Use corrosion-resistant, smooth shank, screw, annular threaded or spiral type nails, at least 6d in size and long enough to penetrate at least 1 1/2” into the substrate. Stainless steel fasteners are preferred over galvanized steel.
If using a nail gun, adjust the length of the stroke, not the air pressure to control nail depth.
If the temperature of the moulding is below 40°F, pre-drilling is recommended to avoid cracking.
If screws are preferred, use drywall or deck screws with a large thread or flute, long enough to penetrate substrate by at least 1”.
Slightly countersink screws and finish holes using an exterior spackling or sealant.
Nails should be placed 12” on center and 3/4” from each edge.
All bonded surfaces must be smooth, clean, and in complete contact with each other.
Use exterior-grade, PVC compatible, urethane-based adhesives for bonding VERSATEX mouldings to various substrates. Use solvent-based PVC cement to bond the mouldings to each other.
Recommended sealants/adhesives include Solar Seal 900 from NPC and Liquid Nails Sub Floor and Heavy Duty Construction Adhesives.
Use adhesive sealants in addition to mechanical fastening to secure the mouldings to the building frame whenever possible.
Detail - Brick Moulding Installation Guidelines
Measure top brick mould to overlap the Jamb material by 1/2”. This will allow for a 1/8” to 1/4” reveal around the jamb. Cut a 45° angle on the brick mould ends, butt or angle joint middle seam if needed. Note: Reveal may vary depending on siding, siding J-channel, brick or block installation. Be sure the moulding pieces are fairly tight and with minimum gaps. Properly seal the moulding pieces to the brick.
When nailing, use 8d nails or 3” galvanized finishing nails. Space nails 8” to 10” apart. Counter sink nails 1/16” below the surface of the brick mould. Nails should penetrate the structural frame at least 1”. To conceal nail holes, use a sealant or epoxy. Sealants such as Quad by OSI or NPC Solar Seal 900 sealants work well with cellular PVC products. If you prefer a harder, more durable surface, PVC TrimWelder is recommended.
Nails can be placed as close as 3/8” to the edge of the brick mould. For optimum fit, use Weld-On 705 white PVC adhesive or equal to bond the mitered corners of the brick mould. If you prefer to bond the brick mould to a wood substrate, we recommend Liquid Nails Sub Floor or Heavy Duty Construction adhesives.
Seal around the brick mould where it meets the siding material. When installing a storm door or combination door be sure the brick mould is firmly attached before installing the combination door.
