- Subfloor
- Concrete
- Outdoor
- Wood
- Metal
- Heavy duty
A polyurethane construction adhesive for heavy-duty bonds on subfloor, concrete, treated wood, and metal, indoors or out. It reaches very high strength, cures even in cold and damp, and stays paintable. Downsides: it foams and expands while setting, so joints need clamping, and cleanup takes mineral spirits, not water.
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
