How to prepare wood for the best finish

Remove dust and loose fragments with a natural bristle, or stiff nylon, brush, then sand to a smooth surface removing any weathered wood. Dust with a clean dry brush, and then wipe clean with a damp cloth, ideally use Methylated spirits. Leave to dry before applying your coating. Never use White Spirit or wire wool / brushes on wood. White spirit leaves a greasy residue, while unsightly marks and rust can result from metallic fragments.

How to ensure colour consistency

If you’re using more than one batch of woodstain in the same area, mix together in a large container to ensure you get consistency of colour. Translucent woodstains will vary in appearance depending on the natural colour or density of the wood. For example the same stain applied to softwood will look lighter in comparison to application on a hardwood. Application of additional coats will also deepen the final colour of a woodstain, so for all these reasons a trial application is recommended to ensure you get the result you desire.

How to prepare decking for decoration

    • Decking should be inspected annually and treated as necessary.
    • Brush the surface with a stiff broom to remove dirt and debris.
    • Remove algal or mould growth with a fungicidal wash, then rinse with clean water.
    • Remove any flaking coating and grey weathered timber by mechanical sanding.
    • Clean the timber by wiping with a cloth dampened with methylated spirits or cellulose thinners (never use white spirit as this add grease to the surface).
    • Allow the decking to dry completely.

    We recommend coatings from our sister brand, Sadolin, to finish the task.  Pay particular attention to the end of your decking  as they are 100% more absorbent than the face grain.

    Sadolin Superior Wood Protection , with Sandtex Exterior Paints, is part of the Crown Paints Family of products.  We recommend the following coatings for decking:

When to apply wood treatments

We recommend that all of our woodcare products are not applied, or allowed to dry, in temperatures below 8 degrees centigrade, or above 25 degrees. It is also important to consider that relative humidity levels should be below 80% during drying times.
Using products recommended to exterior use indoors will result in extended drying times.

What brush should I use?

Quality natural bristle brushes are best for solvent based systems, whereas we recommend synthetic brushes for water based.

Applying your wood care product

When coating, consider all exposed surfaces and those that are susceptible to unwanted moisture ingress. End grains are particularly vulnerable, for example on decking and garden architecture such as pergolas. Window sills should be rounded off to avoid sharp edges where it may be difficult to achieve an adequate film build up. Finally, ensure sufficient product is applied. Window rebates and glazing beads should be fully coated before fitting.
