Repair Peeling Paint on Fascia Board




When paint peels on wood, one needs to find the fault that is causing the surface to peel. There are some common causes such as bad priming and under-coating, or the wood gets wet and fungal growth forms under the topcoat. Whatever the cause it’s important to fix the problem and get down to a sound surface.

Begin the repair by scraping away the peeling paint and have a look at the surface.

In cases where the wood is sound, but may not have been primed or undercoated correctly, give it a basic sanding to smooth the surface and re-paint the surface. Feather the edges of the remaining paint so that the repair won’t be noticeable. You’ll now have a sound surface on which to apply the finishing paint coats.

If there’s a fungal growth visible when you scrape off the peeling paint, use a bleach solution, mixed 2 parts water to one part bleach, to clean off the surface and to kill off the fungus. Two applications are vital. The first kills the top sections of the fungus and the second application kills the roots so that it won’t re-appear.

Fill any holes. Once it has set, sand the filler using 100 grit sandpaper. Follow the manufacturers instructions for setting time, but don’t let the filler get too hard before you start sanding.

Once you have a sound surface to work on, the painting can be done.

Begin the finishing with a coat of wood primer. Spot prime the areas of bare wood only, it’s not necessary to prime the entire piece. When the primer is dry give the area a very light sanding with a 150 to 220 grit sandpaper to remove any roughness and wipe down with a damp cloth to remove all the dust. Follow with an under-coat, once again just over the area that is being repaired . Once the undercoat is dry, sand the entire piece lightly with 220 grit paper, wipe off the dust with a damp cloth and finish with two top-coats.
