MasterKure HD 300WB is a magnesium fluorosilicate concrete hardener and dustproofer that bonds chemically with the concrete to strengthen and harden floors that are porous, readily absorptive, and only moderately hard. 

Product Features

• Hardens and densifies concrete floors to reduce absorption and prolong service life

• 100% reactive with the free lime in concrete to produce a dense, abrasion-resistant yet breathable surface

• Tightly binds together the cement, sand, and aggregate for improved chemical resistance

• Non-film forming, resulting in reduced cleaning and maintenance costs

• Compatible with most resilient tile adhesives 

Applications

• Interior and exterior

• Floors requiring a hard, dense, chemical- resistant finish

• Floors subject to heavy traffic and abrasion

• Floors that must resist penetration of contaminants 

Substrates

• Concrete

• Terrazzo (non-resinous)
