How to Paint Over Enamel Oil-Based Paint

There are some rules in painting with regards to oil-based and latex paints. Since latex paint is water based, you should not paint over it with enamel or oil-based paint. You can use latex paint to cover enamel or oil-based paint. Proper preparation needs to be followed when painting over enamel or oil-based paint. Preparing the surface to accept the paint will assure a successful job, both in the way it looks and how long it lasts.

Sandpaper (100 to 150 grit)
Rag
Primer
4-inch paint brush
Drop cloths or plastic
Painter's tape
Oil-based or latex paint

Instructions

- 1
  Lay a drop cloth or plastic on the floor to protect it from paint splatter or sanding debris. Use painter's tape to protect any area that you do not want painted.
- 2
  Sand the area to be painted with 100 to 150 grit sandpaper. Ensure that any rough spots and paint flakes are removed and the entire area is made smooth. The smoother the surface the better the job will turn out.
- 3
  Clean the area with a rag and warm water. This will ensure that dust and debris will not be trapped in the paint. Allow the surface to dry completely before applying the primer coat.
- 4
  Use a good quality primer and a 4-inch paint brush to apply a base coat. The primer is a bonding agent that will help the final coat of paint adhere to the surface. Allow the primer coat to dry per the instructions on the can.
- 5
  Apply the final coat of paint with a 4-inch paint brush using long, even strokes. Ensure that the entire area is evenly covered with the paint. With the use of a good primer, a second coat should not be necessary.
