Applying Cuprinol Wood Preserver Clear: We recommend applying two coats along the wood grain using a brush to clean, dry surfaces before painting or varnishing. Before application, remove excessive dirt and soiling, large areas of algae, lichen or fungi using an appropriate fungicidal wash or cleaner designed for the job. Wood that has been wood-stained, painted or vanished should be stripped back to bare wood and treated as bare wood. Leave the first coat to soak in before applying the second but reapply before the first is fully dry (typically 2-6 hours). Leave 16 hours for the second coat to dry before painting, staining or varnishing. Do not spray. A colourless general-purpose preserver for interior or exterior use. It gives deep penetrating protection to sound wood against decay, mould and blue-staining fungi. It has also been developed with a low odour formula to make it more pleasant and convenient to use. Actively prevents rot and decay. Colourless preserver for both interior and exterior use. For use as a basecoat before painting, staining or varnishing.
