  • Friendly to human health and the environment.

Application instruction

Surface preparation

  • The surface must be clean, free from standing water, and free from easily peeling contaminants.

  • Dust and burrs must be removed using suitable mechanical tools, for example a sandblasting machine.

  • Steel reinforcement and starter bolts must be cleaned of rust and dust using a wire brush or sandblasting.

Mixing

  • Before application, Components A and B must be thoroughly mixed at the correct ratio.

  • Use an electric mixer or a pneumatic mixing paddle at a speed of 300-600 rpm.

  • The minimum mixing time is 03 minutes; mixing may continue longer until the mixture reaches the required homogeneity and uniform color.

Application

  • After mixing, use a stiff brush or a short-nap roller to firmly apply the mixture onto the cleaned and prepared old concrete surface.

  • For damp surfaces, ensure there is no standing water and that the surface is completely covered with BestBond EP752.

  • Pour the new concrete while the BestBond EP752 layer is still wet and has not yet cured.

Cleaning

  • Use water and soap to clean tools immediately after use and before the mixture begins to cure.

  • If the material has cured, tools can only be cleaned using suitable mechanical methods.

Safety

  • Both components are non-hazardous; however, they may cause skin allergies upon prolonged contact.

  • Gloves, masks, and safety goggles should be worn during application.

  • If the product splashes into the eyes or mouth, rinse immediately with water and go to the nearest medical facility for timely treatment.
