Painting plywood is a great way to achieve a smooth and long-lasting finish that can blend into any room in the home. It is a versatile and cost-effective material that can be used for various DIY projects, such as flooring, roofing, wall cladding, and furniture. When it comes to painting plywood, there are several options to consider, including brushes, rollers, and spray paint cans. While brushes provide more control and detail, rollers are a popular choice for achieving an even and smooth finish. In this article, we will specifically focus on the different types of rollers that can be used for painting plywood and how to choose the best one for your project.

What You'll Learn

Use a mini roller for edges and small areas
When painting plywood, a mini roller is ideal for painting edges and small areas. The longer the roller, the more surface area it covers. Therefore, shorter rollers are more suitable for edges and corners. A mini roller can be used to paint the edges of the plywood after taping them off. This will ensure that your work is tidy.
After applying wood filler and sanding the plywood, you can use a mini roller to apply the primer. The primer should be applied in a V or W shape to get an even spread of paint. A 4-inch mini roller is ideal for this purpose. A bigger 9-inch roller should be used for larger areas. You can also use a brush to even out the paint on the edges or any areas where paint has accumulated.
When choosing a mini roller, consider the fabric and nap size to achieve a seamless finish. Woven fabrics, such as microfiber and mohair, provide a smooth finish without leaving lint behind. Knit fabrics, like polyester and lambswool, hold more paint and cover larger areas faster but may leave some stipple. Low-nap rollers pick up less paint, while high-nap rollers are better for larger projects.
If you want an extremely smooth finish, you can use a sponge roller or rent a spray gun. However, using a sponge roller may require two layers of paint.

Choose a roller designed for the surface
When painting plywood, the type of roller you choose is important to achieve the best results. The most suitable roller will depend on the surface you are painting and the finish you want to achieve.
If you are painting a large area, a bigger roller is ideal. A 9-inch roller is recommended for covering larger sections of plywood. For smaller areas and edges, a mini roller (4-inch) is a better option as it allows for more precision.
The texture of the roller is also a key consideration. For a smooth finish, a 12mm roller is recommended. This size roller will give you an even paint film without splattering. For rougher surfaces, a thicker roller with a longer nap is needed. A 20mm roller is designed for textured surfaces like brickwork and will help you reach into all the grooves and crevices.
The type of paint you are using will also influence your roller choice. Rollers are designed to hold different amounts of paint, so consider whether you are using a paint that requires a thick or thin coat.
Additionally, you may want to opt for an "All Purpose" roller, which can be used on various surfaces. However, for the best results, it is recommended to use a roller designed for a specific surface and purpose.

Use a brush for detailed edges
Painting plywood is a great way to give it a smooth finish that blends into any room in your home. It is a versatile, cost-effective, and durable option for a range of DIY projects, from flooring to furniture. When it comes to painting plywood, you have several options, including using a roller, a brush, or a spray painter.
If you're painting plywood with a roller, you might wonder whether to use a brush for the detailed edges. The answer is yes! A paintbrush is ideal for detailed edges and smaller areas that require more precision and control. While a roller is perfect for covering large, flat surfaces quickly and efficiently, it can be challenging to manoeuvre it into tight corners and small inner corners. That's where a brush comes in handy.
A high-quality paintbrush will allow you to carefully apply paint to edges, corners, and tight spots, ensuring a neat finish. You can use painter's tape to mask off the edges before painting to ensure straight lines and a tidy result. Once the tape is in place, you can use your brush to paint along the edges, taking your time to achieve the desired level of detail.
Additionally, a brush is useful for applying primer to the edges of the plywood before painting. Priming the edges will help seal the surface and ensure that the paint adheres well. You can use a 2-inch brush to apply the primer in a ""V" or "W" pattern, ensuring even coverage. Once the primer is dry, you can lightly sand the edges and wipe them clean before applying the topcoat.
In summary, while a roller is excellent for large areas, a brush is the perfect tool for detailed edges when painting plywood. It gives you the precision and control needed to achieve a neat and professional finish.

Use a roller for larger areas
When painting plywood, you will need a roller, a paintbrush, and primer. The type of roller you use will depend on the area you are painting. For larger areas, a bigger 9-inch roller is ideal. These rollers are designed to hold a large volume of paint.
To start, paint a 3-4 inch border along the edges of the plywood with a paintbrush. This will give you clearance from the edges when you come in with your roller. Then, prime the surface using smooth, overlapping strokes. Apply the primer in a V or W shape to get an even spread of paint.
Once the primer is dry, you can apply your first coat of paint. Make sure to cover the entire surface with a consistent, thin coat of paint. When applying paint with a roller, do not press too hard. Ensure that the roller is soaked with paint, but not dripping. To maintain an even coat, do not let the roller slip or get matted down.
After the first coat of paint is dry, lightly sand the surface. Then, apply a second coat of paint.

Oil-based paint is best for a professional look
Oil-based paint is quite versatile and can be used on most materials. However, it requires a sealer or pre-treatment for masonry surfaces and should not be applied directly to galvanized metal. This type of paint is also durable and flexible, making it ideal for clear wood finishes and protective coatings. It provides a tough, glossy finish that can withstand the test of time.
To achieve a professional finish with oil-based paint, meticulous surface preparation is required. The surface must be clean and free of dust before painting. Priming the surface is also important, as it helps the paint adhere better and creates a more even finish. When thinning oil-based paint, it is important to read the instructions on the paint container, as not all oil-based paints can be thinned with a thinner; some may require special mineral spirits.
It is worth noting that oil-based paints have some negative qualities. They have higher levels of volatile organic compounds (VOCs), which can negatively impact the environment and human health. These compounds also cause oil-based paints to have a stronger odour during application and drying, so proper ventilation is crucial. Additionally, oil-based paints take significantly longer to dry than water-based paints, and the space must be kept dust-free for an extended period.
