If you are a fan of fast and easy painting without leaving any brush strokes on your furniture, spray painting is the way to go. But first, you need to learn how to spray paint furniture with a spray gun.

Steps to Spray paint furniture With A Spray Gun
Step 1: Safety and furniture prep
It goes without saying, whenever you have a painting job to do or any woodworking project to carry out, you must ensure adequate ventilation in your workstation.
Next, ensure you have a respirator mask, some disposable gloves, and goggles for your eyes. You can even go the extra mile and wear a coverall. (If you’re unlucky to inhale the fumes, follow our guide on how to clear lungs of spray paint for quick remedy).
The next step is to seal off anything and every part of your workstation from catching paint over-spray. To do this, you will need a painter’s plastic.
You should tape down the painter’s plastic to ensure that it doesn’t get blown around.
An excellent alternative to the painter’s plastic is the Wagner pop-up tent. Once you set it up, you’re almost good to go.
Prepare your furniture
First, clean your wood furniture with a soft sponge and mild soapy water to eliminate dirt or grime. Then wipe the surface dry with a dry rag.
Next, fill the cracks (if any) with wood filler. Once the wood filler completely dries up, proceed to the next step.
Use fine-grit sandpaper (180-220) for light sanding your piece of wood furniture following the wood grain. Also, smooth down the excess filler. You can use sandpaper with a sanding block or a power sander at your disposal. Sand lightly along the wood grain
Wipe the sanding dust off your wood furniture piece using a tack cloth, and then use a shop vac to collect every pile of loose dust from the surface.
If you are working on chairs with padded seats, you should begin by removing the padded parts. If you can’t, do your best to seal them from catching the paint spray.
Also, if your wood furniture has any delicate vintage hardware on them -such as handles, hinges, and knobs- it’s best to unscrew them and put them in a separate container. This ensures they don’t get in the way of your painting.
But, should you find them challenging to remove or you just don’t want to go that mile, then seal them off using a painter’s tape or any masking tape available.
Step 2: Paint and spray gun set up
The choice of spray paint colors for wood furniture and spray paint type is determined by how much traffic your furniture gets. For example, water-based latex paint and chalk paint are best suited for dressers or furniture that doesn’t get much use.
Use oil-based paint for furniture that gets heavy use, such as dining or coffee tables. These paints will shield your wood furniture against paint chips, dents, and water damage.
You can confirm if your spray paint is waterproof if you intend to paint outside.
Open your paint can and give it a swirl using a craft stick or a clean stick to loosen any paint lumps. Next, strain the paint through a paint strainer into a clean container to eliminate any impurities that could ruin a smooth finish.
Thin your paint with about 10% water for water-based paints and paint thinner for oil-based paints. Mix well until you have the right consistency. In any case, check with the manufacturer’s manual for specific instructions on thinning paint.
Spray gun set up
Different spray guns are set up differently. A user manual is a great explainer, have it next to you for reference when you’re in doubt.
In this guide, however, we’re using a Flexio Wagner paint sprayer. This is a High Volume Low Pressure(HVLP) spray gun. So, first, assemble the parts of the paint sprayer.
The front part of the gun is the detail nozzle: it could be yellow or black. It can be rotated vertically, horizontally, and even diagonally for different spray patterns.
Rotate the tip of the nozzle vertically for a horizontal spray pattern. For a vertical spray pattern, turn the tips horizontally. Finally, turn the nozzle diagonally for a diagonal spray pattern.
Next, twist and align the “unlock” arrow with the handle on the paint sprayer. Then, insert and twist the spray gun against the spray gun handle to lock it tightly. The tab under the trigger will lock the two pieces together.
Next, insert the air hose tightly into the connection on the spray handle, and attach the other end of the sprayer air hose into the air compressor turbine. This is where the air pressure that pushes paint out of the paint cup comes from.
The knob behind the spray handle controls how much paint flows from the paint canister. Begin with a low flow dial set if the spray material is thin and vice versa.
Too high paint flow setting gives too much spray material and ends up with runs and sags on the surface. In contrast, too low a flow setting will give an inconsistent spray pattern without full coverage caused by too little material.
Test spray your paint sprayer with plain water first. This allows you to experiment with the different spray patterns and material control settings. Only test spray with actual paint once you are comfortable using the paint sprayer.
You can paint a cardboard box, scrap piece of wood to test the spray.
Step 3: Priming furniture
A primer helps bind the paint in place for longer. Most paints contain a primer in them. But, applying a thin coat of a bonding primer never hurts.
You may want to apply a stain-blocking primer to your wood furniture that hasn’t been painted before. This will ensure the wood tannins and odor don’t seep through the paint surface and cause unpleasant discoloration.
Use a water-based primer if you plan on using water-based paint or an oil-based primer to go along with oil-based paint.
You can apply the primer to your furniture pieces using a paintbrush or a foam roller. You can as well use a HVLP gun to apply primer. The goal is to have a smooth professional finish.
First, unscrew the spray gun’s paint canister. Next, pour the primmer into the paint cup until it is 2/3 full. Finally, screw back the cup and lock it tightly onto the spray gun.
Spray paint wood furniture while holding the spray gun at about 6 inches away. Ensure your wrist stays steady when you make the spray passes: if you tilt or turn it, you will end up creating an arc.
Press the trigger down to release the primer. Spray the primer in long passes from one end to the other. Release the trigger once the spray gun tip gets slightly past the other edge of the furniture.
Go over the entire furniture with the primer and only overlap between 30 to 50 % to ensure complete coverage.
Remember to smooth out any bumps from the primer application after the primer dries completely. Use fine sandpaper and sand along the wood grain. Use a tack cloth to remove every bit of sanding dust.
Rinsing the Paint Sprayer
Once the entire furniture is primed to satisfaction, it’s time to rinse your sprayer in preparation for the actual painting job.
For our Wagner sprayer, separate the paint gun’s nozzle, paint filter, and paint cup for easy cleaning. Use plenty of water and soap to clean water-based primer or paint thinner to clean oil-based primer.
Put the solvent type relevant to the primer or paint type you used into the paint sprayer paint cup. Then, spray the solvent to clean the lines of the sprayer thoroughly. Spray until there’s no more paint color left in the sprayer.
Allow the parts of the spray gun to dry thoroughly. Kindly refer to your paint gun’s manual for detailed and specific instructions on cleaning your spray gun.
Step 4: Spray painting
If you choose to apply a primer using a paint gun, the paint spraying technique is the same. However, pay attention to the following tips.
Spray the first coat of paint in thin coats. Then, allow it to dry fully for as long as the paint container recommends: about 1 hour for water-based paints and up to 4 hours for oil-based paints.
Lightly sand down every imperfection using fine-grit sandpaper (800). Then, wipe the dust using a tack cloth.
Spray a thick paint coat on the second coat for a durable flawless finish. Let it dry, and sand it before applying the third coat if you find it necessary.
Maintain the same distance (6 inches) away from your furniture for a consistent professional finish.
Once you pull down the gun’s trigger, keep your arms moving at a steady pace from one end of the furniture to the other. If you pause or slow down on the spot, you’ll end up spraying too much paint and cause it to run.
Occasionally, use a damp cloth to wipe clogged paint on the nozzle tip.

Step 5: Finish your project
Sand the topcoat to smooth out any bubbles or lumps on the painted furniture. Decide on the finish sealer you will use to protect furniture.
The most common way to finish your furniture is by painting polyurethane or a clear coat of wax. You can spray water-based polyurethane such as polyacrylic on your furniture following the spraying procedure above.
If you choose to apply wax, use a lint-free cloth to spread it evenly on the painted surface, especially if you chose chalk paint for your furniture.
