Mapei Mapegrout Patch 218 General Purpose, Shrinkage-controlled, Fibre-reinforced, Patch Repair Mortar 5KG (Grey)

Mapei Mapegrout Patch 218 General Purpose, Shrinkage-controlled, Fibre-reinforced, Patch Repair Mortar 5KG (Grey)

Description 

• Mapegrout Patch 218 is composed of cement, graded aggregates, special additives, and synthetic fibers 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.

Features

• Fiber-reinforced shrinkage-controlled patch repair mortar.

• High flexural & compressive strength.

• Excellent adhesion to the concrete surface.

• Easy to apply.

• Very fast drying.

• Color: Grey.

• Reprofiling damaged corners of pre-cast panels.

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 the formwork. Use Mapefill 318.

• Do not add cement or admixtures to Mapegrout Patch 218.

• Do not add water once the mix has begun to set.

• Do not use Mapegrout Patch 218 at temperatures lower than +5°C.

• Do not use Mapegrout Patch 218 if the bag has been damaged or opened.
