Treadstone® gypsum underlayments are a proprietary cementious formulation with the fire-resistive, non-shrinking, fast cure qualities of a gypsum underlayment with enhanced compressive strength, high flow and abrasion resistance — eliminating the “soft, chalky” negative association of gypsum products of the past.
Fire-Rated Performance with High Flow
Our innovative Treadstone® FR25 gypsum concrete formulation adds the cementitious properties of high flow, high strength and abrasion resistance to the fire-resistive, non-shrinking, fast cure properties of gypsum underlayment.
Fire-Rated Performance with Higher Strength
This advanced gypsum concrete formulation of Treadstone® FR30 gypsum underlayment includes the fire-resistive and high flow properties of Treadstone® FR25 , but with an additional compressive strength of up to 3800psi.
Fire-Rated Underlayment for Pre-Pours
Treadstone® FR30P pre-pour underlayment provides an effective solution to pre-pour projects of underlayment between interior walls, and below locations of tubs, shower enclosures and other areas containing appliances installed before the installation of underlayments.
Underlayment & Leveler Substrate Bonding
Formulated Materials® APS self leveling concrete primer is a low VOC acrylic primer and sealer for improved performance of fire-rated underlayments and self-levelers by providing a solid bond to the substrate during installation.
Pre-Pour Surface Prep for Wood Substrates
Treadstone® TP1 pre-pour surface primer is a low VOC acrylic primer suitable for priming wood substrates prior to installing Treadstone® fire-rated underlayments and self levelers.
Multi-Purpose Moisture-Control Felt Underlayment
Treadstone® Technical Felt synthetic felt underlayment is a reinforced, durable, leak-proof, vapor retarding membrane that speeds the preparation of subfloors.
