Why Is It Important To Sand Your Furniture Before You Apply Paint?

When working with wood projects, it is better to be cautious than sorry, especially when refinishing or sanding your valuable wooden furniture.

Before you paint your surface, it is important to prepare it by doing the sanding job so the paint can properly adhere to the wooden surfaces. Paint can’t adhere well on worn or slick wooden surfaces.

When preparing wood pieces for paint, the goal is to make the surface slightly rough to let the paint stick. If you distribute the paint while the furniture has a shiny surface, it will not be able to stick.

If you don’t sand your surface, you will risk wasting time painting the furniture since it will eventually fall off. That’s why you need to sand the surface lightly, so you don’t need to waste your time doing the same work all over again.

Preparing your wood surface before you paint it is one of the core steps to achieving success on this woodworking project. Moreover, it also will give a long-lasting good appearance on the painted wooden surface.

Furniture Sanding Instructions

  1. The First Thing To Do Is To Wear Your Protective Equipment

Safety is the number one priority! Always wear protective equipment when working on any woodworking project. Start by wearing a protective face mask and a pair of goggles.

Don’t let yourself inhale the small particles from sanding and getting dust into your eyes. That is the reason you need to wear those two safety tools.

  1. The next Thing Is To Use Wood Filler To Seal Up Any Dents, Gouges, Or Cracks

If your wooden furniture has no flaws, you can skip this step, however, if it has any gouges, cracks, or dents. Then you need to make smooth them out. Use a wood sealer to fill them up before you begin the sanding process.

Ensure you add adequate wood sealer and slightly keep the level above the wood surface. You can flatten it out with the rest of your wood surface during the sanding process.

Allow the wood filler to dry for about 48 hours before you can go to the next step. Refer to the wood filler product to learn how long you should wait for it to dry.

Following the wood instructions, a filler product is recommended to achieve optimal results.

  1. Use A Coarse Sanding Pad For Sanding

Now you can begin the sanding job. Begin with a sanding pad with 60 – 100 grit on an orbital sander.

Other than using an orbital sander. Depending on the wood’s condition and preference, you can also sand using an electric sander with medium grit sandpaper.

For example, you can finish the sanding job nicely using sandpaper with 120 grit.

Alternatively, you could sand with medium sandpaper grit without using an electric sander. You can do this job, but it can take longer than other methods.

If you prefer manual sanding, you can use a hand-held sanding block to get a better grip. You also want to ensure that the sandpaper attached to a foam achieves maximum flexibility when you sand curves.

The first sanding will scrape off the old wood finish with other irregularities in your wood. If you use a wood filler, this part will make the rest of your wood surface even.

For your information, sandpapers or sanding pads have lower grit numbers. The higher the grit number, the smoother the sanding pads will be, and vice versa.

When doing the first sanding, use circular motions and keep the pressure gentle and light. Be careful not to sand too deep. Make sure you sand the entire surface before changing to smoother sandpaper.

  1. Use A Finer Sandpaper For Sanding

Now, change the sandpaper into a smoother one after sanding your entire wood surface using a coarse sanding pad. For this part, you could use 240 or 320-grit sandpaper.

This job aims to make the surface turns smooth. You need to light sand using the new pad that covers your entire wood surface.

Do this until the surface turns smooth when you touch it. Moreover, you also need to sand according to wood grain to prevent marks on wood from being created.

The rules also apply if you decide not to use an orbital sander. You just need to change the sandpaper grit to a higher one. The recommended sanding block grit is 240 to 320 grit.

It will be much, much better to use a power sander. Not only will it let you be able to sand faster, but it will also be easier.

The sanding equipment is usually equipped with a dust collector to suck up sanding dust. This means that you don’t need to worry about dust after you are done sanding.

  1. Clean The Residues Using A Tack Cloth and A Damp Rag

Wipe the whole sanded surface using a tack cloth to clean up dirt and dust bump from your wood furniture.

Do I Need To Sand My Furniture If I Use A Primer?

The answer is no! It is unnecessary to sand your furniture if the surface is not peeling off or chipping. All you need to do is to clean it with a clean rag dampened with soap and water, rinse it and leave it to dry.

What Happens If You Don’t Sand Furniture Before Painting?

If you don’t sand your slick or damaged furniture’s surface before painting, the paint will eventually peel off.

This is because the paint needs something to stick, and a smooth surface doesn’t provide a medium for your paint to grab on.

If you attempt to paint on a chipping or worn finish without sanding, the paint will start to chip off. This can happen soon after you are done painting.
