Mapei Mapegrout Patch 218 General Purpose, Shrinkage-controlled, Fibre-reinforced, Patch Repair Mortar 25KG (Grey)
- Model: MP-MP218
Description
• 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.
Features
• Purpose-made for patch repairs
• Easy to apply for wall & overhead repairs; no formwork needed
• Dries without shrinkage & cracking
• Repaired area remains level even after drying
• Fast drying
• High strength
• Colour: Grey.

Where To Use
• Mortar for crack-resistant patching and resurfacing of concrete substrates including overhead surfaces in repair, fixing and general construction works.
Some application examples
• Repair of concrete surfaces damaged by rusting reinforcement bars or by impact loads.
• Securing foundation and anchor bolts, pipe-clips, sanitary ware, hinges.
• Repair of concrete conduits, drains, tanks, etc.
• Filling concrete cavities in electrical, piping and air-conditioning works.
• Repair of surface irregularities including exposed aggregates, joints between new and old concrete, tie-rod holes in formwork concrete, protruding steel, etc
• 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.
