Preparation

Preparation

Back

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 Barrettine End Grain Preserver

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

Application

Back

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°C. Wood should be frost-free when treated. Shake well prior to use.

  1. Apply Universal Preservative 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

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.

F.A.Q.

F.A.Q.

Will the Barrettine Universal Preserver give me UV protection?

No, this product does not contain UV filters. If UV protection is required to delay the greying effect that the sun causes, then consider a UV Wood Oil or Wood Varnish over the top.


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.


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.


Is this suitable for waterproofing an untreated external pine door?

This product is not designed to be used as a topcoat as it is a preservative that contains no wax. It needs to be sealed with a suitable coating such as a Wood Oil, Wood Stain or Paint for Wood

Good stuff
Easy to use. Have used before so know it works. Used on exterior timber repairs to a window frame and followed instructions re drying time before painting and had no problems. Whether it works in the long term, well not had problems before with any wood preserver but I haven't lived long enough for the wood that I have treated to rot (or not).

Does the job, easy to apply
Only criticism would be that the coverage rates given on the website and on the tin seem to be overestimated so ended up buying more than required.
