If the concrete surface with the Quikrete Vinyl Concrete Patcher is soiled with oil and grime, wash the surface with a ready-to-use degreasing solution by mixing ½ cup of degreasing solution and 1 gallon of warm water in a bucket and applying the mixture with a scrub brush to remove the buildup.

Quikrete Vinyl Concrete Patcher is a fast-drying repair material for concrete surfaces, including driveways, walls and walkways. The substance spreads easily and consists of fine sand, vinyl resin and Portland cement. Quikrete Vinyl Concrete Patcher is available in two colors, gray and white, but also accepts latex and oil paints if you need the substance in another color. You must let the concrete patch dry completely before you sand it or apply paint.
Let the Quikrete Vinyl Concrete Patcher dry for seven days if you are planning on applying latex paint to the surface and the patching compound was recently placed on the concrete surface.
If you're planning to use an oil-based paint, let the patching compound dry for 28 days.
Sweep or wipe the concrete surface with a broom or soft cloth to remove any dust and debris from the patching compound. Wear work gloves to keep your hands clean.
Sand the Quikrete Vinyl Concrete Patcher and the area surrounding the compound with a 200-grit or higher piece of sandpaper to smooth out the surface. Change sandpaper frequently, and then wipe the surface with a soft rag or towel to remove any loose sanding dust and dirt.
Fill a paint tray with latex or oil-based exterior primer. Use a paint roller or brush to apply the primer to the concrete surface. Let the primer dry according to the recommended time on the product's container. The primer helps seal the patching compound and prepare the substance for paint.
