How to Paint Over Tongue And Groove Pine Walls? A step-by-step guide

Painting over tongue and groove pine walls is a great way to update the look of any room. This wall style is popular in many homes because of its rustic, natural look.

While the wood is beautiful, it can become dated over time. Fortunately, it’s easy to paint over tongue and groove pine walls with suitable materials and techniques. Here’s a step-by-step guide to help you get the job done.

Materials Needed

  • Tongue and groove pine panels
  • Primer
  • Paint (latex or oil-based)
  • Paintbrushes (angled and straight)
  • Roller and roller cover
  • Painter’s tape
  • Drop cloths or plastic sheeting
  • Sandpaper (fine grit)
  • Tack cloth
  • Paint tray
  • Painters’ tape

Step-1: Preparation

  • Remove any furniture or fixtures from the area or cover them with drop cloths or plastic sheeting to protect them from paint splatters.
  • Clean the tongue and groove pine walls to remove dust, dirt, and grease or grime. Use a mild detergent and water, then allow the surface to dry completely.

Step-2: Repair and Sanding

  • Inspect the walls for imperfections, such as holes, dents, or gaps. Fill these with wood filler and allow it to dry. Sand the filled areas and any rough spots with fine-grit sandpaper until the surface is smooth and even.
  • Wipe down the walls with a tack cloth to remove any sanding dust.

Step-3: Priming

  • Apply a coat of primer to the tongue and groove pine walls. Primer helps the paint adhere better and provides a consistent base color. Use a brush for the edges and corners and a roller for larger areas. Let the primer dry according to the manufacturer’s instructions.

Step-4: Painting

  • Once the primer is dry, you can start applying the paint. Use a paintbrush to cut in along the edges and corners first. Then, use a roller to paint the larger areas. Roll the paint on in a “W” or “M” pattern to ensure even coverage.
  • Work in sections, usually a few boards at a time, to maintain a wet edge and prevent visible brush or roller marks. Blend each section into the previous one while the paint is still wet.

Step-5: Second Coat

Allow the first coat of paint to dry completely. Depending on the paint type and brand, this may take a few hours to overnight. Check the paint can for specific drying times.

Apply a second coat of paint following the same techniques as the first coat. This will help achieve a smooth and consistent finish.

Step-6: Finishing Touches

Once the second coat is dry, inspect the painted surface for any uneven areas or touch-ups that may be needed. Use a small brush to correct any imperfections.

Carefully remove the painter’s tape if you used it, pulling it back on itself at a 45-degree angle to avoid lifting the paint.

Step-7: Clean Up

  • Clean your brushes, rollers, and paint tray according to the manufacturer’s instructions. Proper cleaning prolongs the life of your painting tools.

Is the Paint Used for Fiberglass Doors Suitable for Painting Over Tongue and Groove Pine Walls?

When deciding on the best paint for fiberglass doors, it’s important to consider its use on other surfaces.

What to consider when choosing a paint roller for tongue and groove?

When tackling a tongue and groove project, using the right paint roller is essential for achieving the desired finish. Here are a few tips for choosing the best paint roller.


When choosing the right paint roller for your tongue and groove project, size is one of the most critical factors. A larger roller is generally better for covering larger areas, whereas a smaller roller is better for tight spaces and corners. If you’re unsure what size to get, a medium-sized roller is best because it can be used in wide, tight spaces.


There are several options for the roller’s material. Foam, synthetics, and wool are the most common materials. Smooth surfaces benefit from foam rollers, whereas rougher surfaces benefit from synthetic rollers. Wool rollers provide more even coverage on textured surfaces.


The finish of the paint roller is also an essential factor to consider when choosing the right one for your project. A foam roller is your best bet if you want a smooth finish. For a rougher finish, a synthetic roller is a way to go. And if you’re looking for a textured finish, a wool roller is the way to go.


When selecting the right one for your project, the paint roller price is also something to consider. Generally, foam rollers are the least expensive, followed by synthetic and wool rollers.

However, remember that you get what you pay for, so it’s best to opt for a higher-quality roller that will last longer and provide a better finish.

The Best Paint for Tongue And Groove

When painting tongue and groove surfaces, there are a few factors to consider when deciding on the best type of paint for the job. Consider the environment to which the tongue and groove will be exposed.

Will the surface be subjected to a lot of moisture or high temperatures? If this is the case, choose a paint specifically designed to withstand these conditions, such as a latex or oil-based enamel.

Determine whether you require a fading, mildew, or dirt-resistant finish. If so, look for paints with UV protection or mildew-resistant additives. Consider the look you want to achieve. Choose a semi-gloss or high-gloss paint for a glossy finish. Use a matte or eggshell finish for a more understated look.


Painting tongue and groove pine walls can be difficult, but you can achieve a stunning, professional-looking result with the right tools and techniques. Consider the size and type of roller you are using and the type of paint you are using when choosing a paint roller.

An oil-based primer, followed by an oil-based or latex paint, is the best type for the tongue and groove. Finally, use a brush for edging, a roller for the main surface, and a brush for cutting in when painting the tongue and groove.

Following these tips and techniques, you will get the best results when painting your tongue and groove pine walls. Thank you for reading!
