Just a couple of decades ago, repair and decoration of walls was carried out very simply: cracks and cracks were covered with alabaster mortar, and new ones were glued instead of old wallpapers. The current standards and technologies for repair and decoration work are significantly different, and primarily due to the appearance of various building mixtures. For example, one of such modern materials is finishing putty, which allows you to bring the walls to perfect condition.
New features - great result!
To eliminate major defects and irregularities of the walls, plaster is immediately used, which is then covered with a layer of the starting putty mixture. But these materials do not allow to achieve the desired smoothness, so the "last word" remains with the finish coating of the walls. With it, the elimination of minor defects after the starting mixture and the final, so to speak, fine leveling of the surfaces is carried out. Finishing putty has the smallest size of fractions, due to which the required smoothness is achieved. The quality of the walls is especially important when preparing them for painting, since no paint can mask even the slightest bumps. A big plus of the “finish” is that it has a white color and this allows you to use it for finishing materials of any shades and to be sure of the final result. Among other things, a putty coated with primer provides good adhesion of any finishing materials to the wall, and this is a guarantee that after some time the finish will not fall off.
Finishing putty: reviews and recommendations of specialists
There are three criteria for choosing a finishing putty - the size of the fractions, the pour point and the type of binder component (gypsum, cement, polymer). The main of these criteria is precisely the binder base of the mixture. For example, cement finish putty has excellent water resistance, therefore it is suitable for use in bathrooms, bathrooms and in kitchens. But the disadvantage of this material is its tendency to shrink, in connection with which it is required to be applied in several layers. But the gypsum putty does not shrink at all, but it does not tolerate temperature extremes and high humidity. The most technologically advanced is the polymer finish putty. It has high ductility, so it is easy to apply on the surface, making them even. But the disadvantage of this material can be considered its high cost.
Tools for applying "finish"
Before applying the finish layer, the walls must be primed. In the process, three spatulas will be required: narrow (10-15 cm), wide (40-60 cm) and angular. With a small spatula, the finished mixture is collected from the bucket and transferred to a wide spatula, which is used to level it on the surface. Corner spatula makes it easy to apply material to corners. The thickness of one coating layer should not exceed 2 mm, otherwise it may crack if it dries. Finishing putty consumption per square meter will, of course, depend on the thickness of the layer, but on average it is 1 kg per 1 m 2 .
