This specially formulated wood preservative gives long lasting colour and protection to sheds, fences, trellis and other rough sawn and smooth planed timber around the garden.

Note: Although Ronseal Shed and Fence Preserver will help to prevent woodworm in the first place, it will not cure existing infestations. To kill existing woodworm infestations, use Ronseal Woodworm Killer.

How do you prepare your garden shed for preservative? What is the best wood treatment? How often do you apply it? All questions that we hear on a regular basis. Take a look at our blog post about garden shed maintenance, where we go into some of the finer detail behind keeping your shed in good tip top condition.

Ensure all wooden surfaces to be treated are clean, dry and free from dirt and debris. Areas that have been affected by mould, algae or fungi should be treated with Fungicidal Wash prior to applying Ronseal shed and fence treatment. Any surface coatings such as paint, varnish or stain must be fully removed.

Wood that has become decayed should be removed and replaced prior to the application of Ronseal shed and fence treatment. Cut out and burn all decayed wood at least 45cm beyond the area of damage.

Always do a test area and allow to fully dry to assess product suitability and final colour before starting any project. Follow the manufacturers instructions on the tin at all times.

Ronseal wood preservative must be well shaken or stirred prior and during application to ensure a consistent colour.

Ronseal Shed and Fence Preservative can be brush applied or by dipping the timber into the product. Wood preservative can be spray applied with a suitable solvent spray system and safety equipment. Where possible, end grain should be dipped or given extra coats to ensure the best possible protection.

Ronseal Shed and Fence Preservative should be given 24 hours drying time between applications if additional coats are required.

Avoid contact with bitumen, bitumen felt, mastics and plastics.

Clean brushes immediately after using this wood treatment with White Spirit.

Decent quality wood preserver by Mr McCarthy

I have used this product for several years now, and it seems to do the job. Easy to apply with consistent quality and value for money compared with alternatives.

Easy to apply by C Cope

Provides good coverage but doesn't seem to last for as long as it says. Probably something to do with the prep we do beforehand.

It seems to do what it says. Time will tell how good the preserving quality and the colour fastness.

Very good product by David Lawrenson

I bought 5 tins of Ronseal Shed and fence preserver. Very happy with the product. The colour, and the texture of the preservative was excellent. It was easy to use and soaked into the wood so I'm confident my fences panels will last many years.

Good product, but second can isn't colour advertised! by Joshua Dunn

I was happy with the first light brown colour of this paint ordered. However, after ordering a second to finish off my section of fencing it has dried a much darker colour as if it was placed in the wrong can. I now have to repaint what I have already painted so that they match. Not happy as garden is much darker than I wanted and will cost me another day of painting!

A note from us...

Hello Mr Dunn,

Ronseal changed the Formula just before Christmas last year. Unfortunately the Light Brown has been effected and is a slightly different shade as stated in our overview "New improved formula for 2016 provides protection against wood discolouring fungi. New formula consistency and colour shades may vary to the old formula." My apologies for the inconvenience caused.

If there is anything further that I can help with please do let me know.

Kind regards Sam.

The perfect dark brown Matt finish I was looking for by Colin Gunn

A great finish but a bit more tin shaking than I expected to keep constant colour throughout job. Dark brown a great look although quite expensive if you follow the three coat recommendation. I think two coats is enough.

Excellent product!! by Wendy B

I've used this product several times before in a different colour and despite being quite an environmentally-friendly lass, I just can't bring myself to use non-solvent based wood preservers - anything else I've tried is just hopeless. This stuff on the other hand soaks in really well, and so as well as preserving the wood, means the colour lasts a lot longer than water-based surface products. A couple of coats is enough to give a decent depth of colour. Was chuffed to find this available from the wood finishes website - I'd never managed to track down this product in black before.

Shed and fence protector by Maria Mirley

Painted this on my summer house and with having a fairly small garden, I thought the light colour would look best. So pleased with the results and the way it went on so I'd definitely recommend it.

Variable results and messy product by Carol Smith

Good absorption and finish on old rough timber but I found it hopeless on planed timber regardless of how long the timber had been aged - the product just sat on the surface and left a sticky residue. The product also drips everywhere, so it is very messy and wasteful in use without great care in applying it.

A note from us...

Hello Carole,

Thank you for taking the time to review this product. Although the Shed and Fence is suitable for rough and smooth wood, I would suspect that it requires a much thinner application on the smooth wood in order for it to absorb well. You may find that the sticky residue was due to a slight over application and the product taking longer to dry. I am happy to answer any questions you may have if you wish to discuss further, you can email me at

All the Best Sam.

Arrived on time, does what it says on the can by Brian Jowett

Have used this product before. This latest version has more colouring pigment and covers well. Used on new unpainted fence (18 months old) and absorption was much more than expected and allowed for in calculating quantity needed. Would buy again but ignore coverage claimed by manufacturer.

Expensive but good stuff by David

I used this product a couple of year ago to treat a fence which had been neglected and was showing some early signs of rot. A couple of coats produced a good finish and I'm still pleased with the result. The preservatives which it contains help to prevent rot and eliminate woodworm. Cheaper, coloured water repellents are OK for wood in good condition but this stuff is probably better for older wood in need of attention. It is expensive but you get what you pay for. I bought this latest tin for similar projects.
