Wall and grouting paint
Biltema's Wall and Plaster Paint is very diffusion-open, and even allows salts to penetrate through the paint film. If the salts are not allowed to diffuse through the paint, they will become enriched underneath the paint. Salts contain water, which is why frost shattering will be the result if they are not allowed to penetrate out. Any salt efflorescence is easy to rinse off if they do not "rain" away naturally. In combination with the Wall and Plaster Paint a water-repellent façade protection is achieved, which is very diffusion-open. It is important to allow the water in mineral walls to dry out. Water exists in the walls, either capillary-absorbed from the ground or having been evaporated from humans and animal, or from another source. Characteristic for the system is that the water dries out faster than for untreated walls. This is due to the capillary force becomes greater the finer the capillaries are. Biltema's Wall and Plaster paint penetrates deeply and adheres to the inner capillary walls, which consequently become reduced. However, care must always be observed when old acrylic or latex paint is over-painted. Several layers or too thick layers can create too tight a layer with frost shattering as a result. In a system with Wall and Plaster Primer it functions as carbonation retarding.
The substrate must be dry, clean and solid. Wash and rinse. Loose, old paint must be removed. Steel brush scrape away old "plastic paint". Wash, rinse and allow it to dry well. NOTE! Always prime with Wall and Plaster Primer, even on previously painted surfaces. Apply the paint with a roller or brush. After diluting it can also be sprayed.
Do not paint more (thicker) than what is needed for good coverage. Normally one coat. Diffusion openness functions best in this way.
