• Creates a contact layer between the existing substrate and the new layer of mortar
• After drying, the sand from the preparation creates a rough surface, improving the adhesion of new layers
• Very good adhesion to smooth and tight surfaces
• The yellow color of the preparation makes it easier to distinguish between primed and non-primed places
• Alkali resistant
• One-component
• Ready to use
• For indoor and outdoor use
• It does not contain solvents

Weber.prim contact is intended for:

• priming smooth and low-absorbency substrates, e.g. concrete, terrazzo, OSB boards, ceramic tiles, stone, etc., before laying floor mortars, adhesive mortars, plasters, etc.
