Caulks and sealants are adhesive materials that fill and seal gaps and cracks to keep out water and air. Water-based acrylics can be painted, can be cleaned with water, and require less surface preparation than solvent- and silicone-based caulks and sealants. Water-based acrylic caulks and sealants have less of an odor than solvent- and silicone-based products. Solvent- and silicone-based caulks and sealants are generally more flexible than acrylics and can withstand more sunlight and temperature extremes. They require solvents to clean, are more difficult to remove than acrylics, and generally cannot be painted. Water-based acrylic caulks and sealants with added silicone offer a variety of features, depending on the specific formula.
Sashco manufactures caulks and sealants. The company, founded in 1936, is headquartered in Brighton, CO.

My favorite brand of caulk. It is thick enough that it doesn’t spurt out of a good caulk gun. It appears to stretch across the surface you are caulking. Read morePublished 9 days ago by James W. Head
If you need a caulk that stretches, this is it. Other than that, it works like any other one.Published 1 month ago by badazzps
Love it. Does not break away from surfaces like other caulks; leaving a crack. This solves the problem. Especially near moving parts of the house, like door trim. Read morePublished 1 month ago by Sphinxrb
seems to work ok will now more in fall when exterior walls move a littlePublished 1 month ago by Michael Bilyeu
It doesn't completely dry and that's why it easily attracts dirt that is almost impossible to clean off so I would definitely recommend that it be painted. Read morePublished 2 months ago by KimberMcC
