Common Questions
Does the black caulk dry to a glossy finish or is it more like a dull rubber?
I wouldn't describe it as dull, but it still has a dark matte color.
Will this be able to bond to rubber?
I let it dry and didn't know what rubber was, but everything else I did, it stuck like paint. My clothes, STAINLESS railings, fiberglass cabin, teak of course, cork fishing rod handle, my leather wallet.
Can it be used as caulking for tile?
I didn't buy it for that use, but it works like glue and is easy to stick together.
Will an opened tube be usable for a few days, or does it quickly harden in the tube after opening?
It will remain usable for at least a week if you seal the tip well.
Is it really self leveling?
I don't use that much in one spot.
