FAQs
Will this fit a standard 100mm fence post?
No, this finial is specifically designed for 90mm square posts and will not fit larger dimensions.
Do I need to glue the finial down?
While gravity may keep it in place, it is recommended to use exterior wood adhesive or small finishing nails to ensure it stays secure during high winds.
Can I paint this finial?
Yes, you can paint or stain the finial to match your specific decking or fence color, provided you use exterior-rated products.
Is this finial weather-proof?
It is designed for outdoor use; however, like all exterior wood products, it benefits from regular maintenance and treatment.
Does the finial come with screws?
No, the product does not typically include fixings, so you should purchase exterior-grade nails or screws separately.
Troubleshooting
The finial is loose on the post
Check that the post is exactly 90mm. If the wood has shrunk due to drying, use a small amount of exterior wood filler or shims to create a tighter bond.
The finish is fading or showing signs of water wear
Lightly sand the surface and apply an exterior-grade timber preservative or brown wood stain to restore the finish.
Pros and Cons
Pros
- Provides a clean, finished appearance to outdoor structures
- Helps protect the vulnerable top surface of timber posts from water damage
- Easy to install on standard 90mm square timber
- Durable build suitable for long-term outdoor exposure
Cons
- Compatible only with 90mm square posts
- Finish may require periodic maintenance or re-staining over time
- Not suitable for round or non-standard sized posts
Setup, Compatibility & Care
To install, ensure your timber post is trimmed flush and is exactly 90mm wide. If the post top is rough, lightly sand it to ensure the finial sits flat. You may use exterior-grade wood glue or appropriate wood screws for a secure hold, depending on your preference for aesthetics versus permanency. For maintenance, check the finials annually when inspecting your deck or fence. Apply a fresh coat of outdoor timber stain or wood preservative whenever you treat the rest of your structure to ensure the finish remains uniform and protected against UV degradation.
