It can be applied to rough, sawn and smooth timber solvent based product can be brushed or sprayed (although a spray system that is suitable for solvent based materials needs to be used).


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

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.


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.

Very easy to apply with brush
I managed to cover 2.5 double sided wooden 6x6ft panels per 4L tin.

Penatrates the wood well.
I bought this as I'm not impressed with water based products I have used in the past. As we have just bought a new summer house it makes sense to spend a little more and get a product that will protect it fully. So far so good, it goes on well with a brush no need to spray and it penetrates into the wood very well leaving a good rich colour.

Easy to use and soaks into the wood to provide the preservation needed
A great product which is very easy to use and provides great looking finish plus you know the wood being treated is going to be well preserved

Excellent product.
I've just given my new shed the recommended two coats of this product and I'm very impressed. It goes on easily, covers very evenly and is a really nice colour, and pretty much the same colour it says on the tin! Coverage wise, my shed is 14x10ft and one 5L tin was just enough for two coats.

Good & Bad - Good from Woodfinished direct, bad from B&Q ?!
Bought 2 of these from B&Q and pigment or sediment had settled in both tins causeing dark brown sludge to come out when poured, dyeing the fence I was treating dark Brown. On the other hand, the same product bought from WoodFinishes Direct was faultless. That goes for the service, website help & info, delivery, and price. Everything was totally satisfactory. Top job. In balance, Ronseal replaced and compensated me for the faulty product. All good. Jem :)
