MR-911G Stair Tread/Tile Adhesive

$50.17

Mannington MR-911 is a solvent-free acrylic adhesive formulated for installing Mannington commercial rubber flooring, Burke LVT, and vinyl or rubber stair treads on porous and non-porous substrates. Ready to use with no mixing required, it's a practical everyday installer adhesive — low VOC, non-flammable, and CRI Green Label Plus certified. Works on suspended wood floors (APA approved), and concrete above, on, or below grade where moisture is within limits. For hospital beds and heavy rolling loads, MR-725 is required instead. Available in 1 gallon and 4 gallon pails.

Moisture note: Not suitable over slabs with moisture vapor emissions from water intrusion or hydrostatic pressure, or slabs without a vapor retardant membrane. Test moisture before application — exceeding limits voids warranty. Determine substrate porosity before selecting trowel type — porous and non-porous substrates require different trowel notch profiles and yield different coverage rates.
