A premium one-part formula with high, fast bond strengths and flexibility to resist horizontal movement and separate substrate cracks up to 1/8" (3 mm). For time-limited commercial and residential installations with very demanding conditions, it is used as a mortar or in a thin or medium mortar bed up to 19 mm (3/4'') thick for horizontal surfaces after the laid. The medium mortar bed provides unparalleled sag-free support for laying larger tiles and stones. No need for additives to meet requirements for compressive strength and optimal flexibility and bonding. The rapid installation formula allows the grout to be installed in less than 3 hours and traffic is permitted after 4 hours. A 13.6 kg (30 lb) bag covers the same area as a 22.68 kg (50 lb) bag of traditional mortar. Use on interior or exterior floors, countertops and walls. Formulated with recycled materials and receives LEED certification. Exceeds ANSI A118.4, A118.15 and A118.11 standards without the addition of additives.
- Quick drying - grouting in 3 hours, traffic possible in 4 hours
- Unmatched bond strength and flexibility
- Sag-free for floors, sag-resistant and non-slip for walls
- Lightweight - 30 pounds covers the same area as 50 pounds of traditional mortar
