How to use Romus PVC Cold-Weld Seam Sealer (44 g)
- 1Make sure the subfloor is clean, dry, flat and free of dust, old adhesive, paint or sealers before you open the pail.
- 2Spread with the trowel notch size printed on the pail or bucket label for your specific flooring type — that’s set by the manufacturer for a reason and shouldn’t be guessed.
- 3Follow the open time and set method (pressure-sensitive vs. wet-set) on the label — setting your flooring too early or too late is the single most common glue-down install mistake.
- 4Roll the finished floor with a floor roller to fully seat it and push out trapped air.
- 5Hold off on heavy furniture and appliances until the adhesive has fully cured per the label’s cure schedule.

FAQ
Do I need a primer before using Romus Romus PVC Cold-Weld Seam Sealer (44 g)?
On bare or porous concrete, yes — priming first lets the adhesive bond evenly instead of soaking in unevenly. On plywood or an already-sealed subfloor, a primer usually isn’t required. Check our Adhesives & Primers page for the matching primer.
Pressure-sensitive or wet-set — which method should I use?
Most modern flooring adhesives, including this one, can be used either way. Pressure-sensitive means you let the glue flash off until it’s tacky/clear before setting the flooring — more forgiving for DIY. Wet-set means you set the flooring directly into the wet adhesive — faster, but less room for repositioning. Follow the open-time window on the pail either way.
