Unrivalled versatility & durability

Flexstone is an attractive and versatile industrial-strength waterproofing membrane. It is designed to easily withstand heavy abuse from the elements and 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 it’s 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. The base coat is installed thick with a v-notched trowel or squeegee.

The finish coats are not only aesthetically gorgeous, they 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 Flexstones is Better


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


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


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


Unlike other membranes, if you damage your Flexstone Deck it is an easy fix. Simply sand, wipe and reapply the coating!


Every component of the Flexstone system is designed to flex together. So the inevitable movement and shifts of your sundeck will not lead to cracking and 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% solvent-free (water catalyzed). This property allows it to be applied over existing coatings, other urethanes can not do this because the solvents will dissolve the membrane below. This feature allows building and homeowners to apply the product over old vinyl, fiberglass, or torch-on membranes; keeping roof and deck debris out of our landfills. Secondly, the UV stability and reflective nature of the finish coats save on building energy costs. This means that air conditioning units run for a fraction of the time during warmer months and the seamless insulation properties of the product hold heat in during the colder months.
