Applications
BestHard MA153 is used to increase the surface hardness of concrete floors and slabs, enhancing abrasion resistance, scratch resistance, and reducing surface dust generation during use.
BestHard MA153 is suitable for use on heavily abrasion-prone floor surfaces requiring exceptional hardness, such as: warehouse floors, factory floors, garages, parking lots, traffic lanes, docks, aircraft hangars, etc.
Advantages
- Premixed, easy apply, high and consistent quality.
- Improves resistance to abrasion.
- Improves resistance to impact.
- Improves resistance to oils and greases.
- Improves smoothness.
- Improves smoothness.
Application instruction
SURFACE PREPARATION:
Concrete mix design mush be corresponding with using purpose. The vibrating and leveling work should be in right way to get optimum result.
APPLYING PROCEDURE:
Applying:
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.
CLEANING:
Clean tools and equipment immediately after completing the work and before the material hardens using clean water and soap. Once the material hardens, clean only using appropriate mechanical methods.
SAFETY:
BestHard MA153 is non toxic. It can cause irritation with sensitive skin. Gloves, mask, goggles should be worn
