Roberts 2350 Universal Adhesive 3.78 L

2350 Universal Adhesive is a hard-set adhesive for resilient flooring. It is for LVP and LVT, vinyl-backed carpet tile, fibreglass-backed sheet vinyl, rubber sports flooring and rubber tile. Out of a 3.78 L pail expect 170 to 190 sq ft using a square 1/16" notch over a porous substrate. Over semi-porous or non-porous it takes a 1/16" x 1/32" U-notch for 250 to 300 sq ft a gallon. LVP, LVT and carpet tile on a 3/32" flat-top V-notch come down to 100 to 120. Open time up to 15 minutes, working time 60 minutes wet, and it cures in 12 to 24 hours. Pressure sensitive for the first hour, then it cures to a hard set. Rated to 8 lb MVER, 85% slab RH and pH 10. Keep traffic and heavy loads off for 24 to 48 hours. Protect from water for 4 days and from standing water for 30. It is approved over concrete, underlayment-rated plywood, terrazzo, clean wax-free VCT, prepared sheet vinyl, primed gypcrete and radiant floors below 85F. Not over self-stick sheet vinyl. Not for perimeter-adhered flooring, and never fill or cover an expansion joint with it. Interior only. The room needs to be 65 to 95F at 65% humidity or less for 48 hours before, through the job, and 72 hours after, and kept there for the life of the floor. On the shelf in Mississauga and Barrie if you are picking up tile anyway.
