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 have been used, EGGER Joint & Joist Adhesive should be used to seal any fixing heads which has penetrated the surface of the board.
