How To Fill Nail Holes In Pvc Molding

i. Does PVC trim require a primer?

A primer is simply needed if yous want the pigment manufacturer's warranty. Excellent adhesion can be achieved by properly cleaning the board before applying a topcoat of paint to PVC trim. (Refer to painting guidelines in the Versatex contractor handbook for more information on painting PVC trim.)

A Notation from the Publisher:

WARNING: POTENTIAL Conflict OF Involvement!!

If you lot are sensitive about articles that seem to favor a item manufacturer, then DON'T read this one!! It's written by the President of Versatex! Just after years of experience, I've institute that some manufacturers know more than virtually their products than anyone else; if a carpenter wants to learn the all-time way to install a product, sometimes the best source of information is the manufacturer. In the future, wait for more carefully-screened manufactures from manufacturers.

2. What blazon of paint practice you recommend for coating PVC trim?

Just most whatever 100% acrylic latex, or 100% acrylic latex with a urethane condiment, can be used to achieve superior coating durability and flexibility. Lacquers are non recommended with PVC trim because lacquers are a more than brittle coating, and volition not flex with any motion in the PVC trim. Paints like Duration by Sherwin Williams, Manor Hall paints by PPG and Moorelife past Benjamin Moore adhere well to PVC trim.

Paint on PVC trim volition final three to v times longer than paints on wood or woods composites due to the absenteeism of moisture in the substrate. Sherwin Williams likewise offers a field-applied coating under their "Light-green Seal®" product designation. Kem Aqua® BP Enamel is a water-reduceable polyurethane, acrylic topcoat that offers fast dry times and no critical re-glaze times. Due to its excellent adhesion properties, it is an ideal blanket for Cellular PVC.

3. Can PVC trim be painted nighttime colors?

But light-to-medium colored paints—with a lite cogitating value of 55 units or greater—should be practical to PVC trim. For instance, using paint with an LRV below 55 units will void our product warranty. LRV is measured based on colour and its ability to absorb heat. Thus, an LRV of nix (0) is black, and an LRV of one hundred (100) is white. Don't assume the paint is a light color. Nosotros have had cases where contractors believed that the pigment they used was a light beige, only to discover out it had an LRV in the 20s or 30s. Consult the paint manufacturer for the LRV of your paint before applying information technology to cellular PVC trim.

4. How long does information technology take the paint to cure on PVC trim?

That depends on the weather weather condition. Warm/dry atmospheric condition, or warm/humid atmospheric condition, will allow the paint to cure faster than cool weather. Information technology can take upward to 30 days for paint to fully cure on PVC trim, because PVC trim is impervious to moisture. For the paint to cure, the moisture must evaporate through the surface of the blanket that has skimmed over from drying.

v. What is the all-time glue for joining two pieces of PVC trim? What is the best glue for bonding PVC trim to wood? How about metal?

We recommend PVC pipe glue with solvent for bonding the ends of PVC trim boards to themselves (Weld-On 705 by IPS, TrimTight by Trim Mucilage, Inc. or Christy'due south Red Hot). Be certain the PVC pipe glue has sufficient working time to permit you to apply the glue and push the boards together before information technology cures.

If you are looking for more of a structural bond at shiplap or scarf joints, miter cuts (window surroundings), or for gluing sheets of PVC trim, we recommend PVC TrimWelder. For bonding to woods, we recommend Liquid Nails Sub-Floor Adhesive or Heavy Duty Construction Adhesive. For PVC trim to metal, PVC TrimWelder Adhesive works best.

There are three types of PVC TrimWelder Adhesives. Slow and Fast Cure for field joints and small glue-ups, and Laminating Grade for canvas glue-ups. Slow Cure should non be used at temperatures beneath 40°F. Remember to apply any adhesive to but ane bonding surface, thus allowing the adhesive to penetrate into the cells on the other trim slice.

half-dozen. What is the best fastening arrangement for PVC trim that also hides the fastener caput?

The best overall arrangement for securing PVC trim is the Cortex Curtained Fastening System. It combines the advantages of using screws (strong connexion) with the PVC trim tapered plug that fits into the hole created by the screw, thus eliminating the need for fillers or sealants to fill the nail holes. When comparison the price of this fastening system to nails, keep in heed that you won't have to go dorsum over the trim filling in the nail holes.

7. What are your recommendations for dealing with expansion and contraction?

Use 8d stainless steel annular shank nails, or screws that are designed for wood trim, and are long plenty to penetrate the solid substrate a minimum of 1 one/2 in. Simpson Strong-Tie makes an 8d nail with a 7d caput in a 12-gauge thickness, available loose or collated, assuasive 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 move of the trim. Allow PVC trim to acclimate to outside temperatures before installing. Bond PVC trim joints to foreclose separation. Exist sure to allow acceptable 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 total iii/xvi-in. gap when installing on a twenty-four hours where temperatures range from 30°F to twoscore°F. Leave a gap merely large plenty to accept a bead of sealant, or no gap at all (adhesive bail), when installing on a day when temperatures range from 80°F to 100°F. Shiplap joints are superior to scarf cutting joints, specially on long runs.

If applied, install long runs of trim when the outside temperature and the temperature of the PVC trim lath is 55°F to 65°F, in lodge to minimize thermal motion in the trim.

8. What is the all-time way to secure PVC trim to masonry?

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

9. How practise I seal the open up cells if I cut the PVC trimboard? Likewise, how do I clean PVC trimboards?

Handle PVC trim as you would a piece of premium lumber. Be conscientious not to damage the visible surface of the board. To seal cut edges or make clean a cut border that has gotten dirty, sand them with 320 dust 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, i of a multifariousness of Clorox products (Clorox Outdoors, etc.), Mr. Clean Magic Erasers® with a piddling water, or Corte Clean, a composite deck cleaner that has been found to clean cellular PVC trim. As with whatever new product, try the cleaner in an camouflaged surface area before cleaning the trimboards on your project.

10. What are the recommended sealants I should apply with PVC trim?

Equally with adhesives, look for products that contain some type of solvent. NPC Solar Seal #900 Sealant/Adhesive in Trimboard white #111 has been found to be one of the best sealants for sealing and bonding PVC trim to itself, also as many other substrates. Other recommended sealants include Quad and EP-g Enhanced Polyurethane by OSI, and Geocel 2300, or other polyurethane sealants. Do not apply silicone sealants, as they are not compatible with cellular PVC trim.
