Mapei Primer MF Kit

Mapei Primer MF Kit

Mapei Primer MF is a two-component, solvent-free epoxy primer designed for consolidating and waterproofing cementitious substrates and controlling residual moisture before the installation of moisture-sensitive flooring.

Its low-viscosity epoxy formulation penetrates into porous substrates, helping improve surface strength while significantly reducing permeability. It can be used before the installation of flooring such as timber and resilient flooring, subject to the required preparation and installation system. 

Key Features:

• Two-component epoxy system
• Solvent-free formulation
• Helps control residual moisture in cementitious substrates
• Suitable for concrete slabs and cementitious screeds
• Helps consolidate weak or inconsistent cementitious substrates
• High penetrating capability
• Can provide a dustproof treatment to suitable substrates
• Suitable before moisture-sensitive flooring systems
• Can be applied by roller, brush or flat trowel
• Supplied as pre-measured components for mixing

Mixing Ratio:
Component A : Component B = 3 : 1 by weight. 

Coverage / Consumption:
Approximately 0.20–0.30kg/m², depending on the substrate and application.

Typical Applications:
Ideal for treating concrete slabs and cementitious screeds with residual moisture, as well as consolidating weak cementitious substrates before compatible flooring systems are installed.

Always refer to the current Mapei Technical Data Sheet for substrate preparation, moisture limits, number of coats and compatibility with subsequent adhesives or levelling compounds.
