Mapei’s Ultraflex LHT SG is a standard-grade, non-sag, nonslump, polymer-modified, large-and-heavy tile mortar and thin-set mortar for interior/exterior installations on floors, walls, and countertops. It is designed for use at 3/32" to 1/2" (2.5 to 12 mm) thickness to give better support under large-format tile.

Formulated with Mapei's Easy Glide TechnologyÔ, Ultraflex LHT SG has a smooth and creamy consistency for ease of application. If mixed with water, it can be applied to a variety of surfaces, including concrete, masonry cement block, brick, render coats and leveling coats. If mixed with Mapei’s Keraply latex additive, it can be applied to ceramic and porcelain tile; quarry tile; VCT; Mapei’s waterproofing, crack-isolation, sound-reduction and uncoupling membranes; and APA Group 1 exterior-grade plywood.
