To get the best results from repainting your siding, you need to make sure you do prepare your siding properly before you apply the first coat of paint. Here’s a guide to preparing your siding for repainting.
Inspect your siding, and look for signs of dry rot, warping and other problems that may be caused by moisture and temperature changes. While materials like vinyl and composite are resistant to such problems, you need to do this if you have wood siding. You may have to have repairs conducted by a siding professional depending on the extent of the problem.
Most types of paint works best on clean surfaces, so make sure the siding surface is free from dirt and grime. Vinyl and similar types of siding can be washed with a garden hose. Other types may require cleaning solutions and maybe a little bit of elbow grease. You can use a pressure washer for fast cleaning, but take care not to use the red nozzle as it may damage the surface. Always keep a six-inch clearance between nozzle and siding, and only use detergents designed for use on pressure washers. Always point the nozzle downwards to avoid forcing water into the siding gaps.
The areas around the siding must be protected during painting. Cover the surrounding landscaping and work areas with tarp. Apply painter’s tape to trim and other components to avoid painting over them. These covers also make it easier to clean up after you’re done painting.
The old paint layer might appear to be peeling, blistering or cracking. You need to scrape it off first and then use sandpaper to smooth out rough surfaces. If you’re repainting siding that was installed in the 1970s or earlier, there’s a chance that it may contain traces of lead. In which case, you need to consult with an exterior professional and have the paint tested. Once your siding is deemed safe for painting, start with a primer, let it dry, and apply the outer coat of paint.
