For special reinforcing of floor and slab surfacing in order to increase the resistance to abrasion and hence to reduce the formations of dust to severe mechanical wear such as: warehouses, quays, parking lots and mechanical engineering workshop, aircraft hangers, ...

Preparation:

• Concrete mix design mush be corresponding with using purpose. The vibrating and leveling work should be in right way to get optimum result.
  

Placing:

• BestHard MA153 should be applied in two layers by hand. Approximately 2/3 of quantity should be applied in the first layer and the balance in the second one. After the concrete has been evaporation of bleeding water, the preliminary
  floating is applied to leveling the surface and preventing cement slurry from concrete onto hardener in later time.
  
• Disperse the BestHard MA153 powder evenly by hand on the floor surface after preliminary floating. Should apply first on floor areas where the concrete is likely to loose moisture rapidly such as: near by walls, columns, joints and doorways... 
• After the applied BestHard MA153 powder darkens in color indicating absorption of moisture from the concrete and when concrete has stiffened enough to prevent the float blades from digging into the surface, float the applied surface areas using power floats. Float just enough to bring the excess moisture to the surface.
  
• Apply second layer continuously as the first layer. Dispersing the remaining quantity of BestHard MA153 evenly on the first layer surface by hand, compensating with extra material over areas under-applied during the first dispersing. As soon as the second layer has darkened by moisture absorption, float the surface with a power trowel equipped with float blades or disc floats.
  

Smooth finishing:

• For the superior smooth finish, trowel again after further stiffening of the surface with slightly raised blades, but avoid raising them to angle that creates chatter marks or blisters on the surface. If either starts to appear, remove them by reducing the angle of trowel.
  

Curing:

• Start curing immediately after final finishing using a liquid membrane-curing compound such as BestCure to prevent rapid evaporation of water to avoid surface split or spotted formation.
  

Safety:

• BestHard MA153 is non toxic. It can cause irritation with sensitive skin. Gloves, mask, goggles should be worn
