LATICRETE 3701 Lite Rapid Mortar – Lightweight, Fast-Curing Thick-Bed Performance

LATICRETE 3701 Lite Rapid Mortar (often listed as 3701 Lite Mortar R) is a polymer-fortified, rapid-setting thick-bed and render mortar that cures in as little as 1½ – 2 hours. Each 30 lb (13.6 kg) bag delivers the same coverage as a conventional 60 lb mortar bed while slashing load, freight costs, and installer fatigue in half.

Why Choose 3701 Lite Rapid Over Standard 3701 Lite?

Rapid turnaround. Initial set in 35–45 min, ready for foot traffic in 90–120 min, and heavy traffic in 72 hrs.
50 % weight reduction with identical coverage. Same 12 ft² per ½-inch bed as the standard version.
Water-only mix. No latex admix required—just add water on site.
OSHA silica-safe. Contains no respirable crystalline silica above the action level for a safer jobsite.
Polymer-fortified strength. 2-hour compressive strength reaches 600–900 psi (mortar-bed test).
True versatility. Approved for horizontal, vertical, overhead, interior, exterior, wet-area, bonded & unbonded applications.
