Yes, you can put concrete over laminate countertops. This process is commonly known as "concrete overlay" or "concrete skim coating." It involves applying a thin layer of concrete or a concrete-like material over the existing laminate surface to give it a new, concrete-like appearance. Here's a general overview of the steps involved in overlaying concrete on laminate countertops:
Preparation: Before starting the overlay process, ensure that the laminate surface is clean, dry, and in good condition. Remove any dirt, grease, or old adhesives.
Surface Etching: To promote better adhesion, it's essential to roughen the laminate surface slightly. You can do this by sanding the laminate with medium-grit sandpaper. This step helps the concrete overlay adhere more effectively.
Priming: Applying a bonding primer to the sanded laminate surface can further improve adhesion. The primer creates a strong bond between the laminate and the concrete overlay.
Applying the Concrete Overlay: You have a few options for the concrete overlay material. Some people use a specially formulated concrete overlay mix designed for this purpose, while others use a thin layer of a cement-based product like micro-concrete or micro-topping. Follow the manufacturer's instructions for mixing and application.
Smoothing and Leveling: After applying the concrete overlay, use a trowel to spread and smooth the material evenly across the countertop surface. Ensure that the overlay is level and free of any lumps or bumps.
Adding Texture and Color (optional): If you want a specific texture or color on your concrete overlay countertops, you can achieve this by using different tools or additives during the application process. You can also stain or dye the concrete overlay after it has cured to achieve the desired color.
Sealing: Once the concrete overlay has dried and cured (follow the manufacturer's recommended curing time), apply a high-quality sealer to protect the surface from stains and moisture. Some sealers also enhance the appearance of the concrete.
It's important to note that the success of the concrete overlay largely depends on proper surface preparation and application techniques. DIY projects like this may require some skill and experience, so if you're not confident in your abilities, it's best to consult a professional who has experience with concrete overlays.
Also, keep in mind that the final result will be a concrete-like appearance rather than genuine concrete. However, concrete overlays can still offer a beautiful and cost-effective alternative to completely replacing laminate countertops.
