Mapei ECO 350 Universal Adhesive 3.78 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. Out of a 3.78 L pail expect 185 to 245 sq ft using a 1/32" x 1/16" x 1/32" U-notch. Over a square 1/16" notch, which is what vinyl-backed carpet takes, it drops to 125 to 185 sq ft a gallon. 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. Approved substrates are 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. In stock in Mississauga and Barrie.
