When using EGGER Protect in applications where the boards will be exposed to the outdoor elements during construction, EGGER recommends that any exposed edges are sealed using EGGER Joint & Joist Adhesive to prevent moisture ingress which can lead to unwanted swelling of the board.
Additionally, where any mechanical fixings (screws or nails) are used, EGGER Joint & Joist Adhesive should be used to seal the hole where the fixing penetrates the surface of the board. For further information please refer to the EGGER Advanced Structural Flooring System.
