If you're looking to give a surface its first coat of paint, you'll need primer. This will help the paint to bond with the surface, making it absorb less and therefore saving you money. Undercoat is used for surfaces that have been painted before but still require a smooth finish. Shop JDS for a wide range of exterior primers and undercoats.
