Learn How to Glue PVC Boards Trim & Molding the Easy Way

I love using PVC boards and trim for finishing work. Not only is the material easy to work with, but it also lasts way longer than wood trim because it’s waterproof and far more durable.

I constantly pin them in place with brad nails for extra security, but gluing them is just fine. I’ll teach you how to do it right here.

What are PVC Boards?

PVC (polyvinyl chloride) boards, trim, and molding are popular building materials that are lightweight, durable, and easy to install.

They’re often used for window and door trim, baseboards, tile trim work, and other decorative elements in a home. You can cut, glue, and even paint them; they last much longer than their wooden counterparts.

I prefer the extra security of brad nailing them in place, but that’s just me. You don’t have to, and PVC adhesive is just fine.

How to Glue PVC Boards and Materials

Learn How to Glue PVC Boards Trim & Molding the Easy Way 1
  1. Get your tools and materials: You’ll need whatever PVC boards, trim, or molding you’re using, plus PVC adhesive, a putty knife or caulking tool, a clean cloth or paper towels, and a saw (if you need to cut the PVC to size).
  2. Prepare the surface area: Clean the area where the PVC materials will be glued. Wipe everything, so it’s free of dust, debris, and other contaminants. This will help it stick perfectly.
  3. Measure and cut the PVC: Measure the area where you’re applying the PVC and cut the materials to size. If you’re using PVC trim or molding, you’ll need to make sure the cuts are precise to ensure a tight fit.
  4. Apply the adhesive: Use the putty knife or caulking tool like a caulking gun to apply a thin, even layer of PVC adhesive to the back of the PVC boards, trim, or molding. Make sure to cover the entire surface. Then do the same for the spot you’re sticking it to.
  5. Press the PVC into place: Wait for both glued surfaces to become tacky (about ten seconds), and then stick the trim in place. This will give you a better adhesion. Carefully press the PVC boards or trim, ensuring it’s level and flush with the surrounding surface.
  6. Wipe away excess adhesive: Use a clean cloth or damp paper towel to wipe away any excess adhesive that may have squeezed out. Avoid a dry paper towel as it can stick to the glue.
  7. Let the adhesive dry: Allow at least 24 hours for everything to dry before using the area.

Best Adhesive for PVC Materials

PVC adhesive comes in different formulations; some are specifically designed for different types of PVC, so make sure to use a suitable adhesive for the various PVC materials you’re working with. For standard boards and trims, use something like Titebond glue for plastics.

Tips for Working with PVC Boards and Trim

  • Work in a well-ventilated area with fans or open windows and wear gloves.
  • Apply the adhesive evenly to ensure a secure bond and avoid any PVC warping.
  • Wipe excess before it dries.
  • Avoid getting it on your skin.

With patience and the right tools, you can easily glue PVC boards, trim, and mold to any surface.

PVC Boards vs MDF Boards for Home Interiors

PVC (polyvinyl chloride) boards and MDF (medium-density fiberboard) are popular building materials commonly used for home interiors.

Pros of PVC Boards

  • Waterproof: PVC boards are waterproof and are not affected by moisture, which makes them excellent for wet bathrooms, humid kitchens, and other areas where water is present.
  • Durable: PVC boards are durable and can withstand heavy use and impact.
  • Easy to clean: PVC boards are easy to clean and maintain, which makes them ideal for high-traffic areas.
  • Affordable: PVC boards are relatively affordable compared to other building materials.

Cons to PVC Boards

  • Limited colors and finishes: These boards and trims are typically only available in a limited range of colors and finishes, with white being the most common.
  • Not environmentally friendly: PVC boards are not environmentally friendly and can release harmful chemicals when burned. So, wear a mask when using a power tool to cut the material.
  • Can’t paint them: PVC boards can’t be painted, so it’s hard to change the color once installed.

Pros of MDF Boards

  • Affordable: MDF is a cost-effective option for home interiors. You can even buy it in sheets and rip down your custom materials.
  • Very versatile: They can be primed, painted, stained, or laminated to match any decor, and they can be cut, drilled, and shaped to fit any project.
  • Stable: MDF boards are nice and stable and won’t warp or swell like natural wood.
  • Smooth surface: They’ve got a nice smooth surface that doesn’t need to be sanded, which makes them perfect for painting and finishing. You can even stain it.

Cons to MDF Boards

  • Not waterproof: MDF boards aren’t waterproof and do absorb moisture, which can cause them to swell, and you can’t sand it down as you could with wood.
  • Not as durable as PVC: MDF boards don’t have the durability of some other building materials and can be damaged by heavy use or a quick impact.
  • Releases harmful chemicals: MDF boards can release harmful chemicals like formaldehyde when cut, drilled, or sanded. So wear protective gear like masks and respirators.

Upfront, no. But in the long run, yes. This is because they last longer and don’t require extra finishing or installation hardware.

In the End

PVC boards are ideal for areas of the home that are exposed to moisture, while MDF boards are a versatile and affordable option for interior projects.

Both materials have benefits and drawbacks, and the right choice will depend on the specific application, budget, and personal preferences.
