Yes, you absolutely can nail PVC moulding. However, success depends on using the right techniques and materials.
PVC moulding offers a durable and water-resistant alternative to wood. Nailing provides a quick and effective method for installation, but some considerations are important:
Key Considerations for Nailing PVC Moulding
- Nail Type: Brad nails are generally recommended. Their small head minimizes visibility and reduces the risk of splitting the PVC.
- Nail Length: Choose a nail length appropriate for the thickness of the moulding and the substrate it's being attached to. Too short, and the hold will be weak. Too long, and the nail might protrude or bend.
- Nail Gauge: 18-gauge brad nails are a common choice for PVC moulding.
- Nailer Settings: Adjust your nailer's pressure setting to avoid driving the nails too deep and damaging the PVC. Practice on scrap pieces first.
- Proper Spacing: Space nails appropriately based on the size and application of the moulding. Typically, spacing of 12-16 inches is sufficient, but consider more frequent nailing in areas with higher stress.
- Pre-Drilling: For larger or more brittle PVC mouldings, pre-drilling pilot holes can help prevent splitting, especially near edges.
Benefits of Nailing PVC Moulding
- Speed: Nailing is a faster installation method compared to adhesives alone.
- Secure Hold: When done correctly, nailing provides a strong and reliable attachment.
- Ease of Use: Brad nailers are relatively easy to use and readily available.
Potential Problems and Solutions
- Splitting: Pre-drilling and using appropriate nail sizes can prevent splitting.
- Visible Nail Holes: Use color-matched caulk or filler to conceal nail holes for a seamless finish.
- Weak Hold: Ensure the nails are penetrating the substrate adequately and are of sufficient length.
Summary
Nailing PVC moulding is a viable installation method when using the correct nail type, length, and spacing. Pay attention to nailer settings and consider pre-drilling to prevent splitting. With the proper technique, you can achieve a strong and aesthetically pleasing result.
