Much stronger than conventional and pre-mixed grout, Super Grout Additive is used where those grouts tend to fail and crack, especially corners. Regular grout is not flexible, nor strong enough to withstand minor movements which causes grout to crack.
Think of Super Grout Additive as not only a very strong grout, but also the professional's choice for caulk and silicone replacement. Caulk and silicone is typically used for areas including: sinks, shower glass enclosures, shower drains, chipped tiles and all corners including where countertops meet backsplashes.
Use any sanded grout for professional color matching your existing grout. Easy to mix and apply, never needs to be sealed and fixes grout cracks permanently. Used by tile professionals everyday!
