Floor Prep

RH95 Moisture Vapour Reduction

RH95 is approved for use EXCLUSIVELY on Interface flooring installations. RH95 is an aqueous acrylic polymer that dries to a clear film that is alkali and water-resistant. It designed for use on interior porous concrete substrates as a penetrating and film-forming polymer to protect Interface flooring installations against moisture readings up to 95% in-situ Relative Humidity (RH), moisture vapour emission rate up to 10 lbs., and pH of 11.0. RH95 is designed and warranted for use only on Interface approved flooring installations.

Spread Rate:
3/8” nap roller with an application rate of 350 - 400 sq ft per gallon

TriSeal Adhesive Residue Encapsulator

TriSeal is a light-colored, high-strength acrylic polymer compound formulated to isolate old cutback and other adhesive residues that would discolor or affect the bond of the new flooring installation. Prior to the installation of floor covering systems, TriSeal provides a clean surface for better adhesive bonds. Black asphalt-based cutback adhesive is highly reactive with vinyl back flooring and must be completely removed until there are no remaining trowel ridges or continuous film. TriSeal can be used to isolate the remaining permanent stain after the cutback has been removed.

Spread Rate:
3/8” nap roller with an application rate of 315 – 360 sq ft per gallon
