How to buy the best decking stain

The finished effect

Not all deck stains are created equal, and there are a few formulas and finishes to choose from based on the effect you’re after. In terms of looks, a translucent deck stain is an option for those who want to let the natural grain of the wood shine through, while those after a more deliberately painted look should opt for a solid finish.

Water- or oil-based?

The other choice is whether to go for a water-based or oil-based decking stain; both do a good job of locking out damaging water and UV rays, but water-based has the slight edge on eco-friendliness, so that’s something to consider. Our top water-based decking stain overall is (again) Ronseal’s Ultimate Protection Decking Stain, which testers found easy to apply, and which dried to a wonderful translucent finish that stood up to harsh weather and footfall.

This water-based decking stain from Ronseal is designed to penetrate deeper into the wood than others, making for better adhesion and, as it says on the tin, ultimate protection.

 Best durable decking stain: Sikkens Cetol HLS Plus Translucent Woodstain

2. Sikkens Cetol HLS Plus Translucent Woodstain

Best durable decking stain: beautifully glossy and lasting an age, this is our best deck stain for a durable finish

Best for: Translucent gloss
Volume: 2.5ltrs
Drying time: 4-6 hours
Colours available: 8+
Reasons to buy
+ Use as a base or top coat + Extremely long lasting 

Whether used as a base stain or a top coat, users say this Sikkens wood stain more than earns its near-legendary status among decking devotees. They say it sinks in quickly and forms a solid foundation as a base, and leaves a wonderful glossy finish, as well as a water-repellent, anti-mould, anti-algae and UV-resistant protective layer as a top coat. Best of all, perhaps, reviewers found it lasted an age, with one homeowner who lived in an exposed location claiming it only needed re-coating an astounding seven years after the initial staining. For its proven hardiness, it looks to be a great bet for high-traffic areas and variable weather.

Best anti-slip decking stain: Cuprinol Anti-Slip Decking Stain

3. Cuprinol Anti-Slip Decking Stain

Best anti-slip decking stain: stop sliding with this grippy, non-slippy deck stain

Best for: Weather-resistant
Volume: 2.5ltrs
Drying time: 2-6 hours
Colours available: 13+
Reasons to buy
+ Anti-slip for safety + Durable weather protection 

While the effect this semi-transparent deck stain gives is an undeniably elegant one, make no mistake – it’s made of tough stuff. The anti-slip formula is ideal for decking that sees a lot of foot traffic, especially from fast-moving children and pets who could get into scrapes, but it does double duty as a hard-as-nails durable layer too. The double-action formula of anti-slip microbeads and algicide keep things grippy while preventing the formation of unsightly mould, and protects against weathering and scuffs too. A great choice for busy gardens.
