Plywood Cabinet Painting: A Step-By-Step Guide

Painting plywood cabinets can be a great way to give them a new lease of life, but it's important to do it properly to get a professional finish. The process is similar to painting any other type of wood, but there are a few key things to keep in mind. Firstly, preparation is key. Fill any holes or imperfections with wood filler and sand down the entire surface to create a smooth base for the paint. Next, apply a primer to seal the wood and help the paint adhere better. Once the primer is dry, you can start painting, using a foam roller or paint sprayer for best results. You may need to apply multiple coats of paint, allowing each coat to dry thoroughly before sanding and applying the next. Finally, consider sealing the paint with a varnish or other sealant, especially if the cabinets will be used in a high-traffic area or exposed to water.

Filling holes and imperfections

Before painting plywood, it is important to fill any holes or imperfections to ensure a smooth and flawless finish. Here is a step-by-step guide to filling holes and imperfections in plywood cabinets:

Step 1: Remove Cabinet Doors and Hardware

Start by removing the cabinet doors from their hinges and placing them on a flat surface. This will make it easier to work on the doors and access the screw holes. Use a screwdriver to unscrew and remove any hardware, such as handles or knobs, to expose the screw holes.

Step 2: Sand the Holes

Use a sanding block with 120-150 grit sandpaper to smooth out the surface around the holes. Sand until the surface is flush with the surrounding wood on both sides of the door. Make sure to wipe away any dust and debris with a microfiber cloth or a tack cloth.

Step 3: Apply Wood Filler

Use a plastic putty knife to spread wood filler into the screw holes on both sides of the cabinet door. Overfill the holes slightly, as you will sand them down later. Wood filler is recommended for painted surfaces, as it sands better and creates a smoother finish. Allow the wood filler to dry for at least a few hours, or overnight if possible.

Step 4: Sand the Wood Filler

Once the wood filler is completely dry, use 220-grit sandpaper to sand the surface smooth. Move in random circles to avoid leaving scratch marks that may show through the paint. After sanding, feel the patched area to check for any dips or differences in level. If necessary, apply a second layer of wood filler and repeat the process.

Step 5: Paint Over the Holes

If you know the colour of your cabinet doors, use the same paint to touch up the filled screw holes. If you are unsure of the colour, you can take a cabinet door to your local hardware store to get a colour match. You can use a brush to paint over the holes, and a dry foam roller to smooth out the paint and create a factory-finish look. You may need to apply multiple coats of paint to completely cover the screw holes.

Additional Tips:

• If you are filling holes in laminate cabinets, use wood putty instead of wood filler. Be cautious when filling the holes, as any excess putty on the surface of the cabinet can be difficult to remove once dry.
• For a completely seamless finish, consider using a paint sprayer or a technique called "laying off" or "tipping off". After rolling on the paint, gently run a good-quality paintbrush across the surface while the paint is still wet to create an extremely smooth finish.

Applying wood filler

Step 1: Prep the Plywood Cabinet Surface

If your plywood cabinet surface is unfinished, you can skip this step. However, if there is an existing finish, use 120-180 grit sandpaper to scuff up the surface. Remove any oils, dirt, debris, and dust with a moistened rag or tack cloth after sanding.

Step 2: Choose the Right Wood Filler

Select a quality, paintable wood filler that matches the colour of your plywood cabinets. Water-based fillers are generally recommended over solvent-based fillers as they are easier to work with, dry faster, and are more environmentally friendly.

Step 3: Apply the Wood Filler

Use a putty knife to apply the wood filler to the plywood cabinet surface. Ensure that you apply the filler against the grain to get it deeper into the grain and fill it better. Apply a thick coat and work it into all the pores. Let the filler dry for a few hours.

Step 4: Sand the Plywood Cabinet Surface

Once the wood filler is dry, use 120-220 grit sandpaper to sand the plywood cabinet surface. This will help create a smooth finish and remove any excess wood filler. Wipe down the surface with a damp cloth to remove any dust.

Step 5: Apply Primer and Paint

After sanding, apply a coat of primer to the plywood cabinet surface. Once the primer is dry, lightly sand the surface again and wipe away any dust. Then, apply your chosen paint colour, ensuring that you apply it along the direction of the wood grain.

Tips:

• If you are filling holes or cracks in the plywood cabinet, use wood putty. Apply a small amount with your hands, a putty pen, or a putty knife, ensuring there is no excess around the edges.
• Always follow the manufacturer's instructions for drying times and application methods.
• For a super-smooth finish, use a technique called "laying off" or "tipping off". After you've rolled on the paint, gently run a good-quality paintbrush across the surface while it's still wet.

Sanding the plywood surface

Before starting the sanding process, ensure that you have filled any dents, imperfections, knot holes, and nail or screw holes with a wood filler. Allow the filler to dry completely according to the manufacturer's instructions. Filling these holes and creating a smooth surface will ensure that your paint job looks uniform and flawless.

Once the filler is dry, it's time to begin sanding. Use a fine-grit sandpaper, such as 180-220 grit sandpaper, to sand the entire surface of the plywood cabinet, including the filler and edges. Sand in the direction of the wood grain to create a smooth and even finish. This step will help remove any excess filler and create a consistent surface for painting.

After sanding, use a damp cloth or a tack cloth to wipe down the plywood surface. This step is crucial to remove any dust or debris created during the sanding process. You can also use a shop vac to ensure that all the dust is removed from the cabinet and the surrounding areas.

If there are still minor imperfections or dents after the initial sanding, you may need to apply another coat of wood filler and repeat the sanding process. It is important to take your time during this step to ensure that the plywood surface is as smooth as possible before moving on to the next steps of priming and painting your plywood cabinets.

Once you are satisfied with the smoothness of the surface, you can proceed to the next steps of priming and painting your plywood cabinets. Remember to always sand in between coats of primer and paint to ensure a smooth and professional finish.

Additionally, if you are working with plywood edges, you can use a screwdriver to round out the edges before filling and sanding. This will create a smoother transition between the plywood surface and the edges, resulting in a more polished final product.

Applying primer

Step 1: Choose the Right Primer

Select a primer specifically designed for use on bare wood surfaces. Look for primers labelled as suitable for interior/exterior or wood surfaces. Oil-based primers, such as Zinsser BIN Shellac Primer, are ideal for kitchen cabinets as they provide excellent adhesion and stain-blocking properties.

Step 2: Prepare the Work Area

Before applying the primer, ensure the work area is well-ventilated as primer fumes can be strong. Wear protective gear, including a face mask and gloves, to avoid inhaling the fumes. It's also important to cover nearby surfaces and floors to protect them from primer splatters.

Step 3: Clean the Plywood Surface

Start by gently brushing the plywood surface with a smooth-bristled brush to remove any dust, debris, or foreign matter. Follow this step with a damp cloth to ensure the surface is thoroughly cleaned.

Step 4: Fill Imperfections and Sand the Surface

Use a wood filler or putty to fill any dents, exposed nails, or bumps on the plywood surface. Let the filler dry completely, following the manufacturer's instructions. Once dry, sand the entire surface with 180-220 fine-grit sandpaper to create a smooth base for the primer. Wipe away any sanding dust with a tack cloth or a slightly damp cloth.

Step 5: Apply the Primer

Using a foam roller, brush, or sprayer, apply the primer to the plywood cabinets. Work in the direction of the wood grain, ensuring you get into all the nooks and crannies. Apply multiple thin coats of primer, allowing each coat to dry before applying the next. Lightly sand between coats with 220-grit sandpaper to remove any roughness and create a smooth finish.

Step 6: Final Inspection

Once the final coat of primer has dried, inspect the surface for any imperfections, such as bumps or lumps. Lightly sand these areas and wipe away the dust. Ensure the surface is smooth and free of contaminants before proceeding to the painting stage.

Painting and sealing

Preparation:

Before starting the painting process, it is essential to prepare the plywood surface. This includes filling any dents, imperfections, knot holes, and nail or screw holes with a wood filler. Let the filler dry according to the manufacturer's instructions, and then sand the entire surface, including the filler and edges, to create a smooth base for the paint. Use a fine-grit sandpaper (180-220) for this step. Remove any dust from the surface with a damp cloth and a vacuum cleaner.

Priming:

The next step is to seal the plywood with a primer. For this, you will need a small paintbrush (2-inch) and a roller. Apply the primer in a V or W shape to ensure an even spread. Use the brush to even out the paint on the edges and areas with paint accumulation. Once the primer is dry, lightly sand the surface with fine-grit sandpaper (180-220) and wipe it clean with a damp cloth. Depending on the manufacturer's instructions and the desired finish, you may need to apply a second coat of primer, following the same process.

Undercoating:

Before applying the topcoat, you need to add an undercoat. Apply the undercoat in the same way as the primer, and allow it to dry. Lightly sand the surface and wipe away any dust. Depending on the desired finish, you may need to apply a second coat of undercoat.

Topcoating:

Finally, it's time to apply the topcoat. Follow the manufacturer's instructions for drying time and application. You may need to apply multiple coats for a smooth and durable finish.

Sealing:

To protect your paint job and ensure its longevity, consider adding a layer of paint sealant, especially if your cabinets are in a high-traffic area or are frequently exposed to water. The sealant will create a barrier against dust, contaminants, and moisture, keeping your cabinets looking fresh and new.
