Cuprinol Ultimate Garden Wood Preserver is a coloured wood preservative with an advanced formulation, designed to colour, preserve and protect all types of garden wood for up to 5 years.

Looking for an alternative wood preservative for garden wood? Try one of the following products from the Cuprinol range:

Product Use
Cuprinol One Coat Sprayable Fence Treatment A water-based, sprayable wood treatment for garden fences and sheds which colours and protects rough sawn timber
Cuprinol Shed and Fence Protector A protective wood treatment for garden sheds, fences and all rough sawn and smooth planed garden wood
Cuprinol Exterior Wood Preserver A water-based exterior wood preserver for use on sheds, fences, cladding and all sawn wood
Cuprinol Wood Preserver Clear (BP) A clear, multi-purpose wood preservative for interior and exterior use on all sound timbers, including structural timbers and joinery

Ensure that surfaces to be treated are clean, dry and free from dirt, debris and other surface contaminates.

Bare or New Timber

  1. If necessary, brush surfaces with a stiff brush or broom before treating to remove any loose surface matter
  2. Areas affected by mould, algae or fungi should first be treated with a suitable mould and mildew cleaner prior to application
  3. All rotten timber must be cut out and replaced
  4. If the wood surface is looking worn or has greyed from sun damage and the effects of weathering, Cuprinol Greyaway Restorer or Cuprinol Garden Furniture Restorer can be used to revive the wood before coating
  5. Any holes, gaps or splits in the surface of the wood can be filled with Cuprinol All Purpose Wood Filler or Cuprinol Ultra Tough Wood Filler
  6. Bare or untreated garden wood can be pre-treated with Cuprinol Wood Preserver Clear (BP) prior to painting if required

Please Note It is important that any wood preservative used does not contain wax, oil or silicon as these will penetrate the wood and repel any water-based product that is applied on top.

Previously Coated Timber

Existing surface coatings such as paint or varnish must be fully removed back to bare wood before using Cuprinol Wood Preserver by sanding or using a suitable wood stripper.

Always do a small test area before beginning any project to check suitability and compatibility. Follow the manufacturer's instructions on the tin at all times.

Do not apply if rain is likely before the product has fully dried. Stir contents of tin thoroughly before and during application to ensure a consistent finish.

  1. For best results, apply Cuprinol Wood Preservative with a Cuprinol Woodcare Brush
  2. Apply a minimum of two even brush coats to give a uniform finish
  3. Apply evenly along the wood grain, avoiding splashing of surrounding plants, brickwork, glass, PVCu etc
  4. Any splashing should be cleaned up immediately (whilst still wet) with water and household detergent
  5. Excessive spillage on plants should be rinsed off immediately before drying
  6. Allow the previous coat to soak in before applying the next
  7. The preserver usually dries in 2-6 hours under normal weather conditions
  8. Where a strong colour change is desired, more coats may be required
  9. Recoat within 2-3 days of previous coat. If a longer period elapses, do a test area to ensure product is not repelled

Please Note: If using more than one can it is advisable to mix them together in a larger container or finish painting in a corner before starting a new can.

Regular Cleaning

Surfaces treated with Cuprinol Ultimate Garden Wood Preserver can be cleaned at regular intervals with a dampened, lint-free cloth or Cuprinol Garden Furniture Cleaner.


If being used as a stand-alone treatment and not being over-coated, this product can be easily maintained. To maintain the surface finish and its protective properties, simply apply a fresh coat of Ultimate Garden Wood Preserver as and when required, following the Preparation and Application instructions above.

Great product by JON GRIFFITHS

Definitely worth paying the premium for a decent coating and have it last longer. It’s a false economy using inferior products then having to redo them every 12 months. This is by far the best I’ve used and I would definitely recommend.

Very pleased - easy to apply by Mr K Tancock

Much better than other pigmented preservatives. The ultimate range though rather more expensive than others gives greater coverage than many I have tried. The colour seems to last longer and has fade -proof qualities

Covers well by Mark Bowhay

Good penetration although this results in some splatter and mess. Seems superior to most cheaper fence products. Colour is a little dark. In visible areas I have used as a preservative undercoat and overpainted with Forest Green in other product ranges but under trees the darker spruce green 'disappears' and works well. Only concern is high cost charged by Cuprinol.

Looks excellent by Brian Hardy

Good coverage, easy to apply (by brush), looks excellent. Be aware that the wax component means that the second appliccation has to be applied soon after the first.

Easy to use and clean up but too soon to tell if it will be as durable as the previous solvent based product by Philip Elswood

Good product that covers well and dries quickly. being water based brushes clean well with lots of soaking/rinsing. Sold at a really competitive price and very quickly delivered

Good product by Michael Brown

Went on well and one coat wood have been sufficient for my new shed. However decided to do two coats and there is still enough left in the tin to do another one or two coats on my 12' x 7' work shed when it needs. Nearly bought two tins by mistake so glad I didn't.

Superb preserver by Mike

Have been using this preserver on all my fences and sheds for some years and wouldn't change. Very easy to apply, goes a long way and is a great colour.

Reviewed 4L, Spruce Green on: 23/09/17

Paint is very thin so you need to be careful to load brush properly to avoid dripping. I applied second coat when the first coat was still slightly tacky for a perfect finish. I also used this paint on my shed two years ago and it still looks like it has just been painted. Highly recommended, probably the best product of its type on the market.

Easy to use, looks great by Christina Welch

I was very pleased with Cuprinol's Ultimate Wood Preserver as it was easy to paint onto our shed and dried to a good overall colour without streaks or blotching. It was absorbed and dried quickly and has made our old shed look like a new one - and that was just one coat! The Spruce Green colour looks very natural amongst the trees and shrubs, time will tell how long it will last but at the moment it is looking pretty good. Very pleased with this product.

Excellent cover and finish to the wood cladding on my house by Joanne Wardale

I have used Cuprinol Country Oak for years as it is the perfect colour for the wood finish at the top of my house. There used to be a solvent based product but now it is water based with a wax finish. I was dubious at first but did not want to change the colour or product due to its long lasting finish. I have recently used the new water based waxed finish and am extremely pleased with it. Equally good finish, and easier to clean the brush by just rinsing in a bucket of water. On to the fence now!
