Blackfriar Exterior Wood Protector Gold Star 5L is designed for easy and effective treatment of exterior timber, whether you’re working on new wood or refreshing older surfaces. Follow these steps for the best protection and finish:

Surface Preparation

Ensure all timber surfaces are clean, dry, and free from dirt, grease, algae, mould, and loose material.
Remove old flaking coatings or paint with a scraper or sander. For previously treated wood, lightly sand to improve adhesion.
Treat any existing fungal or algal growth with a suitable fungicidal wash and allow to dry fully before application.

Application Guidelines

Stir thoroughly before and during use to maintain colour consistency.
Apply evenly by brush or roller, working along the grain of the timber for best penetration.
For new or highly absorbent timber, apply two coats, allowing the first to penetrate before applying the second.
Avoid application in damp conditions or if rain is expected within 24 hours.
For decking or horizontal surfaces, apply extra coats for maximum durability and allow adequate drying between coats.

Drying & Maintenance

Touch dry in approximately 4–6 hours depending on weather conditions; recoat after 16–24 hours if needed.
Provides up to 3 years of protection on vertical timber and up to 18 months on horizontal surfaces.
Inspect surfaces annually and reapply as required to maintain optimum protection and colour richness.

Best Practice Tips

Always test the colour on a small, inconspicuous area before full application, as final shade may vary with wood type and porosity.
Regularly stir the product during use to avoid colour settling.
Clean tools immediately after use with white spirit.
