How Long Before You Paint Body Filler on Car?

Body filler is a type of automotive repair material that is used to fill in dents, scratches, and other imperfections in the body of a car. It is a two-part compound that consists of a resin and a hardener. When the two parts are mixed together, they create a chemical reaction that causes the filler to harden. The curing time of body filler can vary depending on the type of filler and the temperature of the environment, but it typically takes between 20 and 30 minutes for the filler to fully harden.

When Can You Paint Body Filler?

Once the body filler has hardened, it is important to wait at least 24 hours before painting it. This will give the filler time to fully cure and to ensure that it is properly adhered to the surface of the car. Painting the filler too soon can cause the paint to crack or peel, and it can also lead to the filler failing.

If you are using a two-part epoxy primer, you can apply it to the body filler after it has hardened for 24 hours. The epoxy primer will help to seal the filler and to provide a smooth surface for the paint. Once the epoxy primer has dried, you can apply the paint to the body filler.

If you are using a one-part primer, you can apply it to the body filler after it has hardened for 48 hours. The one-part primer will help to seal the filler and to provide a smooth surface for the paint. Once the one-part primer has dried, you can apply the paint to the body filler.

Tips for Painting Body Filler

Here are a few tips for painting body filler:

Make sure that the body filler has fully hardened before painting it.
Use a two-part epoxy primer or a one-part primer to seal the body filler and to provide a smooth surface for the paint.
Apply the paint to the body filler in thin, even coats.
Allow the paint to dry completely before applying additional coats.

By following these tips, you can ensure that your paint job will look great and will last for years to come.
