Black BioSeal 100% Silicone Sealant Caulk General Purpose, Waterproof and No Odor 10.1 Ounce Cartridge -Black (1)

Works well for boat. Fills in holes and seals well great value. Has a slight smell but is not bad. Easy to put on with a basic caulk gun.

Very smooth, easy to apply caulk. A little thinner than silicone, but hold shape perfect.

Works very well, and dried nicely. Although in the description, it said odorless. Its definitely not odorless. Now im wandering how long the smell will last. Because ive used it for my most recent vivarium build. Hopefully the smell dissipates soon.

I needed black silicone caulk for a shower. Most of what I could find from big box stores in black was for doors and windows and not fully mildew/mold resistant. So I gave this a try. The stuff is just too tacky and messy. Can’t get a clean bead and you can’t use a wet finger to smooth it. The new bead line often pulls away when finishing the line from the caulk gun because it’s so tacky. When trying to smooth the line, it smears terribly and it’s an absolute mess to clean up. I have to wait for it to cure before scraping it out since it’ll just make more of a mess. Avoid.

The product applies nicely, fills large voids where needed
