2.02 ACCESSORY PRODUCTS
A. FASTENERS:
- Use stainless steel fasteners designed for wood trim and siding for best results. Fastener should have sufficient flexural and tensile strength to resist bending.
- Fasteners with thin shanks, blunt points, and full round heads are preferred. The fastener must be long enough to penetrate the substrate a minimum of 1 1/2”.
- Do not use staples, small brads and wire nails. Avoid using finethreaded 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 material.
- Pre-drilling typically is not required unless large fasteners are used or the product is installed during low temperatures.
- Use two fasteners for every framing member for trimboard applications. VERSATEX Sheet and trimboards 8 inches and wider require additional fasteners.
- Install fasteners no more than 2 inches from the end of each board.
- Avoid fastening VERSATEX over hollow or uneven areas. Fasten Versatex onto flat, solid substrates.
- 3/8” and 1/2” thick VERSATEX Sheet and Beadboard are not designed to be ripped and used for trim applications. These products must be glued and mechanically fastened to the substrate.
- B. ADHESIVES:
- All bonded surfaces must be smooth, clean, and in complete contact with each other for best results.
- For adhering VERSATEX to itself, bond joints with PVC cement or cellular PVC adhesives to prevent joint separation. Products such as Bond-and- Fill (2 component epoxy), IPS Weld-On 705 (white), and Genova Vinyl Adhesive are excellent cements
- Remember that most PVC cements cure quickly (3-5 minutes), and have a limited working time.
- Scarf cut joints are recommended.
- Bonded joints should be secured with fasteners and fastened on each side of the joint.
- When bonding VERSATEX to other substrates, consult the adhesive manufacturer to determine suitability.
- If you have to butt joints, double nail the trimboards on both sides of the butt joint and reinforce with construction adhesive applied to the backside of the trimboards.
- C. SEALANTS:
- Use urethane, polyurethane, polymer blends or acrylic based sealants that do not contain silicone.
2.03 FINISHES
- VERSATEX does not require painting for protection. If painting is preferred, follow these guidelines.
- A. PREPARATION:
- Be sure the VERSATEX surface to be painted is clean, dry, and free of dirt, loose or peeling paint, mildew, chalk, grease and any other surface contaminants before paint application.
- Use 100% acrylic latex or 100% acrylic latex with urethane additive paint with a light reflective value equal to or greater than 55 units.
- Follow the paint manufacturer’s application recommendations.
- Nail holes may be finished with a two component methacrylate, poly urethane, polymer, or acrylic based caulk, or painted over. Use a caulk that is UV resistant.
PART III EXECUTION
3.01 INSTALLATION
Manufacturer’s instructions: Comply with manufacturer’s installation instruction and product technical bulletins.
- A. CUTTING:
- VERSATEX can be cut using standard woodworking saws. Conventional carbide-tipped blades designed for cutting wood are preferred. Avoid using fine-tooth metal-cutting blades.
- Rough-cut edges are typically caused by excessive friction, poor board support, or worn or improper tooling.
- B. DRILLING:
- VERSATEX can be drilled using standard woodworking drill bits. Do not use drill bits made for rigid PVC.
- Avoid frictional heat build-up.
- Remove shavings periodically from a drill hole as necessary.
- C. ROUTING:
- VERSATEX can be routed using standard woodworking router bits. Carbide-tipped router bits are preferred.
- Routing VERSATEX provides a crisp, clean edge due to VERSATEX’s consistent density.
- D. MILLIING & MOULDING:
- VERSATEX can be milled or moulded using standard milling or moulding machines found in millwork shops.
- Rake angle 20 to 30 degrees. 25 degrees appears to work the best.
- Cutting speed to be optimized with the number of knives and feed rate.
3.01 INSTALLATION
- E. ROUTING:
- VERSATEX can be routed with virtually any piece of equipment used to rout wood.
- Carbide tipped router bits are recommended.
- Machinery that allows for multiple cutting speeds will allow you to optimize the process obtaining a smoother finished part.
- F. EDGE FINISHING:
- Traditional sanding, grinding or filing tools used for woodworking are preferred.
- G. NAIL LOCATION:
- For trimboard applications, use 2 fasteners per framing member.
- Additional fasteners are required for trimboard 8” and wider.
- For trimboard applications, use 2 fasteners per framing member.
- Fasteners must be installed a maximum of 2” from the end of each board.
- H. EXPANSION AND CONTRACTION:
- VERSATEX expands and contracts with changes in temperature. Properly fastening VERSATEX along its entire length will minimize expansion and contraction.
- Allow 3/16-inch space per 18-foot run of VERSATEX for expansion and contraction.
- Bond joints between pieces of VERSATEX to eliminate separation.
- Allow expansion and contraction space at the ends of long runs.
- I. CLEANING:
- VERSATEX can be cleaned with mild detergent and water. Products with pumice, such as Soft Scrub® with Bleach, may be applied with an abrasive nylon brush. For more stubborn stains use a mild household cleaner and degreaser like Clorox Cleanup or Clorox Outdoors.
