- Subfloor
- Concrete
- Outdoor
- Wood
- Metal
- Heavy duty
The go-to heavy-duty construction adhesive when you need maximum strength and a bond that survives moisture and cold.
Pros
- Very high bond strength that works on nearly any material including concrete, treated wood, and metal
- Cures even in cold and damp conditions, so it holds up outdoors and in unheated spaces
- Paintable and low-odor with no harsh solvent smell during application
Cons
- Polyurethane foams and expands slightly as it cures, so joints need clamping or bracing
- Cleanup requires mineral spirits, not water, and it stains skin and clothing badly
- Opened cartridges tend to cure solid in the nozzle, wasting product if not resealed carefully
