Description

EMC is a 100% acrylic based elastomeric high build protective wall coating. Its’ unique formulation permits bridging of minor cracks which can normally appear in walls. A breathable coating, EMC provides an effective weather shield for wall surfaces.

Advantages
  • High flexibility; up to 300% elongation with 100% recovery
  • Retains flexibility at low temperatures to -40°C
  • Low dirt pick-up (wall remains cleaner even in high pollution areas)
  • Easy to apply
  • Excellent adhesion to cementitious substrates
  • Permeable; allows wall to breathe and trapped water vapour in wall to evaporate
  • Long-term weatherability
  • Excellent resistance to ultraviolet rays
  • Permanently bridges existing minor cracks
Uses

EMC can be applied over almost any solid substrate including but not limited to the following:

  • Clean concrete and masonry and all other types of cementitious substrates
  • Over solid clean substrates, including stucco with cracks
  • Exterior and interior surfaces
  • Stone, precast, exposed aggregate surfaces
  • Ideal for recoating existing stucco surfaces

Coverage
  • 4.9 m2/L (200 ft2 / gallon) @ 10 mils WFT (5 mils DFT)
  • 46.5 m2 / pail (500 ft2 /pail) @ 2 coats (10 mils DFT)

Coverage rate will vary according to the porosity and roughness of the surface being coated. Very rough or porous surfaces may require more than 2 coats to provide the required minimum 10 mils dry film thickness.
