Common Questions
Will it fill in the gap between the sheets of paper?
If the gap is very small, the material should be fine, as it is best suited for small surface nicks and scratches. To buff it in, I would use a light sealer, which is very tough and invisible.
Is it possible to use this for seams on Quartz counter tops?
No. The mfg. stresses laminate seams, such as Formica.
I'm wondering if it could be used to hide the counter top that I need to be over 13 feet.
It would do a great job of hiding the seam, I had a 16 crack across my white laminate countertop, someone had jumped up on it to sit and put a 16 crack in it.
Will the new countertops help prevent water damage at the miter joints?
Yes. It sealed a crack in my laminate and kept the water out.
Is it possible that it works with cast iron sink chips?
I didn't try it on a sink, but the results should be the same, a good repair, and the finish won't be the same, but maybe a nice clear coat after would give you a great finish.
