Preparing Your Surfaces

Clean and dry surface thoroughly. Scrub stained areas with an all-purpose cleaner to remove any residual stains. Remove all surface dirt, chalk and mildew. Tannin stained areas on wood do not need special surface preparations. For fire damaged areas, remove burned or severely charred areas to sound wood surface. Sand smooth. For mildew stains, this product will seal residual stains from old mildew, but will not resist active mildew growth. All active mildew must be removed from surfaces prior to application by scrubbing affected area with a commercial mildew remover or a solution of 1 part liquid chlorine bleach to 3 parts water. Rinse thoroughly. Wear protective goggles and rubber gloves to avoid chemical contact with skin or eyes.
