Applications
BestHard MA152 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 MA152 is suitable for floor surfaces subject to severe abrasion requiring exceptional hardness, such as: warehouse floors, factory floors, garages, parking lots, traffic lanes, docks, aircraft hangars, etc.

Application instruction
SURFACE PREPARATION:
The concrete must be designed with technical properties suitable for its intended use. During concrete placement, vibration compaction and surface leveling must be carried out in accordance with required standards.
APPLICATION PROCEDURE:
Application:
BestHard MA152 should be applied manually in two layers. Typically, about 2/3 of the total quantity is used for the first layer, and the remaining for the second layer.
When bleed water on the concrete surface starts to evaporate and the concrete reaches a plastic state (before initial setting), perform initial troweling to level the surface, while minimizing the mixing of cement slurry onto the surface of BestHard MA152 at later stages.
After initial troweling, evenly broadcast the first layer onto the concrete surface. Wait until BestHard MA152 has absorbed sufficient moisture from the concrete, darkens in color, and the concrete reaches a suitable plastic consistency (without excessive indentation). Then use a power trowel at low speed with minimal blade angle to press the BestHard MA152 into the concrete surface until a uniform wet slurry appears on the surface.
BestHard MA152 should be applied first in areas that dry quickly such as column bases, wall bases, doorways, and windows.
Continue applying the second layer immediately after finishing the first layer. However, ensure that any areas with insufficient coverage from the first layer are compensated to achieve full and uniform coverage. Troweling is carried out similarly to the first layer, with appropriate adjustments to blade angle and rotation speed.
Finishing:
For higher gloss, increase the blade angle and trowel at higher speed.
Color uniformity, gloss level, and mechanical properties of the product depend greatly on the application process. Proper execution ensures optimal performance.
Curing:
Immediately after application, proper curing must be carried out to prevent rapid moisture loss, which may lead to surface cracking. It is recommended to use BestCure curing compound to prevent cracking and surface discoloration, especially for colored BestHard MA152.
