VLW Lightweight Underlayment
(MIL SPEC MIL-PRF-3135(H), Type III, Class 2)

Dex-O-Tex VLW Lightweight Underlayment conforming to military specification MIL-PRF-3135(H) Type III, Class 2, Grade B.  It is a 100% solids epoxy resin base mixed with a very lighweight aggregate to form a trowel applied decking underlayment for general use under all deck covering materials.  Due to the rapid cure of VLW Lightweight Underlayment, it can be installed with minimum downtime.  It can be applied directly to clean metal or steel.  Or steel coated with pre-construction primer (PCP), without the need for a separate bond coat, mechanical anchors or other devices welded to the surface.  It offers every advantage for lightweight filler sloping/leveling compound for quick turnover maintenance and/or repair installations.

Typical Uses:

VLW Lightweight Underlayment can be used to level or slope a deck and provide a smooth even surface over metal, aluminum or steel for subsequent application of any deck covering problems:
