What should be the surface for applying plaster with your hands? preparatory work technology is not too different from the preparation walls for painting and wallpapering. However, it is not necessary to be zealous, too - decorative mixture due to its plasticity perfectly hides all the small defects.

So perfectly smooth wall we do not need, but still have to work on the elimination of major irregularities.

Note! If the room in which you plan to finish walls, characterized by elevated levels of humidity along with the primer should be treated with an antifungal composition of the wall.

Elimination of cracks

  • The discovered cracks embroidered with an angle grinder with diamond disc. Embroidered and cleaned repair cracks fill composition. If the cracks are deep enough and volume, repair the product is applied in several stages.

If you plan to a method for applying decorative plaster sufficiently thick, which has a distinct texture type, filler surface is not obligatory.

Otherwise defects tread base through the inlay, and the decoration layer flow will be considerably greater. And it can be quite painful blow to your pocket!

plastering

  • Once a layer of putty is applied and dried, the dirt acrylic cover it. The optimum is the use of deep penetration primer, it provides the best adhesion layers.

  • After filling is completed, the grind surface. The best result gives the hand sanding with fine sandpaper.

Recommended for decorative finishing layer is laid a special primer.

Primers mixture under the decorative plaster is applied, taking into account the following points:

Trial plastering

Trial plastering

Before you start plastering the walls with his own hands, it is recommended to conduct a trial process: select a location on the wall near one of the corners and cover it with plaster. So you will see the actual texture of the new decorative coating and its hue.

If you plan to combine on the same wall both options, then to create a smooth transition between the lines smooth and textured applying, you can use masking tape. Apply a smooth plaster (taping tape will help you not to climb on the "texture" part), and then protecting the area already plastered the same tape, apply textured plaster.
