slant fin baseboard covers - rusting and paint peeling off in strips in bathroom
Will spraying with a (rustoleum) rust inhibitor prevent new metal slant fin baseboard covers in the bathroom from rusting, or is it a waste of time? I switched this time to "High Output" instead of the lighter ones originally there that rusted like crazy.
Besides custom wood ones, are there other covers in materials that don't rust (I thought I saw on This Old House that there are ones in plastic/pvc? that have grates, but can't find any except metal Slant Fin).
First the metal covers are part of the "radiator" in baseboard radiator, so putting wood or plastic covers over the elements will insulate the element from the room that you want to heat. The direct opposite of what you are looking for. Second, the coating or paint on the covers for baseboard radiators for the last 40 years or so is only a primer and not a heavier finish coat as most people think. So when they are installed in a small high humidity room, such as a bathroom, they will tend to rust right out of the box, so to speak. Now add in the added problem of placement of the baseboard in the bathroom and the horror -according to women- of the male gender missing the throne and possibly spraying the baseboard occasionally and it will rust even faster. The covers that you already have should be removable without removing the elements so take them off, wire brush them so most of the rust and primer is gone. Then wipe them down with paint or laquer thinner and make sure they are good and dry. Rustoleum makes a good primer. Use a spray can and paint both the inside and outside surfaces and let dry for at least 8 hours. Then pick out the Rustoleum color in a finish coat with the same base chemicals in it and respray both inside and outside surfaces and let dry another 4-6 hours and recoat with your finish coat again. One primer and two finish coats and you should be good for a few years anyway.
