No more replacing sealer and grout, or dealing with multiple repairs. Save time and money with Mor-Flexx. This flexible caulk is textured to blend in perfectly with mortar, stucco and concrete surfaces. It's paintable so you can get the right match for your unique project. Plus, it stays elastic over time, giving you more flexibility and durability than a standard silicone caulk, meaning you don't have to do the same work over and over again when surfaces more.

This ground sealer and concrete sealer fills gaps up to 3 inches wide, and it's paintable and made with a low-VOC formula for safe use indoors.
