Roadware 10 Minute Concrete Mender 2 Gallon 80020
Roadware 10 Minute Conrcete Mender is a two-part polyurethane that penetrates deep into concrete to make permanent repairs. Nearly thin as water at less than 9cps, Concrete Mender actually injects itself into the matrix of the concrete and shores up the existing concrete as well as making the repair. Concrete Mender eliminates the bond-line as it Microdowels into the concrete.

Frequently Asked Questions:
Can I use this for vertical repairs?
Yes. When combined with sand, Concrete Mender can be troweled onto vertical surfaces for strong, non-sag repairs.
How is the bulk version mixed and applied?
Mix 1:1 by volume (A to B), blend with sand, and pour directly into the repair area. Work quickly—pot life is short.
What prep is needed before application?
Ensure the surface is clean, dry, and free of contaminants. Mechanical abrasion is recommended for proper adhesion.
