Plastered of walls and ceilings is carried out in several stages: first apply a base coat, primer, then apply the final coat, sometimes by double Shpatlevanie.The upper layer of finish are presented the most important requirements: it must be exactly the previous ones, as well as resistant to external influences.Furthermore, the finish coat does not comprise filler materials with fractions greater than 0.5 mm.

Why finish plaster walls

Fillers are used to align the walls inside and outside the premises.Prepared over

The finish coat is applied on top of the previous layer , and must be perfectly flat

The finish coat is applied on top of the previous layer, and must be perfectly flat

of used as the basis for other materials, such as a wallpaper or painting.The final coat is the finishing, so it is important to have a smooth surface.

The desired properties are provided by fine grindi

ng of the components of the material.Has the best quality of finishing putty, a filler made from fines of up to 0.15 mm when applied to the surface of the wall, it can not be sanded.The chemical composition of filler to finishing work practically does not differ from the materials for basic and intermediate shpatlevanija, the only difference is in the amount of material fractions.

Choice fillings

All kinds of fillers, depending on the production of material, divided into three groups:

  • plaster - with its use of the finish plaster walls is performed in a low-humidity environments.Plaster - it is not water-resistant material, in bathrooms, shower rooms, kitchen and bathrooms finish based on it quickly will become worthless.Advantages of plaster filler - no shrinkage and increased the speed of drying;
  • cement - suitable for processing rooms with high humidity.It has high resistance to water, has a low shrinkage during solidification;
  • acrylic;
  • polymer - option for rooms with normal humidity.Good and quickly dries up, held firmly to the wall surface.The minimum thickness of the finishing layer is only 0.2 mm.Prepared on the basis of polymers putties have only one drawback - a very high price.

second important component putties - lime.It is important to match the size of its size fractions bases factions, otherwise the mixture will turn out poor quality.

for self-repair facilities best suited polymer filler.It has a high viscosity and has good adhesion, thereby finishing puttying walls will perform at the first attempt, even without possessing the necessary expertise.

Technology applying the finishing putty

Application finishing putty is carried out only over the starting or intermediate finishes.The upper layer material should have a thickness of not more than 3.1 mm, and, the thinner it is, the better.Start to work only after days after the previous layer material was applied.

Before you apply the finish plaster is required to prepare tools - large and small spatula.The first is suitable for the finishing of wide surfaces, and the second - for the hard to reach places.Putty is applied sweeping movements, spatula firmly pressed against the wall surface.The direction of motion spatula should not coincide with the direction, which was selected for the previous layer.For each treatment portion is carried out several times a tool to a layer of material turned perfectly smooth.

There is another application technique which is that first putty is applied to the wall with short strokes in a single layer.When it dries, apply control layer.

stages and the order of work

The first stage - preparatory.Dry putty mixture is diluted with water to obtain a solution of desired consistency.To perform this work, using a special container of suitable size, first it is poured into cold tap water and then added to the powder proportion as indicated on the package.The mixture was stirred using a mixer.

When rotating mixer blades will strike the side of the container, and before you apply the finish plaster on the wall, the solution may show dirt particles that are there because of the fall.To avoid this, it is recommended to thoroughly wash utensils before preparing the fillings.Also, do not use metal containers, because they may rust and scale bits will mixture.The best option - clean plastic utensils.

If you do not have time to prepare the material, can be purchased already liquefy the mixture into the hardware store.It costs about 20% more expensive than dry powder.Details how to choose a ready-made plaster.

next step - directly applying putty on the wall surface.To properly carry out this work, it is recommended to get acquainted with the educational video.In the commercials shown on concrete examples, what the finish coat, and how to use it correctly.

Putty, which has in its composition of compounds with a fraction of more than 0.15 mm, after drying grout needs.Typically, this is used sandpaper grit 150. As a result, the processing will be eliminated minor defects which spoil the texture and appearance of the surface.If the selected repair putty material fractions consisting of less than 0.15 mm, additional finishing is likely not required: this plastic material forms a homogenous mixture, which upon drying forms a virtually defect.
