How to Get a Smooth Professional Paint Finish on Furniture

Learn how to get a smooth paint finish to give your DIY projects a professional look.

I know it’s been a couple weeks since I shared a remodel update or home improvement DIY. After getting the master bathroom vanity built and finished, I was a little tired. But now I am ready to get back to work. So today I am sharing with you a tutorial about how to get a smooth professional paint finish on furniture.

The master bathroom build was not a small project. In fact, it was my biggest build to date! I feel super accomplished at getting it done, and now I am ready to take on the world (or at least another big build project). 

This is exactly what I needed! If you spend time building a beautiful piece of furniture, you will need to know how to get a smooth professional paint finish on it. All the tips and techniques for you to DIY a high-end piece. | Housefulofhandmade.com

We have had the vanity in our master bathroom for a couple weeks now, and everyone that comes to visit must go check it out. It has been really awesome to see their reactions. I have heard “You really built this?” and “It looks professional not homemade.”

As much as I want to believe the comments are all about my skills with power tools, I know that the finish on the vanity is what is making people really impressed.

I hate to admit that some of my early building projects didn’t turn out as high-end looking as the bathroom vanity. Even my coffee station (which I still absolutely adore) is not as professional as the vanity.

But I have been learning a lot by trial and error over the last few years and I want to share this knowledge with you so you know how to get a smooth professional paint finish on furniture you build too.

Picking the Best Materials for Your Project

Before we get into the how to for the finish, I want to take a minute to talk about things that need to be done in the building process to make the painting step much easier!

I hate sanding and I hate painting! But I do it because no one will do it for me and I want to actually be able to use the pieces I build. So I always take a little extra time in the building to cut down on time spent finishing a piece, starting with the wood I choose. I know it is tempting to make pieces of furniture out of cheap 1x2s and 1x4s, and they definitely have a place in my wood shop.

In the beginning, I used them frequently so it didn’t cost a lot when I messed up. I built a toddler bed for less than $25 and this nautical picnic table for less than $50 because I used these inexpensive building materials.

But these woods are soft and will not hold up over time. So when I build with them I know that they will be pieces that are used for just a few years. 

However, using a harder wood will give you a more solid piece that will last for many, many year and the hardwood is much easier to achieve a smooth professional finish on.

Budget Friendly Hardwoods to Build With

Using hardwood can get expensive, but there is a more budget friendly alternatives like knotty alder and poplar.

I used knotty alder to make these rustic railings, this dining room hutch, and the master bathroom vanity (and all the supplies for our 8′ double vanity cost less than $350). It is really easy to work with, but be warned, there are quite a few knots in it. I personally love the knots because my house is full of rustic charm.

If you do not want the knots, you can always buy regular alder which is a bit more expensive but not as expensive as other hardwoods.

Poplar is a great option for painted furniture. It can have some uneven or greenish tones so if you are not painting, make sure to carefully pick out your boards to match. 

I used poplar for all the cabinet doors in our kitchen. Also for this stained TV stand. Poplar is easy to work with and has no knots. 

Next time you go the hardware store, go feel the difference between the hardwoods and pine or inexpensive lumber. You will notice how much smoother the surface is. And the boards are much straighter, all these things will ensure a high-end finish in your building project.

Now on to the painting and finishing!

How to Get a Smooth Paint Finish on Wood

Supplies:

  • Sandpaper, multiple grits from medium to ultra fine
  • Paint
    • I don’t believe there is one paint that is the end-all-be-all for the best results. Use what you love. I use the Behr Interior Paint & Primer in One most often and am very happy with the results. For the master bathroom vanity I used the Behr Pot of Cream in Eggshell.
  • Paint sprayer
    • A paint sprayer will give you the smoothest finish, but you can still achieve a great finish without it. Make sure to use a high quality paint brush. Thankfully there are budget friendly paint sprayer options now and I love my HomeRight Finish Max sprayer.
  • Vacuum
  • Tack cloth
  • Sanding sponges
  • Polyurethane, Polycrylic or Sealing wax protective finish

1- Prepare for Paint

Proper preparation is the key step to getting a smooth professional paint finish on anything! 

Start by sanding your piece very well. All the paint in the world cannot cover up rough wood. This is one of the main reasons I love using quality lumber, it makes sanding so much easier. If you are starting with rougher lumber, start with a medium grit sandpaper. Then step down to a fine grit and always end with an extra fine grit.

Sand in the direction of the grain, paying extra attention to the

Once the entire piece is sanded down, vacuum it to remove dust, debris, and sawdust. I do not have a shop vacuum so I use my household Dyson. If you have a dusting attachment, use it to help loosen anything on the surface of the wood.

After the surface of the wood is vacuumed and appears clean. Use a tack cloth to pick up the fine dust particles from the wood.

This is the first time I used a tack cloth and it is a game changer. It’s super easy to rub all over the furniture piece and it’s amazing how much dust you will get off what looked like a clean surface. This also helps you see if there are any spots that need additional sanding because the tack cloth will snag on a rough spot.

2- Paint the First Coat

Now you are finally ready to apply paint. I used the HomeRight FinishMax sprayer. Painting the vanity with the sprayer took a fraction of the time it would have taken with a paint brush. Also, it dried quickly so I could complete the project faster.

To use this paint sprayer you need to thin the paint (their new Super FinishMax sprayer does not require it). You can determine if your paints needs to be thinned by using a very simple drip test. The paint must pass through the specific container in 25-40 seconds to be ready to use in the sprayer.

For my first coat, since it would ultimately be my primer (my paint had primer included in it), I only thinned it to 40 seconds so it was the thickest it could be for more solid coverage.

If you are using a water based paint, you can thin it with just water (yay!). If you are using an oil based paint you will need to use an oil-based medium that is recommended by the paint you are using.

Completely cover the entire surface of your piece in paint. Be aware that it will be spotty/streaky as the paint will soak into the wood a bit. Do not apply a thicker coat for the first layer to try to achieve a smooth finish or you may get drips. Multiple coats are necessary and will result in a better final finish.

When to Paint Furniture

It’s worth noting that I painted my vanity in the summer, and it was HOT and DRY! We had temperatures in the 90s that week.

Typically, it is not recommended that you paint in extreme hot or cold temperatures. The paint will dry extremely fast in these high temperatures.

If you are using a paint brush to paint in the heat, it will leave brush strokes and the paint will dry in your brush making a mess of the brush and leaving clumps of paint or brush strokes on your furniture. This will not result in the smooth professional paint finish you are hoping for.

The paint sprayer did not have any issues in the heat though. And it was dry almost immediately after painting so that was an added bonus.

3- Paint the Remaining Coats

After the first coat has dried, you need to use a fine grit sandpaper and sand the entire surface by hand. I use the sanding sponges for this step and love them. They make it easier to get into corners because the sanding surface is on 4 sides of the sponge.

Sanding the first coat of paint with a sanding sponge to ensure a smooth paint finish on the wood.

Give it a good sanding by hand, but be careful around edges because it is easy to sand them too much and end up with a worn look (or go heavy on the edges for the much loved worn look). To make sure the piece is sanded enough, I run the palm of my hand over it to see if it feels smooth to the touch.

Once everything is sanded, pull out the vacuum again. Vacuum the entire piece of furniture as you did above. Then grab the tack cloth and remove any additional dust from the surface.

Vacuuming the sanding dust off between paint coats.

Now it is time for a second coat of paint. For the second (and third) coats of paint, I thinned the paint to a thinner consistency. For the drip test, it only took 25 seconds for my paint to pass through the container.

The thinner paint made for a smoother coverage from the paint sprayer. Coat the entire piece of furniture with a second coat of paint. There should be very little to no streaks/spottiness when you finish this coat.

After the second coat has dried, repeat the hand sanding, vacuuming and tack cloth as before.

Now it is time for a third coat. Thin the paint the same as you did for the second coat and cover the entire piece. After this coat the surface should look smooth and uniform.

I stopped at 3 coats for my bathroom vanity, but sometimes a forth coat is needed or desired. If you want a 4th coat, make sure to sand, vacuum and tack cloth the surface before adding it.

4- Add the Protective Finish

Once you are happy with your paint. Give it a very light hand sanding with the ultra fine sanding sponge. Then it is time to protect it.

Typically a higher the gloss to a finish, the easier it will be to clean. I usually use a satin/semigloss finish for walls and furniture in the kitchen and bath, but I really wanted a chalk finish to our master bathroom vanity so I decided to use a sealing wax on this piece instead. I am not sure how it will hold up to use in the bathroom, but if it ends up with a slightly worn look it will still fit in perfectly with my decor so I am not worried.

If you want more protection on your furniture, use a polycrylic or polyurethane protective coating. Be aware that polyurethane with yellow over time so it is not a good idea to use in on white or light colored paint. Use polycrylic for these lighter colored paints instead. 

If you are using a sealing wax, apply it with a paint brush and then wipe off the extra. Repeat if needed, but typically 1 coat is sufficient for waxes.

If you are using a poly coating, using a high quality paint brush or paint sprayer apply a coat to the entire piece of furniture. Let it dry.

If a second coat is needed (and I usually advise at least 2 coats for normal furniture and 3 coats for high traffic or areas around water), you will want to sand, vacuum and tack cloth the piece between coats. This will ensure a super smooth finish. However, you do not want to sand the final coat or you will end up with a cloudy finish.

Now you can stand back and admire your beautifully painted piece of furniture that no one will be able to tell was homemade!

Our entertainment center was finished with this process, including 3 coats of polyurethane and it still looks fantastic almost 10 years and 2 kids later. A proper paint finish will make all your pieces stand the test of time, and isn’t that what you want from a piece you spend the time to build yourself? I know I do. Maybe I’ll even be able to pass them down as family heirlooms someday.

It may seem like a lot of work for a perfect paint job, but it really is mostly waiting for things to dry. And if you want to take the time to build something you will want to finish it properly too.

Which Behr 2 in one primer and paint did you use? The Behr Ultra or the Premium Plus? I am getting ready to paint my unfinished pine bedroom furniture in white. Thanks Sue

I've used both. The more expensive paint tends to give you better coverage in less coats. But darker colors also coat better. I would recommend paying more for lighter colors, you can choose of its worth it for darker ones. Hope this helps!
