Painting rooms or items in your home is already a complex project on a basic level, but painting certain surfaces can be even more complicated. Wood surfaces require some extra steps before painting to ensure a smooth and clean looking paint job. If you’re wondering how to paint baseboards, moldings, or even wooden furniture for a professional and perfect final product, you’ve come to the right place.
Let’s dig into the preparation process for preparing wood for a new paint job.
Preparing your workspace
The first step in preparing for a big painting job is to prep your workspace. If you’re painting a wooden wall, baseboards, or moldings, you’ll need to tape off the area so that the paint doesn’t drip or seep onto areas you do not intend to paint.
Whether you’re painting walls, trim, or a piece of furniture, you’ll need to lay down protective tarps to protect your floors from paint drippings and splatters. If you’re painting an item or a piece of furniture, it’s recommended first to lay down a plastic tarp or sheet, followed by a canvas or paper covering, which will minimize slipping during the painting process.
Many steps in the process of prepping wood for painting pose risks to your eyes, skin, and even your lungs. Be sure you have adequate protective gear like eye and ear protection, a respirator mask, and rubber gloves to protect your skin against irritants.
How to prep wood for paint
A common mistake among new painters is to go straight to adding the first layer of paint to the wood. Wooden materials are a bit finicky, and if the wood is not properly prepped before painting, the paint will quickly separate from the wood and begin peeling off. To ensure a long life for your new coat of paint, prep your wood with the following steps.
Clean the surface of the wood
To ensure that your primer and paint bond well with the wooden material, clean the wood thoroughly with a TSP and water mixture. Be sure to allow adequate time for the wood to air dry to prevent paint blistering or even mold growth between paint coats.
Sand the surface of the wood
Sanding the wood surface creates tiny dings and scratches that allow the paint to bond well to the material. Using a handheld orbital sander for large, smooth surfaces or sandpaper strips for smaller, more ornate surfaces, sand the entire surface of the wood. Be sure also to sand the corners and ridges of your wooden piece.
Clean off dust and debris
Sanding creates a lot of wood particles and dust, which you won’t want to have on the surface when you apply primer or paint. These particles will create a bumpy and imperfect coat of paint. If you’re sanding a large surface, we recommend using a shop vac so that the particles are removed and contained instead of floating around the room.
Wipe the surface of the wood with a damp cloth to remove any remaining dust and debris.
Apply primer to the surface of the wood (second coat if still translucent)
Prime the surface of the wood using a paintbrush or roller, depending on the surface area’s size and the number of details in the piece. Allow the primer to dry thoroughly and apply a second coat if it still looks translucent.
Sand the primed surface
Again, since sanding helps paint to bond well to the wood material, sand the primed surface of the wood, and repeat the process of cleaning off dust and debris.
Apply the first coat of paint
You’re now in the home stretch! Grab your paintbrush or roller, depending on the size and ornate details on your wooden surface, and apply the first coat of paint. Be sure your brush strokes or paint rolls are with the grain for a more natural and smooth appearance.
Sand the painted surface
We feel like a broken record, but once the first coat of paint dries, you’ll need to sand the surface again before applying the second set of paint to ensure a beautifully bonded paint job.
Apply the second coat of paint
Repeat the painting process in the same way as you did for the first coat, and you’ll achieve a beautiful, evenly painted wooden surface.
Painting can be a fun or even relaxing pastime for many of us. While we all want to jump ahead to the fun part, it’s imperative that you faithfully complete all of the necessary steps in the preparation process before slapping on that coat of paint. Failing to do so could result in a less-perfect paint job, including peeling, blistering, or uneven paint coats. If that happens, you may have to scrape off the damaged paint and start from scratch. Avoid unnecessary headaches and prep for the job the right way.
