Thread: Need answer quick

Tweet

Down to the last few days and I need an answer to this quick. I'm stuck at home today no car so I have to use what I have here.

Finishing the last foam tombstone of the year and need to fill in some gaps. All I have here is Joint compound (the kind you use for monster mud), caulk and grout.

Color doesn't matter because I will be using dryloc to cover, if it will cover any of the above.

Suggestions on what would work best?

Joint compound because it will dry faster and you can sand it. Put more on it than you will need to fill the gap, it will shrink some when it drys. The grout will also work but I wouldn't use the caulk because you can't sand it to even out the gap like you can the Joint compound and grout.

Just blob in the joint compound to fill, then randomly slather on the excess over the whole tombstone to get a lot of texture and detail.

If the gaps are fairly large, use caulking...the reason i say that is, joint compound will dry and shrink and eventually will pop out of the hole or crack you are filling and it doesn't adhere well to foam at all. Caulk or silicone will provide a stickiness and tightly attach itself to the foam and you should be able to paint it when it eventually dries. Also, joint compound doesn't do well in the elements unless sealed properly.Problem is, caulk takes a little bit longer to dry completely than joint compound.
