Terraprotect: deck joint tape

Terraprotect prevents large debris and superficial dirt such as leaves or pine needles from getting below the decking.

The UV-resistant joint tape is suitable for a joint width from 6 mm to 7.5 mm. Application is only possible for patio decking that has been laid with WPC or thermally treated boards. The laid boards should not display any swelling or shrinkage. It should also be ensured that the decking has sufficient underside ventilation (min. 8 cm).
