Has anyone used acoustical sealant from DAP, Titebond or OSI or Liquid Nails?

| Posted in Green Products and Materials on

Hi, I have a concrete pour scheduled today for my footings and stem walls (vented crawlspace foundation) and that means I have a framing crew starting the sub floor system early next week. 

I plan on air sealing the the mud sill to the stem walls using a combination of sill sealer and acoustical sealant, then using the same approach to seal the bottom plate to my subfloor system. This is a spec house build that will be certified 4 star built green, so the budget is a bit tight. 

I have been researching the types of acoustical sealant that’s most commonly used for this application and found the Tremco Acoustical/Curtainwall Sealant, Tremco TremPro JS 773, and Pro Clima Contega HF seem to be the usual suspects. 

I have seen a Matt Risinger BUILD show episode where he is using DAP E90 as the acoustical sealant on his bottom plate along with the sill sealer (same approach I’m planning to use. 

Does anyone have experience with any of these lower cost acoustical sealant products made by vendors that are available from Home Depot, Lowe’s and Amazon? 

I realize the Tremco stuff is likely the best but I would like to save some money if I can get a product that will do the job for my application. 

This is a vented crawlspace so mud sill sealant is to minimize air flow into the insulated floor system.

The alternative contenders for sealant are: 

Titebond Acoustical Sealant ($7.99 per 28oz tube)
Liquid Nails Acoustical Sealant ($5 per 28oz tube
DAP Soundblock E90 (5.99 per 28oz tube)
OSI SC175 ($5.98 per 28oz tube)

Tremco Acoustical/Curtainwall Sealant ($15 per 28oz tube)
Tremco TremPro JS 773 ($8 per $20oz sausage)
