The question of what to plaster the walls in the bathroom, is a very popular and important. What to choose? Plaster, cement composition or universal Rotband? On this topic we have talked to experts.

Sanitizing plaster - basic characteristics

The plaster walls in the bathroomMixtures used in the bathroom should have sanitizers properties. Now the construction market sold a lot of compositions, modified by various additives and plasticizers.

Dry sanitizing mixture is much stronger than ordinary cement-sand mixture, they are easier to apply and faster cure. Walls are ready for laying tiles or plaster for painting in a week.

In the absence or incorrectly made waterproofing and moisture contained therein rise salts from soil and exude on the surface of the wall in the form of "efflorescence". This leads to the gradual destruction, occurrence of a stable moisture and development of microorganisms.

Sanitizing mixture can avoid many problems.

  1. They are well protected from coming out of the foundation and supporting walls moisture and salt all subsequent layers of aligned plaster walls, including facing materials. Prevent the formation of efflorescence on walls.
  2. Remove moisture from the emerging internal structural elements of the room.
  3. Hydrophobic mixture protect the walls, being a good waterproofing layer.
  4. Have a high degree of vapor permeability.
  5. It does not crack during curing and during operation.
  6. Is an environmentally friendly building material.
  7. Have high sulphate resistance.

Such mixtures can not be applied to the base of gypsum and used as a waterproofing protection groundwater foundations, plinths and walls.

Hydrophobic pokryatiya made of two layers. The first of these being the base, has a porous structure, the second layer - sanifying. To protect the surface, sufficient thickness of the solution at 2 cm.

The operating principle of sanitizing mixture:

Moisture from the walls enters the first layer, wherein the salts are retained and remain in its pores, water is removed as it evaporates through the upper layer of vapor permeable. Due to this property furnished on this basis topcoats do not deteriorate.

Applying the mix

Basis weight under sanitize should be strong and free of oil, grease, paint residues. Weak and backward cover portions must be removed and repaired solution.

The seams on the masonry is necessary to embroider, efflorescence - clean with a steel brush. If their area is large, we recommend the use of grinders with a special nozzle in the form of a metal brush.

One day before application of the plaster on the wall with his hands on the wall surface throws obryzg which improves adhesion and a base solution. If the mixture of gypsum, wall mounted plastic reinforcing mesh.

Tip! The dry mixture and shuts only pure water at a temperature of + 15-20 ° C. Composition pour out a little from the packaging into a container with water and poured mix. Density of the solution is selected depending on the desired thickness of the layer, adjust it by adding water.

Before prepare a solution for plaster, it should be borne in mind that the finished mixture must be developed for 15-20 minutes. If this is not done, the porosity and qualitative characteristics of the resulting coating will deteriorate. Therefore, batches make small meals.

Works on masonry joints begin with clogging and nakidyvaniya base layer. The solution can be applied either manually or mechanically in one or several stages, depending on the desired thickness.

Rub plaster walls in the bathroom at a time can be in a layer of 1-3 cm. After spraying, and the resulting surface zaravnivaniya overwritten.

Tip! Damage trim should not be too quick to dry. Therefore, it must be protected from intensive cure for at least 24 hours.

If further improvement is expected on the walls facing covering - tiles or plaster, after grouting the entire surface of the metal brush scratched, thereby increasing the adhesion of the topcoat to the received base. Facing layer recommended not earlier than 28 days after the work.

The use of decorative plasters

At the moment, is becoming more popular application as a finishing coating walls are not ceramic tiles and plaster their own hands.

Preparatory work

Tip! Before starting work, it is recommended to make additional waterproofing surfaces and soak them in a primer.

To increase water repellent properties of the coating as possible and by means of special formulations which are based on natural wax. Very frequently used structural facade mixture which is capable of withstanding high humidity with minimal consequences for themselves.

The use of such materials for the finish cladding has several advantages over traditional ceramic tiles. It is more functional, because in addition to all the advantages of tile is also water vapor permeability and durability.

In addition, you can always repaint in a different color, that will change the interior of the premises without the mess and investment.

Before plaster walls decorative composition, you must consistently perform simple preparation walls.

Surfaces should be cleaned of old coating - paint formulations, tile, wallpaper, ill keep the old finish, wash the dust and dry.

Walls and ceilings are primed in two layers with a special solution to improve coating adhesion to the base surface. Perfectly smooth walls do not require, as a facing material perfectly covers all minor defects.

After the primer is completely dry, you can start plastering.

Strengthening of decorative plaster

Pattern and texture of the plaster can be very different, it all depends on your imagination. At the final stage of the decorative covering is coated with mastic based on natural wax. This will not only increase the water resistance of the walls, but also gives them gloss surface.
