LIQUID HARD

LIQUID HARD is a premium hardener, densifier and sealer for concrete surfaces.  Treated surfaces resist damage from water and surface abrasion.  The increased surface hardness reduces dusting and simplifies maintenance producing a cleaner, healthier environment.  LIQUID HARD penetrates into the concrete pores providing a durable and highly reflective concrete surface without producing waste.  

LIQUID HARD is a VOC Compliant (20 g per liter), specially formulated lithium-silicate harder/densifier with no unpleasant or flammable fumes.  LIQUID HARD is safer, faster and easier to apply than conventional sodium or potassium silicate hardeners and will not trigger or contribute to surface ASR (Alkali Silicate Reaction).  This penetrating lithium silicate treatment reacts with the concrete to produce insoluble calcium silicate hydrate within the concrete pores.
