LATICRETE 3701 Lite Mortar – Lightweight Thick-Bed Performance

LATICRETE 3701 Lite Mortar is a polymer-fortified, lightweight mortar engineered to deliver the same high-strength results as a traditional thick-bed system in a bag that weighs only 30 lb. By replacing heavy aggregates with advanced lightweight fillers, each bag covers the same square footage as a 60 lb 3701 Fortified Mortar Bed while cutting load, freight, and installer fatigue in half.
