Why we love it
  • Enhances natural wood features.
  • Secures outdoor timber durability.
  • User-friendly application process.
Main Highlights
  • REBRANDED - Our rebranded original treatment 'Solvent Based Protection is now called 'Wood Protector'. The same great product and formula, just with new and improved branding.
  • NATURAL OAK WOOD PROTECTOR - Our Oak Wood Protector has a semi-translucent finish that doesn't mask the wood grain. Our Oak Wood Protector is designed to enhance and protect the natural look of wood.
  • EXTERIOR WOOD PROTECTION - Our Oak Wood Protector can be used on most outdoor timber and is recommended for use of sheds, fences and general garden furniture. This wood protector creates a water-repellent barrier, and a high UV-resistant finish and prevents dry-film fungal growth - perfect for all outdoor wood!
  • EASY TO APPLY - Our Oak Wood Protector can be brushed, sprayed or dipped depending on your requirements. This wood protector provides an even application with excellent coverage that dries quickly.
  • OUR RECOMMENDATION - The wood protector, when applied to rough sawn wood may appear a lot darker than if the same product was used on smooth planed wood. We strongly recommend that you apply Timbashield to a small inconspicuous area (and allow it to dry) prior to extensive use. Different types of wood will also affect the final shade and depth of colour.
