Traffic and Deck Coatings

By orderA traffic system is bought by the deck, not by the pail — the coverage rate, the number of coats, and the aggregate all come off the spec. So it is ordered against your deck, with the lead time quoted before you commit. Send the square footage and the system.

A plaza deck with topping and pavers over it is not a traffic coating job — it is a hot-applied membrane job, and that is TREMproof 6100, which is on the floor. The dividing line is whether tires and boots touch the coating or touch something laid on top of it. See below-grade waterproofing.

Vehicular systems are thicker, tougher, and cost more, because a tyre turning in place does more damage to a coating than a thousand people walking. Balconies and plaza decks take pedestrian; parking decks and drive lanes take vehicular; the turning areas and ramps in a parking structure often take a heavier build than the flat runs. The spec will say, and the difference matters.

A Colorado parking deck goes through a hundred freeze-thaw cycles a winter and gets salt dragged onto it every day. That is the environment these systems exist for — and it is why a deck coating that gets skipped or thinned shows up as spalled concrete and rusted rebar in five years rather than fifteen.
