Barrettine Cladding Preserver

Barrettine Cladding Preserver is a solvent-based wood preservative specially designed for use on all softwood and hardwood, untreated cladding timbers. The deep penetrating formula protects against fungal decay such as wet rot, wood discolouring fungus and wood boring insect attack. Provides a clear finish and contains resins and oils for water repellency and protection against weathering.

It can also be used on external walls such as doors, windows and their frames (inner & outer surfaces), facades, carports, shutters, summer houses, gates and balcony railings. Also for use where wood is resting on the ground / hard standing and only submitted to intermittent wetting, such as rain, on projects such as garden furniture.

Please note: it is not suitable to treat wood for any in-ground use or where the wood is permanently subjected to continual wetting such as joinery in streams and ponds.

Ensure that wooden surfaces to be treated with Barrettine Cladding Preserver are clean, dry and free from surface dirt, debris and other surface contaminates.

New Bare Wood

1. If required, new bare timber can be cleaned and de-greased with methylated spirit prior to application of wood preserver
2. Freshly cut sawn ends should be thoroughly treated with either Barrettine Cladding Preserver, or alternatively Barrettine End Grain Preserver

Previously Treated Wood

1. Any surface coatings such as paints, varnishes and stains must be fully removed back to clean, bare wood by sanding or using a suitable stripper / remover
2. 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

1. Wood that has become decayed should be removed and replaced
2. Cut out and burn all decayed wood at least 45cm beyond the area of damage
3. Brush down the wood with a stiff broom or brush to remove any ingrained surface dirt and debris
4. Traces of mould, algae or fungi must be removed with a stiff brush or scraper
5. Areas that have been affected by mould, algae or fungi should be treated with Barrettine Mould and Mildew Cleaner
6. Any existing cases of woodworm can be treated with Barrettine Premier Woodworm Killer
7. Fill any gaps or splits in the wood with a suitable wood filler

All sides and edges of the cladding should be treated before fixing with at least 2 coats to ensure adequate absorption into the fibres of the wood.

1. Shake the tin well to ensure contents are mixed thoroughly
2. Apply using a bristle brush, spreading out thinly and evenly, ensuring end grain is thoroughly treated along with cut and drilled areas
3. Reseal container after each use
4. It is recommended that a minimum of 2 coats are applied depending on wood species and surface characteristics.
5. Allow 6-12 hours drying time (touch dry) between coats. Application of successive coats will provide a darker finish and on smooth wood a higher sheen finish
6. If using the in conjunction with a stain / wood dye it is recommended to apply the colourant before the Preserver, test areas should be carried out before starting the main job

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