Unfinished redwood will begin to peel. This is particularly true of redwood siding, which can be susceptible to peeling out of excessive precipitation, extreme weather and sun. When redwood siding starts to peel, it’s a indication you want to sand the redwood to eliminate the peeling and then revive the wood. Apply a wood finish to the siding once you’ve completed this procedure to prevent the redwood from peeling again.
Sand the peeling areas of redwood siding with a rough grit. Sand across the grain until you eliminate all of the peeling areas.
Sand the peeling areas of redwood siding with a fine grit until the wood is totally smooth and free of splinters. This can allow it to mix with the unpeeled redwood siding. Smaller areas are easily coated with an oscillating tool plus a rough sanding head.
Paint the whole wall of siding having an abysmal wood sealer. Apply as much sealant as it takes until the wood soaks up the sealant but nevertheless leaves a thin coating on top. This will prevent the wood from absorbing too much rust and peeling again.
Paint the spots that you sanded with wood primer if the siding was initially painted. The wood primer can help prepare the siding for repainting. Let it dry completely before repainting the coated areas with two layers of latex paint to blend the areas in with the rest of the siding.
