Though redwood will perform better than most other woods if left without a finish, it will look better and last longer if a protective finish is applied and maintained.
Clear water repellent finishes containing mildewcides help preserve the natural appearance of redwood siding. They may not, however, prevent the natural color changes associated with the weathering process. Clear water repellents or water repellent preservatives are the most natural types of finishes, but they are also the least durable. They require reapplication every one to two years. These finishes can be used on decks, fences, siding or other exterior projects.
Transparent and semitransparent stains may last from three to four years. These finishes contain pigments which protect the wood from the degrading effects of solar radiation. The best products contain water repellents, mildewcides and ultraviolet light blockers or absorbers. When selecting a pigmented stain, CRA recommends testing finishes on a small area to be sure the desired color effect is achieved. Transparent stains contain less pigment than semitransparent stains and provide a more natural look. These finishes can be used on decks, fences, siding or other exterior projects.
A wide variety of finishes can be used on interior redwood, including the option of using no coating at all. Areas, such as kitchens and baths, which are subject to moisture need the most protective finishes. Alkyd resin or polyurethane sealers and varnishes are appropriate for these areas. Elsewhere, wax finishes, penetrating oils, stains and paints may be used.
Redwood takes and holds paint better than most woods. It is important, however, to select and correctly apply the right primer. Use oil- or alkyd-based primers or water-born stain-blocking primers on redwood. These primers are available from many paint manufacturers and are formulated especially for redwood, cedar and other wood with a high extractive content. Follow the manufacturer’s recommendations for application closely. The best finishes will not perform if they are applied incorrectly. High quality acrylic latex top coats provide the best durability.

The 45-degree roof slope transmits low-angle sun in the winter and reflects high-angle sun in summer. This increases heat in the winter and reduces it in the summer. It also provides ample headroom and plant-hanging space. The steep roof slope sheds snow in the winter and can withstand a snow load of 18 lbs. per square foot.
A convenient Dutch Door Entry provides additional ventilation control and access.
The frame base of the GardenHouse is a durable plastic with the authentic look, color, and texture of redwood, but with the consistent properties of plastic, making it resistant to insect and moisture damage. A foundation is not required. It is only necessary to prepare a flat surface of gravel, wood, cement, or other material as indicated.
Automatic Vents Simplify Climate Control
Automatic vent operators on the roof and base vents require no electricity or batteries.
The vent operator contains a paraffin (wax) that expands when the temperature reaches about 65°F, pushing the vent open to its fully opened position at about 85°F.
As it cools and the paraffin contracts, the operator’s springs draw each vent closed.
It is adjustable within approximately 5°F and easily detachable for manual operation.
