Maintenance of Metal Post Caps

Copper and stainless steel 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. 

Post Cap FAQ's

Will my stainless steel post caps rust?
Stainless steel is an alloy of iron that contains more then 10% chromium. Stainless steel has a hard oxide coating which makes it resistant to stains. Corrosion and wear strip away this coating causing the steel to rust. To maintain this coating, clean periodically with a mixture of vinegar and club soda.

Installation
How do I attach the post cap to the post?
We recommend using an exterior-grade construction adhesive to adhere the cap to the post.  Apply the adhesive liberally to the inside of the cap and place the cap firmly over the top of the post. If you prefer to use Brad nails, be sure to pre-drill all nail holes to avoid splitting.

What preservative is used to protect pressure-treated wood post caps?
Our wood post caps are protected by CA-B (Copper Azole Type B), an EPA-registered pesticide containing copper and azole compounds to protect it from termite attack and decay. For more information, refer to the Copper Azole Safe Handling Information.

Do I need to apply a finish to my wood post caps?
As with all wood products, we recommend that you coat these 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.
