Installation Guidelines STOP! Read this section before you start! (continued) Always make sure to visit www.azek.com to ensure you are viewing the most current installation instructions, care and cleaning, technical information and more. DO NOT attach deck boards to a floating sub-structure which is not mechanically fastened frequently and sufficiently to the building and roof deck.
Working with AZEK® Deck Boards Excessive Construction Debris It is important during construction, the deck’s surface stay clear from excessive build-up of dirt, sand, and dust from tile, concrete, landscape blocks, or any other masonry products. If these materials are not removed immediately, the deck surface will become difficult to clean and can potentially damage the deck’s surface finish. Do not use AZEK Deck as a work surface.
Working with AZEK® Deck Boards Expansion and Contraction AZEK Deck/Rim Joist Covers will have expansion and contraction with changes in temperature, unlike wood whose size will fluctuate with moisture changes. The expansion and contraction encountered may result in slight gaps, which might be noticed at the ends of boards or in splice joints. Fastening the deck boards according to the Installation Guidelines will help minimize expansion and contraction.
Working with AZEK® Deck Boards • AZEK TopLoc color match stainless steel deck screws are also available. Your AZEK Building Products dealer can assist with more information on these products. • AZEK does not recommend any fastener that is not explicitly stated in the AZEK Decking and Installation Guide. Use of any alternative fastener does not void the AZEK warranty; however, if a decking failure is caused by using one of these alternative fastening methods, any corresponding claims will be denied.
