Barrettine Premier Universal Preserver - Safety Information

Overview

Barrettine Universal Wood Preservative is the perfect undercoat for most exterior wood projects. It's deep penetrating formula protects against wood boring insects, wood rotting fungi and blue stain.

It provides a clear finish for a variety of top coats. Can be used on un-treated wood or treated timber outdoors and also used on window frames, external doors and frames. Can also be used on structural timbers on indoor, unoccupied areas such as floor joists.

This product does not contain wax which makes it ideal as a pre-treatment for water-based wood finishes including varnishes and paints.

Preparation

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
Freshly cut sawn ends should be thoroughly treated with either Universal Wood Preserver, or alternatively Ensele End Grain Preservative

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
Any existing cases of woodworm can be treated with Barrettine Premier Woodworm Killer
Fill any gaps or splits in the wood with a suitable wood filler

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.

Apply Universal Preservative using a synthetic brush designed for solvent-based products
Spread the preserver thinly and evenly, ensuring end grain is thoroughly treated along with cut and drilled areas
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.

Cleaning Equipment

After use, paint brushes can be cleaned with Barrettine Brush Cleaner or Barrettine Paint Brush Restorer.

Finishing

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

Aftercare

Maintenance

Wood treated with Barrettine Premier Universal Preserver can be easily maintained by applying a fresh maintenance coat on a yearly or 2 yearly basis as required.

F.A.Q.

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

Although this product can be used as a standalone treatment for summerhouses sheds, fences and other rough sawn or smooth timber structures, it has minimal durability and does not provide any weather protection for the wood. For a more durable finish and one that provides added water repellency and weather protection, we highly recommend that this product is overcoated with a suitable exterior wood oil such as Barrettine Log Cabin Treatment or Barrettine Decking Oil.

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

Barrettine Wood Preservatives are 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.

Say to apply by Allan Cowan

I cannot say how well it works until some time has passed and the wood either survives or rots. Come back to me in three years or so.

Seems to have done what I wanted it to do by Max Johnson

I had intended to use this product on a new, tanalised double driveway gate (that because I live by the sea is exposed to a lot of high winds and rain, plus salt and sand abrasion). But then realised that I needed to use Wood Protective Treatment instead. So I haven't used the product yet! However, when the weather improves I shall happily use it on some surrounding fencing with the added advantage that it will match the colour of the gate. The Barrattine wood preserving treatment seems to be doing a very good job, my only possibly adverse comment being that it was still 'in the air' after a couple of weeks, which is not an issue for me as the gate is several yards from the house. The preservative was doing its job within 24 hours, and the weather was starting to turn colder when I applied it at about 10 deg.

Easily applied to new wood Just a slight colour change to the wood after application by P.Bougourd

Only time will tell if this product lives up to expectation but I have no reason to doubt that it will not. The reviews I read on different sites suggest that this is the best product of it's type in the market place today.

Helped restore and prolong life of damaged decking by Suzanne Allen

I bought this on the advice of someone at Wood Finishes Direct after explaining that I had inherited some rather unloved decking which had suffered damage from fallen wet leaves being left on the decking over the autumn and winter months. I applied two coats as advised in September then applied a Barretine decking oil. It certainly looks better but this winter in Buxton will be the real test. Shame it wasn't done before last winter when it snowed every month from November to April. Hopefully this will stave off complete deterioration. I've also applied it to some decking that is equally old but less damaged and it has certainly improved the appearance and hopefully the longevity.

Good stuff Thin oil mix sinks right in and easy to spray - Contain the overspray though by Matthew Lee

Only time will tell if its effective, but great absorption and residual darker shade after treatment dried shows its got right into the timber surface. Sprayed a large summerhouse with this and although it got well absorbed, the runoff during panel treatment ruined ancient cold lay tarmac which stained underlying concrete driveway 'runners' . If its oil you seek then recommended, but protect all surrounding surfaces

Great for all outdoor projects by Jordan Hulme

Have got through several cans of this for numerous garden projects that needed to be painted or creosoted. Soaks in really well, and no problems with any of the treated timber so far.

The product went on and soaked in well, it dried fast too so a second coat could be done relatively soon after the first,

Smell is not too offensive, easy to apply, and even the clear version enhances the natural texture and grain of the wood. Hopefully it will work is preserving the wood (used for a new shed).

Used on untreated timbers of log cabin by William Coates

Applied three coats on external surfaces, though with hindsight could have done this before building (did floor before assembly). Easy to apply but needs care with brush to avoid drips and splashes, and wear gloves!

Easy to apply and finished clear as described and able to follow when applying. So seems good but can't really rate a preservative after such a short period. However dispatch and delivery was excellent, less than 24 hours and the quickest I have ever had.

Very quick and easy to apply by Mr William Barker

I wanted to preserve the look of a pair of new driveway gates in pine. It was recommended that I use Barrettine Preservative followed by Osmo UV Protection Oil Extra. I applied two coats of each and am delighted with the results.
