DEX-O-TEX M-E FLOORING
(Waterproof Mechanical Equipment Room Flooring)

1.) PRODUCT DESCRIPTION

A.) Composition

Dex-O-Tex M-E Flooring is a multi-layered troweled application designed for use as a waterproof flooring system in upper level mechanical equipment rooms.

The material is applied in individual troweled layers which form, successively, an elastic latex fabric re-inforced waterproof membrane, an integral waterproof base turned up at walls and equipment pads, and a durable finished floor.

Dex-O-Tex M-E Flooring components are all combinations of liquid rubber latex polymers incorporating dehydrating powder, vulcanizers and special aggregates. The waterproof membrane and waterproof base are re-inforced with a polypropylene mesh fabric. Topmost application consists of a pigmented acrylic coating.

The product is designed for application over concrete or masonry surfaces – new or existing. Separate specifications are available for wood or plywood surfaces – consult Crossfield Products Corp.

Dex-O-Tex M-E Flooring components are entirely water-based and contain no hydrocarbon solvents. They have no toxic odor during application, are not flammable, and are environmentally safe.

The approximate thickness of Dex-O-Tex M-E Flooring is 1/8" (3.17 mm). It is available in a wide range of standard colors.

Request Crossfield Products Corp. Design Guide 6 ("Design Ideas for Waterproofing a Mechanical Equipment Room") for detailing information.
