Dusting Preventive and Polisher Concrete Surface Hardener

LH 230 is lithium silicate based, capillary effected, liquid surface hardener with low viscosity that protects the surface from dusting and abrasion by being applied on concrete and cement based floors. It penetrates deeply into the surface zone of the concrete and cementitious screeds and reacts to form insoluble calcium silicate hydrate in existing pores.

• Indoor and outdoor applications,
• In concrete floors, cement based screeds, tile and stone covered floors that are required to be hardened and dust free,
• In factories, industrial fields and mechanical workshops,
• In storages and garages,
• In aircraft hangar and helicopter pad.

• Increases abrasion and dusting resistance of cement based surfaces.
• Makes a silky and gloss appearance layer on the surface.
• Creates water impermeable, dust repellent surface.
• Provides permanent and efficient durability.
• Prevents crack formation on the concrete.
• Water vapour permeable.
• Environment friendly.

Preparation of Substrate

Application surface must be dry, clean and clean off materials which prevent bonding, such as dust, oil, rust and remove loose pieces.

Application Method

LH 230 is ready to use material. It should be applied on the fresh concrete or screed surface with using spray gun uniformly. It must be applied as one layer with filling all the porous. Surface should be looked wet within 15-20 minutes after application. If surface is dried quickly, one more layer application might be needed. The treated surface is ready to use after 1-2 hours. The final strength is achieved after 7 days.
