Work With Primers

Do I need to be primed between layers of putty?

Properly perform the putty work - this means to execute this process taking into account all the subtleties. Any roughness of surfaces: dents, mounds, potholes require special attention. Violation of technology management in the future will affect the quality, and will cost extra money and spoiled nerves.

Advice on how to properly fill surfaces is sufficient. The most controversy surrounding the rules of priming and the need to apply soil before each new layer of putty.

Kinds and features of

fillers. With the help of putty, it is possible to eliminate irregularities and flaws that occur from 5 to 12 cm. These building materials differ from plasters in their composition: they do not contain those substances that allow the filling of large potholes, they are suitable only for levelingminor shortcomings and flaws.

Surfaces after applying putties are smooth and smooth, and minor flaws must be eliminated, using sandpaper for grinding the surface.

Putties are made on the basis of:

  • glue and chalk( gypsum, cement) - they are sold as dry mixes, which require water before use;
  • polymer fillers( these materials are more resistant to moisture) - are diluted with water two times: the first time for swelling, the second to bring to the desired consistency.

In addition, putties are finish and leveling( putty the first layer).The first two layers of putty are designed for rough work, this layer aligns all the irregularities. Manufacturers of this type of building materials put before their products the task, which consists in the possibility of applying it in several layers.

It is necessary that with this method of work, the surface of the walls and ceiling should not be sprinkled or cracked. Finishing( puttying for painting) is applied last layer on top of all others.

Priming as the basis of all

putty work. The main requirement for the surface to be ground is that it should be smooth, smooth and do not crumble. If you apply a conventional gypsum filler on the previous dry layer, then instead of adhesion, the previous layer of liquid will be absorbed from the second or any other subsequent layer. In this case, the quality of the surface will noticeably decrease. In the future, such a wall or ceiling will necessarily peel and crumble.

Therefore, in the process of work before each new layer, the second and every subsequent, the unpainted surface must be primed:

  1. Between the loose lower layers of plaster and before the putty after them put a primer that has the ability to penetrate deep into the thickness of the deposited materials. Thus, adhesion is provided within the two layers. The primer will not allow you to "slip" in the future and crumble off the putty. In addition, priming mixtures with a special property of deep penetration keep the loose previous layers of plaster.
  2. On the layer of a mildly absorbent putty, it is better to apply a primer on an acrylic base. In case of its absence, a primer of deep penetration is suitable.
  3. For waterproof putties it is better to use soils that are compatible with them. To find out which of the materials will be suitable, you should look at the bank in which the building material was purchased. On the packaging of the putty it will be indicated on what basis it is made.
  4. In some cases it is necessary to apply a primer two times, in order to create a better grip.

Quality control of the

The quality of each applied layer must be checked during operation. If you try to hamper a small piece of the coating, and it will peel off at the same time, it means that putty work has been done poorly and the adhesion between the layers has not been achieved.

To correct the situation, before applying the next leveling or finishing coat, it is necessary to apply a deep penetration primer.

In addition to priming shpaklyuemyh surfaces using factory and home-made mixtures, the masters can advise before each new stage of work, to wet the surface with water once or twice. Thus, the layering of materials is carried out by the method of applying putty "on-wet".

To take advantage of this advice and do putty work in this way, you need to have a lot of professional experience. Beginners in this case, attempting to make finishing work with their own hands, do not take up the task of increased complexity.
