Brush, roller or spraying.
Stir paint throughly until completely homogenized. Apply on consistent, clean, completely dry surfaces, free from efflorescence (saltpetre) and mould.
Avoid application during strong wind and rain. If paint gets wet during the drying process this can cause snail track blistering leading to surface stains. Dilute the product depending on surface porosity and surface condition.
