How To Paint Wainscoting In A Bathroom – A Step-By-Step Guide

Wainscoting is a classic and elegant way to add depth and texture to any bathroom. But, if you’re looking to update your bathroom’s wainscoting, you might be wondering how to paint it.

Painting wainscoting can be a bit tricky, especially in high-humidity areas like bathrooms. However, with the right tools and techniques, you can achieve a beautiful and long-lasting finish.

In this article, we’ll guide you through the process of painting your bathroom’s wainscoting step-by-step, from priming to painting. So, let’s get started!

How To Paint Wainscoting In Bathroom

Step 1: Prepare the Surface

Before you begin painting, it’s important to prepare the surface of your wainscoting. Start by cleaning the surface with a mild detergent and water to remove any dirt or grime. Once the surface is clean, sand it lightly to create a smooth surface for the primer and paint to adhere to.

Step 2: Apply Primer

Even if your paint already has primer in it, we recommend giving your wainscoting a mold and mildew-resistant base coat, particularly in high-humidity areas like a bathroom. This will help lock out moisture and ensure better adhesion without needing to sand. Choose a primer that is labeled as “stain blocking” to hide any knots that could bleed through the paint. We recommend using Zinsser Bulls Eye 1-2-3 Primer since it does all of the above and dries within an hour.

Start by priming inside the grooves of the wainscoting with a 2-inch angled sash paintbrush. Move the brush up and down for vertical paneling or side to side for horizontal paneling. If you plan to paint the trim and baseboards to match the wainscoting, don’t forget to prime those as well.

Step 3: Paint

Once the primer is dry, it’s time to paint your wainscoting. Use a similar application when painting the paneling, using either a medium paintbrush or paint roller. Begin by painting along the top and bottom edges where the wainscoting meets the wall and floor. Paint the indented panels and the molding around them using up-and-down strokes on the vertical areas and back-and-forth strokes on the horizontal areas.

After waiting for the paint’s maximum recoat time, apply an even second coat of paint in the same way you did the first coat. Remove any painter’s tape immediately after you’ve finished your second coat of paint to prevent paint from peeling off with the tape.

Allow the paint to dry and cure completely before returning the area to everyday use.

Preparing The Surface

Before you start painting your wainscoting in the bathroom, it’s important to prepare the surface. The first step is to remove any fixtures or hardware that may be in the way. This includes light fixtures, switch plates, and furniture. You should also turn off the water supply to the toilet and remove the tank to make it easier to paint near it.

Next, patch any holes on the wall using a wall joint compound or spackle. Once the compound has dried, sand the surface lightly to create a smooth surface for the primer and paint to adhere to.

It’s important to ensure that the walls and ceiling are completely clean before painting. Use a cleaning solution of one part bleach to three parts warm water to remove any dirt or grime. When the walls are completely dry, cover the areas that need to be protected from paint. Place tarps or plastic sheets on the vanity, bathtub, sink, and floor.

After masking off any areas that you don’t want to paint, apply primer to the surface. Even if your paint already has primer in it, we recommend giving your wainscoting a mold and mildew-resistant base coat, particularly in high-humidity areas like a bathroom. Choose a primer that is labeled as “stain blocking” to hide any knots that could bleed through the paint.

Start by priming inside the grooves of the wainscoting with a 2-inch angled sash paintbrush. Move the brush up and down for vertical paneling or side to side for horizontal paneling. If you plan to paint the trim and baseboards to match the wainscoting, don’t forget to prime those as well.

Once the primer is dry, you can start painting your wainscoting. Use a similar application when painting the paneling, using either a medium paintbrush or paint roller. Begin by painting along the top and bottom edges where the wainscoting meets the wall and floor. Paint the indented panels and the molding around them using up-and-down strokes on the vertical areas and back-and-forth strokes on the horizontal areas.

After waiting for the paint’s maximum recoat time, apply an even second coat of paint in the same way you did the first coat. Remove any painter’s tape immediately after you’ve finished your second coat of paint to prevent paint from peeling off with the tape.

Allow the paint to dry and cure completely before returning the area to everyday use. By following these steps, you can ensure that your wainscoting looks professional and lasts for years to come.

Choosing The Right Paint

When it comes to painting wainscoting in a bathroom, choosing the right paint is crucial. You need a paint that can withstand the moisture present in the room and is durable enough to handle the conditions. A high-quality paint designed to withstand moisture is essential, as moisture can quickly degrade paint and cause it to peel, crack or become discolored.

Semi-gloss or high-gloss finish paints are the best options for bathroom wainscoting, as they are more moisture-resistant than eggshell or flat finishes. They also have better dirt and stain resistance, making them easier to clean. Additionally, a gloss finish can add a touch of shine to the room, making it look more attractive.

Depending on the material the wainscoting is made from, oil- or water-based paints are available. Oil-based paints have a longer life and are more durable, but require more maintenance and are messier to clean up. Water-based paints are easier to wash up, but may not last as long.

Regardless of the type of paint used, it is important to properly prime and seal the wainscoting first before applying the paint. This ensures that it adheres to the surface and withstands moisture. Choose a primer that is labeled as “stain blocking” to hide any knots that could bleed through the paint.

We recommend using Regal® Select Interior paint for wainscoting, which offers excellent hide and uniform finish and is available in 3,500+ Benjamin Moore colors. For high-humidity areas like a bathroom, it’s essential to choose a paint that is mold and mildew-resistant.

Priming The Wainscoting

Before painting your wainscoting, it’s important to prime it to ensure that the paint adheres properly and to prevent any moisture damage. Here’s how to prime your wainscoting:

1. Choose the Right Primer: Select a primer that is suitable for your wainscoting material. If your wainscoting is made of wood or fiberboard, use a shellac- or latex-based wood primer to seal the grain and improve adhesion. If you’re painting over an existing coat of paint, choose a primer that is labeled as “stain blocking” to hide any knots and stains that could bleed through the paint.

2. Apply the Primer: Use a 2-inch angled sash paintbrush to apply the primer inside the grooves of the wainscoting. Move the brush up and down for vertical paneling or side to side for horizontal paneling. Make sure to cover all areas of the wainscoting, including the trim and baseboards if you plan on painting those as well.

3. Wait for the Primer to Dry: Allow the primer to dry completely according to the manufacturer’s instructions before applying paint. This usually takes around one hour.

By priming your wainscoting before painting, you’ll ensure that the paint adheres properly and lasts longer, while also protecting against moisture damage.

Painting The Wainscoting

When painting the wainscoting, it’s important to use a similar application method as when applying the primer and paint. Start by painting along the top and bottom edges where the wainscoting meets the wall and floor. Use up-and-down strokes for the vertical areas and back-and-forth strokes for the horizontal areas.

If you plan on spraying the wainscoting panels, you can use a semi-gloss paint finish. However, if you’re brushing the panels, it’s recommended to use a satin paint finish as it is more forgiving and will not show imperfections like seams and nail holes.

Remember to remove any painter’s tape immediately after finishing your second coat of paint to prevent any peeling. Allow the paint to dry and cure completely before returning the area to everyday use.

While some people may recommend using oil-based paint, experts now feel that waterborne alkyd paints are a better option as they are durable, do not yellow over time, and do not have a strong smell. Additionally, good quality interior latex paint is a great option for wainscoting as it lasts a long time and self-levels for a nice appearance overall.

By following these steps and tips, you can easily paint your wainscoting in your bathroom and give it a fresh new look while also protecting it from moisture.

Tips For A Professional-Looking Finish

1. Choose the Right Paint Color: It’s essential to select a paint color that works well with the overall theme of your bathroom. You can use a color selection guide to help you choose the perfect shade. If you’re unsure, consider purchasing color samples to test before committing to a full can of paint.

2. Use High-Quality Paint: For wainscoting, we recommend using Regal® Select Interior paint, which offers excellent hide and uniform finish. It’s also available in 3,500+ Benjamin Moore colors.

3. Apply Paint Evenly: When painting the wainscoting, use a paintbrush or roller to cut in the paint by applying an even amount along the edges of the wainscoting. Then fill in the remaining project surface with an even coat of paint. This will ensure a smooth and professional-looking finish.

4. Paint in Two-Foot Sections: When painting the flat part of the beadboard, apply a thin layer of paint in two-foot sections at a time. This will help you keep a “wet edge” as you work and prevent any unsightly brush or roller marks.

5. Back Brushing: If you notice any texture left by the roller, you can smooth it out by feathering it with your paintbrush—this is known as “back brushing.” This technique will help you achieve a perfectly smooth finish.

6. Choose Colors that Define Your Theme: To create a cohesive look, choose colors that define the theme you’ve chosen for your bathroom. For example, if you want a nature-inspired decor or a spa ambiance, work with tones of green, beige, and gray combined with white.

By following these tips, you can achieve a professional-looking finish when painting wainscoting in your bathroom.

Maintaining Your Newly Painted Wainscoting

Congratulations on painting your wainscoting! Now that you’ve completed the project, it’s important to maintain your newly painted surface to ensure its longevity. Here are some tips for maintaining your wainscoting:

1. Avoid Harsh Cleaners: When cleaning your wainscoting, avoid using harsh chemicals or abrasives that can damage the paint. Instead, use a mild detergent and water solution to wipe down the surface. Be sure to dry the surface completely after cleaning.

2. Touch Up as Needed: Over time, your wainscoting may experience some wear and tear, such as scratches or scuffs. If this happens, touch up the affected area with a small brush and matching paint. This will help maintain the appearance of your wainscoting.

3. Prevent Moisture Buildup: Since wainscoting is often found in bathrooms and other high-humidity areas, it’s important to prevent moisture buildup. Use a dehumidifier or open a window during and after showering to prevent excess moisture from accumulating on the surface.

4. Be Careful with Furniture: When moving furniture around in the room, be careful not to scratch or bump into the wainscoting. Use furniture pads or felt protectors on the bottom of furniture legs to prevent damage.

By following these simple maintenance tips, you can keep your newly painted wainscoting looking great for years to come!
