Smart Buy Agate Grey 10mm Capping Board (5m) – FAQs
What sizes are Smart Buy Agate Grey capping boards available in?
This Agate Grey 10mm range is available in 175mm, 225mm, 300mm and 400mm widths, all supplied in 5m lengths. If you’re covering existing timber fascia, measure the visible face and choose the nearest width that gives full coverage.
Do Smart Buy Agate Grey capping boards come with a guarantee?
Solid yes. The foiled Agate Grey finish is backed by a 10-year manufacturer’s guarantee.
Are matching accessories available in Agate Grey?
Yes — joints, corners and trims are all available in matching Agate Grey, so you don’t end up with a patchwork finish.
What fixings should I use for Agate Grey capping boards?
Use colour-matched polytop pins or nails. Fix into the timber behind, don’t overdrive them, and keep spacing consistent so the board sits flat without rippling.
Can I fix gutter brackets through a 10mm capping board?
You can — but only if the timber behind is sound. The fixing needs to go through the board and into solid timber.
If the fascia is soft or failing, you’re better off going with full replacement fascia.
