3 Product Description
A premium one part formula with the high, fast bond strengths and
flexibility to withstand horizontal movement to isolate substrate cracks
up to 1/8" (3 mm). For time-critical commercial and residential
installations under the most demanding requirements, capable of thin-
set or medium bed application up to 3/4" (19 mm) thick on horizontal
surfaces after beat in. Non-slump, medium-bed features provide the
ultimate support for large format tile and stone. No need for two part
additives to meet high bond and flexibility or compressive strength
requirements. The rapid setting formula allows grouting in less than 3
hours, traffic in 4 hours. A 30 lb (13.6 kg) bag covers the same area
as a 50 lb (22.68 kg) bag of traditional mortar. Use for interior or
exterior floors, countertops and walls. Formulated with recycled
materialcontributestoLEED®certification.ExceedsANSIA118.4,
A118.15 and A118.11 without the need for additives.
