The Thompson's WaterSeal 12 oz. Clear Multi-Surface Waterproofer is an aerosol that is ideal for waterproofing small outdoor projects, such as terra cotta planters, birdhouses and mailbox posts. It helps to prevent water damage to wood, brick, concrete and other types of masonry surfaces. It dries clear, allowing wood to gray naturally and is dry to the touch within 24 hours.
