TECHNICAL CHARACTERISTICS
Mapegrout Patch 218 is composed of cement, graded aggregates, special additives and synthetic fibres in a formula developed in the MAPEI research laboratories.

When mixed with water to the recommended ratio Mapegrout Patch 218 forms an easy-to-apply, thixotropic mortar that can be applied in thicknesses up to 30 mm on overhead and vertical surfaces without
formwork support.

When fully cured, Mapegrout Patch 218 has:
◼️ high flexural and compressive strengths;
◼️ modulus of elasticity, thermal expansion coefficient and permeability coefficient similar to that of high quality concrete;
◼️ excellent adhesion to prepared concrete surfaces.

RECOMMENDATIONS
◼️ Do not use Mapegrout Patch 218 to repair surfaces subject to high abrasion. Use Mapegrout Thixotropic.
◼️ Do not use Mapegrout Patch 218 on smooth concrete surfaces. Roughen the surface thoroughly.
◼️ Do not use Mapegrout Patch 218 for pouring or pumping into formwork. Use Mapefill 318.
