Stamped Overlays
Stamped overlays involve applying a textured pattern to the concrete overlay, creating a decorative finish. This method is suitable for patios, walkways, and driveways.
Micro-Topping
Micro-topping involves applying a thin layer of cement-based material to the existing surface. This method is ideal for interior floors and countertops.
Protecting Old Concrete
Once the concrete surface is restored, it’s essential to protect it from future damage. Here are some common protection methods:
Sealing
Sealing involves applying a concrete sealer to the surface to protect it from water, stains, and chemicals. There are two main types of sealers: topical and penetrating.
Coatings
Coatings involve applying a thin layer of material to the concrete surface to protect it from wear and tear. Common coatings include epoxy, polyurethane, and acrylic.
Additional Tips and Considerations
When making old concrete look new, it’s essential to keep the following tips and considerations in mind:
Assess the Condition of the Concrete
Before starting the restoration process, assess the condition of the concrete to determine the best course of action.
Choose the Right Materials
