OSI SC175 Draft & Acoustical Sound Sealant, 28 fl oz, Cartridge

This sealant was essential for my soundproofing project, effectively sealing gaps to significantly reduce noise transmission between rooms. I found it surprisingly easy to apply and clean up, and I love that it remains flexible to maintain a tight seal over time.

Used two tubes for a remodel and worked well.

I've ordered two tubes of this stuff, from two different vendors, and both of the tubes arrived damaged. The first one had a bent nozzle, canted severely in order to fit into the shipping package. The caulk was oozing at the nozzle/tube connection. What are the odds that another tube would be similarly damaged, I thought, and ordered a replacement. I was sorta right and sorta wrong: this nozzle was jammed deeply into the tube, with just the tip poking out, like a turtle's head inside of its shell. I give up. (Edit: The vendor "Great Household" did not give me a postage-paid label; sending it back would cost me $14, more than what I paid for the item. They have not responded to an email. So, effectively, the defective item is nonreturnable.)

Toolability is quite low, like other acoustic sealants. Never dries in the middle. On purpose. This is how it stays super flexible.

Thanks

Had a lot of pockets to fill in my vocal booth. This was perfect

The product is high quality but hard to work with. Like many others I experienced some nozzle damage in shipping but the worst part is trying to squeeze this stuff out of the tube with a standard caulking gun. Even Popeye would struggle.

Room is really sound proof. It works well.

The product seems good but no response from the manufacturer when we tried to return unopened tubes. Would not recommend. Amazon was even worse. Local is always best.
