All paints should contain the following components: pigment – a substance that gives color, a base that binds all the ingredients and forms a surface film, fillers that give the paint strength and shine, additives that allow it to quickly dry and harden (siccatives), protect the wood from mold fungus (fungicides), fire retardant foam.
Enamels for indoor work are not resistant to the effects of natural phenomena, so they are not used in the coloring of facades. For works inside the room most often use the following varieties of paints: acrylic, alkyd, water-dispersion, polyurethane. Acrylic paints for wood based on acrylic are very profitable, from a commercial point of view, compositions.
Among their positive qualities we should mention:
- Cheap. The cheapest of all kinds of polymers with equal working qualities.
- Practicality. Carry the action of sunlight, as well as temperature fluctuations.
Annuity – 3 years. Rapidity of drying. Mechanical firmness. Acrylic paint creates a dense, elastic coating, resistant to various influences. Water resistance. The tree under the acrylic does not rot or collapse. Resistant to changes in temperature. The possibility of coloring in any desired color. Acrylic based wood paint Painted surfaces do not fade in the sun. The chemical composition of acrylic polymers is constantly being improved. Manufacturers are working to reduce the cost of such paints, but their quality remains at a high level. The quality characteristics of acrylic water-dispersion paints are determined by the level of whiteness and concealment. The high whiteness level captures the purity of titanium dioxide used as a pigment.
The ability to hide a plane treated with such enamel with a small number of layers is called concealment. This parameter determines the cost of the paint and depends directly on the pigment that is contained in it, showing its density and density. The contents of the can should not be too liquid (a can of 10 litres weighs 15 kg). Important! When buying the product, make sure that the enamel is designed specifically for wood. Alkyd enamels, unlike acrylic enamels, alkyd enamels consist of the same name varnish, which is a solution of thick resin with the addition of rosin, glycerol and vegetable oils.
Additional components that can improve any properties can be included in the paint, then everything is mixed with the solvent. Alkyd enamel for wood Alkyd enamel dries 2-3 days, does not lose its color, durable. Such compositions are also suitable for street work. In addition, they have a number of advantages: water resistance; durability; low price; protection of wooden surfaces from rotting; resistance to mechanical impact. Due to their properties, alkyd enamel is ideal paint for wood.
Tip! The variety of such paints in stores is huge, so take your time buying the first one you get, study everything thoroughly on the spot. Water-dispersion In the role of diluent of such paints is water, so they are considered environmentally friendly and non-combustible. The binding polymers here can be oil or resin. The term “dispersion” refers to the mechanical suspension of solid elements in a liquid. Aqueous dispersion paints are produced as a liquid paste. Immediately before starting work, they are diluted with water to the required consistency.
