Post Cap FAQ's
What is the metal underneath the post caps with the powder-coated finish?
The base of our powder-coated post caps is made of stainless steel.
What is powder-coating?
Our white, green, real patina, pewter and black post caps are all treated with powder-coating. Powder-coating is a dry finishing process in which finely ground particles of pigment and resin are electrostatically charged and sprayed onto an electrically grounded post cap. The charged powder particles adhere to the grounded post cap until they melt and fuse into a smooth coating in the curing oven. The result is a uniform, durable, high-quality finish that is also environmentally friendly.
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.
