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.

Keep this wood treatment in its original container. Tin should be tightly closed and stored in a safe well ventilated place away from sources of heat and ignition.

Looks great and lasts for a few years by Paul F

This wood preserver has helped keep my fence looking good and slowed down the breakdown of some parts of the wood. Unfortunately, before I moved to my home the fence had not been treated for more than 5 year, so some rot had already begun to set in on the parts where the water stays on the surface. The preserver forms a good waterproof barrier and appears to help prevent the rot spreading as fast as I had expected it to. I treat the fence every 2 or 3 years, which keeps it looking almost new, with only a bit of fading after 2 years. Definitely recommend this for a long lasting and reliable finish, just remember to shake well for a consistent colour.

Great Product by Nigel Haire

I didn't want any of that namby pamby water based stuff and had to have something that you could apply to non Rough Sawn timber. So I chose this. Brilliant. Goes on really well and I used less than I thought I would. Usually the coverage given on the tin of paint needs to be taken with a huge pinch of salt, not this one though. I managed to buy twice as much as I needed on the strength of the coverage details. All good because I now have enough for another 3 coats in a few years time. It was also a fair bit cheaper than B&Q.

Excellent product by Andrew Bedford

Easy to apply and creates a good solid colour which looks like it will seriously extend the life of the shed. Be careful to follow the instructions and read the cautionary notes on side of the tin. Product delivered very promptly.

Great Product by Philip Kettlewell

Great product, would not buy any other preserver product, only small problem being I wish there were a pouring nozzle, it can become a little messy, if one is not careful, but it would not stop me buying more of these Roonseal preserver products.

Product is solvent based and two coats gave very good coverage. First time I have used this product and would highly recommend it, much superior to water based products.

Pleased I found it by P NUTTEN

I've always used Cuprinol, but their product no longer contains a preservative, so I was pleased to find this alternative. Easy application, early signs are that it's a very effective waterproofer, but even the light brown gives a quite dark finish.

Bad by Mr B M Kilcullen

Having problems with product. Colour varies quite a lot as you start using it from the can. Even after shaking the can there is what I can only describe at sediment in the bottom of the can. Used this product before and it was great but the product I now have I would not use again. Boughy light brown but as you use the can it turn's nearly a green colour. Only option now is to paint all the fence again on a dark colour so it does not look like a botched job. Must have a dodgy can. Not worth complainging to ronseal as you get now here with this big coporate companies. I bought 4 can of this stuff hope the other 3 cans are the proper stuff

A note from us...

Hello Mr Kilcullen,

Its disappointing to hear when customers do not have the best experience with one of the products that we supply. I can tell you that there has been a formulation change with the Shed and Fence Treatment this year that has resulted in some colour variances from the old treatment. The change is due to regulations around specific chemical ingredients in all preservatives and many manufacturers have had to make some changes. I would be happy to discuss further if you would like or if you have any further problems with the other tins. You can email on or call and have a chat with one of our friendly advisers on 0800 7818 123.

Kind regards Sam.

Very good service and protect by Thomas Taylor
