BioSeal Intergrain UltraDeck is an extremely long lasting, water based oil for decking and exterior timber.

UltraDeck has been tested for use on Biowood composite timber, and has shown excellent adhesion and performance properties.

UltraDeck is the recommended coating for all GRM/Biowood exterior composite timber.

UltraDeck contains unique Hydroguard technology™ˆ which adds significant protection to guard exterior timber against Australia’s harsh natural conditions as well as the abrasive effects of foot traffic. The natural-looking finish resists stain absorption and dirt settle, helping timber stay clean.
The result is timber that stays protected and looking fresh for significantly longer than traditional decking oils. UltraDeck is available in a lightly pigmented natural colour or with mild timber tones to highlight the characteristics of popular timber species. More colour tones can be achieved by tinting UltraDeck at the paint counter.

UltraDeck is fast drying – allowing two coats to be applied in one day, and will weather naturally, without risk of cracking, blistering and peeling.
