DMX 1-STEP 2.0™ Advanced Vapor Barrier Underlayment

Advanced Moisture Protection

DMX 1-STEP 2.0™ is a professional flooring underlayment and vapor barrier designed to help protect finished floors installed over concrete. Its dimpled construction creates a continuous air gap beneath the flooring, allowing trapped moisture to evaporate naturally and helping reduce conditions that may contribute to mold growth.

Warmer, More Comfortable Floors

The insulating closed-cell foam helps separate the finished flooring from the cold concrete below. Independent product information from the manufacturer indicates that the system can increase floor surface temperature by up to 12°F, helping create a warmer and more comfortable living space.

Fast and Convenient Installation

DMX 1-STEP 2.0™ installs directly over suitable concrete subfloors without requiring a plywood or OSB layer. Its lightweight roll format is easy to handle and can help reduce installation time, additional material costs, and unnecessary floor height.
