## Description

Black BioSeal 100% Silicone Sealant Caulk General Purpose, Waterproof and No Odor 10.1 Ounce Cartridge -Black (1): desertcart.com: Industrial & Scientific

Review: Excellent product, used in kitchen. - I bought this in black to seal between new countertops and the tiled backsplash I installed in my kitchen. I’ve done a lot of home renovation over the years and I was impressed with how this product worked. Very thick but easily workable. Dried to a matte black so it blended in with my black grout and countertops quite well. Clean up was easy with isopropyl alcohol. Normally I use the silicone sealers from the home improvement stores but I found this stuff was a lot easier to work with, especially the clean up end. It does give off an odor but gone once dried. I’ll be using it again in the future.
Review: Great product for boats - 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.
