Unfinished redwood will begin to peel. This is especially true of redwood siding, which is susceptible to peeling from excessive precipitation, extreme weather and sunlight. When redwood siding begins to peel, it is a sign that you need to sand the redwood to remove the peeling and restore the wood. Apply a wood finish to the siding once you've finished this process to prevent the redwood from peeling again.
Sand the peeling areas of redwood siding with a coarse grit. Sand along the grain until you remove all of the peeling areas.
Sand the peeling areas of redwood siding with a fine grit until the wood is completely smooth and free of splinters. This will help it blend with the unpeeled redwood siding. Smaller areas are easily sanded with an oscillating tool and a coarse sanding head.
Paint the entire wall of siding with an oil-based wood sealer. Apply as much sealant as it takes until the wood soaks up the sealant but still leaves a thin layer on top. This will prevent the wood from absorbing too much moisture and peeling again.
Paint the spots you sanded with wood primer if the siding was originally painted. The wood primer will help prepare the siding for repainting. Let it dry completely before repainting the sanded areas with two coats of latex paint to blend those areas in with the rest of the siding.
