Extend the life of your deck

NewTechWood composite decking boards have a 25-year limited warranty. However, the substructure of your deck (i.e. the joists and beams supporting your deck) may start to split and rot after around 10 years – unless it is effectively maintained and protected.

Joist tape provides a low-cost, effective way of preserving the joists and beams, thereby extending the life of your deck’s substructure.

NewTechWood deck joist flashing tape is a self-adhesive, waterproof tape. Specifically designed to shield the joists, beams and cut ends from moisture, it prevents decay and wood-rot.

By creating a seal around the deck’s screw-holes, the tape restricts moisture penetration and also prevents the screws from loosening.

Made of a rubberized asphalt mastic adhesive, this non-skid, anti-stain tape is UV-protected and will withstand the harsh Australian conditions. It can be applied in any temperature, summer or winter. Unlike protective paint, joist tape is super-easy to use, does not create mess and saves you time.

NewTechWood’s simple peel-and-stick joist tape is so easy to install, it’s almost child’s play, but we do have a simple 2-page visual installation guide to assist.

Each roll of NewTechWood joist tape is:  5cm x 1524 cm.
