You are not able to use Oil Wax Finish on those tiles as oil wax is meant to be used directly on raw wood. For the bitumen roof tiles, you may use AFM Safecoat Roofguard. For the cellulose ceiling tiles, you may first coat with AFM Safecoat Transitional Primer and top coat with the AFM Safecoat Zero VOC Paint.
