Rust Oleum Fine Crack Repair Mortar

The Rust Oleum Fine Crack Repair Mortar is a two-part, solvent-free epoxy filler designed to repair fine cracks in concrete floors, suitable for cracks up to 3mm wide. Supplied in a 500ml pack, this non-shrink liquid mortar offers a practical solution for restoring structural integrity to cracked concrete surfaces. Its solvent-free formulation makes it suitable for use in enclosed or poorly ventilated environments where solvent-based products may be unsuitable. A single 500ml pack provides approximately 25 linear metres of coverage on a crack measuring 2mm wide and 5mm deep, though actual coverage will vary depending on crack dimensions. With a dry time of just 3–4 hours, it minimises downtime on site — making it a practical choice for contractors, floor layers, and facilities maintenance teams.
