Like all treated pine products, all cuts should have an end seal coating applied.
The best product we know of is called “Ecoseal.” It is a green coloured, copper based re-sealing solution. Ecoseal is intended to be a supplemental product to use on treated timber that is compliant with AS1604.
Natural oils such as linseed oil can be used as a protective treatment for sleepers. These oils penetrate deep into the wood, offering protection against moisture and decay.
Your treated pine decking must be sealed before or immediately after the timber is installed. It is advisable to use a quality primer and paint in light colours.
Seal the Ends
The ends of railway sleepers are particularly prone to rot, as they soak up water easily. Applying a good quality wood preservative or sealant to the ends can slow down the absorption of moisture and help prevent rot from setting in.
Pine Sleepers can be used for ponds because they are moisture-resistant and not susceptible to decay or rotting. Provided the pond is appropriately tanked and sealed from within, treated timber sleepers create a visually appealing water feature that will blend in with the surrounding elements of the garden.
Unfortunately a perception has developed that treated timber does not need painting. While the preservative treatment will protect against decay and insect attack for decades, the timber is still prone to the effects of general weathering such as splitting, warping, fading and surface discoloration.
Untreated, pine is prone to splintering, rotting, and termites.

Although treated pine is treated with preservatives before the sale, this does not make the timber impervious to harmful environmental conditions over time. Oiling the timber will help to protect it from atmospheric and environmental exposures that can damage the wood.
A: When used correctly treated pine sleepers may last up to 20 years. Q: What Does Wet Treated Pine Sleepers Mean? A: Wet treated pine sleepers are non-structural, cost effective product ideal for, garden edging, fencing, base boards and other outdoor requirements.
Yes. While treated wood is protected against insects, rot, and fungi, it is not protected against moisture, mold, mildew, or UV rays. Sealing your pressure-treated wood annually can help prevent your wood from swelling, cracking, cupping, and warping, as well as preventing discoloration.
A penetrating oil like CUTEK® protects wood from the inside out. It works by penetrating deeply into the timber to repel moisture. It also helps to stabilise wood, preventing cupping, splitting and warping.
When using a screw to fasten treated pine, it is recommended the fixing embeds at least 60% of the secondary material (50mm Timber – 30mm embedment minimum). Please note that fasteners will vary depending on the size of your timber and the required strength of your fixing.
Intergrain Ultradeck has been designed to be used on treated pine, with long-lasting, semi-transparent wood stain, this water based product delivers outstanding durability. It weathers naturally and is ideal for changing the colour of treated pine and reviving faded timber.
A washcoat of shellac comes first. This serves as a sealer; it's essential to close the pores of the pine and provide a foundation for the stain. Shellac dries very quickly and gives the wood absolute clarity.
Yes. Although pressure-treated lumber is pre-treated with chemicals, preventing insect damage, it is NOT waterproofed.
If you want a more natural look and don't mind reapplying the product every few years, then fence stain is the way to go. On the other hand, if you want a long-lasting finish with better UV protection, then fence paint is a better option.
Yes, you can leave pine wood unfinished, but it’s not recommended if the wood will be exposed to moisture or heavy wear. Unfinished pine is susceptible to staining, warping, and damage over time. Applying a clear finish, oil, or varnish will help protect the wood while maintaining its natural appearance.
Always apply a clear sealer coat that is compatible with the stain. A clear sealer is a product that protects knots from bleed-through and seals the grain to produce an even stain color. This adds all the protection you need.
I prefer the unstained look of pine. Don't stain it. Just put a clear wipe-on polyurethane on it. The poly will give it a slight honey cast, and age will turn it golden.
(Chromated Copper Arsenate) – CCA Timber Treatment
Created as a fungicide and termiticide, CCA is the most popular timber treatment type used today. Applied to wood using a pressure treatment, CCA is extremely effective, cost efficient, and more widely available than its counterpart—ACQ.
Pressure treated lumber needs time to dry out completely before it's painted. Showing a little patience, then applying the proper paint and primer will be your best chance at a successful and long-lasting outcome.
