How to choose a filler: tips for choosing
Plastering the walls is an integral part of any renovation. The application of a putty layer prepares the wall surface for further work. The material fills small cracks and smooths out surface defects before painting, decorative finishing, wallpapering.
Today manufacturers offer a wide range of putties to work with various surfaces. You can choose the best option depending on the material of the walls and ceiling. For internal and external work, a different composition is required. In this article we will answer the question: “the better to putty the walls”, we will tell you about the compositions and their features.
Types and purpose
Manufacturers produce several types of putty:
1. Start, which is used for leveling the surface;
2. Finish;
3. Universal
Starting. Differs in coarse grain size, strength and high degree of adhesion.
Finish. Used after the start. It acts as a facing material before painting or wallpapering. Creates a smoother surface due to less grain.
Universal is an alternative to finishing and starting putty.
Assortment of putty by composition
1. Cement-based. Possesses moisture resistance, resistance to temperature fluctuations and a loyal price.
2. On a plaster base. The plaster does not shrink, dries quickly and does not support combustion, protects the wall from the formation of fungus, improves thermal insulation, and has an affordable cost.
3. Polymer. Contains polymers, thanks to which an impeccable result is achieved when working with metal, plasterboard, brick, concrete surfaces. These include acrylic, latex, vinyl putties and polycement. The most frequently asked question is: "What kind of filler to choose for the ceiling?" The store will advise you to give preference to polymer compounds. They have a high degree of adhesion, do not emit odor, and are not afraid of moisture.
4. Oil and glue. Ideal for wood and concrete surfaces;
5. Putty on the basis of PVA is used for leveling surfaces made of concrete, asbestos, drywall. The composition is enriched with antiseptic components that prevent the development of mold.
Which putty is better
The putty is selected depending on the chosen finish.
• When preparing walls and ceilings for painting or thin-layer decorative plaster, use a polymer finishing putty, produced in the form of a paste. Only such a composition will make it possible to create a perfectly smooth surface. In case the budget does not allow using this material on the entire surface, treat the ceilings with finishing paste, and the walls with gypsum finishing putty.
• When preparing walls for wallpaper or a textured decorative finish, the best choice would be a gypsum finishing putty: it will hide all the irregularities and differences, and will not hit the budget hard.
• For filling drywall joints, use polymer putty in combination with special reinforcing tapes - then the joints will not crack and retain their aesthetic appearance for many years.
• When preparing facades for finishing, use cement or cement-polymer material. But when preparing for painting external slopes, it is better to take a polymer finishing paste.
