Superior Grade Lightweight Flexible Lht Mortar

SikaTile-500 LHT Lite is a superior grade, single-component, non-sag, non-slip lightweight polymer-modified mortar for interior and exterior setting of large and heavy tile and natural stone. Its 30 lb. bag provides the same coverage as a typical 50 lb. bag of mortar and may be applied from at 3/32 to 3/4 (2.4 mm to 19 mm) thickness to provide better support under large and heavy tiles and stone and can be used for both interior and exterior installations of tile in most residential and commercial floor and wall applications. SikaTile-500 LHT Lite, features innovative Dustless Technology producing approximately 80% less dust than ordinary thin sets and is designed to promote cleaner working conditions and reduce mess. It uses less water and is creamier and easy to spread.

• Non-sag and slip resistance for large and heavy tiles
• Non-slumping formula eliminates tile lippage
• May be applied up to 3/4 (19 mm) thick on horizontal applications

Cure Time

Product Curing time is affected by ambient and surface temperatures and humidity. Use the following as a guideline. Allow 24-48 hours before grouting and light traffic, and 7 days before heavy or vehicular traffic. As necessary, use plywood or other load distributing protection when moving heavy equipment across tiled assembly.

MIXING

WALLS: For non-sag and slip resistance; In a clean container, add approximately 5 quarts (4.7 liters) of clean potable water, then add the contents of the 30 lb. (13.6 kg) SikaTile-500 LHT Lite Mortar. Mix thoroughly by hand or with a slow speed mixer to a smooth, thick, trowelable consistency.

FLOORS:For use on floors or as a thin set; In a clean container, add approximately 5.75 quarts (5.4 liters) of clean potable water, then add the contents of the 30 lb. (13.6 kg) SikaTile-500 LHT Lite Mortar. Mix thoroughly by hand or with a slow speed mixer to a smooth, thick, trowelable consistency. Mortar consistency shall be such that when applied with the recommended notched trowel to the substrate, the ridges formed in the mortar do not flow or slump. During use, stir mortar mix occasionally. Do not add additional water. Do not add latex liquid additives to SikaTile-500 LHT Lite Mortar.

APPLICATION

Read all installation instructions before installation. Choose a notched trowel with sufficient depth to achieve more than 80% mortar coverage and transfer to substrate and back of tile to both the tile and substrate for all interior applications, and more than 95% for exterior, commercial floor and wet applications, back-butter the tile to meet these requirements. With pressure, apply a coat of mortar by using the flat side of the trowel to key the mortar into the substrate. With the notched side of the trowel, apply additional mortar by combing it in a single direction parallel to the shortest dimension of the tile. Spread only as much mortar as can be tiled before the product skins over. Open time can vary with jobsite conditions. Set tiles firmly into the wet mortar and push the tiles back and forth in a direction perpendicular to trowel lines to collapse the mortar ridges and to help achieve maximum coverage.

CLEANING OF TOOLS

Clean tools and tile with water before the material dries.
