Exterior sealers such as enamels, lacquers and stains are some products for exterior wood protection. Water sealers, water repellent wood preservatives and wood toners provide wood surface protection while enhancing the wood's structure.
Wood enamels form a thick layer of film over wood exteriors to cover defects. They are water repellent and come in a variety of colors. Lacquers are plain enamels without pigments that retain the natural wood appearance while protecting wood against ultraviolet radiation and ageing.
Stains are mildly pigmented wood finishes that retain the wood's appearance but protect it from weather influences and water damage. Stains protect exterior wood while letting it breathe.
