Painting wood paneling is a great way to update the look of a room. Before painting, it is important to prepare the surface by cleaning it with a damp cloth or sponge to remove any dust, dirt, or grime. If there is old paint on the surface, it is recommended to test it for lead before sanding. If the paint contains lead, skip the sanding step and apply a primer to ensure the new paint adheres properly. If the paneling is glossy, a light sanding may be necessary to create a dull surface that the paint can adhere to. After sanding, it is important to wipe away any dust with a damp cloth or vacuum before applying a primer. Using a good-quality primer will help the paint adhere to the surface and improve the final look.
Do I have to sand my paneling before painting?
| Characteristics | Values |
|---|---|
| Sanding | Sanding is not always necessary. If the paneling has a glossy finish, a light sanding may be needed to create a lightly gritty surface so the paint will adhere. |
| Priming | Priming is critical when painting over wood paneling, even if it's fake. It helps the paint grip the surface and ensures better adhesion. |
| Cleaning | The paneling should be cleaned with a damp rag or sponge to remove dust, dirt, and grime. Degreasers can be used for stubborn dirt. |
| Filling | Holes, cracks, and seams should be filled with caulk or spackle before painting. This ensures a smooth surface and prevents dark edges where panels join. |

Sanding is not always necessary, but it can improve adhesion
Sanding is not always necessary when painting panelling, but it can improve adhesion. If you want to avoid sanding, you can simply apply a good primer to ensure the paint job will stick. An oil-based primer is a good option for this, as it will aid against bleed-through and help the paint grip the panelling.
However, if the panelling is too glossy, a light sanding may be necessary to create a rougher surface for the paint to adhere to. This is especially important if you are dealing with veneer, as sanding can ruin the thin outer layer, exposing the fiberboard underneath. In this case, it is crucial to be gentle and only sand enough to take off the sheen.
If you do choose to sand your panelling, it is important to properly prepare the surface. Start by cleaning the panelling with a damp rag or sponge to remove any dust, dirt, or grime. If there are layers of grime, you may need to use a degreasing cleaner or a solution of trisodium phosphate (TSP) and water. Once the surface is clean, you can begin sanding with 150-grit sandpaper, being careful not to sand too hard or too much in one area.
After sanding, be sure to wipe down the surface with a damp cloth to remove any dust. Then, apply a thin coat of primer to the panelling, using a roller or brush. Allow the primer to dry for at least 24 hours before painting. By following these steps, you can ensure that your paint job will have the best possible adhesion, even if you choose not to sand.

Use a primer to ensure paint adhesion and avoid bleed-through
If you want to paint your panelling, you should first prepare the surface by cleaning it with a damp rag to remove dust, dirt and cobwebs. If there are layers of grime, use a solution of TSP (trisodium phosphate) or a TSP substitute, which is less toxic, and water. You should never paint over a dirty surface because the paint won't adhere properly and will pick up clumps of dirt.
Next, you should use a primer to ensure paint adhesion and avoid bleed-through. Primers are critical when painting over wood panelling, even if it's fake. They help the paint grip to the surface. If you don't want to sand your panelling, using a primer that will stick to the old finish means you can skip sanding. However, if the primer doesn't stick well, your paint won't either, so it's important to choose a good-quality primer. Oil-based primers are a good choice for aiding adhesion and preventing bleed-through. Shellac-based primers are also effective at preventing tannin bleed-through and can be used as a standalone sealer or as a base coat. Clear shellac is a good option as it dries quickly and can be recoated within an hour of the first coat. For maximum stain-blocking ability, apply two coats and leave it to dry overnight before painting.
If you're using a water-based paint, be aware that some types of wood are more prone to tannin bleed-through. Oak, walnut, cherry and mahogany all have high concentrations of tannins, which can seep through the paint and manifest as dark stains. To avoid this, use a stain-blocking primer such as BIN Shellac-Based Primer, which is tinted white to help you see where it has been applied. Cover Stain oil-based primer is another option that provides excellent adhesion for both latex and oil-based paints while also blocking tannin stains. If you're looking for a water-based primer, General Finishes Stain Blocker is a high-solid-content stain-blocking primer, although it is quite expensive.

Clean the panelling with a damp rag or sponge to remove dust and dirt
Before painting panelling, it is important to clean the surface to ensure the paint adheres properly. Use a damp rag or sponge to wipe down the panelling and remove dust, dirt, and cobwebs. If there are layers of grime, use a solution of trisodium phosphate (TSP) or a less toxic TSP substitute mixed with water. You can also use a mixture of warm water and dish soap, followed by a clean, wet sponge to rinse off the soap. If any dirt remains, try using a heavy-duty degreaser.
It is crucial to never paint over a dirty surface, as the paint will not adhere properly, resulting in an uneven and low-quality finish. The paint may pick up clumps of dirt, creating an undesirable look. Therefore, cleaning the panelling before painting is a necessary step to ensure a smooth and clean final product.
After cleaning, dry the panelling with a soft microfiber towel or allow it to air dry completely. This step ensures that the surface is thoroughly prepared for the next steps in the painting process, such as sanding or priming.
Once the panelling is clean and dry, you can decide whether to proceed with sanding. Sanding is optional and may not be necessary if you use a good primer. However, if the panelling has a glossy finish, a light sanding can help create a dull surface that the paint can better adhere to. Remember to always wear a mask and goggles when sanding to protect yourself from dust and debris.
If you choose to sand, use 150-grit sandpaper or a finer 260-grit sandpaper to lightly sand the panelling. The goal is to remove the sheen and create a slightly gritty surface without overdoing it. After sanding, use a damp cloth or a product like TSP to remove any residual dust or debris.

Use a degreaser to remove any grease, grime, or residue from cleaning products
When it comes to painting paneling, one of the crucial steps is ensuring the surface is clean. While sanding is often recommended to create a gritty surface that paint can adhere to, it is not always necessary. A good alternative to sanding is to use a degreaser, such as trisodium phosphate (TSP), to remove any grease, grime, or residue from cleaning products. Here's a step-by-step guide on how to use a degreaser effectively:
Prepare the Degreaser Solution:
Start by mixing trisodium phosphate with water. You can find TSP at most home improvement stores, and it is a powerful cleaner that will help remove stubborn grease and grime. Always follow the instructions on the product label for the appropriate mixing ratio.
Protect Yourself:
Before you begin, it is important to put on protective gear, such as rubber gloves and safety goggles. TSP is a strong chemical, so ensure adequate ventilation in the area by opening windows or using fans.
Test on a Small Area:
Apply the TSP solution to a small, inconspicuous area of the paneling to ensure it doesn't cause any discoloration or damage to the surface. This is especially important if your paneling is made of a delicate material.
Apply the Degreaser:
Using a clean sponge or cloth, apply the TSP solution to the paneling, working in small sections. Pay close attention to areas with visible grease, grime, or residue. Follow the instructions on the product for the recommended contact time.
Wipe and Rinse:
After the degreaser has had sufficient time to work, use a clean, damp cloth to wipe away the solution. Ensure you rinse and wring out your cloth frequently during this process to avoid redistributing the grease and grime. Finally, go over the surface with a fresh, damp cloth to remove any remaining residue, and then dry the surface thoroughly.
By following these steps, you will effectively remove any grease, grime, or residue from cleaning products, preparing your paneling for a smooth and professional-looking paint job. Remember always to spot-test your cleaning methods and be cautious when working with strong chemicals like TSP.

Choose the right paint for the room, considering factors such as moisture and traffic
When it comes to choosing the right paint for a room, several factors come into play, especially if the room experiences high foot traffic or varying levels of moisture. Here are some considerations to help you make the right choice:
Moisture Levels:
If the room is a high-humidity environment, such as a bathroom, laundry room, or kitchen, you'll want to opt for paint with higher moisture resistance. Look for paints designed for high-moisture areas, such as those with a semi-gloss, gloss, or pearl finish. These finishes offer increased durability and resistance to moisture.
Foot Traffic:
For high-traffic areas, both indoors and outdoors, choose a paint that can withstand wear and tear and frequent cleaning. Semi-gloss and gloss finishes are ideal for these spaces as they are more durable and resistant to stains and scuffs. If you're painting a room with young children or heavy foot traffic, a semi-gloss finish is a good choice as it is easier to clean and less likely to show marks. Satin finishes are also a good option for high-traffic areas as they offer better stain resistance and durability than lower sheens.
Sheen and Light Reflection:
Consider the level of sheen or gloss in the paint, as this will determine how much light reflects off the painted surface. High-gloss finishes offer a mirror-like finish and are ideal for areas that need frequent cleaning. Satin finishes provide a delicate sheen, falling between matte and semi-gloss, giving a subtle gleam without being overly glossy. Matte finishes, on the other hand, are nearly shine-free and are suitable for bedrooms and dining rooms.
Colour and Visual Appeal:
When choosing a colour for high-traffic areas, consider the potential for dirt and stains. Darker colours tend to hide dirt and stains better than lighter shades, but they may absorb more heat, causing the paint to fade faster. Lighter colours can provide a cooler surface in sunny environments. If you're using a semi-gloss finish, avoid very bright colours as they can cause visual tension in the room due to the reflection.
Primer and Surface Preparation:
If you're painting over wood panelling, proper surface preparation is key. Clean the panelling with a damp rag or a TSP (trisodium phosphate) solution for heavily soiled areas. You can then apply a thin coat of primer to the panelling—an oil-based primer will help the paint adhere better, especially if the panelling has a shiny surface. While sanding is optional, lightly sanding the panelling with fine-grit sandpaper can help create a gritty surface for better paint adhesion. Just remember to wipe away any sanding dust with a damp cloth before priming.
