In the modern market of paints and varnishes there is a huge number of different paints: acrylic, silicate, water-dispersion, which are widely known to the consumer. Adhesive-based paint stands out in a separate category and is not yet particularly popular.
Composition
The composition of the adhesive paint includes inorganic pigment grains and organic, as well as film-forming components, which can be synthetic, animal or vegetable. In addition, the composition contains a small amount of thickeners, fillers, stabilizing components, dispersing agents and water repellents.
The composition of the film-forming part includes: glue, polyvinyl alcohol, starch, carboxymethylcellulose, polysaccharide, resinous plant secretions.
Types of adhesive composition
The adhesive component of the paint can be:
- Casein glue - consists of protein components. Such paints are used for finishing facades and interior bases. They are extremely durable and come in a variety of colors.options.
- Dextrinated - made on the basis of bone glue. These paints are usually used to paint surfaces inside buildings, as they are not waterproof.
According to their appearance, adhesive paints are matte and glossy. The composition of the latter includes mica, which allows the painted surface to shimmer beautifully.
From the varieties, the following can be distinguished:
- Aqueous emulsion adhesive paint - this paint is quite popular and in demand. It is environmentally friendly, durable, a vapor-permeable surface is created under it. This paint dries quickly and is virtually odorless.
- Silicate is a super-resistant type of glue paint. Its main advantage is water resistance, which allows it to be painted with this composition on the wettest surface.
- Oil-glue paint - this paint contains drying oil. It dries for a long time - about 48 hours. Typically used when painting exterior surfaces.
Benefits
Like all building materials, paint has both positive and negative properties. Consider the pros of the material:
- The indisputable advantage of adhesive paints is the ability to apply them to wet surfaces.
- The resulting decorative layer has impeccable vapor permeability, that is, good air exchange and evaporation of excess moisture.
- Active ingredients added to the adhesive increase the insulating properties of the adhesive.
- Gluethe paint is very easy to apply as it is flexible.
- If the paint is applied correctly, it will last quite a long time - 15-20 years. The pigment will not lose its brightness, hence another plus - durability.
- The matte texture of the paint allows you to get a perfectly smooth surface and a deep shade.
- Glue paint is considered highly environmentally friendly, due to the absence of harmful chemical compounds and toxic substances in the composition.
- If the required volume was exceeded during the preparation of the composition, then it can be left for a while, and it will not lose its qualities. To preserve the paint, you need to ensure a constant temperature and humidity in the room, and store the prepared composition in a clean, dry container.
Flaws
Adhesive paints, like all other compounds, have their drawbacks:
- The biggest disadvantage is the low resistance to moisture and carbon dioxide. At high humidity, the color characteristics of the paint are lost, as the binder rapidly decomposes. Also, with constant humidity, mold fungi form and various microorganisms multiply.
- When using this paint, it is important to observe the proportions: an excess of pigment is fraught with chalking of the surface; excess binder makes the surface uneven and uneven.
Painting the ceiling and walls with adhesive paint
The ceiling is covered with the composition immediately after the primer, with doors and windows tightly closed. Work must be done quickly toafter painting it remained wet. The ceiling is painted twice with brushes.
To prevent dripping paint from interfering with work, you can put an old cut rubber ball on the handle of the brush.
You can also paint the ceiling with a spray gun, a garden sprayer or a spray gun from a vacuum cleaner. The coating applied in this way has a smoother surface.
Walls can be painted as soon as the ceiling is completely dry. The wall must be painted from top to bottom. The paint is applied to the surface warm, then it comes off the brush better. To prevent the adhesive paint for the walls from peeling off, one place should be carried out no more than twice.
Recommendations for the preparation of glue paint
All work begins with the preparation of paint.
Protein-based paint is prepared as follows: a dry mixture is poured with a certain amount of water (proportions can be found in the instructions). The water temperature must be at least 60 degrees. After that, the mixture is stirred and left for 1–1.5 hours so that all components dissolve. Then you need to add water to the composition.
Bone glue-based paint is even easier to prepare: dry part and water are mixed in a 1:1 ratio, the mixture is kept for about 5 hours and applied to the surface.
If you follow the technology of preparation and operating conditions of surfaces, then the surface painted with glue paint will differ in rich color and silky matte texture,will add gloss and luxury to the base. And the environmental friendliness and durability of this paint make it a great option for a living space.
