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.
TREADSTONE® provides a full line of gypsum underlayments, self-levelers, and acoustic underlayments engineered to elevate the construction industry.
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.
For years underlayment and waterproofing subcontractors have relied on multiple products from multiple manufacturers, resulting in multiple warranties or no warranties at all. Formulated Materials has eliminated the multiple, providing one brand, one warranty.
