Types of decorative plaster: characteristics and master classes for applying to the walls of the house

With decorative plaster, it is easy and simple to create expressive and unique patterns on the surface of the walls. Admiring the spectacular facade, we can conclude that only specialists can perform such a task. However, it is not. The main role in creating original reliefs is played not by the skill of a specialist, but by the material he uses: decorative plaster.

What are decorative plasters

The composition of decorative plaster mixes is different from the composition of the usual not only the presence of filler. If the material is intended for facade (external) work, it also includes additional components that provide an increased resistance of the facing surface to moisture, temperature extremes, and ultraviolet light.

Design effects that can be obtained using special decorative plastering techniques:

    Embossed plaster

There are three types of decorative plasters:

  • mineral;
  • textured;
  • structural.

They all have their own characteristics, both in terms of composition and application rules.

Mineral decorative plaster

Mineral decorative plaster

The base of mineral plasters is natural ..

. Crumbs and dust of various valuable kinds of stone are used as a filler: granite, marble, onyx, malachite. Included are quartz sand of various grain sizes. Cement and gypsum act as a binder. Cement-based plasters are classified as facade.

Mixes with a gypsum binder are used exclusively for interior work.

Add dry components to a container with water

The ready-made mixture can be applied to the wall in several layers.The final stage of work is waxing or painting. The wax serves as a protective and decorative coating.

Application of facade plaster

Since all types of mineral plasters are diluted with water, they do not have a long "life" of the mix. Therefore, it is recommended that you prepare just enough mixture so that it can be worked out before it starts to solidify.

One of the advantages of mineral dry plasters is that they have a much lower price than ready-to-use acrylics.

Textured plaster

Finishing the facade with textured plaster

Textured plasters are pasty mixtures that can be tinted in any color during the mixing process, or coated with paint after the finishing layer has been applied and hardened. This type of plaster is distinguished by its unsurpassed plasticity, which allows you to create real masterpieces on the walls.

Acrylic textured plaster

This effect is provided due to the natural fibers included in the mixture, which can be cotton, linen, wood ..

. Some manufacturers use ground brick as filler. With the help of mixtures of this type, you can create relief paintings, bas-reliefs and panels.

Decorative facade plaster

Popular "Venetian" plaster is not a separate type of decorative plasters, but belongs to the category of textured mixtures. It is called "Venetian" because of its special composition, which allows the use of a special application technique, which provides a spectacular wall pattern.

Structural plasters

Plasters of this type are heterogeneous granular masses. Potassium silicate (silicate plasters), synthetic latex (latex plasters), cement-lime composition act as a binder. There are two types of structural renders:

  • water-based;
  • solvent-based.

Hence the classification of these mixtures: water-borne and solvent-borne. The main representatives of this type of finishing mixtures are "Bark beetle" and "Fur coat".

Precisely they are most often used in facade decoration. The reason is simple: these mixtures are easy to apply, form an attractive surface pattern, and have excellent wear resistance. In addition, they have one more advantage: a reasonable price.

For dilution of solvent-borne mixtures, White Spirit is predominantly used. It should be noted that it does not dissolve anything in the plaster mass.

He precisely dilutes it to the desired consistency. Therefore, experts call any liquid added to the finishing composition not "solvent", but "diluent".

Acrylic plaster

Pebbled plaster "Ceresit"

Acrylic plaster is the most popular among structural mixtures. Its distinctive feature is that it is ready for use immediately after purchase. These mixtures do not need to be diluted with water or solvent.

This fact is their undoubted advantage. In addition, acrylic plasters are significantly more elastic and durable.

They have higher adhesion (adhesion to the substrate) than mineral and solvent based structural ones. Acrylic can be applied to almost any surface: wood, brick, concrete, aluminum.

In sealed packaging, acrylic plasters retain their properties from 6 months to 1.

5 years. Some manufacturers produce mixtures with a shelf life of up to 2 years. Another advantage of acrylic compounds is that the walls treated with them can be painted.

Decorative plaster application techniques

Mineral plasters must be prepared for use by diluting with water.

On average, up to 30% of the liquid is required. All manufacturers indicate the required proportions on the product packaging. Mineral mixtures are applied in two layers.

The use of any plaster compound requires careful surface preparation. The walls should be inspected for deep cracks, making sure that the bearing surface is strong enough and does not require major repairs.

Preparation of walls for plaster

The next stage of work is priming. To accomplish this task, deep penetration primers are used, intended for external finishing work.

Primer application

Plastering of the facade starts from the corner of the building. The work is carried out in stages, gradually applying the mixture to areas of a small area. The first layer is base.

It is applied with a trowel so as to avoid overlaps and to obtain the most even surface possible. For leveling, you can use a wide-blade trowel or a rule.

Roller

Roller for decorative plaster

Depending on the material of which the roller is composed, there are several types of rollers:

  • wooden;
  • rubber;
  • plastic;
  • leather;
  • nap.

Standard sizes:

  • with roller width up to 30 cm (short rollers);
  • with roller width up to 50 cm (medium length);
  • with roller width from 50 cm (long rollers).

It is conditionally possible to divide all types of rollers into textured and structural. The latter have a more relief surface than the former. Textured ones are designed to create imitations like marble, natural stone, textiles.

Plasters "Bark beetle" and "Fur coat" are applied with textured rollers.

Structural rollers are designed to produce a pronounced relief pattern, consisting of a repeating rather complex pattern. Outwardly, it creates the effect of volumetric wallpaper. The decorating technique with these tools is more complex than with textured rollers.

Types of decorative plaster: characteristics and master classes for applying to the walls of the house

Types of rollers

Working with structural ones requires utmost care and attention.

The rollers of these tools are usually made of wood or plastic. The use of such rollers requires compliance with several rules.

  1. Surface decoration is performed according to the base, already solidified and leveled layer. For application, use a liquid batch. If you work with a dense composition, the grooves of the relief texture of the nozzle will quickly fill with the mixture, so you will not be able to get a pronounced pattern.

  2. The pattern is applied in stripes by rolling the roller in the direction from bottom to top or top to bottom.
  3. Each next strip should fit snugly to the previous one, but not overlap it.
  4. When decorating walls, try to avoid pressure on the roller. In this case, the relief of the picture will be of the same depth.
  5. During operation, the wall surface is moistened using a spray gun or a paint brush.

  6. The roller is periodically dipped into a container with water, washing off the adhered plaster mixture from it.
