Custom MegaLite Mortar - 30 lb

Overview

MegaLite is a lightweight, high-flexibility mortar for large and heavy tile that needs strong bonding and non-sag, non-slump support. A 30-pound bag provides coverage comparable to a 50-pound bag of traditional mortar, reducing bag weight without sacrificing the specified coverage area.

Features

• Approximately 40% lighter than traditional mortar.
• High flexibility helps isolate supported horizontal substrate movement.
• Sag- and slip-resistant for walls; non-slump support for floors.
• Contains recycled material and is not formulated with silica sand; follow the safety data sheet for handling precautions.

Applications

Use MegaLite for suitable interior or exterior floor and wall tile, including specified pool, fountain and water-feature assemblies. It is useful where large tile, heavy stone and higher bond/flexibility demands make a lightweight premium mortar appropriate.

Selection and Use

• Confirm the substrate and tile type first. Plywood and gypsum have dry-area restrictions; do not directly bond to OSB, hardwood, metal, fiberglass or plastic.
• Moisture-sensitive and resin-backed stone require an epoxy recommendation. Ask CUSTOM about clear glass, large glass or stone deflection requirements.
• Use a notch that collapses mortar ridges effectively; CUSTOM does not recommend a 1/2-inch square notch. Provide at least 80% contact in dry areas and 95% in wet/exterior work, including support at tile edges.
• Allow about 24 hours before grout/light traffic and 7–10 days before heavy traffic when conditions and the assembly permit. For submerged work, wait 14 days after final grouting before filling at the specified conditions.
• Crack-prevention flexibility does not correct structural defects. Plan any required waterproofing and movement joints as separate parts of the assembly.
