Painting a cooler requires applying and sealing paint. Before painting a cooler with acrylic or oil-based paints, sand and prime the cooler first. Due to lengthy drying times, this project takes two to three days to complete.Continue Reading
Use a coarse-grit sandpaper to remove the finish and any texture from the cooler. Finish sanding with a fine-grit paper to smooth the surface. If you want to fill in deep indentations that cannot be removed by sanding, fill them with spackle.
Wash and dry the cooler to remove any dust. If you do not want to paint certain areas of the cooler, cover those parts with masking tape and plastic wrap. Spray on a plastic primer, such as Krylon Fusion, to the outside of the cooler.
Once the primer is dry, paint the cooler with acrylic paint. Let the base coats of paint dry, and then add the details. Acrylic- or oil-based paint pens make painting details by hand easy. You can also use a stencil to create a pattern or add a team logo.
After the paint is dry, apply Mod Podge with a foam brush, or spray on another acrylic sealant. Add a few coats of sealant, and let it cure for at least 24 hours.
