Protek Wood Preserver is a water-borne product based on modified vegetable oil. It contains active ingredients effective against wood destroying and wood discolouring fungi.



Stain Blocking Primer

Protek Stain Blocking Primer is effective at blocking tannins and pressure treatment chemicals.

We would recommend using this primer when white or light colours are used as a topcoat to stop any unsightly yellow staining coming through from the wood. This is not usually an issue with natural wood colours so it is not necessary to use this primer with them.

For use on all outside wood that is not in direct contact to soil or surface water.
