Frequently asked questions

Common technical and specification questions for Deck.

• What is the maximum joist spacing for Plycem Deck planks?+

  Maximum 40.6 cm (16") on-center joist spacing. The 30mm (1-3/16") plank profile is engineered for this span under residential live-load conditions. For commercial applications with higher pedestrian loads, the design engineer should confirm joist spacing and connection details.

• Can the planks be painted, stained, or dyed?+

  Yes — the surface accepts paint, stain, and integral dye. Many specifiers prefer dyeing for a wood-tone finish that won't chip or peel. Use exterior-grade coatings rated for cementitious substrates; manufacturer technical bulletins list approved coating systems.

• How does the clip-based installation system work?+

  Planks are fastened to joists using hidden stainless-steel clips that engage grooves in the plank edges, leaving no exposed fasteners on the walking surface. This delivers a clean monolithic deck appearance and accommodates seasonal expansion/contraction without surface cracking. Clips are sold separately by the same manufacturer.

• How does fiber-cement deck compare to wood or composite for moisture resistance?+

  Fiber-cement is dimensionally stable in wet conditions and will not rot, warp, or harbor mold like wood, and will not soften under prolonged UV exposure like some wood-plastic composites. Density is 1.0–1.3 kg/dm³ and flexural strength is 10 N/mm² minimum — superior to most wood-composite decking products.
