Glazing with Acrylic Paint: Step-by-Step Technique for Miniatures 🎨

Let's get to it, makers! If you've ever been blown away by a miniature with such smooth color gradients they seemed like pure magic, you were probably looking at the acrylic paint glazing technique. It's what we in the hobby world call glazing.

This is one of those secrets that, once you master it, makes your printed pieces stop looking like a chunk of painted plastic and turn into a genuine work of art. And don't worry, I've got you covered today: I'm going to guide you step by step so you can master it. Let's go!

What exactly is a glaze and why is it going to change your minis forever?

To put it simply, a glaze is nothing more than a super diluted, transparent layer of acrylic paint applied over a color that's already dry. The idea isn't to cover what's underneath, but to tint it — like putting an Instagram filter on your figure, but with total control and done by hand.

The key to glazing is transparency. By building up these ultra-thin layers, we gradually shift the tone of the base without losing any detail. This is pure gold for pieces coming off our printers, especially when using a high-definition resin that captures an insane level of detail.

But what does this actually look like in practice? After many hours with a brush in hand, these are the uses that truly make a before-and-after difference:

• Creating seamless color transitions: This is the star application. It lets you blend two colors gradually, saying goodbye to those ugly jumps between highlights and shadows. The result is a gradient that looks natural and incredibly realistic.
• Unifying tones and fixing mistakes: We've all been there — highlights that ended up looking way too harsh. A soft glaze with the mid-tone right at the transition fixes it, blending everything together beautifully.
• Boosting a color or shifting it slightly: Is that red not intense enough? Want a blue to lean a little more greenish? A glaze of the color you want over the top and you're done. No need to repaint the whole area.
• Adding incredible color richness: Try glazing with colors that seem completely out of place at first glance (like a purple in skin shadows or a blue on steel). You'll see what an incredible visual depth you can achieve. It's something a regular coat of paint simply can't match.

For me, mastering glazes is what separates a good painter from a spectacular one. It's not just that the finish looks better — it gives you amazing creative freedom to play with colors and nuances.

It's true that it's a technique that demands patience, since it's built around layering color with many thin coats. But I can assure you the result is so stunning that once you try it, you won't want to paint any other way.

Glaze, wash, and layer coat: no more confusion — here are the differences

Okay, hold on. This is the point where 90% of people get completely mixed up. Seriously, I've seen countless makers confuse a glaze with a wash or a base layer (layer). The result? Pure frustration because the piece looks nothing like what they had in mind.

So that doesn't happen to you, I'm going to break down the differences exactly the way I would have loved someone to explain them to me when I started out in this hobby. Let's get into it!

The holy trinity of mini painting

Imagine your toolbox has a hammer, a screwdriver and sandpaper. Each one is for a specific job, right? Trying to drive a screw with a hammer... yeah, that's not going to work. With paint it's exactly the same.

• The Layer: Think of it as the big brush. Its only goal is to cover the surface with a solid, opaque colour. It's like painting a wall; you want the colour to be uniform and completely hide what's underneath. The paint comes almost straight from the pot, at a medium consistency.

• The Wash: This is the shadow specialist. It's super-liquid paint, almost like ink. Its job is to seep into every nook and cranny of the miniature thanks to capillary action. As it dries, it darkens those areas and creates depth and definition in a flash. Control here is minimal; you let physics do almost all the work.

• The Glaze: And here comes the crown jewel, the painter's scalpel. It's an ultra-thin, super-diluted and translucent layer of paint. The big difference from a wash is that here you have total control over where you put it. It's not about flooding the figure, but about subtly tinting the colour that's already underneath. It's the key to creating smooth colour transitions, unifying tones or slightly shifting a hue.

To make it crystal clear: the layer covers, the wash dirties to shade and the glaze tints with precision. These are three tools with completely different purposes.

To make this stick with you for good, I've put together a comparison table. Save it, print it out or tattoo it on yourself if you have to — just keep it handy at all times!

Technique comparison: Glaze vs. Wash vs. Layer

Understanding when to use each of these techniques is what will catapult the quality of your pieces to the next level.

For example, a typical workflow would be: apply a base coat, add a wash to define all the shadows, rebuild the highlights with more layers and, to finish, use acrylic paint glazes to unify everything and achieve that professional finish we're all after.

The survival kit for your first glazes

Let's get to it! Before diving headfirst into glazes, you need to set the stage. And no, you don't need to build a NASA lab at home. With a few well-chosen items, you'll have everything you need to start getting amazing results.

I'm going to share my shopping list — the things that are always on my work table.

The paint and the famous Medium

First, the obvious: the paint. Look for acrylics that are well loaded with pigment. Why? Because when you thin them down to make the glaze, you don't want them turning into a watery, colourless mess. They need to hold their intensity. Personally, I rely heavily on Vallejo acrylic paints — they're a safe bet for their quality and the incredible range of colours they offer.

Now comes the secret ingredient, the key to all of this: the glazing medium. I'm sure you've thought about just using water and calling it a day, right? Well, don't even think about it! Water alone can cause real trouble by breaking the paint's surface tension. The result is those horrible tide marks that ruin any paintjob.

To avoid any drama, the Vallejo Glaze Medium is my best friend in the workshop. This liquid keeps the paint behaving as it should, makes it flow better and guarantees a transparent, even coat. In my experience, it's the difference between a pro finish and a "better strip it and start over".

The brushes and your new best friend: the wet palette

Take note — not just any brush will do. For glazes you need brushes with a fine tip as sharp as a needle for precision, but that also have a good "belly" to hold paint without it dripping everywhere. Get yourself a good set of glazing brushes and they'll last forever if you look after them. I almost always get by with a size 1 or 2.

And finally, the wet palette. I'm telling you now: it's going to be your new best friend. Glaze mixes are very fluid and dry faster than you can blink on a regular palette. With the wet palette, your mix stays perfect throughout the entire session, and you can forget about preparing it again every five minutes.

So there you have it: good paints, a decent medium, the right brushes and a wet palette. With that combo, you're more than ready to master glazes. In my store you'll find all these mediums and auxiliaries that are going to change the game for you. Give them a look!

My glazing technique: step by step with the ratios that never fail

Right, enough theory. Let's get to what really matters: getting your hands dirty. I'm going to walk you through my exact process for applying acrylic paint glazes, sharing the ratios I use that, after plenty of trial and error, I know work every time.

Forget the second-guessing and the strange mixes. I'm going to hand it all to you on a plate so you can just get on with painting.

My goal is that, by the time you finish reading this, you'll grab your brushes and dive right in without any fear. You'll see that, with a bit of structure, it's much easier than it looks.

Step 1: The magic potion on your wet palette

The first thing is to prepare our mix. There's no universal formula that works for everything, because each paint has its own opacity, but there is a starting point that almost never lets me down.

• The ratio to start with: Try 1 part paint to about 4 to 10 parts of glazing medium.
• A touch of water: If you notice the mix is still a little thick, don't hesitate and add 1 or 2 drops of water to help it flow better. But be careful — we don't want soup!

My golden tip: always start at the lower end of the dilution (1:4) and do a quick test on a piece of plastic or in a corner of the palette itself. Can you see it's covering too much? Then add more medium. We're looking for a consistency similar to skimmed milk: fluid, but without being simply water with a hint of colour.

Trust me, the wet palette is your best friend for this. It lets you play around with the ratios at your own pace and keeps the mix perfect for hours. On a dry palette, it would be an absolute nightmare.

Step 2: The brush trick: loading and unloading is the key

This is the technique that separates a smooth, elegant glaze from a disaster full of tide marks. It's not just about dipping the brush and going. The secret lies in control.

First, load the brush by dipping the bristles into your glaze, but try not to let it reach the ferrule (the metal part — if it fills up with paint it will end up ruining the brush).

Now comes the key move: unload the excess. Gently run the brush over a piece of kitchen paper or even the back of your hand. The goal is to remove almost all the moisture, leaving the bristles impregnated with pigment, but not soaked. You'll know you've got it right when, as you run the brush over the paper, it leaves a translucent mark rather than a puddle.

If you skip this step, you're going to flood the miniature. The pigment will run to the edges and create those horrible watermarks that we all hate. Unloading is not optional — it's mandatory! And speaking of brushes, if you want to make the right choice, head over to my article on how to choose brushes for your miniatures.

Step 3: The brushstroke and the virtue of patience

With the brush ready, the moment of truth arrives. The direction of the brushstroke is essential for the transition to come out smooth and natural. The rule is simple:

Always drag the colour from the lightest area towards the darkest.

That way, the little pigment left in the brush is deposited at the end of the stroke, right where you want to add depth. If you do it the other way around, you'll be dragging the dark tone towards the light, smearing all the previous work.

Each glaze layer is extremely thin, almost invisible. Don't expect a dramatic change with the first brushstroke. The magic of this technique lies in the build-up of many layers, letting each one dry completely before applying the next. Luckily, we're talking about super-fast drying — barely 1 or 2 minutes.

Be patient. Apply a layer, wait, apply another... and watch in amazement as the transition comes to life little by little.

Practical applications and advanced tricks for glazing

Alright, you've got the technique down. Now is when the real fun begins, the moment when glazing with acrylic paint goes from being just another technique to your secret weapon for leaving people speechless when they see your minis.

Once you get the hang of dilution and how to place your brush, a whole new world opens up. I'm going to share some of my favourite uses, those little aces up my sleeve I've collected over the years that make a brutal difference on the display shelf.

Colour transitions so smooth you won't even notice them

This is the star application, the reason many of us dive into the world of glazing. It's simply the best way to achieve soft, perfect gradients on fabrics, cloaks, or even armour pieces.

Picture this: you've got a red cloak painted, with its highlights and shadows already in place, but the jump between tones is a bit harsh. Instead of settling for it, you start applying very, very thin glazes of the mid-tone right at that boundary. Layer by layer, you'll watch the colours blend as if by magic. It's incredible.

Shadows with more depth and chromatic richness

Tired of your shadows being nothing but flat, lifeless dark patches? Stop shading with black or dark browns, which often just end up "muddying" the base colour. Try applying glazes with colours you wouldn't expect:

• Purple or dark violet: Absolutely brilliant for shadows over warm colours like reds and oranges. It also works wonderfully on skin tones to give them a more lively appearance.
• Dark blue or turquoise: A classic for creating cool, realistic shadows on metals, white armour, or any grey surface.
• Dark green: Perfect for enriching the shadows of earthy tones, yellows, or even golds.

This simple change gives the miniature a depth and visual richness that will surprise you. If you want to nail these combinations, I recommend checking out my guide on colour theory for miniatures, which will come in really handy.

My top tip: Using glazes to fix disasters. It's happened to all of us: you get carried away with a highlight and end up with a blotch that looks like a sticker. Don't panic! A very diluted glaze of the mid-tone, applied carefully over the entire area, will blend everything together and soften that horrible transition. Works like a charm.

Realistic skin tones and special effects

Achieving a skin tone that looks truly convincing is one of the biggest challenges when painting minis. Glazes are, without a doubt, your best allies. By applying translucent layers of very diluted reds, blues, or browns in key areas (cheeks, under the eyes, the beard area), you give the face a life and realism that simply can't be achieved any other way.

And as if that weren't enough, glazing is the ultimate technique for lighting effects like OSL (Object Source Lighting). Want a scout's lantern or a magic sword to look like it's actually emitting light? Apply very diluted glazes of the light's colour (an electric blue, a phosphorescent green) onto nearby surfaces. You gradually add layers, building up intensity, and the glow effect you achieve is spectacular.

Conclusion: Go for it with glazes!

We've reached the end, and now you have up your sleeve one of the most powerful and rewarding techniques in the world of miniature painting: acrylic glazing.

We've already broken down what they are, the materials you can't do without, my personal method so you don't get lost, and how to get out of the most typical jams.

Now the ball is in your court. The most important thing is that you dive in and don't be afraid to experiment with your figures. Think of every resin miniature as a canvas waiting for you to bring it to life, and with glazes you're going to achieve a level of realism and depth that will blow your mind.

So, let's get to it! Grab your Vallejo acrylic paints, your brushes for glazing and start playing with those thin layers of colour. I promise the results are going to amaze you.

And if you're missing something in your arsenal, you already know that at the Mr Resin store we've got your back with the best materials. Above all, don't go without that Vallejo Glaze Medium which, I can assure you, is a game changer. Let's get painting!
