Painting plastic laminate is a great way to upgrade your furniture. It is important to prepare the surface before painting to ensure the paint adheres properly and does not peel off. This includes cleaning the surface with a damp cloth and thoroughly sanding the laminate to create a rough surface for the paint to stick to. After sanding, the surface should be wiped with a damp cloth to remove any remaining residue. The next step is to apply a primer designed for glossy surfaces, such as INSL-X® STIX® Primer, which offers powerful adhesion properties. It is important to let the primer dry completely before applying an even coat of paint with a brush or roller.

Sand the surface with medium-grit sandpaper to create an even, chalky finish
Sanding is an important step in preparing plastic laminate for painting. It helps create a surface that the paint can adhere to, which is crucial since laminate is a smooth and nonporous material. When sanding, it is recommended to use medium-grit sandpaper, such as 220-grit or finer, to create an even and chalky finish. If the laminate surface is high-gloss, a liquid de-glosser may also be used before sanding.
Start by wrapping the sandpaper around a block of wood or a sanding block to make the process easier. Then, using sweeping motions, sand the entire surface of the laminate piece. Go with the grain, moving the sandpaper back and forth in the direction of the laminate strips. Be careful not to apply too much pressure or sand for too long, as the laminate surface is delicate and can be easily damaged. The goal is to create a uniform, chalky finish across the entire surface.
Vacuum the laminate piece to remove any sanding dust, and then wipe it down with a damp cloth to eliminate any remaining residue. For an oil-based polyurethane finish, use a cloth dampened with mineral spirits, and for a water-based urethane finish, use a damp cloth. It is important to ensure that all dust and residue are removed before proceeding to the next step.
Once the laminate surface is thoroughly sanded, vacuumed, and wiped down, it is ready for the next step, which is priming. Primer is essential when painting laminate because it provides a surface for the paint to adhere to and helps the paint last longer. Choose a primer designed for glossy surfaces, such as a bonding primer like INSL-X® STIX®, which offers strong adhesion even to shiny surfaces. Apply the primer evenly to the entire surface of the laminate piece and let it dry completely before moving on to the painting step.

Vacuum and wipe the surface to remove any debris and residue
Before you start priming and painting plastic laminate, it is important to clean the surface thoroughly. Use a vacuum to remove any debris, such as dirt or dust, that may be present on the surface. This is an important step as any debris left on the surface can contaminate the finish. After vacuuming, wipe the surface with a damp cloth to remove any remaining residue. If you are using an oil-based polyurethane, dampen the cloth in mineral spirits. For a water-base urethane, dampen the cloth with water.
It is also recommended to sand the surface before priming and painting. Sanding helps to create a rough surface for the paint to adhere to. However, it is important to note that laminate is essentially paper, so be careful not to sand too much. Use a medium-grit sandpaper, such as 220-grit or finer, and sand in sweeping motions across the entire surface. You can also use a liquid de-glosser to roughen the surface. After sanding, be sure to vacuum and wipe the surface again to remove any dust or residue created during the sanding process.
Once the surface is clean and free of any debris or residue, it is ready for priming and painting. It is important to use a primer designed specifically for glossy surfaces, as this will ensure that the paint adheres properly. Follow the manufacturer's instructions for the best results. Allow the primer to dry completely before applying paint.

Apply the primer evenly across the surface and let it dry completely
When applying the primer, use a high-quality paintbrush or a fine finish roller to ensure an even application across the entire surface of the piece of furniture. It is important to apply the primer evenly and not to miss any spots, as the primer will help the paint adhere to the plastic laminate surface.
The primer should be allowed to dry completely before moving on to the next step. This is a crucial step, as it will ensure that the primer is effective in creating a surface to which the paint can adhere. The amount of time needed for the primer to dry will depend on the type of primer used. Some primers, such as Zinsser's oil-based primer, dry in as little as two hours. However, other primers may require a longer drying time, such as the water-based version by Zinsser, which is recommended to fully cure for seven days. It is important to follow the instructions on the primer can and to allow for adequate drying time to ensure the best results.
During the drying process, it is important to ensure that the primed surface is not disturbed. Avoid touching or moving the piece of furniture until the primer is completely dry. It is also advisable to work in a well-ventilated area or outdoors to speed up the drying process and to avoid inhaling any fumes from the primer.
Once the primer is completely dry, you can proceed to the next step, which is applying the paint. It is important to follow the specific instructions for the paint you have chosen, as the drying and application process may vary depending on the type of paint and the number of coats required.

Paint the surface with your chosen paint, using a brush or roller, and allow it to dry
Painting plastic laminate is a simple process, but it requires the right tools and preparation. Once you have sanded and primed the surface, you can begin to paint.
When painting plastic laminate, it is important to use a high-quality paintbrush or a fine finish roller. You can use the paint type you prefer, but it is recommended to use a brush for the corners and a roller for the flat surfaces. For heavier or larger pieces, work in a downward motion toward the legs. Always watch for drips and runs, especially at joints, corners, and fine woodworking details. You can use either ADVANCE® Interior Paint or INSL-X® Cabinet Coat.
Apply an even coat of paint to the surface, and allow it to dry completely before deciding if you need to apply another coat. You may need to apply an additional coat or two of paint to achieve the desired smoothness of your finished piece. Make sure you let each coat dry completely before applying another. For the best results, it is recommended to wait one day between coats.
If you are using a spray paint, it is important to note that you do not need to roughen the surface too much. In fact, when using catalyzed automotive primer/sealers, using too rough a sanding grit on the laminate can interfere with adhesion. The chemical cross-linking by the catalyst can cause the drying paint to pull away from deep scratches, leaving less paint sticking to the painted surface.
