Even the best concrete has its imperfections in the form of cracks, discoloration, holes, and other flaws. While repairing concrete can help fix some of these flaws, the repairs themselves can be noticeable and unattractive. When concrete overlays are installed they provide a more consistent concrete floor look.
Types of concrete overlays
| Concrete Refinishing System | Application Thickness | Performance Attributes |
|---|---|---|
| Microtoppings or skim coats | Featheredge to 1/8 inch | These polymer-based systems are applied super-thin, giving them the ability to flex, unlike other systems. May also be applied to wall surfaces. |
| Spray-down systems | 1/8 inch | The textured finish is durable and skid-resistant, making it well suited for surfaces such as pool decks, sidewalks, and driveways. |
| Stampable overlays | 1/4 to 3/4 inch | Are applied thickly enough to accept texture and cover minor imperfections in the concrete substrate. |
| Self-leveling overlays | 1/4 to 1 inch (in one lift) | Restores structurally sound yet worn concrete surfaces and can be used to level uneven floors. |
| Underlayment’s | Up to 1 1/2 inch | Restores structurally sound yet worn concrete in preparation for floor coverings. Provides a smooth, flat base. |
