Using fine-grit sandpaper with a 180-220 grit, you can make a pass over the entire surface. You shouldn’t sand too deeply since you are not going to remove all the finish. Just grind the medium you want to repaint until it’s smooth and no longer slick. After the process is complete, wipe the surface with a tack cloth to pick up any sanding dust from the medium.

You can apply a bonding primer on the surface that needs to be repainted to prevent peeling or chipping during the drying or curing process. The bonding primer is formulated to stick to any glossy or other mediums that are hard to paint. It would be best if you coated this over the antique oil-based undercoat so that you get the optimal paint adherence.

You can use both oil-based and water-based bonding primers. Apply at least two coats rather than one and let it try to touch according to the product directions. To check if the medium you have coated is adequately primed, you should look out for the former paint color, stains, or other surface imperfections. If they are not visible, you have painted the primer correctly and adequately.

You should apply at least two layers of the high-quality water-based latex or acrylic paint over the surface you have earlier primed to allow ample drying between coats. You could refer to the product labeling to get the right directions. The paint can be applied using any brush, roller, or paint sprayer. It all depends on the budget you have or the tool available to you.

If the paint surface belongs to any exterior item, you could utilize both interior and exterior paints as they are more resistant to rot and extreme weather. You should select a complementary color and a semi-gloss sheen to accentuate the details on the trim if you are painting any molding or other decoration.
