Questions about PVC Board

Use 8d stainless steel annular shank nails, or screws that are designed for wood trim, and are long enough to penetrate the solid substrate a minimum of 1 1/2 in. Simpson Strong-Tie makes an 8d nail with a 7d head in a 12-gauge thickness, available loose or collated, allowing it to be gun-nailed. The nail is called the Trifecta. It is half annular (tip) and half ring-shanked, and made from 316 stainless. Screws are better for limiting the thermal movement of the trim. Allow PVC trim to acclimate to outside temperatures before installing. Bond PVC trim joints to prevent separation. Be sure to allow adequate expansion and contraction space at the end of long runs. If possible, decrease the on-center spacing between fasteners to 12 in. or less, and bond boards to substrate when practical. Where you have an expansion joint, leave a full 3/16-in. gap when installing on a day where temperatures range from 30F to 40F. Leave a gap just large enough to accept a bead of sealant, or no gap at all (adhesive bond), when installing on a day when temperatures range from 80F to 100F. Shiplap joints are superior to scarf cut joints, especially on long runs. If practical, install long runs of trim when the outside temperature and the temperature of the PVC trim board is 55F to 65F, in order to minimize thermal movement in the trim.

Trowel the masonry with a sealant or adhesive to provide a level surface to accept the PVC trimboard. Then secure the trim to the masonry with Tapcon masonry fasteners.

4.How do I seal the open cells if I cut the PVC trimboard? Also, how do I clean PVC trimboards?

Handle PVC trim as you would a piece of premium lumber. Be careful not to damage the visible surface of the board. To seal cut edges or clean a cut edge that has gotten dirty, sand them with 320 grit sand paper, and then wipe the edges with Acetone”this will help to re-seal the cells. To remove dirt and grime from the visible surface or edges of PVC trimboard, use Soft Scrub with Bleach, one of a variety of Clorox products (Clorox Outdoors, etc.), Mr. Clean Magic Erasers? with a little water, or Corte Clean, a composite deck cleaner that has been found to clean cellular PVC trim. As with any new product, try the cleaner in an inconspicuous area before cleaning the trimboards on your project.

5.What are the recommended sealants I should use with PVC trim?

As with adhesives, look for products that contain some type of solvent. NPC Solar Seal Sealant/Adhesive in Trimboard white has been found to be one of the best sealants for sealing and bonding PVC trim to itself, as well as many other substrates. Other recommended sealants include Quad and EP-1000 Enhanced Polyurethane by OSI, and Geocel 2300, or other polyurethane sealants. Do not use silicone sealants, as they are not compatible with cellular PVC trim.
