The Secret To Removing Wood Grain On Oak Cabinets (2024 Review & Video)

Aqua coat Grain FIller Tutorial

For a super-smooth, professional finish, I’ll show you the best wood grain filler for oak cabinets and the easiest way to apply it!

---

Nothing can transform a kitchen like painting old oak cabinets.  But don’t miss out on a smooth grain-free finish by skipping the most important step – using a wood grain filler!

Honey oak cabinets were fine for the ’80s but their orange hue and busy grain pattern are an eyesore when it comes to today’s kitchen trends. 

But covering that stained oak with paint doesn’t necessarily solve all your problems!  Unfortunately, certain wood species like oak wood have a very open grain.  That means the grain makes deep divots in the wood that, even when painted, can show up as distracting little pock marks in your paint finish.

Fortunately, I have an easy solution to fill in the deep grain of oak cabinets that will leave your paint finish smooth and flawless!  This step-by-step DIY tutorial will show you how to use the best wood grain filler to get a professional look on oak cabinets.

 

LET ME SHOW YOU:

How Do You Get a Smooth Finish on Oak CABINETS?

Using the right paint and primer is important but using a good wood grain filler will give you the smoothest finish when painting oak cabinets. (See my full tutorial on painting oak cabinets from start to finish by CLICKING HERE.)

Is wood grain filler necessary?

No one wants to add a step to their cabinet refinishing project but using a good grain filler will make such a dramatic difference in the look and texture of your cabinets that is it worthwhile.  Also, you will use less paint and primer and the grain filler not only evens out the surface but provides some coverage.

Paint color also determines how much you will be able to see the grain of the painted wood. Lighter colors show grain more than dark colors.

Why A Wood Grain Filler Was Worth It

Cabinet painting isn’t easy. It’s a long process with several steps that creates a mess in the most important room in your home. And adding Aquacoat is yet another step in the process.

Since repainting my own cabinets, I feel like Aqua Coat was the key to my DIY project not looking like a DIY project. Even though I did everything myself, I still wanted a professional finish and for my oak cabinets, a grain filler was the key!

So, yes, it adds a big step to a project that is a lot of work but if you are going to the trouble of painting your cabinets, you want them to look amazing and the finish to last a long time! The good news is that Aquacoat gave me the professional finish I was looking for.

Here’s one of my cabinet doors painted without grain filler:

Here is the same door on my kitchen island with grain filler. I took the picture with a glare so you can see the surface better. You can still see a little of the grain and I don’t mind that. I still wanted the cabinets to look like hardwood and not laminate. But you can definitely see all the grain indentions were filled in and the finish is much smoother.

If you want a COMPLETELY smooth finish with Aquacoat, I show you how to do that below.

Does primer fill in wood grain?

Some primers do a better job of filling in the grain of the wood than others.  For example, the two primers I used most are Zinnser BIN and Zinnser Cover Stain.  Because Cover Stain is thicker and has a bulkier texture that sands really well, I recommend it to help fill in deep wood grain. Although a primer helps, it’s not nearly as effective as a paste wood filler made for filling grain.

Is there a paint that fills wood grain?

Some paints are better than others when filling wood grain.  After testing over 24 paints for cabinets, I found that Benjamin Moore Advance came out on top:  The Best Paint for Cabinets (24 Paints Reviewed & Blind Tested)

I wish I would have known about Advance when I painted the wood cabinets in our old house. But even as great as Benjamin Moore Advance is at helping to fill the grain, nothing is more effective than a grain filler that is specialized for filling wood grain over large surfaces.

Using the right grain filler will make the biggest impact on making sure that your cabinets are smooth but using the right paint and primer will help that much more.  That’s why I include all the best products in this tutorial.

Is grain filler the same as wood filler?

Standard wood filler is usually for filling large holes, nail holes, or damage on furniture.  But a wood grain filler is specifically for filling pores of open-grained woods.  There’s also stainable wood filler that contains real wood fibers and is specifically for filling holes in bare wood that will be stained.  Bondo wood putty is often used to fix damaged furniture where a durable hold is needed.  What you really need is a wood poor filler.

What’s the Best Wood Grain Filler for Oak Cabinets?

After trying and comparing several products, the absolute best wood grain filler for oak cabinets is Aquacoat grain filler in white.  Below I’ll share about the different options and why they don’t measure up to give you a smooth finish over a deep wood grain Aquacoat.

5 Options to Fill Wood Grain in Oak Cabinets:

Joint Compound – Several professional painters use joint compound to fill the small holes in oak wood.  However, when it comes time to wipe off the sanding dust, the dried joint compound can easily wipe out of the woodgrain.  In other words, it fills well but doesn’t adhere to the surface of the wood as well as Aquacoat.

Bondo Wood Grain Filler for Oak Cabinets – Bondo is a good product but it has to be mixed to the right consistency and getting it too thin can mean extra coats.

Crystalac Clear Wood Grain Filler – Clear grain fillers don’t have the substrates needed to settle into wood grain because they have to remain clear.  Clear grain fillers are the best grain filler for guitars and other stained wood. However, they aren’t thick enough as a wood filler for cabinets.  Aquacoat grain filler in white also helps to provide extra coverage so you use less paint.

Drydex Grain Filler for Wood – Several professionals use Drydex as a wood filler for cabinets. Since Drydex is created for walls and not wood cabinets, it will eventually fall out of the grain over time. One professional told me that Dry-dex has the tendency to cause flashing to the finished cabinet surface. The same applies for Famo Wood Filler.

Aquacoat Grain filler for Wood cabinets

Aqua Coat’s pore and grain fillers penetrate and seal the pores of the wood, minimizing the absorption of your topcoats or paint, or primer.    They are ideal for filling the grain on oak cabinets to provide a smooth and beautiful finish. CLICK HERE TO SEE MORE REVIEWS AND THE CURRENT PRICE.

Aqua Coat is the lead producer of wood grain fillers and their products are environmentally friendly, safe for use (non-Flammable and non-Combustible), low odor, low VOC, and designed to dry fast. It also sands easily, and you can use water cleanup for quick and easy application for filling oak grain.

Aquacoat is the best grain filler for wood because it has the least amount of shrinkage, it adheres well to the pores of the wood, and its thin paste consistency makes it incredibly easy to work with.  Since Aquacoat is a paste filler and thinner than traditional wood grain fillers and the consistency is that of thin toothpaste.

There are a couple of different types of Aquacoat.  Be sure to get the white grain filler as opposed to Aquacoat clear grain filler.  You can see the current price of the white filler here: Aquacoat White Grain Filler

Supplies Needed: How To Fill Wood Grain in Oak Cabinets

where to buy Aquacoat, The Best Wood Grain FIller

I have looked for Aquacoat Grain Filler at Home Depot and Lowe’s with no success.  Fortunately, you can find it at a good price on Amazon here:  See the Current Price of Aquacoat Grain Filler

Aquacoat is pricier than some of the other grain filler options but this is one of those instances where you get what you pay for (and so much more!)  Do NOT skimp and get another grain filler because it could mean having to completely redo your cabinets if the grain filler doesn’t adhere to the pores well.

Fill Any Old Hardware Holes First (How Do You Use Wood Filler on Cabinets?)

Before we get started, you want to go ahead and fill any old hardware holes but for this, you’ll use standard wood filler.  Here is everything you need to know for that step:

The Best Wood Filler for Screw Holes  | The Easy Way to Fill Hardware Holes |  The Ultimate Guide to Fix Damaged Wood and Furniture

How Do You Use Aquacoat Grain Filler?

I did the whole process below from start to finish on my cabinet boxes first.  Then, I did the process on my doors and drawer covers.  This made it less overwhelming and works better for Aqua Coat’s dry time.

Be sure to follow along with the video as you go through the tutorial.  The video better illustrates how to apply the grain filler to best fill the pores of your cabinet doors, drawers, and boxes. If the video isn’t showing up, you can also find it here: How to Use Aquacoat Grain Filler on Oak Cabinets, YouTube Video

Step 1: SAND The Cabinets

Be sure to check out my post on installing hardware to find out why I like to drill my new hardware holes first: The Easy Way to Install Cabinet Hardware

Sand with your electric sander or a block of 220 sandpaper.  This is to rough up the entire surface so it better accepts the Aqua coat and it adheres well. 

I love my Black and Decker Sander. Its so easy to use and if you aren’t familiar with using one you check out this post: How to Sand Furniture in Less Than 5 Minutes

Also, I use these sanding pads that are slightly bigger so that it’s easy to sand in the grooves with the edge of the sander. I used the 240 for this step but you’ll use the other grits later in the project.

Do you need to sand before using Aquacoat?

Yes, but you are not sanding off the old finish, just roughing it up.  You can see in the video that this doesn’t take long at all!

Step 2:  Degrease

I chose to degrease my cabinets after sanding in order to combine two steps.  By wiping down the cabinets you are cleaning them and also wiping off the sanding dust.  Even though we already sanded the surface, we want to degrease the wood’s surface including any oils that may have penetrated the surface.

I like to use Krud Kutter or degreasing cabinets.  Simply spray it on and scrub with the green side of a sponge.  Then, wipe off the surface with a damp rag to remove excess degreaser.

Step 3: How to Fill Oak Grain Before Painting Cabinets

Now is the fun part!  Put on your disposable gloves and wet a roll of paper towels.  You also want to cover your workspace.  Sometimes I’ll use kitchen garbage bags and just use them for trash as normal after I’m done with applying the grain filler

IMPORTANT NOTE:  I used grain filler on my cabinet boxes and the fronts of my cabinet doors and drawers.  I did not use the grain filler on the backs of the doors because it’s just not worth it, in my opinion.

I like to work in the center of the door first.  Take a generous glob of Aqua Coat in your hand and wipe in a circular motion.  This is to help work the grain filler into the pores of the wood.  It’s pretty cool to see how there are whole sections of the wood surface that the Aquacoat fills in that were lower than the rest of the surface.

Now, I will wipe the excess filler off the center panel with a spreader.  You’ll want to run the spreader over the wood in the opposite direction of the grain.  Put the excess back in the Aquacoat container.  You will be wiping off a lot more excess than what actually fills the grain, so that’s why it’s important to save the excess.

Notice how you still see a bit of the wood showing but the Aquacoat has nicely filled in the grooves, grain, and pores.

After spreading grain filler on the center panel, I like to use my index finger to remove more excess on the edge.  You will have some ridges of grain filler left after you’ve removed the excess and that’s completely fine – we will sand those down after it dries.

Using the same circular motion, wipe the grain filler into the groove.  Use a spreader or a damp paper towel to very lightly remove the excess.

Pay attention to the corners especially to make sure that grain filler doesn’t settle in those areas.

Finally, apply the Aqua Coat in the same way to the frame of the cabinet door. You can lightly wipe off any excess with the paper towel again.

After you have added wood grain filler to every part and also removed the excess, do one last check.  Make sure it’s as smooth as possible and that wood filler hasn’t settled into the corners.  If it has, wipe it out with your finger so it doesn’t dry in place.  You can better see how I did this in the video.

Step 4:  Let The AquaCoat Dry

Let the Aquacoat dry for 2 hours.  Soon after that window, you will want to go ahead and sand so you can get primer on.    

Does Aquacoat Shrink?

Getting a coat of primer on soon after the dry time will help to ensure there is no shrinkage.  All products of this nature can shrink and Aqua Coat shrinks the least but we still want to minimize it as much as possible.

IMPORTANT TIP:  When I was working on my doors, I split all of my doors into 3 different groups.  I did the full process for each group before starting the next.  This is not a must but it helped to minimize the time before applying primer.

The instructions say you can add additional coats of Aquacoat to get a perfectly smooth finish but to me, it just wasn’t worth it.  I wanted to fill the pores of the grain but if you could still see a little of the grain’s texture, I was ok with that.  Also, I didn’t want the surface to look so smooth that the cabinets looked like they were laminate.

How Do You Get A SUPER Smooth Surface on Wood?

If you do want a COMPLETELY smooth surface, you’ll want to add a coat or two more of grain filler as you might have noticed on the Aqua Coat grain filler instructions.  If you want a really smooth surface but can still tell that it’s wood, you only need 1 coat.  The primer and paint we are using help with smoothing the surface as well.

Step 5:  Final Sanding

Once the surface of your cabinet doors or boxes has dried, you will lightly sand off the excess with a 320 sanding pad on your electric sander.  Sand very lightly to remove those ridges or anywhere the grain filler isn’t completely smooth.  You can use a sanding block for the inside of the grooves.

Sand until the surface is just smooth and then don’t sand anymore past that.  I wouldn’t use an orbital sander for this step because it might sand the filler out of the grain but an electric sander is fine.

Step 6:  Wipe The Cabinet Doors and Boxes

Now, wipe your door down with a damp cloth or paper towel to remove any sanding dust.  I used a chalk paint brush to brush the dust out of the corners but any paintbrush will work.  This is probably the only time I’ll ever use a chalk paintbrush.

Step 7:  How Do you Prime Oak Cabinets?

As soon as you have sanded and wiped the wood’s surface, you want to get a coat of primer on the wood to prevent shrinkage.   The primer almost acts as a top coating or sealer for the grain.

I like to use a brush and roller to prime and paint my Alabaster white cabinets and you can see exactly how to prime cabinets here:  How to Prime and Paint Oak Cabinets For a Smooth Finish

I chose Zinnser Cover Stain as the primer for my cabinets because the sandable texture is more conducive to filling in wood grain. 

Step 8: Paint Your Cabinets

I like to use two coats of primer and two coats of paint.  I’ll detail every detail of getting a professional finish on cabinets easily in my next post:  How To Get a Smooth Finish On Oak Cabinets (COMING SOON)

Can you paint aqua coat grain filler?

Aqua coat grain filler is in white is paintable but the clear formula is not.  Make sure you get the white Aqua coat for cabinets and furniture here.

Can you put Aqua Coat over paint?  Should I prime before wood filler?

Their website says you can put Aqua Coat on after priming and painting as long as you apply and sand before your last coat of paint.  I recommend using it before priming and painting your cabinets.

Do you stain before grain filler?  Is Aqua Coat Stainable?

The clear Aqua coat is for stained wood and the white is for painted wood.  When using the clear Aqua coat, you should stain the raw wood first, let it dry completely, and then apply the clear filler. 

What is Aqua Coat made of?      

Aqua Coat is the lead producer of wood grain fillers and their products are environmentally friendly, safe for use (Non-Flammable and Non-Combustible), low odor, low VOC, and designed to dry fast, and sand easily with water cleanup.  For more information, check out their website here:  Aqua Coat

Not only is Aqua coat the grain filler that will give you the best results but it’s super easy to work with.  It has a thinner texture than traditional grain filler without being drippy.

What paint finish shows wood grain less? 

Now that you no longer have that high gloss finish of your orange oak cabinets, you can still lessen the subtle appearance of any remaining grain by using the right sheen.  Satin sheen is less shiny than semi-gloss and is still durable enough for cabinets.

How can I update my oak cabinets without painting them?

If you want to bypass all the work of painting your cabinets you can try changing them to a darker, not-so-orange tone with gel stain.  You can use this exact same process to get a darker tone on your cabinets:  How to Gel Stain Wood
