FAQ’s – Frequently Asked Questions

    SUNDEK is an Acrylic Decorative Concrete Coating designed to beautify old or new concrete surfaces.

    SUNDEK is about as thick as 2 quarters stacked on top of each other. (Just under a quarter-inch) However, SUNDEK can be used as a blending tool to feather uneven surfaces up to 2 inches deep.

    SUNDEK is a multi-layered product that is applied by factory trained professionals. Depending on the surface conditions and patterns chosen, there will be 4 to 8 layers of material applied to the deck surface.

    SUNDEK is a semi-smooth, textured surface that can have the appearance of classic texture, tile, and brick patterns to name just a few. Please see our photos section to see hundreds of pictures so you can get an idea of our limitless design options.

    We have 16 Signature Colors, 24 SunDye Colors, and 9 SunAcid Colors to choose from. We also have a limitless array of Custom Colors that can match any surface around your home.

    Depending on size, condition, and weather, a typical installation takes approximately 2 to 8 clear dry days.

    We maintain all existing control joints, to allow for expansion and contraction of the concrete. We do, however, apply the SUNDEK finish coat to expansion joints to match the deck color, and we also replace worn out expansion joints.

    SUNDEK is much cooler than typical gray concrete, exposed aggregate, pavers, tile and even epoxy rock applications. Learn more about cool coatings for Decks for around pools.

    No, Kool Deck is a product designed to form a mechanical bond on freshly poured concrete. (Within the first 5 hours.) SUNDEK is formulated with a chemical bond; therefore, SUNDEK can be applied to new or old concrete.

    No. The standard SUNDEK classic texture and masonry effects have 2 layers of an acrylic finish coat. These acrylic finishes provide a durable non-porous surface which make it stain resistant and easy to maintain.

    We will try to improve on the low spot when we are notified ahead of time, however, we will attempt to change the pitch to move the low spot somewhere else or make it twice as wide and half as deep so the sun will dry it up quicker. Because the SUNDEK Finish Coat is non-porous your surface will not soak up water like concrete.

    Most cracks are filled with urethane. Hairline and shrinkage cracks require no additional treatment. (Please refer to your local SUNDEK contractor for specific details for crack repair.)

    Answer 1) Though we do everything possible to treat concrete cracks, the truth of the matter is, they may recur. If they do, it is usually always in the form of a hairline crack which is not objectionable as it is largely hidden in the texture. However, if a crack becomes bothersome to you, we will be happy to repair the crack for you for a nominal service charge. Answer 2) If the above answer doesn't do the trick, our “Custom Scoreline Effect" design may be right for you! We take all your existing cracks and grind them open, separating the product where the concrete is cracked. (Just as we do with expansion joints.) Then, before applying the Finish Coat we will grind additional lines into the texture to create a pleasing design and keep your deck from cracking.

    No, the concrete must be free of paint so the SUNDEK can adhere to the original concrete surface.

    YES. SUNDEK can be applied to concrete steps including risers and treads.

    YES. SUNDEK can be applied to vertical surfaces. From the properly sealed backyard retaining wall to the multi-storied building, SUNDEK can be applied on exterior and interior walls.

    Yes we do apply SUNDEK to cantilever faces and coping stones. Even though the application over coping stones is a matter of personal preference, it is often advisable to SUNDEK them unless they are exceptionally new. (The stones are porous like concrete). If not surfaced, the coping will tend to look old and dirty after the SUNDEK installation is complete. In addition, you can add our Masonry Brick patterns to copings and cantilevers at a fraction of the cost of real pavers.

    Yes. SUNDEK can provide many elegant color combinations.
