Traffic Coatings

New Construction Market


Flexstone membranes are undeniably the most durable sundeck coatings on the market today. Flexstone was originally formulated for use on ski-resort decks as a membrane that could hold up to severe weather conditions and heavy foot traffic. The overall success of the coatings led to an expansion to other industrial markets like parkades and industrial flooring.

Because Flexstone was able to handle heavy foot and vehicle traffic and dramatic temperature changes we decided to pursue the sundeck coatings market. Because of the previous trials on ski resort and ship decks, we know for certain that Flexstone will last indefinitely on residential sundecks.
