Latex paints represent emulsions containing polymer particles that are not dissolved in water, which, after evaporation of the water, turn into sealed plastic film. The surfaces painted with this type of paint are characterised by noteworthy flatness and smoothness. These paints are mainly utilised for painting the ceiling and walls where there is no need for wet cleaning. Although it is washed off quite quickly, it is practical, beautiful, economical and safe for health material, and its price is really affordable.
Acrylic latex paints are water-resistant enough to paint concrete or plastered surfaces, as well as brick and plasterboard walls. It dries quickly and does not smell, it’s non-toxic and environmentally friendly and looks nice. Depending on the main components in the composition, the types are divided into:
- Acrylic latex paint, different from the simple acrylic with the addition of latex, which gives elasticity, firmness and durability. Of course, it costs more, and it is more frequently applied in the exteriors.
- Silicate paint is ideal for interior and exterior painting on brick cement concrete or limestone walls and ceilings. It is not afraid of rain and snow, while special additives provide high quality and reliable paint adhesion to the surface, resulting in reduced expenses. A trendy option, the materials are manufactured by the leading, innovative firms like Britannia, focused on manufacturing of exterior wall coatings
- The silicone paint is the most popular of all types of water-based paints. Due to emulsify silicone resin this paint is strong enough to repel water, resistant to temperature changes and mechanical stress. Therefore, it is used for painting the facade of buildings and areas of buildings. One of the significant drawbacks is poor air permeability, elevated levels of moisture and the risk of mold formation.
Technical characteristics overview
As a rule, latex paints are made of latex, a filler, a thickening agent and an antiseptic. The usage of water-based paint is calculated basing on a single layer of paint, and typically varies in the range of 150-250ml per square meter, depending on the absorbency of the surface. Viscosity indicates the extent necessary to dissolve the dye mixture with water according to the type of tool used for application to the surface. Viscometer measured a viscosity which should vary between 40 – 45 stokes when using a brush or roller, and 20 – 25art. for the spray gun.
Latex paint drying time period cannot be specified exactly because it depends on factors such as temperature and humidity in the range of 2 – 24 hours. The indoor temperature during the painting work needs to be higher than 20°C and the humidity not lower than 65%.
For latex paint coating on various surfaces you may want to employ a brush or roller, but it is going to be a long and laborious work. Spray gun for applying emulsion paint will greatly facilitate the process of work. Arm yourself with the device and you will be paint to cover a larger area in a significantly shorter period of time. Spray decreases the consumption of the material, the layer on the output has an optimal thinness, gets evenly distributed and dries quickly.
