The Armor L3000 is a water-based lithium silicate concrete densifier and surface hardener. It chemically reacts with the concrete to form a permanent CSH crystalline structure within the pores that will increase the strength of concrete by up to 45%.PROFESSIONAL GRADE LITHIUM SILICATE SEALER: The Armor L3000 chemically reacts with the free lime and calcium in the concrete to form a permanent Calcium Silicate Hydrate crystalline structure within the pores.INCREASES STRENGTH UP TO 45%: The CSH crystals formed during the chemical reaction will help to increase the strength of concrete by up to 45%.REDUCES DUSTING AND DETERIORATION: The increased strength and density gained by the formation of the CSH crystals in the pores will help to reduce dusting and deterioration caused by surface abrasion.WON"™T CHANGE THE LOOK OR COLOR: The Armor L3000 works entirely below the surface and won"™t leave behind a visible film or coating. The concrete will look and feel natural.LONG LASTING: The CSH crystals left in the pores of the concrete are permanent and can only be removed by means of mechanical grinding.READY TO USE: The Armor L3000 is ready to use. Simply add to a sprayer and apply! One gallon covers up to 200 square feet per gallon. Smooth, absorbent surfaces can get up to 400 square feet per gallon.EASY TO MAINTAIN: There is no maintenance with the Armor L3000. Once applied, you don"™t need to apply it again unless you desire an even stronger surface.VERSATILE: The Armor L3000 is great for use on fully cured unsealed interior and exterior concrete.
