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.
