Redoing a plastic laminate countertop is a great way to give your kitchen a fresh look without breaking the bank. There are several ways to go about this, from using contact paper or paint to more intensive methods like applying epoxy or installing new laminate. If your laminate countertop is in relatively good condition, you can refinish it by sanding, sealing, and polishing it. If you want to change the colour, you can paint it or use a countertop coating, which can be tinted to your desired shade. For a more permanent solution, you can glue new laminate directly onto the old laminate or opt for a full replacement.

What You'll Learn
Sanding the surface
Start by assessing the condition of your counter. If there are minor scratches and blemishes, you can use fine-grit sandpaper, such as 220-grit, to gently sand the surface and remove these imperfections. If the counter is in a more deteriorated state, with deeper scratches or peeling laminate, you may need to use a more coarse grit, such as 60-grit, to start the sanding process. Always wear a dust mask and eye protection during the sanding process to avoid inhaling dust or debris.
Once you have chosen the appropriate grit sandpaper, begin sanding the entire surface of the counter. Pay close attention to the areas that are particularly damaged or uneven. Use a diamond-embedded sanding block or an electric sander for efficiency and to ensure an even finish. Sand in the direction of the grain if you are working with wood laminate. Be thorough, but also be careful not to apply too much pressure, especially if you are using a lower grit sandpaper, as you do not want to create dents or damage the substrate.
After sanding, your counter will likely be covered in dust and debris. Use a damp cloth or a soft brush to wipe away the residue. You can also use a vacuum to ensure that all the dust is removed from the surface and the surrounding areas. Once the counter is clean, you can proceed with the next steps of your refinishing project, such as applying a primer or paint.
If you are planning to apply a new coat of sealant or finish to your plastic laminate counter, you will also need to lightly sand the surface between coats. After applying the first layer of sealant, let it dry completely, then use fine-grit sandpaper to gently sand the surface until it is smooth. Repeat this process for each subsequent layer of sealant, always allowing the previous coat to dry and then sanding it before applying the next one.
Remember, when sanding plastic laminate counters, it is important to create a rough surface that will allow the new finish to adhere properly. However, be cautious not to over-sand or apply too much pressure, as this can damage the substrate or create an uneven finish. Take your time, use the appropriate grit sandpaper for the condition of your counter, and always follow the manufacturer's instructions for the products you are using.

Applying an adhesive
When applying an adhesive to plastic laminate countertops, there are several options and steps to consider. Firstly, determine if you are repairing existing laminate or installing new laminate sheets. For repairing chips and peeling laminate, a construction adhesive can be used to reattach the laminate to the substrate. Use clamps to hold the counter in place while the adhesive dries, and consider using paint stir sticks beneath the clamps to avoid dents or an uneven edge.
If you are installing new plastic laminate sheets over existing countertops, there are a few methods to consider. One option is to use contact cement as an adhesive, but this can be challenging to remove if needed. Another method is to use a special adhesive designed for applying new laminate directly over old laminate. This method may be more convenient, but there is a risk of chipping the new laminate due to the existing bevel.
Before applying any adhesive, ensure that the surface is properly prepared. Clean the surface with mild soap and water, and allow it to dry completely. You may also need to sand the laminate to create a rough surface that will help the adhesive or paint stick better. If repairing chips or cracks, fill them with adhesive or putty before proceeding.
Once the surface is prepared, apply the adhesive according to the manufacturer's instructions. Use a putty knife or similar tool to spread the adhesive evenly, ensuring complete coverage. Carefully position the new laminate sheet, taking care not to chip or damage the edges. Use clamps or weights to hold the laminate in place while the adhesive dries, following the recommended drying time for your chosen adhesive.
After adhering the new laminate, you may need to sand and refinish the edges for a smooth, seamless finish. Additionally, consider applying a layer of sealant to protect the surface and enhance its appearance. Allow the sealant to dry, and repeat the process as needed for a flawless finish. Finally, clean and polish your newly laminated countertop to maintain its glossy and smooth appearance.

Using a countertop kit
If you're looking to give your plastic laminate countertops a new look without breaking the bank, you can use a countertop refinishing kit. These kits are designed to transform old countertops and are a great option for DIYers. The process is straightforward, but it's important to follow the instructions included in the kit carefully for the best results.
Before you begin, it's essential to prepare the surface by giving it a thorough deep clean. Use a soft microfiber cloth with warm water and dish soap to remove any dirt, grease, or residue. If there are any chips or scratches, fill them with laminate repair paste or a colour-matched repair pen. Once the surface is clean and dry, you may need to sand it lightly to create a rough surface that will help the new finish adhere properly. Be sure to wear a dust mask and eye protection during this step, as it can be dusty.
When the surface is prepared, you can start applying the products in your kit. Most kits include pre-selected paints, brushes, rollers, and finishing coatings. Follow the instructions for your specific kit, as application methods may vary. Typically, you will apply the paint in thin layers, building up to achieve the desired effect. Some kits may include multiple tones of paint to create a mottled, granite look.
After painting, you will likely need to apply a clear sealer to protect the new finish. Again, follow the instructions for your specific kit regarding drying and curing times. Keep in mind that some clear coats may yellow over time, so be aware of this possibility when choosing a colour for your countertops.
Using a countertop refinishing kit is a budget-friendly way to transform your plastic laminate countertops. The process is relatively simple, but it requires some time and effort. With the right tools and careful preparation, you can achieve a beautiful, durable finish that will refresh your space.

Painting the surface
Firstly, you'll need to prepare the surface. Use 220-grit sandpaper to gently sand the surface, removing any scratches and blemishes. If your counter has chips, fill them with construction adhesive, clamping the counter until the adhesive dries. Then, give the counter a good scrub with soap and water and let it dry.
Now you're ready to start painting. Tape off any areas you don't want to be painted, such as the fridge, sink, and backsplash, and cover the floors and cabinets with a dust sheet. Start painting from the back, working your way forward. Use a foam brush to paint a thin layer, working your way into any crevices. Be sure to choose a durable paint that is purpose-made for countertops, such as Rust-Oleum. You can also use a countertop paint kit to achieve a decorative faux concrete, marble, or granite finish.
If you're using a two-part paint, be sure to mix equal amounts of each liquid in a disposable container, stirring vigorously with a wooden paint stick. Don't skimp on the stirring, as your project will not set properly if you do. You should see bubbles forming in the mixture as you stir.
Once you've finished painting, you'll need to seal and cure the surface. Apply a layer of sealant and sand it lightly once it dries. Repeat this process two more times, and then let the final coat of sealant dry for 24 hours to complete the refinishing process.

Sealing and curing
When choosing a sealant, opt for a resin, acrylic, or polyurethane coating specifically labelled for use as a laminate countertop sealant. Polyurethane coatings and resin sealants will add shine and provide a protective coating. For smaller spaces, an acrylic sealer is an affordable option. If you're sealing seams in laminate countertops, a two-part colour-matching epoxy or a jig that cuts both pieces simultaneously can be used. It is important to keep the seams away from the sink area as much as possible.
Before applying the sealant, tape off the areas you want to protect, such as the walls and backsplash, using painter's tape. This will help create an even joint and prevent any unwanted areas from being affected by the sealant. For the actual sealing process, cut the nozzle of the sealant cartridge at a 45-degree angle and insert it into a caulk gun. Apply the sealant along the joint between the countertop and the wall or backsplash. Smooth the bead of sealant with a caulk finishing tool or your gloved finger, then remove the painter's tape.
Allow the sealant to cure and dry completely before using the countertop. The curing time may vary depending on the type of sealant used and the environmental conditions, such as humidity. Refer to the manufacturer's instructions for specific curing times and conditions. During the curing process, ensure proper ventilation in the area and avoid any contact with the sealant. Once the sealant is fully cured, your plastic laminate countertop will be ready for use, and you can resume your regular kitchen activities.
