Just a couple of decades ago, repairs and wall decoration were carried out extremely simply: cracks and cracks were sealed with alabaster mortar, and new ones were glued instead of old wallpaper. The current standards and technologies of repair and finishing work differ significantly, and primarily due to the emergence of various building mixtures. For example, one of these modern materials is finishing putty, which allows you to bring the walls to perfect condition.
New features - great result
To eliminate large defects and uneven walls, plaster is immediately used, which is then covered with a layer of starting putty mixture. But these materials do not allow to achieve the desired smoothness, so the “final word” remains with the finishing coating of the walls. With the help of it, minor defects are eliminated after the starting mixture and the final, so to speak, fine leveling of surfaces. Finishing putty has the smallest size of fractions, due to which it is achievedrequired smoothness. The quality of the walls is especially important in the case of preparing them for painting, since no paint can mask even the slightest bumps. The big plus of the “finish” is the fact that it has a white color and this allows you to use it for finishing materials of any shades and be sure of the final result. Among other things, putty coated with a primer ensures good adhesion of any finishing materials to the wall, and this is a guarantee that after some time the finish will not start to fall off.
Finish putty: reviews and recommendations of experts
There are three criteria for choosing a finishing putty - this is the size of the fractions, the speed of solidification and the type of binder (gypsum, cement, polymer). The main of these criteria is precisely the binding base of the mixture. For example, cement finish putty has excellent water resistance, so it is suitable for use in bathrooms, toilets and kitchens. But the disadvantage of such a material is its tendency to shrink, and therefore it is required to apply it in several layers. But gypsum putty does not shrink at all, however, it does not tolerate temperature extremes and high humidity. The most technologically advanced is the polymer finishing putty. It has high plasticity, therefore it is easily applied to surfaces, making them even. But the disadvantage of this material can be considered its high cost.
Finishing Tools
Before applying the finish layer, the walls must be primed. In the process of work, 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 a bucket and transferred to a wide spatula, which is used to level it over the surface. The angle trowel makes it easy to apply material to corners. The thickness of one layer of the coating should not exceed 2 mm, otherwise it may crack when dried. The consumption of finishing putty per square meter will, of course, depend on the thickness of the layer, but on average it is 1 kg per 1 m22.
