Exterior 450 Gloss - 3.785 litre

Exterior 450 Gloss - 3.785 litre

Exterior 450 provides a clear drying tough, protective finish that will withstand the rigours of the sun, rain, and wind.  It is suitable for vertical surfaces such as fences, patio furniture, garage doors, entrance doors, outdoor kitchens and interior windows. It is not recommended as a deck finish. Fortified with UV absorbers to stabilise the finish, Exterior 450's built-in mildewcide retards mould and mildew growth. Tough and flexible, it will resist the expansion and contraction of the wood through hot summers and cold winter. Exterior 450 performs well as a clear coat or as an optional topcoat over General Finishes Milk Paint. It can also be used as a tint base to create custom colours. Warning: We do not recommend Exterior 450 stains or topcoats for exotic woods Ipe, Teak, or other dense oily woods that will get exposure.

Furniture Care and Maintenance


Cure First
You have just finished applying a fine furniture finish. Treat gently until the paint or topcoat have fully cured. Allow 21 days for a water-based finish to cure before cleaning.


Regular Cleaning and Maintenance

  • Remove dust with a water-dampened cloth. Dust can build up over time and may scratch or dull finishes if not removed regularly. 
  • Remove fingerprints, cooking fumes and smoking residue with mild soap and water. These contaminants will not harm the finish, but they accumulate on surfaces and dull the original lustre. 
  • As with all fine furniture finishes, avoid using furniture polish, cleaners or dusting sprays that contain silicone, alcohol, ammonia and anything acidic. Exception: We have successfully cleaned with Clorox wipes.
  • Clean up water, alcohol and food spills in a timely manner and use placemats & coasters to protect the finish.
  • Future finishes or touch-ups may not adhere properly or perform as desired over a contaminated surface. Some contaminants, such as silicone, seep through finish into the wood and often cannot be removed.
  • Avoid excessive exposure to direct sunlight, high temperatures or high humidity. These can damage furniture and finishes.
