  • Overview


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.

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.

Brilliant! Turned my tan coloured fence into a beautiful dark brown!!!
My builder painted my fence with Ronseal 2 in 1 TAN colour but I wanted it dark brown! Wood-finishes came to my rescue again and said that I could use dark brown presever to change the colour to dark brown!! Worked brilliantly

The wood preservative worked exactly as described

Very good product
Good coverage, liquid is very thin and could be messy if care not taken. Smell not as bad as some reviews suggest. Would use this again

Did the job! Easy to use, looks good.
Buying Ronseal preservative was my first order with Wood Finishes Direct, and now no need for me ever to buy such products from other well-known retail outlets - the Ronseal from Wood Finishes Direct was 25% cheaper than from B&Q, with free next day delivery; excellent service, with order confirmed by e-mail, and delivery tracked with e-mail and sms text message updates - it's great (and very rare these days!) to see such efficient and 'customer-friendly' service!

Easy to apply-does what it said.
Easier to apply than I expected.Previous reviews suggested necessary to frequently keep mixing.I found to store before use in an upside-down position-then a good stir was O.K.Clour match(light brown) was good.

Excellent product at a great price!
I ordered six 5L tins to cover twelve fence panels (both sides) and a 12'x8' shed. The product went on easily and covered well, and is much better than the usual water-based "sit on the surface" rubbish. I'll order some more next year for a second coat which should see me through for a few years before another coat. The price was great - at least £5 cheaper per tin than the high street / retail park stores.

Nice, natural colour, easy to paint on and wood finishes direct is the cheapest place I've been able to get it from.

Excellent product
This is a great product but really is impossible to apply by brush, it doesn't hold at the end of the brush, even thick high quality block brush won't hold it well. I did the inside of the shed with the brush first and it was a nightmare. Switched to applying it with a microfibre cloth and it was a doddle. Excellent coverage, perfect colour, dries very evenly and I can see that rain will bead up on the wood rather than soak in after just one coat! Brilliant!
Ian Howick
Not dense enough
could not achieve black density -- seemed too dilute
Our feedback:-

I am sorry you were not satisfied with the colour. Wood Preservers tent to be of a watery consistancy so that they can penetrate the substrate. If ou require a finish that is more dense I would recommend an Opaque wood finish.

Excellent Product
Does everything in one. Very good penetration of the wood and good colour. Really enhances the beauty and presence of my log cabin.
Brian Leeming
Far too 'runny'.
The company putting it on my fence has had difficulty persuading their staff to use it, as it is so messy. Retention is poor on surfaces that have been treated previously, whereas it is rapidly absorbed into new wood resulting in a very low density colour. This means that the amount that I have needed to buy is at least twice what the estimator suggested. I'm going to need a third 5 litre can to complete the job, whereas the estimate was less than 2 cans. I won't ever buy it again.

Don't hesitate - buy it!
I can't recommend this product enough - really impressed with ease of application and resultant finish, 15 year old shed looks almost brand new.

Very good product at a vey good prriceprice
I used this on my new timber workshop before I erected it. The timber was planned and had a base coat when the it was made. The preserver went on very easily but be careful as it will splash. Coverage was as stated on the tin and 2 coats was fine but I put 3 on as I had plenty of material and 2 sides are difficult to reach once the workshop is erected. Just one thing and that is to give the tins a really good shake every time you use them as the preserver seems to go thick at the bottom and thin at the top after a couple of days.
