Outdoor wood
Exterior & UV-resistant systems
Explore Renner exterior systems designed for dimensional movement, weather exposure, and ultraviolet light.
Exterior wood is a system problem: design, drainage, species, preparation, application, and maintenance all affect coating life.
Use an exterior-rated schedule
Renner's exterior families are formulated for weather exposure and ultraviolet light. Interior clear coats are not substitutes. Select primers, sealers, and topcoats that are approved together for the intended exposure.
Color and protection are connected
Pigments and system design help protect wood from UV. Fully clear exterior finishes generally demand more frequent inspection and maintenance than pigmented systems.
Plan maintenance from day one
Coated exterior wood should be inspected and cleaned regularly. Renew the finish before widespread breakdown; early maintenance is simpler than stripping and rebuilding a failed system.
