Concrete Repair

[BrandonV]

I have a few outdoor areas with small divots that I want to fill using a concrete repair product. I prefer to use a high-quality product (epoxy or similar).

Initially, I bought a two-part epoxy product from Rust-Oleum, which you can find here:

Rust-Oleum Concrete Patch & Repair

Easily repair concrete cracks and holes with Rust-Oleum® EPOXYSHIELD® Concrete Patch & Repair. This two-part, industrial-strength epoxy permanently bonds concrete, won’t shrink or crack and creates an extremely hard surface that is stronger than concrete.

www.rustoleum.com

However, the product label states that "exterior applications must be coated with a solid color exterior coating." Is this warning only for people who plan to coat their concrete afterward, or is there a downside to using this product outdoors for general repairs?

I'm open to any suggestions for better products, as I want to avoid purchasing an excessive amount for just a couple of areas.

Probably not UV stable.

In general, I think you are better off using a repair product with similar properties to the substrate, which in your case would be a cementitious product. You will also get a better color and texture match. I'd recommend Silpro TDQ or Ardex CD. As with any repair, surface prep is the key so follow the mfg's directions.

Ardex is by far the best option in my opinion
