Laticrete LHT Large Heavy Tile Mortar — Polymer Modified Thin-Set Adhesive
Laticrete LHT Large Heavy Tile Modified Thin-Set Mortar is formulated to provide reliable, high-performance installation for large format tile, porcelain, marble, and natural stone. Its polymer-modified composition delivers strong adhesion and flexibility, ensuring consistent performance on both interior and exterior projects.
The high-build, non-shrink design allows installers to achieve thicker mortar beds—up to 3/4″ (19 mm)—without compromising stability or bond strength. This capability helps reduce lippage and supports heavy tile and stone installations with improved efficiency. Designed as a one-step solution, it simplifies the installation process while maintaining professional-grade results across a wide range of substrates.

Technical Data
Installation:
All surfaces should be between 40°F (4°C) and 90°F (32°C) and structurally sound, clean and free of all dirt, oil, grease, paint, concrete sealers or curing compounds. Rough or uneven concrete surfaces should be made smooth with Latex Portland Cement Underlayment to provide a wood float (or better) finish. Dry, dusty concrete slabs or masonry should be dampened and excess water swept off. Installation may be made on a damp surface. New concrete slabs shall be damp cured and 28 days old before application. There is no minimum cure time for concrete slabs when mortar is mixed with latex additive. All slabs must be plumb and true to within 1/4″ (6 mm) in 10 ft (3 m). Expansion joints shall be provided through the tile work from all construction or expansion joints in the substrate. Do not cover expansion joints with mortar.
