Roberts 6300 Pressure Sensitive Adhesive 3.78 L

This is 6300 Pressure Sensitive Adhesive, a pressure-sensitive flooring adhesive. It is for carpet cushion, Enhancer-backed carpet tile, recycled non-foam PVC, and solid vinyl, rubber or urethane. For LVT it is approved only up to 12" x 12". A 3.78 L pail is roughly 170 to 190 sq ft with a square 1/16" notch, carpet tile. A medium-nap roller stretches it to about 300 sq ft a gallon. Laid permanently it opens for 20 minutes with 40 of working time. Laid releasable it tacks for up to 45 minutes and holds 12 hours of working time. It does both: dry for a releasable floor you can lift and replace, or wet-set for a permanent one. Rated to 10 lb MVER, 90% slab RH and pH 10. Approved substrates are concrete, prepared terrazzo, underlayment-rated plywood, primed gypcrete, roughened steel and VCT in light traffic only. Do not use it over VCT in heavy traffic. Do not use it under LVT larger than 12" x 12", which rules out plank. Foam-backed carpet will not give you the releasable feature. Never fill or cover an expansion joint. Interior only. On the shelf in Mississauga and Barrie if you are picking up tile anyway.
