About this item
Product details
Mor-Flexx by Sashco Sealants is a premium acrylic latex caulk designed for both indoor and outdoor use, making it ideal for concrete and mortar repair caulk needs. Unlike traditional mortar, stucco, and grout repair products that dry hard and brittle, Mor-Flexx stretches and flexes to create a long-lasting, waterproof seal that resists cracking. The gray, sandy texture blends seamlessly with mortar and is paintable, allowing repairs to virtually disappear. This versatile mortar repair caulk is perfect for fixing mortar, stucco, artificial stucco, EIFS, concrete foundation sidewalls, basement floors, and even textured walls and ceilings. It adheres strongly to wood, concrete, brick, stone, block, and other masonry surfaces, ensuring reliable performance. The 10.5 oz. cartridge is easy to apply and suitable for a wide range of masonry and cement repair projects. Mor-Flexx is an excellent choice for anyone looking for a durable, elastomeric masonry caulk that delivers professional results. Please note: This product contains a chemical known to the State of California to cause cancer. Always follow safety instructions when using Mor-Flexx concrete and mortar repair caulk.

Works great!
This worked great on our front porch where we removed some posts that left holes where they had been bolted in.
