Frequently Asked Questions
Below are some frequently asked questions about caring for our products.
Will my copper post caps remain a shiny copper color?
Our copper post caps come with a thin, clear marine lacquer designed to protect them before and during installation. Once exposed to the elements, the sun’s ultraviolet rays, moisture and pollution begin to break down this coating, exposing the metal underneath. In its natural state, copper breaks down in the elements and patinas. In general, copper progresses from a natural salmon color to a series of russet browns and grays, and finally to a blue-green or gray-green patina.
How do I keep my copper post cap from turning green/patina?
To maintain the shiny look, apply a car wax immediately after purchasing the post cap, and reapply every 3 to 6 months.
Can I speed up the patina process on my copper post caps?
To encourage a natural patina, remove the lacquer with mineral spirits and grade 0000 steel wool.
Will my stainless steel post caps rust?
Stainless steel is an alloy of iron that contains more than 10% chromium. Stainless steel has a hard oxide coating that makes it resistant to stains. Corrosion and wear strip away this coating causing the steel to rust. To maintain this coating, clean the post cap periodically with a mixture of vinegar and club soda.
Will the brass post caps tarnish?
Our brass post caps, like our copper post caps, are a true metal brass—an alloy of copper and zinc. Our brass post caps are protected with a thin, clear coating of lacquer designed to protect them before and during installation. Once exposed to the elements, the sun’s ultraviolet rays, moisture and pollution begin to break down this coating, exposing the metal underneath. Periodic reapplication of this clear coating will help to protect the brass post cap.
Do I need to apply a finish to my wood post caps?
As with all wood products, we recommend that you coat the wood post cap with a high-quality exterior finish to preserve the wood's natural beauty and ensure a lifetime of enjoyment. Apply to all wood areas, including the underside of the cap, before installation.
Should I allow my treated wood post caps to "season" outdoors before I apply a protective finish?
No. Our treated wood post caps are kiln-dried and do not require a drying period. We recommend applying a protective finish immediately to the post cap.
Will the metal solder on my glass post caps oxidize?
Exposure to the elements may cause the copper-wrapped solder on your glass post cap to oxidize and lose its original color. Applying car wax before placing the post cap outdoors will help to prevent the initial oxidation. We have found regular furniture polish to have the same affect, but its prevention time may vary based on geographical location. Reapply the car wax/furniture polish every 3 to 6 months as needed.
