Fastening VERSATEX Trimboard

Use 12 gage stainless steel fasteners designed for wood trim and siding. Fasteners with thin shanks, blunt points, and full round heads are preferred; annular threaded or spiral type nails are also recommended. The fastener must be long enough to penetrate the substrate a minimum of 1 ½ inches.
If screws are preferred use a #7 stainless steel finishing B/B screw with a painted white head.
Some galvanized fasteners will rust astaining VERSATEX which is why stainless fasteners are preferred.
Be sure the fastener has sufficient flexural and tensile strength to resist bending.
Do not use staples, small brads and wire nails. Avoid using fine-threaded wood screws and ring-shank fasteners.
Use standard nail guns with a pressure setting between 70 psi and 100 psi. The recommended pressure depends on the type of gun, type of nail, ambient temperature, and the substrate. Care should be taken not to overdrive the nail into the trim.
Pre-drilling typically is not required unless large fasteners are used or the product is installed during low temperatures, typically below 40°F. See Technical Bulletin C-2.
On 4 inch and 6 inch trimboard applications, use a minimum of two fasteners for every framing member. VERSATEX Sheet and trimboards 8 inches and wider require additional fasteners. See Technical Bulletin C-2.
Install fasteners no more than 2 inches from the end of each board. See Figure B.
Do not fasten VERSATEX over hollow or uneven areas. Fasten VERSATEX onto flat, solid substrates.
VERSATEX Sheet and Beadboard ½” or thinner are not designed to be ripped and used for trim applications. These products must be glued and mechanically fastened to the substrate.
