VERY IMPORTANT for all uses of Finex panels

  • Only install perfectly dry panels (let pallets dry for 72 hours, individual panels for 24 hours).

  • Leave an expansion joint of at least 1/8’’ between panels. If a flexible adhesive sealant is used on a 4' x 8' panel installation, leave a minimum space of 1/2" (12 mm) along the width of the panels and 1/4" (6 mm) along the length. A polyurethane base sealant is recommended such as : Sika Flex Construction Sealant.

  • Please note: The installation of Finex panels with adhesive sealant or finishing products should not be considered as a waterproofing system. Is such a system is required, put it in place before you install the Finex panels or after with a fluid-applied waterproofing system, refer to the waterproofing system manufacturer installation guide.

  • Pre-drill screw holes 1/16’’ wider than the screw diameter.

General Handling Guidelines

  • Carry panels on their side, not flat.
  • Corners and edges are fragile before installation.
  • Store panels flat, inside or with adequate protection.
