Description
Dunlop Ardit Crack Filler is a high strength, two-part hybrid polyurethane that repairs cracks and spalls in concrete almost instantly. With a viscosity similar to water, it flows deep into cracks that pastes and mortars can't reach, then cures harder than the surrounding concrete within an hour. Driveable repairs are possible in as little as 20 minutes, making it a genuine problem-solver for busy floors and driveways.
Where to use it
Suitable for indoor and outdoor concrete - garage floors, driveways, paths, warehouse slabs and patios. Because the two parts mix automatically through the nozzle, it is equally at home in a professional toolkit or a weekend repair kit.
How to use
Clean the crack thoroughly, removing dust, loose material and any moisture. Load the 254ml dual cartridge into a suitable applicator gun, attach the self-mixing nozzle and dispense directly into the crack until full. For wider spalls and larger repairs, blend in clean, dry bagged aggregate to bulk the fill. The repair sets stronger than concrete in about 1 hour and takes vehicle traffic after roughly 20 minutes.
Important notes
New concrete must be fully cured - at least 28 days old - before application. The water-thin consistency is designed for penetrating cracks, so dam or tape the ends of through-cracks where needed. Used nozzles cannot be reused once the product sets.
