What Happens If You Don’t Sand Before Staining Wood?

For finished woods, you don’t need to sand the wood before staining only if you’re willing to use gel stain for staining. But you need to clean the surface well with a quality wood cleaning product.

But for bare woods, you should lightly sand the wood before staining. Otherwise, you won’t get a smooth surface without surface randomness and the wood stain won’t attach well to the bare wood without sanding.

First of all, let’s see how sanding helps with the staining process,

  • Sanding helps to open up the porous structures of wood surfaces and to make wood fibers absorb stains well
  • Sanding will eliminate surface bumps and randomness
  • Sanding will smoothen the surface for an even stain finish
  • Sanding helps to prevent of happening wood staining mistakes like blotches and patchy areas

This is why sanding is highly recommended light sanding before staining for bare woods.

But for the finished woods, the situation is totally different since they are already stained or finished by sanding and applying an evenly spread finisher all over the wood.

Therefore, it is not necessary to sand the finished wood since they already have a smooth surface with no randomness.

Since there’s no need for sanding, here you only have to think about what type of stain should you use.

Oil-based stains, water-based stains, or gel stains generally work so well with any wood to darken or color up the wood while enhancing the wood’s appearance.

But when it comes to finished woods, better to apply gel stain to darken the wood or remain the wood in the same color with no sanding.

Gel stain does not absorb into the wood fibers like oil-based and water-based stains. It sits on the wood surface and provides an even finish with an enhanced look.

Many of the gel stains usually darken the wood color. But some don’t change the wood color and increase the natural appearance of the wood.

So, let’s find out how to stain over wood without sanding to get a clear idea about how it should be done.

How To Stain Over Wood Without Sanding?

With gel stain, you don’t need to strip the existing finish on the wood. Even the bare woods don’t need to sand deep down if you’re willing to apply gel stain since sticks with any wood resulting even finish.

Please note that the below procedure is only applicable for finished surfaces with an existing finish. For bare woods, you need to do the sanding before staining.

So, let’s see how to stain over wood without sanding,

  • Lint-free tack cloth
  • Clean rags
  • Fine Grit sanding block for smooth finishes

Here’s the procedure for staining wood without sanding,

  1. Surface Preparation
  2. Clean the wood
  3. Sand the wood
  4. Apply Gel stain

1. Surface Preparation

First, you need to take your furniture or woodwork to a well-ventilated area for the staining project since you’ll have to deal with chemicals.

Or you can open the windows in your working area for good circulation.

Chemical fumes of Trisodium Phosphate (TSP) can cause skin and eye irritation upon deposition. Plus, wood stain chemicals upon application can cause breathing issues.

This is why staining in a well-ventilated area is important.

2. Clean The Wood

Cleaning is the essential step in most woodworking projects.

In this project, cleaning is a must because you won’t do sanding much before staining and dust collection pipes in your work area won’t be working since there’ll be no deposition of sawdust.

You’ll have to do the cleaning part manually with a lint-free tack cloth and clean rags.

Wipe down the finished wood surface to remove dust, debris, grease, dirt, and other residues.

Removing dust and dirt before staining is important because they can cause trouble when staining and once, they got trapped in the stain layer they’ll cause blotches and streaks.

Therefore, do the cleaning without missing any spots.

Once you’re done with dry cleaning with cloths, use TSP cleaner (Trisodium Phosphate) as a cleaning agent to remove dirt, grease, and other residues that are hard to remove simply by wiping with a tack cloth.

Wipe down the entire wooden surface with TSP cleaner without missing any spots.

Once you’re done with the cleaning part, let the wood dry completely before moving on to the next step.

3. Sand The Wood

Don’t get confused. Here we do not sand the wood entirely removing the existing finish. We just do light sanding over the existing finish to smoothen up the surface a little more.

The sanding block you need to choose depends on the roughness of your old finish,

  • If the existing finish is smooth

Take the Fine Grit sanding block and lightly sand the entire surface along the wood grain direction without damaging or scratching the old finish.

Light sanding the old finish will roughen it up a little bit to attach with the gel stain so well.

  • If the existing finish is rough or uneven

Grab the Medium Grit sanding block and lightly sand the entire surface along the wood grain direction and remove only the top layer of the old finish.

Make sure not to sand off completely the previous finish.

Light sanding the old finish will smoothen it up a little bit to attach with the gel stain so well.

This is how you should work with sanding blocks to smoothen up the previous old finish to make it ready to accept the new coat of stain.

Clean the whole surface by wiping it down with tack cloths to remove stain residue.

4. Apply Gel Stain

Now it’s time to apply the first coat of gel stain over the finished surface. Apply a thin coat of gel stain using a foam brush.

Apply gel stain along the direction of the wood grain for better absorption to the previous layer and to get an even finish with no troubles.

Apply gel stain over the finished surface by applying light and even pressure to the foam brush. Wrong gel stain application methods can form a thick layer of gel stain that can take so long to dry completely.

Therefore, always go for thin layers of coats for quick and efficient drying between coats.

After applying the first coat of gel stain let it dry for 72 hours and then apply the second coat of stain.

Apply 2 coats of gel stain to get the preferred color as you wish. Most of the time, gel stain gives dark color with additional coats. Apply more gel stain coats to get an even darker finish.

Or you can limit the number of coats and let the wood color remain the same throughout the process.

Let each coat of gel stain dry and cure well for at least 72 hours between coats. Never apply another stain coat before the previous one dries completely since that can result in never drying tacky surface.

Hot take: staining wood with gel stain is WAAAAY easier than polyshade

— bela lugosi’s dad (@markpopham) December 28, 2015

5. Seal Wood With Poly

Even though wood stain has the ability to protect the wood from environmental impacts while changing the wood color, the protection can easily break under harsh weather conditions.

This is where polyurethane (also means Poly) comes for help.

Polyurethane finishes are specially designed to protect wood surfaces from environmental elements such as moisture, UV light, rotting, decaying, and insect attacks.

Once the final coat of stain dried and cured completely, apply 5 to 6 coats of Wipe On Poly with Matte Finish to seal the surface.

Apply Poly using the same procedure that we applied for staining. Use a foam brush for the application, apply along the direction of the wood grain and let each coat dry well between coats.

Make sure to apply polyurethane correctly on the finished wood surface without making mistakes since we’re already in the final stage which is hard to go back.

Matte Finish Poly washes up the surface e nicely without making the surface too glossy.

Or you can use General Finishes High-Performance Topcoat instead of Poly to seal the wood with extra protection.

Can You Stain Varnished Wood Without Sanding?

Never stain varnished wood without sanding since the stain won’t attach well to the varnish coat. Better to apply the wood stain first and then apply varnish over the wood stain.

Wood stain prefers to stick on bare wood than sitting on an existing varnish finish.

Therefore, strip down the existing varnish layer and apply wood stain all over the surface along the direction of the wood grain and apply 3 to 4 coats of stain until you get the color you wished.

Then apply 3 to 4 coats of varnish to seal the stain finishing including wood. Doing the opposite is just a waste of time.

Can You Darken Stain Without Stripping?

Yes, you can darken the finished wood without stripping by applying a dark gel stain over the finished surface.

Apply 2 to 3 coats of gel stain on the finished surface to get a darker tone.

Applying more gel stain coats results in an even darker finish.

Let each coat dry and cure completely between coats and apply gel stain along the wood grain for an even finish.
