Frequently Asked Questions
1. What should I do if my construction adhesive fails to bond or starts peeling?
Remove the failed glue down to the bare substrate, clean off all dust, grease, and moisture, and re-apply using the proper formula. Most bond failures stem from un-prepped surfaces, rushed cure times, or applying the wrong adhesive for the specific material or climate.
2. Why is my construction adhesive still soft or un-cured after 24 hours?
Slow curing usually results from excessive moisture, sub-freezing temperatures, poor ventilation, or applying too thick of a bead. To fix it, increase jobsite airflow, raise ambient temperatures if possible, and ensure non-porous substrates aren’t completely sealing off air from the inner glue line.
3. How do I safely clean up fresh squeeze-out or dried adhesive from surfaces and tools?
Wipe wet squeeze-out immediately with a dry rag and mineral spirits. For dried, rock-hard adhesive, soften the bond line with a heat gun or hairdryer, then carefully scrape it away at a flat angle using a putty knife or specialized solvent remover.
4. What happens if an adhesive melts my rigid foam or plastic panels, and how do I fix it?
Aggressive solvents in heavy-duty adhesives eat away at polystyrene foam and plastic tub surrounds. Scrape out the melted area, patch or replace the ruined section, and re-bond using a solvent-free or specialized formula like Leech F-13® that won’t degrade sensitive substrates.
5. How do I re-bond a joint that failed due to wet lumber or freezing temperatures?
Scrape off the failed, frozen glue, wipe away standing frost or surface water, and switch to an all-weather solvent formula. Water-based glues freeze and fail in cold weather, whereas heavy-duty solvent adhesives like Leech F-26® are engineered to grab damp substrates and cure in temperatures as low as 0°F.
