Remove all movable objects from the concrete floor, and sweep up dirt, dust and debris. Use a shop vacuum to more thoroughly suck up particles.

Open the cap on your garden sprayer and pour in concrete degreaser. Replace the cap and pump the sprayer to build pressure. Hold the garden sprayer’s wand 7 to 9 inches away from the concrete, and spray an even coating of degreaser onto the surface.

Work a nylon brush in short circular motions over the degreaser after it has set for 30 minutes to more thoroughly break up grease, oil and other stains.
- 4
Spray the concrete with a garden hose to clear away the concrete degreaser. Allow the surface to completely dry before continuing.
- 5
Carefully follow the instructions on the side of the self-leveling compound to mix the compound with water in a large bucket or similar container.

Immediately apply the compound on the low spots on the concrete floor and smooth down with the flat trowel. Do not pack the compound down; it will begin to spread and level as it cures. Wait 48 hours before driving or walking on the surface to allow the compound to fully cure.
