Acrylic putty is a fairly common product in the modern construction market. It is one of the varieties of polymer finishing materials.
Main characteristics
The main distinguishing feature of acrylic compositions for puttying walls and ceilings is the fact that they are presented for sale in the form of a finished mass, which does not require mixing with water or mixing with other ingredients. The main component of the described mixture is acrylic, which is a synthetic substance with modified properties. It perfectly interacts with the rest of the components, as a result, the mass acquires uniformity, and after the completion of the drying stage forms a dense and smooth surface with a perfectly even texture.
If you use this putty, you can be sure that it will not become cracked or crumble after drying. Having familiarized yourself with the assortment of such mixtures, you can understand that they are presented by the manufacturer in several varieties. For example, a facade is best suited for finishing exterior walls, as well as floors inside the house. As for the water-dispersion mixture, it is great for finishing concrete walls, as well as eliminating defects on wooden surfaces. Acrylic putty can have a different composition, which determines whether the mixture will be used to create a starting or finishing layer. In the first case, the master has the opportunity to create a draft coating to mask cracks, level drops and recesses. A finishing putty is used to decorate the finish.
Differences in acrylic putty on the type of base
Acrylic putty may vary in the type of material on which it must be applied. For example, woodwork compounds can even be used on drywall surfaces. There are also those compounds that are designed for finishing brick, metal and concrete substrates. If you want to save money, it is best to purchase a universal material that can be used to process external and internal walls.
Key Features
Acrylic putty has certain characteristics, among them plasticity, water-repellent ability, ease of application and short drying time should be highlighted. Due to the plasticity, you will be able to create a coating that is not afraid of temperature changes, shock loads, as well as prolonged exposure to frost or heat. Thus, the described compositions do not crumble and are not covered by cracks.
Thanks to the water-repellent properties, the walls gain excellent protection against decay, mold and dampness. An additional advantage is the ease of working with a similar composition, which can be applied to any surface using a spatula. If it is necessary to cover the wall with as thin a layer as possible, a solvent should be added to the ingredients, pouring the resulting composition into an airbrush. Putty for painting can also be used by you, while it will manifest all its best characteristics, for example, it will dry within the shortest time after application. That is why it is necessary to try to work with the mixture as quickly as possible, since it will harden in the tank within an hour. The surface of the already frozen putty can be sanded using sandpaper. As a result, it will be possible to obtain a coating that allows the walls to breathe, eliminating the occurrence of fungus and mold.
For reference
Putty for painting is able to provide the walls with improved thermal insulation qualities, after drying, the composition will not burn, which indicates its safety in case of fire. These mixtures can be used safely inside homes, as they are environmentally friendly and do not emit harmful substances into the environment.
Negative characteristics
If you decide that you will use putty for wall or ceiling decoration, the price of this material should interest you. Cost, by the way, is one of the minuses of this composition. So, for a universal mixture you have to pay 740 rubles. In this case, we are talking about a Russian-made product, while foreign analogues will have to pay even more. Another negative quality is the need for thorough grinding after the completion of the drying phase. This can be very time-consuming and problematic for a master who does not have enough experience. During this, a large amount of fine dust will be released, which can harm the human respiratory system and will lead to the need for a long and thorough cleaning.
Putty application
For even bases, a spatula of a sufficiently large size can be used, while for corners and inaccessible places a smaller tool is suitable. Initially, a starting layer is applied, the thickness of which is 6 millimeters. If the base is in poor condition, crumbles and is covered with cracks, then the first layer should be reinforced with a special mesh, it is best that it is plastic. After the first layer has dried, which will take about a day, you can start applying the second. Often, about 3 layers are required for walls or ceilings. Puttying with a top coat should be done so that the thickness is 2 millimeters. When working on each layer, you need to change the direction of movement of the spatula, this will allow you to form a more uniform coating. After the wall should be treated with sandpaper, the most commonly used size is 150 sandpaper.
What putty to choose
If you have chosen putty for repair work, the price is not the only thing that should interest you. It is important to pay attention also to the manufacturer. The most popular brand today is Vetonit, which can be used as the basis for wallpaper. In open form, the surface will dust, which is not suitable for residential premises. The mixture has a low cost, as well as low consumption, which varies within 1.2 kilograms per square meter. If there is a need to close up errors in the form of holes and seams on drywall, then you can prefer the equally popular Knauf putty, which can act as a base not only for wallpaper, but also for painting. Its consumption is slightly higher and amounts to 1.7 kilograms per square meter.
Considering the best putties, you can also pay attention to Eunice, which is a composition of increased whiteness. It can be used for dry heated residential buildings. If you want to use it for finishing, the basis may be a mixture of Vetonit or Knauf. For damp rooms, basements and external walls, you can use "Prospectors", which is not used for decorative painting, as it is the heaviest lining.
Which putty for wallpaper is suitable, was described above, but quite often during repair work there is a need to process more complex surfaces, for example, those that are found in damp basements. The Hercules mixture has high adhesion and allows you to close potholes and cracks in concrete.
Conclusion
Regardless of the quality of the putty, it is important to properly prepare the walls, even if they are used in ideal conditions in terms of temperature and humidity. Which putty is better, you can understand for yourself by reading the information presented above. But even having bought the highest quality composition, it is important to rid the walls and ceiling of the old plaster, paint and wallpaper, only then you can achieve a positive result.
