I appreciate that it is rated to be applied over sound paint. Other brands do not recommend that and state you have to have clean bare cement. Never had a failure in many years. Review: Excellent product for exterior stucco! - I've been using the Larsen brand for decades now and it's by far the best concrete/stucco bonding agent on the market. I've used this product over concrete brick as well as existing finish coat plaster for many different exterior projects. Larsen also makes an "interior" bonding agent for gypsum plaster. Make sure you use the Larsen brand for any of your exterior/interior projects! ## Features - Interior/exterior - Size : quart - Concrete bonding agent - Bonds new concrete, stucco, tile setting beds and terrazzo to any structurally sound surface - Also used for bonding setting beds for ceramic tile, bonding portland cement plaster and stucco mixes, and to bond to surfaces such as brick, block, tile, marble, metal, glass block, soundly adhered paint and silicone ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.5 out of 5 stars 66 Reviews | ## Images ![Larsen Products WCQ06 "Weld Crete" Concrete Bonding Agent, Quart - Image 1](https://m.media-amazon.com/images/I/71iNqTRKbgL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ My favorite *by B***. on July 24, 2026* This has always been my go to bonder for stucco repair.
