Ronseal Shed and Fence Preserver can be used as a stand alone treatment or as a pre-treatment. For added protection, It can be over coated with an exterior wood or decking oil such as Ronseal Decking Oil.

Take a look at our blog post on garden shed maintenance, where we go into some of the finer detail behind keeping your shed in good tip top condition.

New Bare Timber

  • Ensure all wooden surfaces to be treated are clean, dry and free from dirt and debris

Previously Coated Timber

  • Any surface coatings such as paint, varnish or stain must be fully removed and sanded back to bare wood

Old Timber

  • Wood that has become decayed should be removed and replaced
  • Cut out and burn all decayed wood at least 45cm beyond the area of damage
  • Brush down the wood with a stiff broom or brush to remove any ingrained surface dirt
  • Traces of mould, algae or fungi must be removed with a stiff brush or scraper
  • Areas that have been affected by mould, algae or fungi should be treated with fungicidal wash prior to application of Ronseal preserver

Always do a test area before starting any project and follow the manufacturer's instructions on the tin at all times. Shake or stir well prior to and during application to ensure a consistent colour. Avoid contact with bitumen, bitumen felt, mastics and plastics.

  1. Ronseal Shed and Fence Preserver can be brush applied or by dipping the timber into the product, and can be spray applied with a suitable solvent spray system and safety equipment
  2. Where possible, end grain should be dipped or given extra coats to ensure the best possible protection
  3. Apply 2 coats for eradication of woodworm in roof joists, floorboards, joinery and small timbers; 3 coats for eradication of dry and wet rot and insect attack in existing or replacement timbers
  4. Allow 24 hours drying time between coats

Once dry, a suitable exterior wood oil or stain can be applied. Always follow the manufaturer's instructions on the tin.

Wood treated with Ronseal preservative can be easily maintained by applying a fresh maintenance coat on a yearly or 2 yearly basis as required.

Please note: If this product is over-coated with a clear decking oil, it will last for around 5 years. This is only if the decking oil is re-applied and maintained on a yearly basis.

A note from us...

Hello Anne-Marie,

It wood be fair to say that many of the Preservatives are quite watery in appearance and can be a little messy during application. They are designed to soak into the surface of the wood and protect. If you would like any advice on application please feel free to call and speak to one of our advisers on our free phone number 0800 7818 123

Kind Regards

The best priced quality preserver for our field fencing and gates by J L C

Having tried other comparable branded products, which were very watery or not tough enough to protect from the outside as well as preserve from the inside this was the best one in terms of price and coverage. This colour was much better once settled and on the wood than the other options for our gates and field fence. Thank you for price matching and discounting for one batch delivery as this made a difference to us due to the quantities we required. Your customer service was extremely efficient and reliable swift delivery on the several occasions we have ordered. Thank you.

Very good - excellent by Rybicki

As this has only recently been used my comments are based on my short-term knowledge of the product. I purchased this as a preservative rather than a wood stain. You need to shake the tin well to mix it and then transfer it to a container for applying. It applies well and I am hoping after having applied 2-3 coats that it will help to preserve the timber rather than just stain it. I have used it on railway sleepers (that we have as part of our landscaping). The coverage is good and so far is not slippy when walked on following rain (one of the bonuses) and I hope that in the long term it will preserve and retain it's colour (dark brown). Very happy customer.

Considerably cheaper than leading diy retailers Arrived next working day by ALAN NEWBERY

I have used this product over the last five or six years. It beats any others tried. Soaks into the wood , rather than just coating the surface.

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.
