LS™ is the premium hardener, densifier and sealer for concrete surfaces. This patented formulation is a penetrating lithium silicate treatment that reacts with the concrete to produce insoluble calcium silicate hydrate within the concrete pores. Treated surfaces resist damage from water and surface abrasion. The increased surface hardness imparted by LS™ reduces dusting and simplifies maintenance producing a cleaner, healthier environment. Safer, faster and easier to apply than conventional sodium or potassium silicate hardeners, LS™ will not trigger or contribute to surface ASR (Alkali Silicate Reaction). Premium lithium silicate sealer, hardener & densifier for concrete.
Easy, one step application. No scrubbing. No flushing. No caustic wastewater
May be applied to broom finished, steel troweled, power troweled or burnished concrete finishes
Patented formulation penetrates and reacts quickly to produce better initial and ultimate hardness
Tested and conforms to California Collaborative for High Performance School Indoor Air Quality standards. Use can contribute to LEED® for Schools points (EQ Credit 4)
Provides better abrasion resistance than conventional hardeners
Produces a fast surface gloss which improves with traffic and maintenance
Improves performance, appearance and light reflectance of new or old concrete
Reduces application time and costs of diamond polishing operations
Will not contribute to surface crazing. High lithium content combats surface ASR
Lithium will not absorb water or contribute to floor sweating
Gloss and hardness do not reduce slip resistance
Breathable and UV stable. Will not yellow, discolor, peel or flake
VOC Compliant. Non-flammable. Non-toxic. Low odor
Cures quickly. Most floors can be opened to traffic within one hour of treatment
Treated surfaces are easy to maintain and require no waxing
