Common Questions
If this product isn't used within 24 hours after the seal is removed, will it go bad?
If you reseal it, put it in a ziplock and put it in the refrigerator, but take it out before the next use if it's very thick and hard to keep at room temperature.
I don't know if this will bond wood tomw, or if I should use the 5200.
No. But DP-8005 might.
Can this sealant be used to fill in the gaps between the tiles in the shower?
It can, and it is, but don't do it, it's permanent.
Will there be a flap down on the rubber pond liner? I want it to stay layer flat.
It says in the specifications that it remains flexible, so it should work, but you might have to apply some glue to the surface to give it a little more 'tooth'.
Does the product need a special gun or tool?
I was able to squeeze enough out by hand to complete my small project, but it was very difficult to do without an applicator.
