Frequently Asked Questions

Is the finished surface slippery to walk on?

This is something everyone is concerned about, especially around a pool or on a driveway. Our unique process of hand troweling the texture, creates a profile that is slip resistant. As a secondary precaution, we add a polymerized non-skid additive to the final coat of sealer.

What do you do about cracks in the existing concrete?

Crack are always an issue with any overlay. Urethane caulking and rigid epoxies are widely used by coating companies, but the cracks usually come back. We have two options. If the finish being applied is a random flagstone pattern, we incorporate the existing cracks into the grout lines. That way if they do come back, they are hidden in the grout joint and not running through the stones. If the pattern is to be a square stone or seamless finish, we us a concrete staple system that will actually restore the multi-directional strength of the concrete and prevent the cracks from reappearing. If necessary, new expansion joints can be added to areas that are too expansive.

Can you coat over the expansion joints?

No. Expansion joints are necessary to control the expansion and contraction of the individual concrete pads and prevent cracking. Anything placed in the expansion joints that is not pliable, will crack and fall out, causing damage to the overlay as well. We replace the existing joint material, whether it’s wood or plastic, with a pour-able polyurethane joint mastic. The mastic is then sprinkled with sand before it cures, to give it a more natural look.

I’ve heard that some concrete overlays are twice as strong as concrete. Is that true?

Technically, no. While the compressive strength of overlays is generally higher than 3000 psi. concrete, the test methods for overlays and concrete slabs are different. Overlays are made to be installed in thin sections and are tested as such. If the overlay product was tested using the same test for concrete slabs, it would have a much lower rating than concrete. Same goes for concrete tested using the overlay test method. While overlays do have a high compressive strength rating and will withstand a very high amount of downward force, they will not add any structural strength to the substrate they are applied to. Just as important as compressive strength, is the adhesion, tensile, and flexural strength. For more info about the characteristics of overlays, please see our articles page.

​What surfaces can StoneKrete be applied over?

StoneKrete was formulated to bond to most structurally sound building materials. Exterior; concrete, pea gravel, natural stone, tile, and brick – driveways, pool decks, patios, walkways, and walls. We even have a system that will allow StoneKrete to be applied to wood decks and balconies. Interior; floors, walls, fireplaces, and shower surrounds.

How often do I need to reseal the surface?

We recommend that you reseal your exterior StoneKrete surface every 2 to 3 years depending on the amount of use it gets and it’s exposure to the elements. For example, a driveway would probably need to be resealed before a covered patio. Your StoneKrete overlay was installed with 2 coats of solvent based, acrylic sealer. As the sealer wears, the surface will just be more susceptible to staining and color fade, but does not affect the structural integrity of the coating.

What is the warranty for the installed StoneKrete overlay?

We offer a limited 3 year warranty on the installed StoneKrete product, that covers delamination from the substrate that it was applied to. The warranty may be extended for another 3 years, if it is cleaned and re-sealed within the initial 3 year warranty period. As the manufacturer and installer, we have full control of how the products are being made, therefore we are confident enough in our products ability to offer this warranty. Please ask to see a copy of our warranty for all terms and conditions.
