Sashco Mor-Flexx Gray Cartridge Mortar Sealant

Unlike other mortar, stucco, and grout repair products that dry hard, brittle, and soon recrack, Mor-flexx stretches and flexes for a long-lasting seal. The sandy texture and color of mortar is paintable, so repairs can literally disappear. Use to repair mortar, stucco, artificial stucco, EIFS, concrete foundation sidewalls, and basement floors, even textured walls and ceilings. It adheres excellently to wood, concrete, brick, stone, block, and other masonry surfaces. 10.5 oz. cartridge.
