Application & Cleanup

Ensure concrete is clean, dry, and at least 30 days cured. Mix equal parts of Components A and B thoroughly before use. Apply with a caulking gun or trowel to achieve full coverage. Clean tools immediately with mineral spirits or IPA before curing—cured epoxy is extremely difficult to remove.

Choose Mannington MR-715 (1 Gallon) for small to mid-sized stair tread installations requiring high bond strength, quick setup, and dependable epoxy durability.
