Overview

Cuprinol Exterior Wood Preserver is a lightly tinted, water-based wood preservative treatment suitable for most exterior wood, including structural and timbers in close proximity with plants (not seed boxes). Extra thorough drying must be allowed under service conditions before introducing plants.

Please note: Cuprinol advise that the 'black' version of this product is actually a dark grey. Please check colour suitability before starting any project.

Preparation

Ensure that all wooden surfaces to be treated are clean, dry and free from surface dirt, loose debris and any other surface contaminants.

Bare or New Timber

Previously Coated Timber

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

Application

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

Please Note: Cuprinol Wood Preserver is not suitable for use on beehives and other beekeeping equipment. Timber treated with this product will not be suitable for paint, varnish or wood stain finishes. The colour of treated wood may be affected by type and condition of wood and may be modified by previous treatments.

This product is not suitable for spray application. Shake or stir thoroughly before and frequently during use to ensure an even colour.

  1. Apply 2-3 coats or Exterior Wood Preserver with a suitable brush, in the direction of the wood grain
  2. Allow 4 hours drying time between coats
  3. For best coverage and protection, three coats are recommended

Aftercare

Maintenance

To maintain the surface finish and its protective properties, simply re-apply a fresh coat of Cuprinol Exterior Wood Preserver as and when required, following the Preparation and Application instructions above.

FAQ

Can I over paint my previously Ducksback coated shed with this? Ducksback was very good but wondered if this product may be even better?

Cuprinol Ducksback is very heavily wax enriched and is designed to repel liquids. For this reason, you would not be able to apply the Exterior wood preserver over the Ducksback until all of the wax is removed and liquid no longer beads on the surface.

Will the Cuprinol Wood Preserver seal and stop fences turning green? We're having to paint our fences yearly because they keep going green.

This will prevent new growth of algae & mould but any biocidal growth that is already present needs to be cleaned with a strong multicide such as the Cuprinol Decking Cleaner before application of any new product. The problem will continue to persist each year otherwise.

Good but not as good as earlier product

Difficult to pour even into a funnel & looks a funny colour. Very runny when put on fence, but dried quickly and a good colour match. Not as good as previous oily product but we now live in a water based era.

You paint it on a fence

Makes the fence look better since it has not been painted for several years

Use it regularly

Although the ‘original’ Golden Brown was much lighter, the fence needs a face lift so happy as product is quality

Good for giving an old shed a face-lift

I used it to smarten up an old shed that had lost a lot of its original colour and protection. It was easy to use and I’m pleased with the result.

Arrived so quick with excellent customer care

I bought this one to use on the shed, bench and decker. This company is very good to follow up with the order from beginning to end even ask the customer is happy after sold it, this is all the business should be but no many like this company nowadays. The price is also good. A very happy customer and will recommend to others and buy again from them when need.

Bought Cuprinol Acorn Brown wood preserver for fence. Happy with the colour. Too early to say if it is durable in protecting the fence, but so far very happy with the product.

Cuprinol is a fine wood preserver

I have used Cuprinol fence preserver many times and it certainly does what it says on the tin and the colour enhances the panels

Great product. Easy to apply and long lasting

Asy to use and gives a beautiful finish to garden furniture and fences

The paint is easy to use and looks good when applying the recommended 2 coats. The colour becomes stronger and more even with a third application, but the structure of the wood still shines through. Because it is water soluble, brushes etc. are easy to clean after use.

Easy to apply, used golden brown, gives a lovely finish to new timber.

I have a cheap B&Q small wooden shed from 30 years ago and the wood is still good. Excellent product.

Quality seems great, ease of application too.

Went on well and looks really good on the summerhouse. With the decking oil on top the water just beads and runs off.

It does exactly what it says on the tin

I have to admit, I bought this same product in 2021 and I am going off my experience then, as I have not started to use the product yet due to adverse weather conditions. I am hoping to use it when the weather becomes more drier and settled.

Very good

I would like to leave a review, but the weather has been so bad I haven't had the opportunity to use the product. However I have used this product some time ago and it ticked every box.

J
James Beeley
It is a very good product and have used it for years to protect my outside shed.

What can I say in that it does the job I want it to do and that is protect my wooden shed and at the same time makes it look good which pleases me.

Early days, but looks OK

I had intended to buy a clear coloured wood preservative, but the Cuprinol Exterior Wood Preserver is opaque and slightly waxy. It was easy to apply and appears to absorb well into the wood. You cannot tell that the product was opaque once the preserver dries. Will see how good it is in coming years - hence no 5 stars.

Jon Manning
More light brown.

This is a good water based product so easy clean up but its not very golden. If you want golden then the Barritine fence preserver is great and feels easier to put on and soaks further. This cuprinol is more light brown than golden. Nice enough,

Nicolas Robinson
Have used this several times. It is effective and we keep coming back.

We like the colour and is worth the effort of putting on.

Not the easiest to apply, but definitely long lasting

Have been using this product a few years, fences, garden sheds which I found using “ordinary fence, shed paint” needed to be done every year, use Cuprinol Exterior Wood Preserver and they only need done every 3>4 years

Great finish easy to apply

Finished off painting my fence with new water based Cuprinol wood preserver, Excellent match for the previous chemical based product. Goes on well and easily. Probably spreads further than the old product. goes on light grey but dries chestnut. Excellent waxy finish.
