Thompson’s has introduced waterproofing stain in an aerosol dispenser. The 11.75-ounce WaterSeal aerosol combines exterior wood stain with sealer and offers UV protection and mildew resistance, according to the company. The five available colors—including shades of brown, gold, and red—match the full-size WaterSeal line. The small package is designed for matching deck-stain colors on railings, lattice, plant boxes, and wooden furniture. It’s quick, the company says, and there’s no cleanup involved. The aerosols will retail for between $9 and $10. Thompson’s WaterSeal, 800.367.6297, thompsonswaterseal.com
