Preparation: Clean, sand, repair, and prime the trim
Painting plastic trim on laminate cabinets is a great way to modernise and refresh your kitchen. Preparation is key to achieving the best results. Here is a detailed guide to preparing plastic trim on laminate cabinets for painting:
Clean
Before you begin any work on your cabinets, it is important to clean the surface thoroughly. Use a wet rag or sponge to wipe down the cabinets, ensuring there is no dirt, grease, or residue left on the surface. Trisodium phosphate (TSP) is an effective cleaning agent, but it is banned in many communities. An alternative is to use diluted vinegar. Once cleaned, dry the cabinets with a clean cloth, and use a tack cloth to ensure the surface is completely dust-free.
Sand
Lightly sand the laminate surface with medium-grit sandpaper (180-220 grit) to create a rough texture. This will help the paint adhere better and create a more flawless finish. Use sweeping motions to sand the entire surface area. If you want to skip sanding, you can use a deglosser, which acts as a liquid sander and removes grease. After sanding, use a vacuum to remove any debris, and then wipe the surface with a microfiber towel or a damp cloth to remove any remaining dust.
Repair
Check the laminate for any damage and repair as needed. Use a waterproof adhesive to reattach any peeling laminate. If your cabinets have hardware, such as hinges or handles, you can choose to remove and replace them, or simply remove and reinstall them after painting.
Prime
To ensure the paint adheres correctly and to prevent chipping or peeling, it is important to use a primer. Laminate is essentially plastic, so a high-quality oil-based primer is recommended. You can use a disposable foam roller or brush for application. Apply the primer evenly to the entire surface, and allow it to dry completely before moving on to the next step.

Primer selection: Choose an oil-based primer for plastic
When painting plastic trim on laminate cabinets, primer selection is crucial to ensure the paint adheres well to the plastic surface. While laminate cabinets can be painted, they are not an ideal surface for paint to adhere to. Therefore, choosing the right primer for plastic is essential for a long-lasting finish.
An oil-based primer is an excellent choice for preparing plastic surfaces for painting. Oil-based primers, such as the Rust-Oleum Specialty Oil-Based Alkyd Spray Primer, offer superior adhesion and durability. They are designed to bond directly to plastic, creating a strong base coat that will help the paint stick to the plastic trim effectively. This type of primer is especially useful for challenging surfaces like plastic, where paint may not adhere well without proper preparation.
Oil-based primers are also advantageous because they can fill in any minor imperfections or scratches on the plastic surface. By creating a smooth and even base, the primer allows for a more seamless paint application. Additionally, oil-based primers provide a flexible base, which is beneficial for plastic surfaces that may expand and contract with temperature changes.
When selecting an oil-based primer for plastic trim, look for products specifically designed for plastic adhesion. Some primers may not adhere well to plastic, so choosing a primer that is marketed for use on plastic surfaces is essential. The primer should also be compatible with the type of paint you plan to use. Check the manufacturer's instructions and recommendations to ensure you select a suitable primer for your project.
Applying the oil-based primer to plastic trim is typically done through spraying or brushing. Spraying the primer provides a quick and efficient application, ensuring even coverage on the plastic surface. However, brushing the primer on with a high-quality paintbrush can also be effective, especially for smaller areas or intricate details on the trim.

Painting: Use a paintbrush or roller for an even coat
Painting plastic trim on laminate cabinets requires careful preparation and the right tools. Laminate is a synthetic material, often referred to as "fake wood", made of layers of paper and resins fused under high pressure. The surface is usually plastic, which is not very receptive to paint. However, with the right products and techniques, you can achieve a smooth and long-lasting finish.
Before painting, it is crucial to prepare the surface. Start by removing the cabinet doors and drawers and placing them on a flat surface. Remove all hardware, including hinges, and set them aside safely. Next, clean the laminate thoroughly to remove any dirt, grease, or residue. Trisodium phosphate (TSP) is an effective cleaner, but if it is banned in your community, use a substitute or an all-purpose cleaning wipe. You can also use diluted vinegar, followed by a thorough drying with a clean cloth.
Once the surface is clean, it's time to sand it lightly. Use medium-grit sandpaper (around 180-220 grit) in sweeping motions to create a rough texture that will help the paint adhere better. After sanding, use a vacuum to remove the debris and wipe the surface with a microfiber towel or a tack cloth to ensure it is completely dust-free.
Now, you are ready to start painting. Use a high-quality paintbrush or a fine-finish roller for the best results. Stir the paint thoroughly and pour it into a paint tray. Apply the paint evenly to all surfaces, using thin coats rather than one thick coat to avoid drips and runs. Pay special attention to corners and edges to ensure a smooth finish. If necessary, use a smaller artist paintbrush for detailed areas, such as the cabinet trim.
Depending on the desired colour and smoothness, you may need to apply multiple coats of paint. Allow each coat to dry completely before applying the next one. For the best results, wait at least one day between coats. After the final coat has dried, reinstall the hardware and return the doors and drawers to their places.

Paint type: Opt for oil- or latex-based paint
Painting laminate cabinets is an affordable way to give your kitchen a new look. Preparation is key to achieving the best results. Before painting, remove the cabinet doors from their frames and take off all hardware, including hinges. This is a good opportunity to switch the hardware for an easy update. Next, check the laminate for damage and repair any cracked or warped laminate. Use a waterproof adhesive to reattach any peeling laminate. Then, clean the cabinet doors and sand them lightly. To clean, wipe the cabinets with an all-purpose cleaning wipe or diluted vinegar. Dry them thoroughly with a clean cloth, and use a tack cloth to ensure the doors are dust-free.
When it comes to paint type, you can opt for oil- or latex-based paint. The type of paint is not as important as the use of primer, which will enable the paint to adhere to the laminate surface. However, you can use any oil- or latex-based paint suitable for painting wood on laminate cabinets. Before painting, apply a coat of primer to help the paint bind to the cabinets. Use a bonding primer, which is stronger than regular primer, to ensure the paint sticks to the laminate. The paint may quickly flake or peel if you skip priming the laminate cabinets.
Let the primer dry for four to six hours, then sand the cabinets gently with fine 220-grit sandpaper. Wipe away the dust with a tack cloth. For painting, use small foam rollers for large areas and a paintbrush for corners and crevices. Let the paint dry overnight and apply a second coat if needed. Finally, replace the hardware and hang the cabinets back onto the hinges.

Drying and curing: Allow paint to dry and cure before rehanging
Drying and curing are two different processes, and it is important to understand the difference to ensure the best results when painting plastic trim on laminate cabinets. Paint drying occurs when solvents in the paint evaporate, making the paint coating feel dry to the touch. However, this does not mean the paint is 100% dry or fully cured. The paint is 100% dry when it has reached its maximum hardness and is completely hardened and preserved.
The curing process is when the paint undergoes a complete transformation and reaches its maximum hardness and durability. This can take several days to weeks, depending on the paint type and environmental conditions. For example, water-based/latex paint has a dry time of 1-2 hours but needs 21-30 days to cure fully. Oil-based paint dries in 6-8 hours but takes 3-7 days to cure. Chalk brand paints, homemade chalky paint, and milk paint have shorter dry times of 30-60 minutes, 30-60 minutes, and 30 minutes, respectively, but they still need about 30 days to cure fully.
To check if your paint is dry, touch an inconspicuous area with your finger. If the paint is not tacky and feels dry, it is dry. To test if your paint has cured, do the fingernail test in an inconspicuous area. Press your fingernail gently onto the coating, and if it leaves an indent, your paint is not fully cured. If no indent is visible and the surface is hard, your paint has cured.
It is important to allow each coat of paint to dry completely before applying the next one. This will ensure that the paint adheres properly and help achieve a smooth and durable finish. Environmental factors such as room temperature, moisture levels, and ventilation can impact drying and curing times, so these should be considered when painting plastic trim on laminate cabinets.
