Sealing Bottom of Cabinet Saw: Foil Tape. Silicone, or Something Else?

White vinyl duct tape. Silicone caulk. Maybe even that spray foam that doesn’t
expand so much. That could be messy though.

I would probably use duct tape if there is room to apply it.
Doesn’t matter so much what it looks like. Only you will
know its there.

I used the foil tape, and didn’t worry too much about “crisp” corners. Like Ron said, this isn’t something someone will see. Mines been in there for over 4 years so far with no damage or problems.

Use a backer board or dowel and then add silicone.

I would use foil tape as much as possible. I like the spray foam for the tricky places, like to seal off the table top cavities and cabinet.

Try caulk backer rod…Inexpensive and is easy to use for many sealing tasks around the house. Comes in many sizes and compresses a lotto fit many applications. Tape and other things are sticky and hard to remove. https://www.dap.com/product_details.aspx?BrandID=4&SubcatID=1

Excellent. Turns out I have some backer rod already just waiting to be used.

-- Yeah, I'm probably over-thinking it. But that's my other hobby.

I got some backer rod from ACE hdwe one time. It was 1/4” and looked and worked like modeling clay. I can see that working well if the other doesn’t.

Thx Grandpa. I’m glad you mentioned it, as the stuff I have is more like 1/2.” I purchased it for renovation on the 1872 house we bought a little over a year ago. Anyway, it was too big for the purpose I needed it for -filling in a 1/4” gap -so if I can find the stuff you mentioned I’ll be killing two birds.

I think I’d use the puddy Gpa mentions or the silicone and then the foil back tape.

I have a large gab between my table saw cast iron top and the cabinet. I used Styrofoam to wedge in the gap and that really helped the HF Dust / Chip collector keep up with collecting the waste.

I have a few rolls of the foil tape and hadn’t thought about using that > Hmmmmm I’ll look at that tomorrow!! There’s also a few openings in the bottom of the cabinet I can use that for!!

Thanks and hope it works for you.
