About Concrete Resurfacing and Microtoppings
Concrete resurfacing and microtoppings restore deteriorated surfaces or change the appearance of existing concrete without complete replacement. These thin overlay systems offer cost-effective solutions for commercial properties with sound underlying concrete that has surface damage or outdated appearance.
Microtoppings are polymer-modified cement coatings applied at minimal thickness, typically 1/16 to 1/8 inch. They create new wearing surfaces that can be colored, textured, or polished. Proper surface preparation is critical for adhesion and long-term performance.
Resurfacing systems are thicker overlays, typically 1/4 to 1/2 inch, that can address more significant surface damage and provide greater wearing surface. These systems can replicate decorative finishes like stamped concrete on existing substrates.
Commercial applications include lobby renovation, retail floor updates, restaurant conversions, and any situation where existing concrete is sound but surface appearance needs improvement. These systems minimize downtime compared to complete replacement.

Frequently Asked Questions
How thin can resurfacing overlays be applied?
True microtoppings can be applied at 1/16 inch, though typical applications are 1/8 inch for better durability. Thicker resurfacing systems start at 1/4 inch. The appropriate thickness depends on existing surface conditions and finish requirements.
Will overlays crack like regular concrete?
Polymer modification reduces cracking compared to standard concrete, but overlays follow the underlying substrate. If existing concrete has active cracks, they may reflect through the overlay. We assess substrate conditions and address issues before overlay application.
How long do resurfacing systems last?
Properly applied resurfacing systems on sound concrete last 10-20 years with appropriate maintenance. Longevity depends on traffic, surface preparation quality, and maintenance. Interior applications typically outlast exterior applications.
What preparation is required for overlay application?
Surface preparation includes cleaning, profiling for mechanical bond, crack repair, and moisture testing. The preparation scope depends on existing conditions. Proper preparation is the most important factor in overlay success.
Can overlays be applied over painted or sealed concrete?
Coatings and sealers must be removed before overlay application. We mechanically remove existing coatings as part of surface preparation. Failure to remove coatings properly leads to delamination.
