Cuprinol Exterior Wood Preserver is suitable for the treatment of most exterior wooden surfaces including structural greenhouse timbers and timbers in close proximity with plants (not seed boxes). Extra thorough drying must be allowed under service conditions before introducing plants.
For interior timber, consider Cuprinol 5 Star Complete Wood Treatment (WB).
Looking for a clear exterior wood preservative? Consider Cuprinol Wood Preserver Clear (BP).
Ensure that all wooden surfaces to be treated are clean, dry and free from surface dirt, debris and other surface contaminates.
Always do a test area before starting any project to test appearance and suitability of the product on the timber to be treated. 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 Bee keeping 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.
For best coverage and protection, three coats are recommended.
To maintain the surface finish and its protective properties, re-apply a fresh coat of Cuprinol Exterior Wood Preserver as and when required, following the preparation and application instructions.
In an exposed coastal area I've tried numerous other products on a selection of different types of wooden sheds. Cuprinol has proved to be the best product I have found to protect and waterproof the exterior of the sheds.
Leaves a decent finish - but when you fist apply it dos go on a rather strange colour!
I was recommended this product from my local building company when they were building a wooden garage, next to my stable block. The application is so easy, stir and apply with brush or roller onto new treated wood, and it goes on like water. Fantastic, fast coverage and weather dependant, dries quickly ready for the next coat. 5 litres goes along way, and I now use it for all my various benches, garden tables and chairs. It darkens on the second coat, and you can see its water resistance when raining.Incredible product, and pound for pound, fantastic value. Quite simply if it was ever discontinued, I'd be lost.
See review of the same product in Rustic Green.
Having previously used the solvent-based Cuprinol Wood Preservative on Siberian Larch cladding when the time (eight years) came to re-treat the boards I was concerned to learn that the product had been replaced with a water-based preservative. However, having now carefully prepared the surface and applied three coats of the new treatment, I am very impressed with the results. We shall be interested to see how it withstands weather over the next eight years!
Repelled rain well
I always use this product as its a great price and does the job just great
Cuprinol is a good manufacturer of outside coatings, and I am very pleased with the colour and finish.
Good coverage water based preservative - the chestnut comes up pretty dark - darker than you might think and if painted on liberally can be almost black. Looks great, easy to clean - you must keep it stirred though. You can spray paint with it despite what it says on the tin...
I have never had a bad experience with Cuprinol products. Provided you pick the weather and re-coat in the time frame stated on the tin then the job will always go well and you should have a top class finish that lasts for years. The black looks superb on rough finished timber clad barns and outbuildings (feather edged board) and gives a nice finish without too much shine.
I by mistake ordered the water based version of this preserver. I was half way along the fence with the spirit based version. The colours were so different that I ordered another can of spirit based. Both were labeled acorn brown. Otherwise easy to apply and clean up (used in on side that did not show).
Very poor choice Water based products do not penetrate . I had to buy solvent based product to achieve full penetration of the wood
Easy to apply and soaks right into the wood and retains it's colour for many years before it starts to fade!
Very good coverage and colour. Gave exactly the finish I wanted.
Great product. A bit concerned when it appeared grey when applying but dried to a rich black. Perhaps Cuprinol should consider stating this on the tin.
