Glue paint: composition, varieties, advantages and disadvantages

In the modern market of paints and varnishes there are a huge number of different paints: acrylic, silicate, water-dispersion, which are widely known to the consumer. Glue-based paint stands out in a separate category and is not particularly popular so far.

various shades of adhesive paint

Composition

B 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 number of thickeners, fillers, stabilizing components, dispersing agents and water repellents.

The film-forming part includes: glue, polyvinyl alcohol, starch, carboxymethyl cellulose, polysaccharide, resinous secretions of plants.

Types of adhesive

The adhesive component of the paint may be:

  1. Casein glue - consists of protein components. Such paints are used for finishing facades and interior substrates. They are extremely durable and come in a wide variety of color options.
  2. Dextrinated - based on bone glue. Such paints, as a rule, paint the surfaces inside buildings, since they are not waterproof.

In their appearance, adhesive paints are matte and glossy. The latter contains mica, which allows the painted surface to beautifully shimmer.

Of the varieties, the following can be distinguished:

  • Water-based adhesive paint - this paint quite popular and in demand. It is environmentally friendly, durable, a vapor-permeable surface is created under it. This paint dries quickly and is practically odorless.
  • Silicate - is an extremely resistant type of adhesive. Its main advantage is water resistance, which makes it possible to paint the wettest surface with such a composition.
  • Oil-glue paint - such a paint contains drying oil. It dries long enough - about 48 hours. As a rule, it is used when painting external surfaces.

Benefits

Like all building materials, the paint has both positive and negative properties. Consider the advantages of the material:

  • The indisputable advantage of adhesive paints is the ability to apply them on wet surfaces.
  • The resulting decorative layer has excellent vapor permeability, that is, good air exchange and evaporation of excess moisture.
  • The active ingredients added to the adhesive increase the insulating characteristics of the adhesive.
  • The adhesive paint is very easy to apply, since it is flexible.
  • If you apply the paint correctly, it will serve for quite a long time - 15–20 years. The pigment will not lose its brightness, which is 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.
  • If the required volume was exceeded during the preparation of the composition, then it can be left for some time and it will not lose its quality. 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.

Disadvantages

Glue paints, like all other formulations, have their own disadvantages:

  • The biggest disadvantage is the low resistance to moisture and carbon dioxide. At high humidity, the color characteristics of the paint are lost, since the binder rapidly decomposes. Also, with constant humidity, molds form and various microorganisms multiply.
  • When using this paint, it is important to observe the proportions: excess pigment is fraught with chalking the surface; excess bonding makes the surface uneven and heterogeneous.

Paint the ceiling and walls with adhesive paint

The ceiling is coated with the composition immediately after the primer, when tightly closed doors and windows. Work needs to be done quickly so that after painting it remains wet. The ceiling is painted twice with brushes.

To prevent the flowing paint from interfering with the work, you can put on the brush handle an old cut rubber ball.

You can also paint the ceiling with a spray gun, garden sprayer or a spray 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 needs to be painted from top to bottom. The paint is applied on the surface warm, then it is better off the brush. So that the adhesive paint for the walls does not peel off, one place must be done no more than two times.

water-based adhesive paint

Recommendations for the preparation of adhesive paint

All work begins with the preparation of the paint.

The protein-based paint is prepared as follows: pour the dry mixture with a certain amount of water (the proportions can be found in the instructions). Water temperature should not be lower than 60 degrees. After this, the mixture is stirred and left for 1-1.5 hours so that all components are dissolved. Then you need to add water to the composition.

The paint based on bone glue is even easier to prepare: the dry part and water are mixed in a 1: 1 ratio, the mixture is kept for about 5 hours and applied to the surface.

oil-glue paint

If you observe the preparation technology and the operating conditions of the surfaces, then the surface painted with adhesive paint will differ in saturated color and a silky matte texture, will add gloss to the base and luxury. And the environmental friendliness and durability of such a paint makes it a great option for a living room.
