Frequently Asked Questions


  • What is Flexstone?

    Flexstone is a line of premium urethane coatings. The system is comprised of both a thick urethane base coat and a UV stable topcoat system. There are two different systems for the protective top layer. The standard colour coat is a thick, flexible, and durable urethane deck paint (applied over base coat). The standard colour coat is available in 4 colours. The second finish type is a textured stone finish which imitates textured stone but retains its flexibility. The appearance is achieved by applying a thin layer of urethane top-coat, broadcasting a blend of fire-resistant acrylic chips, and finishing with a clear urethane topcoat. See how the system is composed below.

  • How long will my Flexstone surface last?

    Flexstone on a residential sundeck will last indefinitely, but 20-30 years can be achieved easily. On industrial or vehicular applications, the membrane may begin to wear down after heavy traffic, but even then you will get at least 10 – 15 years out of the membrane before any repairs or re-top coating is required. The longevity of our product is why it is so easy for us to warranty.

  • What types of surfaces can Flexstone be applied to?

    The Flexstone base coat can be applied over almost any surface and maintains a tremendous bond with the substrate for decades. These surfaces include new plywood, concrete, torch-on roofing, metal, and fiberglass. 
    At Pro Surfaces we do not recommend applying Flexstone to newer treated wood as we have found it can bubble.

  • How is Flexstone in the winter?

    Flexstone performs great in the winter! You can shovel it, use the snow blower on it & de-ice it all you want, but we don't recommend using an ice pick on it. 

  • Is Flexstone slippery?

    Both the textured stone finish and standard colour coat finish have a good amount of traction. 
    We add a silica sand into the top coat. Applicators can simply add more or less to get the amount of traction that makes sense for your job. The textured stone finish is made up of acrylic chips broadcasted into the surface. These are sanded before applying a clear coat. The amount of sanding dictates the coarseness of your surface so homeowners can get the right amount of grit for their needs. 
    If you want to be sure that your surface is extra textured, let your sales representative know so that they can make a note for the installation team. You can also confirm this with the Project Manager.

  • What is the warranty for Flexstone?

    Flexstone products are warranty varies from 10-20 years depending on traffic / abuse / applications etc. Most Flexstone dealers will offer an extended warranty that covers any problems with workmanship, but regardless, we have your back and are proud to stand by our amazing coatings.

  • Is Flexstone Eco-Friendly?

    Flexstone is entirely eco-friendly for a variety of different reasons. 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, urethane, or fiberglass 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 retain building heat in during the colder months.

  • What types of approvals does Flexstone have?

    Flexstone is fully approved by CCMC (Canadian Construction Materials Center) for use on flat roofs. Because there is no designation for sundeck approvals in Canada, Flexstone was exposed to the harsh testing associated with flat roof membranes. The product passed with flying colours and is now eligible for any waterproofing application over living space. The product also has the equivalent of these approvals in California, US.

  • If I manage to damage my Flexstone surface, can it be repaired?

    Unlike vinyl decking or epoxy finishes, repairs to Flexstone are incredibly simple. Say for example, you drop a red-hot charcoal briquette on your Flexstone deck, and the coal burns an unsightly scar into it. The area can simply be sanded, wiped down with a solvent, and then flexstone can be re-applied. 
    Lets take a look at a more extreme example. Say you are doing a little carpentry and you accidentally saw through your membrane to the plywood or concrete below. We can simply take a very small amount of base coat, fill the crack or gouge, and then re apply the chips and finish coat. 
    One thing to note, your top coat will look shinier than the rest of your deck for about a year until it blends in.

  • Can I change the color of my Flexstone Surface?

    Fortunately, Flexstone simply does not wear out for decades, so it does not need to be torn off and re-coated when a client decides to change colours. Say you had a sidewalk grey sundeck done on your home. Several years later you have your house painted brown and want to update your deck colour to the brown textured stone finish. We simply roll out a top coat, broadcast our chips into it, and top off with a clear coat. The base coat stays put and your costs are minimal.

  • How does Flexstone's compare to Epoxy for garage floors?


  • How does Flexstone compare to Vinyl products like DuraDeck? 



  • Where can TeraFuse be used?

    On any concrete surface that needs resurfacing. We can either patch specific areas or resurface the entire area.
    It is commonly used to patch stairs, driveways, and garage floors.

  • How well does it bond to concrete?

    TeraFuse bonds extremely well to concrete, but concrete is porous. Just like traditional overlays, water will eventually seep between the original concrete and the overlay, causing a separation. When used in combination with Flexstone, our waterproof coating system, it can last indefinitely (at least 20 years).
