Treated Pine Decking Installation
Before you install your treated pine decking, you’ll need to make sure you’ve laid the foundation. Have you correctly designed and installed your sub-frame? Have you sealed your deck’s joists and top surfaces with G-Tape? If so, then you’re ready to install your decking.
Treated pine timber will expand when exposed to the elements, so be sure to leave a 5mm gap between decking boards. Fix by using stainless steel screws. Nails are another option but not one we recommend as there is too much movement in the timber.
These should be at least 12mm from the wood decking board edge and fixing holes predrilled at 80% of the screw or nail diameter to avoid splitting.

Treated Pine Decking Maintenance
The hazard rating of your treated pine will guide the parameters of its use and maintenance. Treated pine responds to the environment and weather with time.
It can be expected to crack, split, twist, cup and bow and with continued exposure to moisture and is susceptible to mould.
From the elements and lengthen the life of your treated pine deck, it’s recommended to seal your timber with a primer and coat with either a light colour paint or staining product like Cutek for it to perform at its best.
- Sweep any dirt or leaves from your deck surface.
- Thoroughly wet the deck surface to avoid it drying out for 15 minutes.
- Apply a decking deep-cleaning solution using a bucket and mop.
- Work this into the deck using a stiff bristled brush, allowing it to soak into the deck surface for 15 to 30 minutes.
Marks and discolouration should no longer be visible on your deck. After cleaning, rinse with a garden hose on high pressure (or pressure washer) and allow to dry completely.
