Sika - Sika Primer MB waterproofing primer

Epoxy, solvent-free, two-component primer and waterproofing substrate prior to bonding wooden floors with SikaBond adhesives.

Features

• binary
• solvent-free
• reactive epoxy
• good penetration and stabilization of the substrate
• low viscosity
• easy application
• shortens the time of work
• also suitable for old substrates
• can be used with heated floors

Application

The product is used in combination with SikaBond wood floor adhesives as: impregnation to strengthen concrete substrates, screed in anhydrite, cement mortar; as an anti-damp buffer for cement substrates with a moisture content of up to 6% CM (tested with the carbide method); as a preparation that improves adhesion to sanded asphalt surfaces, surfaces with remains of old glue and mortars.
