Customers overwhelmingly praise this mortar caulk for seamlessly blending with existing mortar and stucco, often appearing indistinguishable after drying. Reviewers consistently highlight its ease of application, smooth texture, and water-based cleanup. Many report it holds up well under weather exposure without cracking, remaining flexible over time. A few mention difficulty extruding from the tube or slight color variations on older mortar, but the vast majority consider it a reliable, long-lasting repair solution for both DIYers and professionals.

Excellent caulk for filling cracks in brick walls.

 Would Recommend

I bought the product to fill crack in brick. The caulk went on smoothly and penetrated cracks. The texture matched the brick fairly well. After painting it was hard to identify the filled cracks.
