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.

    Spoke to Palatine Paints before ordering and they were easy to get hold of. The person I spoke to was able to answer my questions quickly and with confidence. The product arrived quickly and in good condition. Also, they are the best value option from seven different firms that I contacted.
