ight want to take the radiator out of the home and have it professionally sand blasted which might be needed to promote adhesion and if there are multiple coats of paint already on the radiator. The other reason to sandblast the surface is because the radiator has a factory applied paint already on that cannot be removed by mechanically grinding or sanding the existing surface. If sandblasting is not an option, sand all the existing paint that will come off and create a rough surface so the paint has something to stick to or “bite into”. Painting a radiator can be time consuming, messy and also difficult while surface preparation is important, choosing the paint, color and application method needs to be considered.
After removing the loose paint, grime, dust, oil or other surface contaminants getting down to bare metal, choose a color that is available in aerosol cans or quarts and states the paint is heat resistant. One or two light coats are needed as per the instructions on the back of the can or per the paint manufacturer’s instructions. Since this paint is usually a solvent based paint, china bristle brushes should be used which usually have a wooden handle. Open windows and provide proper ventilation during application and drying. Choosing a color can be very easy from a paint manufacturer who offers multiple colors for radiators. Most like to match the décor of the room the radiator is located in. Also keep in mind that if you are painting the radiator that is in place, mask off where you don’t want the paint to stick to in case of drips or overspray.
