## Questions & Answers

**Q: I'm looking to attach some tin tiles to sheetrock. Think this will work?**
A: I think that you would have better results using the following item: "Dap 27450 Beats The Nail All-Purpose Construction Adhesive 10.3-Ounce".  Make sure that you remove any oily film that may be on the tin before applying the construction adhesive.

**Q: Can this be used to install wood stove door gaskets?**
A: YES!

**Q: Is the item waterproof? Can it be used outside for repairs in all weather conditions?**
A: Yes it is waterproof.
I used it around my flue pipe on the roof.
Stuff works great. I would do 2 layers instead of one.

**Q: Has anyone had success with this product without fire curing?  Manufacturer says it must be fire cured but I need a fire seal of 2000F+ but can't fire**
A: I used this to seal the storm collar and flashing around my class A chimney penetrating through my roof.  That installation definitely was not fire-cured, and has held up extremely well.  It does cure very hard, but has performed well for my application.  I check, the seals when I clean my chimney every year, and 11-years in all is still well.
