G-26 Underlayment

G-26 Underlayment

Highly-flexible, rubber latex underlayment for thinner smoothing applications.

G-26 Underlayment is an extremely smooth, rubber latex underlayment designed for thinner smoothing applications such as lightly-eroded concrete or wood floor surfaces.

The trowel-applied system consists of a synthetic copolymer cementitious underlayment that is installed from featheredge to multi-inch thickness, making it an ideal underlayment for vinyl composition tile, carpet, and other resilient floor finishes. It’s highly durable and suitable for pitching, patching, filling voids, and creating slope for drainage. It’s also flexible for use on both interior or exterior substrates.
