Apply the primer evenly, using a brush, roller or small broom, over the sound, clean and dust-free surface and leave to dry to a clear thin film before applying the tile adhesives. It is important that the primer fill the entire surface to ensure a solid bond of the tile adhesives. Avoid forming of puddles. Extremely porous substrates may require two priming coats.
