SureCoat Systems’ Wood Restorer was designed to safely clean and restore the natural beauty of exterior wood surfaces, decks, and shake roofs. Wood Restorer can be used on cedar, redwood and other types of wood, but will not bring back natural wood color to pressure-treated green lumber. SureCoat Systems wood restorer is a low VOC, water-based, environmentally friendly, biodegradable liquid that easily removes mill glaze, dirt and general weathering; including mill glaze on new decking.
