What is the difference between Barrettine Wood Preserver, Wood Protective Treatment and Universal Preserver?

Barrettine Wood Preserver

• Our premium product, providing complete protection.
• No topcoat required.
• Contains biocides that protect against wet rot, decay and wood-boring insects.
• Contains a high level of resins, which repel water and physically protect the wood
• Available in clear and a range of colours.
• Complete treatment, ideal to protect bare untreated wood
• Suitable to treat wood that has been exposed for a long period, requiring further protection.
• Please refer to the product label for the full guidance and usage conditions

Barrettine Wood Protective Treatment

• Provides non-biocidal protection, nourishing the wood and repelling water ingress that can cause decay. Less protection is given than Barrettine Wood Preserver
• Ideal for use on pre-treated timber
• Contains a surface biocide to protect against the growth of surface mould
• Contains quality resins, which repel water and physically protect the wood
• Available in clear and a range of colours
• Suggested for use on pre-preserved wood, e.g. pressure treated/tanalised timber
• Please refer to the product label for full guidance and usage conditions.

Barrettine Universal Preserver

• Primer, requiring over-coating if weathering expected
• Can be used on structural timbers such as roof/floor joists without a topcoat
• Contains biocides that protect against wet rot, decay and wood boring insects
• Resins & binders present are intended to retain the biocides rather than repel water
• Available in clear only
• For use on bare wood which will be over-coated, for example with Barrettine Log Cabin Treatment or opaque paint, or physically protected from the elements.
• Compatible with many products both water- and solvent-based. Compatibility with any additional coating should always be confirmed by a test patch.

It should be noted that the above products are preventative treatments and these products are unlikely to kill/control mould spores already present within the wood. If this is suspected, Barrettine Mould and Mildew Cleaner should be used, prior to coating the wood. The bottom of wooden structures e.g. sheds will also require more frequent treatment with Mould and Mildew Cleaner, as the action of rain splashing on the ground will distribute mould spores onto the wood. Frequent treatment with Mould and Mildew Cleaner can prolong the life of the wood coating. Also, repeat and periodic re-treatments using the above wood care products will enhance and protect the appearance, and prolong the life of the wood.

Additionally, whilst Barrettine Wood Preserver and Universal Preserver are protective against wood-boring insects, they will not kill existing infestations. For this, Barrettine Woodworm Killer would be required.
