Fypon Cellular PVC - Manual (Page 2)

General Installation Notes
Any adhesives, sealants, fillers or paint used must be compatible with the material that is being installed (see manufacturer’s recommendations in the
Finishing and Adhesives section below). Always use corrosion-resistant mechanical nails or screws along with manufacturer’s recommended adhesive
product when installing all Fypon products. This combination provides a secure, long-lasting bond. Countersink all fasteners about 1 /
8
" and fill with
product compatible filler. Exterior installations should be finished using a manufacturer’s recommended caulk to prevent water infiltration behind
siding, windows and doors. Some exterior installations, in particular new construction before siding is applied, may require a J-channel and/or
flashing to prevent water infiltration. Installers must determine which installation technique is best for the specific situation.
Finishing and Adhesives
Polyurethane (PUR) – Fypon polyurethane products are factory primed. Depending on product location, always use interior/exterior-grade, PUR
compatible adhesives, sealants, and fillers when installing Fypon products. Consult the manufacturer’s recommendations for your particular
climate and the substrate you are installing to.
Cellular PVC – Depending on product location, always use interior/exterior-grade, PVC compatible adhesives, sealants, and fillers when installing
Fypon products. Consult the manufacturer’s recommendations for your particular climate and the substrate you are installing to. If painting is
desired, a 100% acrylic latex paint with a Light Reflectance Value (LRV) of 55% or higher must be used. Applying paint with an LRV of 54% or
lower will void the warranty.
IMPORTANT:
Please read these installation guidelines thoroughly before beginning installation. Please note that these guidelines are provided only to assist with the installation of Fypon moulding
and millwork products. Modified procedures may be required in order to meet specific situations, unique applications and local building codes. The manufacturer does not, under any
circumstances, warrant the installation of its products. Be sure to wear appropriate protective clothing, gloves and safety glasses when working with any tools. Installer should check
for and relocate all electrical wiring within the proposed installation area, as needed (be sure to disconnect all electric power before working with any electrical wiring and follow all
applicable local electrical codes and safety procedures).

Gluing Techniques
• All joints should be glued to prevent joint separation. A Cellular PVC Bonding adhesive should be used for the best results. Read the adhesive
label or consult the manufacturer to confirm that the adhesive is PVC compatible. It may be best to test the application for suitability before
proceeding. It is also recommended that fasteners be used on each side of the joint to allow adequate bonding time.
• Whenever possible, adhesive should be applied to the back side of the trim at the joints. This will help hold the trim at the joints forcing it to
expand and contract in the center preventing unsightly gaps at the joints.
• It is not necessary to glue the full length of the product to the substrate, but adhesive should be used on any application that involves three
or more 18' lengths placed end to end.
• For best results, surfaces to be glued should be smooth, clean and have complete contact with each other.
• Before bonding together two smooth or non-machined surfaces of the PVC, it is recommended that you clean those surfaces with acetone.
• On long lengths of trim, like corner boards or fascia, a scarf joint (opposing 45-degree bevels) should be used.
Expansion & Contraction
• This product expands and contracts with changes in temperature. To minimize this characteristic the recommendations given in the Fastening
and Gluing sections should be followed.
• When installing this product allow 3 /
16
" per 18' for expansion and contraction. Remember that it is recommended that all joints be glued and
where possible, fastened to the substrate to prevent joint separation.
