How to Remove Deck Waterproofing From Siding on the House

Remove deck waterproofing from house siding.

Deck waterproofing brightens and seals the wood on a deck, protecting the deck from moisture, mildew and fading. When applying deck waterproofing, it is common to accidentally transfer the sealer onto other nearby surfaces, such as the house siding. The sealer can ruin the appearance of the siding, leaving unsightly stains. Fortunately, deck waterproofing can be stripped from siding with certain products. Test the products on an inconspicuous area of the siding, before attempting to remove the stains.

Things You'll Need

• Deck sealer remover
• Polyester brush
• Stiff bristle brush
• Garden hose
• Clean towel

Instructions

1. Purchase deck sealer remover from a home improvement store. Dip a polyester brush into the deck sealer remover.

2. Apply a generous amount of the sealer remover over the stained siding, using the polyester brush. Allow the sealer remover to set on the stained siding for 30 minutes.

3. Scrub the siding with a stiff bristle brush, to remove the deck waterproofing. Continue scrubbing until the stain is completely removed.

4. Rinse the siding with water from a garden hose, to remove any remaining residue. Dry the siding with a clean towel.

Tips & Warnings

• Use a sponge or cloth, instead of the stiff bristle brush.
