In the construction materials market there are many types of putty for walls and ceiling. Each has its own unique characteristics and scope.
One of the most popular types of such a material is a plow-based putty. In this article, consider the features and characteristics of the composition in more detail.
Polyvinyl acetate is easily mixed with water, and when dried, he forms a film with excellent adhesive properties. Therefore, the PVA-based putty falls on most of the types of material and is universal when performing interior finishing works.
For alignment of walls, putty based on the emulsion of polyvinyl acetate is not suitable, as the mixture forms too thin layer. Basically, such a mixture is used to process walls before painting or bleaching wallpaper. PVA-based spacure can be used as a finish layer. The surface treated with such a composition will differ in a white and smooth structure.
Dry putty is distinguished by a large shelf life, subject to the lack of high humidity in the room. The prepared mixture will be suitable for use for twelve hours.
Store the solution is needed in a closed container, then the putty does not fall and will not cut.
Polyvinyl acetate based fastener Apply for interior walls of walls and ceiling. You can use such a material not only under wallpaper and paint, as well as a facing coating. Finishing material is convenient for its versatility: no need to buy different compositions for each type of surface.
PVA putty fits practically for any materials:
- boat concrete;
- polystyrene foam;
- paints and varnishes;
In addition to standard use, the spacing mixture can be used to make decor elements.
Due to its composition and special characteristics, PVA-based putty is well suited for modeling and making various crafts.
Advantages and disadvantages
Like all other types of putty, a mixture based on PVA has its own distinctive features and advantages. We highlight the main advantages of such a material:
- High grip indicators with different surfaces;
- smooth and smooth surface;
- does not have unpleasant odors;
- Low probability of cracking on the surface, as this type of putty has good elasticity;
- easy to apply;
- environmental friendliness;
- Resistance to the formation and distribution of mold and fungus;
- Perfect white color.
The main disadvantage of such a material is primarily in a limited scope of application. PVA putty can not be used:
- For external work.
- For alignment of walls. In order to avoid detachment and formation of cracks, such material cannot be applied with a thick layer.
- For decorative decoration.
- Under ceramic and tile.
- High humidity facilities.
In the current market for finishing materials, you can find the compositions that are adapted for use under certain conditions. Many manufacturers are ready to offer putty, which can be used in wet rooms.
The properties of moisture resistance material acquires due to the addition of polymer components to the main composition of putty.
We make alone
In the independent manufacture of plow-based putty, there are advantages and disadvantages. Benefits include:
- Saving. All components needed for the manufacture of the mixture are quite accessible and have a low cost. In addition, you do not have to overpay the brand fame.
- Quality of the mix. You can independently change the composition and proportion to improve the technical characteristics of putty.
The main drawback of the self-made mixture lies in the absence of special components that are added to the main production in industrial production to improve its properties. In order to make a PVA-based putty at home, the following components will be required:
- Polyvinyl acetate emulsion;
- any dry finish putty;
PVA glue must be dissolved in water in proportions one to one. To the resulting mixture you need to add glycerin and putty. The solution is stirred until the creamy consistency is obtained.
For the manufacture of finishing putty for wood treatment, chalk and plow glue. The method of manufacture is pretty simple: in chalk gradually pouring plow glue until the pasty mass is obtained. It is important not to forget to carefully stir the solution and break lumps.
If you need to make a basic putty or a mixture to close the cracks in the tree, you need to add to the mixture of PVA and the chalk of small sawdust.
The disadvantage of such a solution is a rather long drying process.
Despite the simple composition and ease in the manufacture of finishing material based on PVA, it is recommended to purchase a finished product. In the conditions of industrial production of putty to the main components, special substances are added, which improve the quality and characteristics of the finished material.
To reduce the likelihood of buying a wipe quality putty, it is worth making a choice in favor of well-known manufacturers, having previously studied reviews about products.
The company is one of the leaders in the Russian market for the production of paints. Also, the company produces a large number of collections of putty mixtures.
Finishing material on the PVA dispersion “CORK-S” is suitable for outdoor and interior decoration. The mixture can also be used for sealing small cracks. The finished mixture is sold in plastic buckets of 3 and 15 kg.
The company “Areal +” manufactures eco-friendly finishing materials from high-quality imported raw materials. The putty PVA company “Area” is intended for internal work and has the following characteristics:
- pure white surface color;
- There is no smell;
- High plasticity performance.
Received finishing material in banks of 1.5 and 3 kg and in bags of 15 kg. You can store a putty in a tightly closed container at a temperature not lower than five degrees Celsius.
Firm “Diol” – a major manufacturer of building and finishing materials. Products of this company is manufactured using imported high quality components.
Diol putty PLA polymer-based PVA is designed to apply finish coating on walls and ceiling. Coating can be applied before pasting wallpaper or painting by any kind of paints. It is worth noting that the PVA putty on Diol has only positive customer feedback.
PVA applied on the basis of PVA needs to pre-treated walls. Stucco or basic putty can be used as the main layer. Finishing work is better at temperatures from 20 to 30 degrees Celsius.
Preparation of the surface begins with the procedure for removing various types of pollution. After cleaning, the base is aligned with cement-based plaster or plaster.
If after the procedure of plastering walls on the surface remains irregularities and defects, it is recommended to apply a base layer of cement-based putter. From how qualitatively preparatory work will be completed, the lightness and the rate of application of the finish layer will depend on.
After the foundation for the finish finish is prepared, it is necessary to carefully clean the base layer from dust and dirt. Dust can be removed using a conventional vacuum cleaner, and to remove dirty stains it is necessary to use a damp cloth or sponge.
To remove bold pollution, you can process the solvent surface. The final stage before applying putty will be the surface treatment of the primer. It allows you to significantly increase the level of adhesion. In addition, this procedure will extend the service life of the coating.
Print the surface is preferably in three layers. Before each subsequent application of the primer, the previous layer must completely dry.
After the base under putty is prepared, you can proceed to apply the finish layer.
For finishing works, the following tools will be required:
- Metal narrow and wide spatula for putty. Used to apply a mixture on the walls. The tool must be absolutely clean.
- Construction pistol. We are necessary for sealing sealant cracks in the surface.
- Construction film and painting tape.
- Mixer construction.
Polyvinyl acetate pretty quickly and deeply penetrates the structure of almost any surface, so the pollution from putty will be hard to remove. In order not to stain the room during the finishing works, the windows, the floor and the doors must be covered with polyethylene film. Film can be fixed on surfaces using painting adhesive tape.
If there are wide and deep cracks on the wall, they must be embedded with the installation glue “Liquid nails” or sealant. First of the crack removes dirt and crumb. After stripping the crack need to expand and patch using a construction gun.
The next step will be the preparation of a solution to application. If you purchased a dry putty, you need to prepare the mixture according to the instructions on the package. If you bought a liquid putty, it is advisable to stir it before applying it with the help of a building mixer.
Put putty to the surface with a wide spatula of metal. Equally distribute the mixture on a wide spiter using a narrow tool. Layers need to be applied on the wall wide movements. Layer thickness should not be less than 0.5 millimeters. The drying time of the surface can be twenty-four hours. Using a polyurethane grater, you can polish the finish putty to get a smoother and smooth surface.
