• FAQ

    • What is concrete coating?

      Concrete coatings allow you to resurface an area such as a pool deck, patio, garage floor or other concrete surface without removing and replacing the concrete. It’s a beautiful alternative that saves you time, money and reduces strain on the environment.

    • What is SUNDEK?

      SUNDEK is the manufacturer of the acrylic decorative concrete coatings used by Bullion Coatings. It’s designed to beautify old or new concrete surfaces.

    • How thick is SUNDEK?

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

    • How are the coatings applied?

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

    • What does it look like?

      You get to decide! There are a variety of patterns and colors and textures including tile, masonry brick, flagstone and more. Overall, all of our concrete resurfacing projects are a semi-smooth, textured surface.

    • Are concrete coatings slippery?

      By using a semi-smooth finish you're able to safely walk on concrete coatings without the concern of it being a slick surface. Even on the shiniest finishes, we're careful to make safety first!

    • What colors are available?

      Every finish has a series of colors that you can choose from - something for everyone's taste and decor. You can even have color combinations for just the right look.

    • How long does it take to resurface my concrete?

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

    • How do you treat control or expansion joints?

      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.

    • Is the concrete surface cool to walk on?

      YES! SUNDEK is cooler than typical gray concrete, exposed aggregate, pavers, tile and even epoxy rock applications.

    • Will pool water stain my concrete coating?

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

    • Will the color fade?

      No. The SUNDEK color is an integrated color with the final three applications being an acrylic finish so it is not susceptible to fading.

    • Can you correct drainage and low spots? (bird baths)

      We will try to improve on the low spot when we are notified ahead of time. 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.

    • How do you treat cracks in concrete prior to the SUNDEK application?

      Most cracks are filled with urethane. Hairline and shrinkage cracks require no additional treatment.

    • Will the cracks reoccur?

      Answer 1) Though we do everything possible to treat concrete cracks, the truth of the matter is that 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 is just 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.

    • What if something happens to my deck after the warranty expires?

      Extended warranties are available. Please ask us for additional details.

    • Can you apply a coating over painted concrete?

      No, the concrete must be free of paint so the SUNDEK can adhere to the original concrete surface. We can help you get the concrete prepared before we apply the coating.

    • Can the concrete coating be applied to steps?

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

    • Can SUNDEK be applied to walls or other vertical surfaces?

      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.

    • Do you apply the material to cantilever faces and coping stones?

      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.

    • Can you contrast the color of the coping stones from the rest of the deck?

      Yes. SUNDEK can provide many elegant color combinations.

    • How do I clean my SUNDEK?

      There are some products made just for cleaning the SUNDEK concrete surfaces. Read more in our Maintenance section.
