Working with TimberTech 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 TimberTech 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.
