Mapei ECO 350 Universal Adhesive 15 L

ECO 350 Universal Adhesive is a professional adhesive for solid vinyl flooring. It is for solid vinyl sheet, plank and tile, homogeneous PVC, VCT and solid vinyl-backed carpet. A 15 L pail is roughly 733 to 971 sq ft with a 1/32" x 1/16" x 1/32" U-notch. Flash time is 15 minutes over a porous substrate and 25 over a non-porous one. Working time runs 1 to 2 hours depending on the floor. It is transitional pressure sensitive, so the floor goes down either after a short flash or once the adhesive turns tacky. Rated to 5 lb MVER and 80% slab RH. Light traffic at 24 hours and heavy traffic at 72. It is approved over concrete, exterior-grade plywood and approved wood underlayments, cement terrazzo, levelling compounds, primed gypsum underlayment, and radiant heat. Never over an asbestos-containing substrate. Interior only. Check the data sheet edition before you trust a number from elsewhere. The 2010 sheet gave 3 lb MVER and listed laminate and rubber tile; the current 2025 sheet gives 5 lb and lists neither. Both the Mississauga and Barrie stores carry it.
