Sweep the area free of dirt, dust and debris. Scrub ground in dirt with Airport Grade™ Multi-Purpose Cleaner. Prime the area you are repairing with Airport Grade™ Oil Spot Primer (included inside the pail). On rough surfaces, the primer should be scrubbed into the damaged area with a stiff brush to wet the entire surface. The primer should become tacky before the Depression Filler is applied.

Repairing Depressions

Apply Depression Filler to the depression in the 6 mm to 12 mm (1/4" to 1/2") thicknesses with tamper or drive over patch several times to fully compact. You can not over compact. If patch seems soft it needs more compaction. Depression Filler instantly allows foot and car traffic with no drying time.

Repairing Cracks and Expansion Joints

Remove dust, dirt and debris by sweeping out the damaged area. Brush the primer into the damaged area ensuring the entire surface has been primed. Compact Depression Filler in 5cm (2”) increments. Depression Filler should be leveled and ready for use after heavy compression. Depression Filler can be sealed 90 days after the repair.
