A medium strength high build repair mortar meets EN 1504-3 R3 classification.

Available in a 25kg unit.

Technical Description

Mapemortar HB R3 is a premixed powder mortar composed of cement, graded aggregates and special additives from a formula developed in the Mapei research laboratories.

When mixed with water Mapemortar HB R3 forms an easy to apply high build mortar that can be applied withoutslumping even in substantial thicknesses on vertical surfaces without the aid of formwork.

When fully cured Mapemortar HB R3:
• has moderate flexural and compressive strength;
• has a modulus of elasticity, thermal expansion coefficient and permeability coefficient similar to medium strength concrete;
• has excellent adhesion to existing concrete surfaces providing they have been pre-soaked and still damp with clean water;
• reinforcing bars should be treated with Mapefer or Mapefer 1K.
If Mapemortar HB R3 is prepared by only adding water, it should be cured under damp conditions in order to guarantee that the products expansive properties develop correctly and completely.
