Sashco 15020 Sealant, Gray, 4 to 5 Days Curing, 40 to 90 deg F, 10.5 oz, Cartridge (Pack of 12)

Forget the concrete powder, mix bucket and big trowel. Just squeeze in Mor-Flexx to repair crumbly mortar, cracked stucco or textured walls. It's simple, it's fast, it works. Mor-Flexx may look like mortar and stucco but it stretches like rubber, staying elastic year after year. Mor-Flexx cleans up easily with water. No extra chemicals needed. It's paintable so you can match the color to your surface and its texture mimics that of real mortar and stucco.
