Unrivalled versatility and durability

Flexstone is an attractive and versatile industrial-strength waterproofing membrane applied in layers. It is designed to easily withstand the elements, as well as heavy foot or vehicular traffic. Flexstone is the common-sense answer for sundecks in Canada.

Flexstone’s four-ply CCMC-approved rubberized membrane relies on the foundation of its solvent-free base coat, which adheres to nearly any substrate (concrete, plywood, fiberglass, vinyl, urethane membranes, torch-on, and more) and retains its flexibility indefinitely. This base coat is installed in a thick layer with a v-notched trowel or squeegee.

The finish coats are not only aesthetically gorgeous, but they also have an important job. Our rugged mock-aggregate finishes provide a tough but flexible outer shell that keeps the membrane safe from heavy traffic and UV damage.

Why Flexstone is Better


Flexstone offers a variety of luxurious finish options designed to suit nearly any home design scheme.


Flexstone is formulated to handle dramatic temperature fluctuations, vehicle traffic, and foot traffic, making it an ideal deck coating.


Flexstone on a residential sundeck can last almost indefinitely—easily 20–30 years before repairs or top-coating is needed.


Unlike many other membranes, damage to your Flexstone deck is easily fixed: simply sand, wipe, and reapply the coating.


Every component of the Flexstone system is designed to flex together. The inevitable movement and shifts of your sundeck will not lead to cracking or leaks.


Flexstone is an approved flat-roof membrane that has passed all the rigorous requirements put in place by the federal government.

Flexstone is eco-friendly

First, the base coat is 100-per cent solvent-free (water-catalyzed). This feature allows application right over old vinyl, fiberglass, or torch-on membranes, keeping roof and deck debris out of our landfills. Other urethanes cannot do this, because their solvents will dissolve the membrane below. Secondly, the UV stability and reflectivity of the finish coats save on building energy costs—air-conditioning units run for a fraction of the time during warmer months, and the seamless windproof membrane holds heat in during the colder months.
