PVC Trim Welder comes in fast- and slow-curing formulations and laminate grade. The fast-dry’s five-minute open time means you can glue up an outside miter or other assembly and put it in place right away; the slow-dry’s 15- to 20-minute open time provides more flexibility when gluing long pieces. The laminate grade has a low viscosity so it will spread across the surface when two boards are placed one on top of the other. A 50-ml cartridge costs $13, a 220-ml $29.
