How to Laminate Over Laminate on a Cupboard: A Comprehensive Guide

Renovating your kitchen cupboard can be a relatively straightforward process when you apply laminate over existing laminate. This method can save you both time and money without compromising the overall aesthetic appeal of your kitchen. By following these detailed steps, you can achieve a professional-looking result that freshens up your existing cupboard.

Surface Preparation

The key to a successful laminate over laminate application lies in thorough surface preparation. Begin by cleaning the existing laminate panels to remove all grease, dirt, and residue. Use a mild detergent and water, or a solvent such as acetone for stubborn dirt. Ensure the surface is clean and dry before moving on to the next step. This step is crucial as it ensures the adhesion of the new laminate to the existing surface.

Sanding (for original laminate)

For applications where you are adding a new laminate sheet over the existing one, sanding is necessary. Use fine-grit sandpaper, approximately 220 grit, to lightly sand the surface of the old laminate. This creates a rough texture, enhancing the adhesion between the old and new laminate. For post-forming laminate, skip this step and go straight to the application process.

Adhesive Selection and Application

Choose a suitable adhesive for laminate application. Contact cement is commonly used and should be compatible with both the existing and new laminate materials. Follow the manufacturer’s instructions carefully when applying the adhesive. These instructions usually involve applying it to one surface, allowing it to become tacky, and then pressing the surfaces together firmly. For laminate over laminate, this step is particularly important to ensure a strong bond.

Cutting the New Laminate Sheets

Measure and cut the new laminate sheets to the appropriate size. It's a good idea to allow for a small overhang, which you can trim after installation. This ensures that the sheet fits perfectly, and any excess can be neatly trimmed for a clean finish.

Application Process (Laminate over Laminate)

Apply the laminate over the existing laminate carefully. Ensure that one edge is properly aligned, and then gradually lay down the sheet, pressing firmly to avoid bubbles or wrinkles. If you are using contact cement, apply it to both surfaces, allow it to become tacky, and then press them together. Use a roller to apply even pressure and ensure a smooth application.

Application Process (Post-Forming Laminate)

For post-forming laminate, the application process is different. Clean the surface thoroughly using a mild detergent or acetone to remove any grease, dirt, or dust. If there are any chipped, cracked, or peeling areas, repair them before applying the new laminate. Start by aligning one edge of the laminate sheet and gradually lay it down, pressing firmly to avoid bubbles or wrinkles. Use a roller to apply even pressure.

Trimming Excess Material

Once the laminate is applied, trim any excess material with a router or a laminate trimmer. This step is crucial for achieving a clean, professional-looking edge. For post-forming laminate, trim the edges carefully to ensure they are flush with the existing surface.

Finishing Touches

Edge Banding: Consider applying laminate edge banding to cover any exposed edges for a polished look. This will not only enhance the aesthetic appeal but also protect the edges from moisture and chips. Sealing: Seal the edges of the laminate with a trim to provide extra protection against moisture and maintain a polished finish.

By following these detailed steps, you can laminate over laminate or post-forming laminate on your cupboard. This method allows you to refresh the appearance of your kitchen without the need for complete removal, saving you both time and effort.
