Product Description

Mapei Mapefer 1K is a single-component corrosion-inhibiting cement mortar for the protection of reinforcing rods and adhesion improver for concrete repair mortars.

Mapei Mapefer 1K has been formulated by Mapei Research & Development laboratories based on polymers in powder form, cementitious binders and corrosion inhibitors to be applied on reinforcing rods to prevent rust formation. Mapefer 1K provides corrosion inhibition action due to its high alkalinity, excellent adhesion to metal and the presence of corrosion inhibitors. Mapefer 1K is resistant to saline fog and impermeable to water and aggressive gases in the atmosphere therefore protecting the rebars.

Best Uses

Mapei Mapefer 1K is suitable for use on underground concrete constructions for the protection of reinforcing rods and as an adhesion improver for concrete repair mortars.


Mapei Mapefer 1K is supplied in powder form and is mixed with water to form a lump-free homogeneous paste. Apply Mapefer 1K using a paint brush within 1 hour of mixing. Two coats are recommended, the second coat to be applied within 2-24 hours of application of the first coat, to a minimum thickness of 2mm.
