Barrettine Universal Wood Preservative is the perfect undercoat for most exterior projects. This product does not contain wax which makes it ideal as a pre-treatment for water-based wood finishes such as Barrettine Country Cottage Shades.

Looking for a wood preservative with added wax, for better water repellency? Try Barrettine Premier Wood Preservative.

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

New Bare Wood

  • If required, new bare timber can be cleaned and de-greased with white spirit prior to application

Previously Treated Wood

  • Any surface coatings such as paints, varnishes and stains must be fully removed back to clean, bare wood by sanding or using a suitable product stripper / remover
  • Exterior wood that has been oiled in the last year should be allowed to weather for at least one year or until the wood preservative is able to penetrate through to the timber

Old Untreated Wood

  • 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 and debris
  • 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 Barrettine Mould and Mildew Cleaner prior to application

Always do a small test area to confirm performance and compatibility before starting any project and follow the manufacturer's instructions on the tin at all times. Protect any surrounding soil, plants or aquatic environments from splashes of Universal Wood Preserver. Ideal application temperature is between 10-30℃. Wood should be frost-free when treated. Shake well prior to use.

  1. Apply using a synthetic brush designed for solvent-based products
  2. Spread the preserver thinly and evenly, ensuring end grain is thoroughly treated along with cut and drilled areas
  3. Apply 2-3 coats, allowing 6-12 hours drying time between coats

Please Note: Low temperatures, increased humidity and ingredients of some wood species may increase the drying time up to 24 hours.

Once fully dry, this product can be over-coated with a suitable wood oil, paint or stain.

Wood treated with Barrettine Universal Wood Preserver 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 or other exterior wood oil, it will last for up to 5 years. This is only if the exterior wood oil or decking oil finish is re-applied and maintained on a regular basis as per the guidance on the relevant product.

Q. Is this all I need to protect my summer house?

This product is commonly used on its own on sheds and fences and other exterior items constructed of rough wood, however for a total treatment we would recommend Log Cabin Treatment for added water repellency and weather protection, or Osmo UV Protection Oil Extra to also reduce the likelyhood of your log cabin from greying.

Q. Can I use Barrettine Wood Preservative on a chicken shed and dog kennel?

Barrettine Wood Preservative is perfectly safe to use on any surface that comes into contact with animals when dry. This includes but is not limited to dog kennels, chicken sheds and houses, horse stables and more. It's important to remember that this wood preservation treatment should be over-coated with a suitable exterior oil. Animals should only come into contact with the surface of the wood when both the wood preserver and oil have fully dried.

Excellent stuff - goes a very long way by Steve Batchelor

I used it as a stain and preservative on a set of windows I was making. I had the advice from Wood Finishes Direct and now know it contains a fungicide which will help the life on the windows. Excellent product, goes a very long way and will stay as part of my finishing product range.

A good product so far time will tell by Peter Carter

I gave the outside of my shed a couple of coats and the inside just one coat at present. On a 10x8 shed, soaked in well. Very little aroma. Will be top coated with a wood protector, also from wood finishes. Will do this every couple of years.

A super product delivered speedily by Frankie Reid

Very easy to apply. A little runny but fine if you start at the bottom of each wall. Work systematically as it is very clear! Soaked in and dried well.

Goes on easily and not unpleasant to work with by Catherine Dow

This product soaks in well and is easy to apply. If it does what it says I will be happy to use again. Has only been applied in the last month, so too soon to tell.

Spirit based, Flows easily Does not contain any wax - perfect for different top coats by Ian Taylor

Used this clear, spirit based, wax free product to protect a log cabin from rot and insect infestation. Viscosity very similar to water so recommend wearing hand and eye protection especially when coating items at/above eye level. Does not contain waxes so a top coat of paint/varnish etc is required. Smell not too overpowering compared to some other preservatives. Product easily cleaned from synthetic brushes using white spirit. If you do not want to use a top coat, use Barrettine Premier Wood Preservative

Good product by Kevin G

Absorbed 2 coats well, and seems to repel water afterwards but still accepted a cuprinol shade topcoat afterwards, which is want I wanted. Shed looks great, and should hopefully last now as well. Rapid delivery from Wood Finishes Direct, all good!

Excellent by Pete

Goes on easily, I did one coat on a complete front door (front and back) with about 200ml, or 1/5th of a 1 litre can so the coverage does seem understated, i.e. it seems to go further than the manufacturer specifies, but no complaints it does exactly what it says it does
