How to Paint Cellular PVC Trim

Painting cellular PVC trim, Royal Trim & Mouldings

Nothing accents a home quite like trim. It can help create a bold frame for a modern look or offer a decorative touch to tie a more traditional aesthetic together. While white trim is often a popular choice, painting cellular PVC trim can make a statement for the perfect exterior addition.

Cellular PVC trim typically comes manufactured in a white substrate. But while easy, it’s not the hue every homeowner wants nor every home needs, so achieving the preferred look will require you to paint.  Different types of trim react differently to different coatings, and there are also some best practices for painting cellular PVC trim to keep in mind.

PVC vs Cellular PVC Trim

When most people think of PVC, they’re thinking of rigid PVC, which is commonly used in commercial and industrial applications for things like pipes, doors, refrigeration, and tanks. It’s less flexible than other formulations and is commonly known as UPVC, PVC-U, and uPVC (the “U” standing for “unplasticized”).

Cellular PVC, like Royal® Trim and Mouldings and Kleer® from Westlake Royal Building Products™, is an expanded PVC that is ideal for creating shapes. It’s less dense, more flexible, and more moldable than rigid PVC, making it more economical and able to replicate the looks and profiles of wood. It’s also durable, waterproof, low-maintenance, and resistant to dents, scratches, splitting, and warping.

Choosing Paint for Cellular PVC Trim

It’s crucial to select the right coating for cellular PVC trim to ensure it lasts as long as designed. When painting the trim with a color with a light reflective value (LRV) of 57 or above, a high-quality 100% acrylic latex or acrylic blend paint is recommended. For darker colors with an LRV of 56 or lower, it’s crucial to opt for an approved solar reflective coating (such as Sherwin-Williams VinylSafe or Benjamin Moore Colors for Vinyl) to avoid any heat distortion, warping, or buckling over time.

Best Practices for Painting Cellular PVC Trim

When painting cellular PVC trim, there are a few best practices to follow and details to be aware of.

  • Remember that painting cellular PVC trim is different from other materials. Paint adheres to cellular PVC much better than materials like wood. Wood has a 6% moisture allowance, which means it will need to be repainted after three to five years. Cellular PVC trim, however, won’t need to be repainted for upwards of 20 to 25 years if the right paint is chosen and the PVC is prepped properly. Since cellular PVC doesn’t absorb moisture, most coatings will be dry to the touch within an hour or less, but may take 30 days to fully cure (depending on humidity and temperature).
  • Prep the trim. Always clean cellular PVC trim before painting to remove any dust, dirt, or other foreign material. Because some cellular PVC can have a high sheen, lightly scuff the surface to help improve paint adhesion. Priming isn’t necessary; however, the finish quality is greatly enhanced if you use a premium 100% acrylic latex paint for trim with a built-in primer. In addition, a primer may be required under the paint manufacturer’s warranty. If you do use a primer, make sure to follow the same LRV limitations, as some primers can be dark and can create heat distortion issues.
  • Paint after the trim is installed. While trim can be painted prior to installation, doing so will necessitate touch-ups around fasteners. Painting after installation can help avoid repetitive touch-ups, and if the homeowner isn’t sure about color choice, installers can move forward with the job before the decision is made.
  • Follow paint manufacturer’s instructions. Again, it’s important to select a solar reflective coating when using a 56 LVR or lower paint. Installers should also carefully read and follow the paint manufacturer’s instructions as they can offer additional insight on coloring and coating requirements.

5 Best Practices for Going Bold With Exterior Color

Kleer trim

When used well, bold colors can add a tasteful pop of life to a home’s exterior. When used poorly, you can end up attracting negative attention.

Here are five tips from Trisha Wagner, senior product manager and an authority on color at Boral Building Products, to ensure your use of bold is gorgeous, not gaudy.

1. The best place for bold color is in a home’s decorative details
While it always depends on the house, bold colors are generally best used in a home’s accents, such as the shutters and front door. It’s one of the fastest ways to have a large impact and can completely transform a home’s look and feel. Even better, these details are often the easiest—and most affordable—to change later with either a fresh coat of paint or replacement.

2. Remember to coordinate
One of the first things to consider when picking bold accents is the home’s siding color. You want to select accent colors, such as on the trim, shutters, and front door, that work well with the siding, so consult the color wheel for reference. As explained on Color Matters, “color harmony” can be achieved by choosing analogous colors (three colors side by side on the wheel) or complementary colors (directly opposite each other on the wheel). This can be especially helpful in moving beyond traditional colors. For example, instead of the typical pale yellow, try a deep maize yellow paired with red, coral, or cobalt accents.

3. Pay attention to the entire home exterior
The front of the home isn’t the only area people see. Don’t forget to decorate the back and sides of a house, particularly since outdoor living is more important to buyers than ever before. A bare side or rear home exterior looks and feels unfinished; shutters and accents on these walls will add dimension and complete the look.

4. Find what works for you
If clients are uncertain about incorporating bolder colors, encourage them to experiment with different tones before making their final selection. If a home’s style doesn’t support shutters, consider using just a bold trim color. You can also soften a home’s look by pairing white or cream trim with one or two bold accents. For a less-permanent option,  incorporate bold colors into the landscape design, such as bright-red or -purple flowers and plants, a jewel-toned bird bath, or even a painted fence.

5. Don’t discount the power of white
In the sea of tans and beiges that dominate today’s exteriors, white becomes a stark contrast that is a bold choice in and of itself. A crisp white trim against a richer-toned cladding is eye-catching and stands out from homes with cream accents.

4 Best Practices for Beautiful Siding Installation

Professionals know it’s not only the quality of the product that determines how polished a home’s siding looks, but also how well it is installed.

While having on-site experience can develop the skills for top-notch installation, sometimes even the most experienced builders make mistakes. Here are four tips to ensure your Grayne and Foundry siding projects are beautiful every time.

1. Use the Right Tools
Before you begin the installation process, it’s essential to be equipped with the right tools. Accidentally using the wrong tools can have consequences.

To cut the siding, use either a vinyl siding blade or a fine-toothed blade. If using a fine-toothed blade, be sure to install the blade in reverse for the best cuts.

Other tools to include on your checklist:
• Utility knife
• Caulking gun (to seal J-channel)
• Vinyl siding snips (to cut or trim siding panels)
• Siding removal tool
• Snap lock punch (to cut snap lock tabs and allow cut panels to be snapped into utility trim)
• Nail hole slot punch (to add nail holes if a panel must be face nailed)
• Trim nail punch (to add nailing holes if a panel must be face nailed)

2. Start with a Smooth Surface
If the surface beneath the siding is uneven, even the best siding installation may be compromised. Take appropriate precautions to ensure a smooth, continuous surface.

For new construction, avoid using green lumber as the underlayment, as it typically has high levels of moisture. As the wood dries, it will shrink, leading to cracking and warping. These flaws in the wood can make the siding look uneven and poorly installed.

If you are re-siding a building, furring or complete removal of uneven original siding may be required to create a smooth surface. While this process may seem like a nuisance, it will help to ensure straight, stable replacement siding.

3. Plan for Expansion and Contraction
To accommodate expansion, see siding manufacturers’ guidelines, as many panels install differently.

Always leave a minimum of 1/8″ gap at the nailing hem to accommodate changes from temperature shifts. If you’re installing siding in temperatures of 75 degrees F or higher, lessen the clearance slightly to at least a 1/16″.

4. Apply Panels Correctly
One of the most common mistakes installers make when applying panels is driving the head of the fastener tightly against the nail hem. Allow approximately 1/32″ (roughly the thickness of a dime) clearance between the fastener head and the siding nail hem.

During installation, avoid face-nailing or stapling through siding. Face-nailing can not only cause ripples in the siding, but also prevents proper expansion and contraction.

When installing a siding panel, push up from the bottom until the lock engages, then let the panel relax down against the ledge of the previously installed panel. Without stretching the panel, reach up and fasten it into place. Again, be wary of tightness—the panels should not be under tension or compression when they are fastened. Once fastened, allow the butt edge to rest on the top edge of the course below.
