What Customers Are Saying

Customers overwhelmingly praise this exterior patching compound for exceptional durability, ease of application, and versatility across diverse surfaces including fiber cement, vinyl, wood, stucco, and metal. Reviewers consistently describe it as creamy, ready-to-use, and simple to spread and smooth with minimal sanding. Many note repairs have held up for years through storms and weathering where previous products failed. The quick drying time allows painting the same day, and users report achieving smooth finishes by dampening surfaces after application. A few mention storage consistency issues, but most consider it a reliable, high-performance solution.

Great for using in in-ground pools

Would Recommend

Worked very well for patching cracks in our in-ground pool. Took only a few hours to dry after being applied and we were able to fill the pool the next day.

Zero adhesion

Would Not Recommend

I could not get it to stick to wood or cementitious siding. I felt like Play-Doh coming out of the can. Stirred the product with tongue depressor - it was consistent throughout the container.

Great exterior patch compound

Would Recommend

This product worked very well on my fascia and window trim patching. It hasn't been out there long, and thus I can's speak to the longevity. But it sure is easier to use than Bondo or other mixing compounds that have a very short window of time that you can work the product.
