Description
Siparila Topcoat® trim boards ensure the long-term durability of our wood siding, with several solutions available for finishing the exterior and interior corners of the home. Regardless of the solution you choose, we recommend that your corner trims are fastened using round head, hot-dipped galvanized nails that have a minimum length of 2½ inches. Also, the nail head must not dig into the wood, but sit flush on the surface to protect against water damage.
