coating can increase the level of protection of the walls of basements, rooms, located in the basement of the building and bathrooms.Waterproof plaster is not in vain considered to be a universal tool that requires no special skills to use and large investment funds.

Main plaster property for wet areas - its increased moisture resistance.Used for leveling of walls of brick and cinder block, and for leveling and dressing of plaster, cement surfaces and surfaces of the foam.

There are several methods of applying the plaster, depending on the material used and the surface on which the plaster is applied.You can apply ready-made special blend, to prepare water-resistant plaster alone or treat already plastered surface special water-repellent solution.

Ready kinds of moisture-resistant plaster:

  • manufactured from environmentally friendly components, which enables its use even in spaces for living.It does not contain harmful impurities that allows to apply the plaster in places of high temperature.Such mixtures are not radioactive and harmless;
  • ease of use due to the plasticity of this mixture.In applying plaster no need for any special technical devices, the application is made on the surface of conventional spatulas;
  • have high strength, which will result in a smooth surface without cracks.Ability to add a curing agent before application to the surface of the plaster will give a mixture of resistance to cracking, even in areas that can not be heated for a long time, or in which there are sharp fluctuations in temperature and where the temperature is often much higher than the norm;
  • protection against humidity - allows the use of such a mixture of both in domestic and external decoration works.After drying, wrought plaster forms a waterproofing layer protecting any surface against moisture.

process of preparing moisture-resistant plaster

Prepare a waterproof plaster mixture can be independently, to increase the moisture resistance of the used curing agents that are added to the mixture of sand and cement in the proportions of one to one.You can use lime or other hardeners replacing components.

If you want to protect are already plastered surface, then this will need waterproofing or impregnation mixture.

Before applying the plaster on the surface of interest to us, it is necessary to carry out the preparatory work, which includes: cleaning of walls and surfaces of old paint layers, plaster dust, and most importantly, that has already been or may appear during the repair work.This is done for better adhesion of the applied layer of plaster with a water-repellent surface to be treated.Therefore, the better the cleaning made of extra spots of paint and plaster, the better and smoother new layer will form.

What to do with the surface on which the whitewash was applied?It is hoped that the plaster will fall on good lime surface, but the necessary adhesion of the new layer is unlikely to reach the old whitewash.Therefore, this layer is also better to clean off or wash off.Possible to use special impregnation which is also intended for the treatment of concrete surfaces.We should not forget that the impregnation is applied several times, with pauses of about half an hour.Complete drying of such impregnation will happen in ten hours.Time to dry rough - should take into account the ambient temperature, and the manufacturer's instructions.

mixture for plastering of the walls is necessary to mix well, regardless of whether you use a ready-made or prepared on their own.In such a mixture should be no lumps nerastvorёnnyh - this depends on the quality of the work performed.Poor Stir the mixture begins to rapidly crack, waterproofing effect is broken.

During the plaster should take into account the temperature regime.Such mixtures should use at a temperature of not less than five and not more than thirty degrees.Violation technology using such plasters can lead to delamination and its subsequent alteration of the work performed.

The process of the plaster is produced in several stages:

  • the prepared surface sprinkles movements applied base layer of plaster;
  • after a certain time (usually quite three hours) is applied leveling layer;
  • after drying (five to six hours), the final grout surface.

final stage - the application of wax, if you use decorative plaster, or wallpapering.In any case, the use of plaster for wet surfaces - an affordable way to sealing the premises.Read also how to seal the mounting foam.
