Can I use regular DAP caulking rather than the acoustic type? What benefit do I get by using the $6 or $7-a-tube stuff? What pitfalls will I encounter by using DAP or regualr window-sealer type of caulking??

Thanks For The Advise -

Regular caulk shrinks and hardens.

Acoustical caulk can be found at most building supply companies.

My supplier sells it for $4.51 a bottle and it works

it stays pliable. will not crack or harden. as Aaron said

Which is #1

If you haven't done so, read the sticky at the top...

Has some good info...

just got 20 tubes of sheetrock brand acoustical sealant yesterday for $4.66 /tube + tax from Capitol Acoustics here in Atlanta, but you can probably order from their site www.capmat.com if you can't find something in your area.

It really doesn't seem that much more expensive, remember these are the BIG tubes (29 oz.), not those regular tubes (10 oz.) so you're basicly getting 3 times as much as you might think. It might work out to about the same cost anyway.

Actually, the only kind of caulk that might be able to "keep up with" acoustic stuff is the GE Silicon II, which runs around $4.50 a tube for 10 oz - so for the same price you get almost 3 TIMES as much, and it actually WORKS. The only thing you're out is a bit of legwork; and since you'll be using a TON of the stuff, the price difference alone will buy you a new toy or two for the finished studio... Steve

Hey Brad I live in the Philly area. About 2 hours from you. If you can't find anything close to home, there's an 84 Lumber in Frazer, pa that stocks OSI sc-175 acoustic sealant. It's $4.49 a tube. If your not familiar with Philly area... Frazer is 10 minutes south of the King of Prussia turnpike exit on 202 south. If you need more info... let me know.

Thanks All for your help. Once again, I learned QUITE a bit.

Thanks!!

Wow, that's really odd. In canada, Mono acounstical sealant is cheaper than regular caulking. I got it for 1.89 canadian at my local Canadian Tire.

Is that for the 10 oz tubes? I've yet to see any acoustic caulk in the US that's not 29-32 oz tubes... Steve

If 10 ounce is the small standard size, then yes.

Yeah, the "homeowner" size is 10 oz, the construction size is anywhere from 29 to 32 oz, depending on the density of the material. That price puts it in line with the big contractor tubes... Steve
