820 DUSTLESS Merlite

820 DUSTLESS Merlite 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. 820 DUSTLESS Merlite may be applied from 3/32” to 3/4” (2.4 mm to 19 mm) thickness for greater support under large and heavy tiles and stone. It is optimal for both interior and exterior installations of tile in most residential and commercial floor and wall applications. Innovative DUSTLESS Technology (DLT) produces significantly less dust than ordinary thinsets, promoting cleaner working conditions and reduced mess. It uses less water, is creamier and easier to spread.
