Painting Plastic Models A Comprehensive Guide

Hey guys! Ever wanted to make your plastic models look extra awesome? Painting them is the way to go! It might seem a bit daunting at first, but trust me, it's super rewarding and a ton of fun. Think of it as leveling up your hobby game. We're going to dive deep into how to get those models looking fantastic, so buckle up and let's get started!

Choosing the Right Paints and Tools

Okay, first things first, you can't just grab any old paint and go to town. Choosing the right paints and tools is essential for achieving a smooth, professional-looking finish on your plastic models. Think of it like this: you wouldn't use a butter knife to carve a sculpture, right? Same principle here! Let's break down the key players in your painting arsenal.

Types of Paint

There are primarily two types of paint that modelers swear by: acrylics and enamels. Each has its own set of pros and cons, so let's take a closer look.

Acrylic Paints

Acrylic paints are water-based, making them super easy to clean up (yay for no harsh chemicals!). They dry relatively quickly, which is a huge plus when you're working on multiple layers. Plus, they come in a massive range of colors and finishes. For beginners, acrylics are often the recommended starting point. They're more forgiving and less stinky than enamels. However, they can sometimes be a bit fragile, and may require a good varnish to protect them. Also, layering acrylics can be tricky if the underlying layer isn't completely dry, as it can sometimes lift or blend. Brands like Vallejo, Citadel (Games Workshop), and Tamiya (acrylic) are popular choices among modelers.

Enamel Paints

Enamel paints, on the other hand, are solvent-based. This means they're tougher and more durable than acrylics, giving you a really hard finish. They also tend to self-level a bit better, which can result in a smoother coat. The downside? They take much longer to dry (we're talking hours, sometimes even days!), and the cleanup requires special thinners, which can be a bit harsh and smelly. Enamels are also less forgiving; mistakes can be harder to correct. However, the durability and smooth finish are a big draw for many experienced modelers. Humbrol and Model Master are well-known enamel paint brands.

Essential Tools

Besides the paint itself, you'll need a few key tools to get the job done right. Think of these as your trusty sidekicks in the painting adventure.

Brushes

A good set of brushes is crucial. Invest in a variety of sizes and shapes. Different brushes are good for different purposes. Small, fine-tipped brushes are perfect for those intricate details, while larger, flat brushes are great for base coats and larger areas. Both synthetic and natural bristle brushes have their place. Synthetic brushes are generally more durable and easier to clean, making them ideal for acrylics. Natural bristle brushes can hold more paint and are often preferred for enamels. Look for brushes that have a good point and don't shed bristles easily.

Palette

You'll need something to put your paint on! A palette keeps your paints organized and prevents them from drying out too quickly. You can use a dedicated painter's palette, a ceramic tile, or even a plastic plate. Wet palettes are a fantastic option for acrylics, as they keep the paint moist for longer, preventing it from thickening and drying on the palette. This helps maintain a smooth consistency and reduces paint waste.

Airbrush (Optional but Recommended)

Okay, an airbrush might seem like a pro-level tool, but hear me out! While you can definitely achieve great results with brushes, an airbrush can take your painting to the next level. An airbrush provides an incredibly smooth and even finish, especially on larger surfaces. It's also amazing for applying thin coats, which is crucial for building up colors and avoiding obscuring details. It does require a bit of an investment and some practice to master, but the results are worth it. If you're serious about model painting, an airbrush is something to consider. You'll also need an air compressor to power the airbrush.

Other Essentials

• Primer: This is super important! Primer helps the paint adhere to the plastic and provides a uniform base coat. We'll talk more about priming later. Think of it as the foundation for your masterpiece. Without a good primer, your paint might chip or peel easily.
• Thinners: If you're using enamels or an airbrush, you'll need thinners to adjust the paint consistency and clean your tools. Make sure you use the correct thinner for the type of paint you're using (enamel thinner for enamels, acrylic thinner for acrylics, etc.).
• Varnish: Varnish protects your paint job and gives it the desired finish (glossy, matte, or satin). It's like a protective shield for your hard work. A good varnish can prevent scratches, fingerprints, and fading.
• Masking Tape: Masking tape is essential for creating clean lines and painting multiple colors without them bleeding into each other. You'll want to use a low-tack masking tape that won't damage the paint or plastic. Tamiya masking tape is a favorite among modelers.
• Hobby Knife: A sharp hobby knife is essential for cleaning up plastic parts, removing mold lines, and other detail work. A dull knife can be dangerous and won't give you clean cuts.
• Cutting Mat: Protect your work surface with a self-healing cutting mat. This will prevent scratches and gouges on your table or desk.
• Paint Stirrers: Use paint stirrers (wooden sticks or even old toothpicks) to thoroughly mix your paints before using them. This ensures a consistent color and finish.
• Cotton Swabs and Paper Towels: These are essential for cleaning up spills, wiping away excess paint, and other general cleanup tasks. Keep a stash of them handy.

Preparing Your Model

Before you even think about cracking open those paint pots, you need to prepare your model. This is like prepping a canvas before you start painting a masterpiece. A little prep work goes a long way in ensuring a fantastic final result. Trust me, skipping this step is like building a house on a shaky foundation – it might look good at first, but it won't last.

Cleaning the Parts

First things first, give those plastic parts a bath! Seriously. Plastic model parts often have a mold release agent on them, which can prevent paint from adhering properly. Think of it as a greasy film that repels paint. Washing the parts in warm, soapy water (dish soap works great) removes this residue. Use a soft brush (an old toothbrush works well) to gently scrub the parts. Rinse them thoroughly and let them air dry completely. This step is crucial for ensuring a strong bond between the paint and the plastic.

Removing Mold Lines

Mold lines are those unsightly seams that run along the edges of plastic parts, left over from the molding process. They're like the wrinkles on a perfectly smooth face – you want to get rid of them! Use a sharp hobby knife or a seam scraper to carefully remove these lines. Gently scrape along the mold line, being careful not to gouge the plastic. For curved surfaces, sanding sticks or sanding sponges can be very helpful. Start with a coarser grit sandpaper and gradually move to finer grits for a smooth finish. Remember, patience is key here. It's better to remove too little material than too much.

Assembling the Model (Partially)

Depending on the model, it might be easier to paint some parts before assembling the entire thing. Think about which areas will be difficult to reach with a brush or airbrush once the model is fully assembled. Subassemblies (groups of parts that are assembled separately) can be a great way to tackle complex paint jobs. For example, you might paint the cockpit of an airplane model before attaching it to the fuselage. Use a good quality plastic cement to glue the parts together. Be careful not to use too much glue, as it can seep out and damage the surrounding plastic. Let the glue dry completely before moving on to the next step.

Priming: The Foundation of a Good Paint Job

We touched on priming earlier, but it's so important that it deserves its own section. Priming is the foundation of a good paint job. Think of it as the first coat of paint on a wall – it provides a smooth, uniform surface for the subsequent layers to adhere to. Primer also helps to fill in minor imperfections and can even enhance the color of your topcoats. There are two main types of primer: spray primers and brush-on primers. Spray primers are generally preferred for larger areas, as they provide a smooth, even coat. Brush-on primers are better for smaller details or hard-to-reach areas.

Choosing the Right Primer

When choosing a primer, consider the type of paint you'll be using for your topcoats. Acrylic primers are best for acrylic paints, and enamel primers are best for enamel paints. There are also universal primers that can be used with both types of paint. Primer comes in a variety of colors, including gray, white, and black. Gray primer is a good all-around choice, as it provides a neutral base for most colors. White primer can brighten up lighter colors, while black primer can add depth and richness to darker colors. You can apply primer with a brush or an airbrush. If you're using an airbrush, thin the primer according to the manufacturer's instructions. Apply thin, even coats of primer, allowing each coat to dry completely before applying the next. Avoid applying too much primer in one coat, as this can lead to runs and drips.

Painting Techniques

Alright, we've got our paints, tools, and model prepped and ready to go. Now comes the fun part: painting techniques! This is where you get to bring your model to life with color. There are a few key techniques that will help you achieve a professional-looking finish. Let's dive in!

Base Coating

The base coat is the foundation of your paint job. It's the first layer of color that you apply to the model. It's important to apply a smooth, even base coat, as this will affect the appearance of all subsequent layers. For a smooth base coat, use thin, even coats of paint. Avoid applying too much paint in one coat, as this can lead to runs and drips. If you're using an airbrush, hold it about 6-8 inches away from the model and move it in smooth, even strokes. Overlap each stroke slightly to ensure complete coverage. If you're using a brush, use a soft, wide brush and apply the paint in long, even strokes. Work in one direction, and avoid going back over areas that you've already painted. Let the base coat dry completely before moving on to the next step. The drying time will vary depending on the type of paint you're using.

Layering

Layering is a technique that involves applying thin coats of paint on top of each other to build up color and create depth. This technique is especially useful for creating realistic shading and highlights. To layer paint, apply a thin coat of paint to the area you want to shade or highlight. Let the paint dry completely, and then apply another thin coat. Repeat this process until you achieve the desired effect. You can use different colors of paint to create different effects. For example, you can use a darker shade of the base color to create shadows, and a lighter shade to create highlights.

Highlighting

Highlighting is a technique that involves adding lighter colors to certain areas of the model to make them stand out. This technique is used to create the illusion of light reflecting off the model's surface. To highlight, use a lighter shade of the base color and apply it to the edges, corners, and other prominent features of the model. You can use a brush or an airbrush to apply the highlights. If you're using a brush, use a fine-tipped brush and apply the paint in thin, controlled strokes. If you're using an airbrush, hold it at a slight angle to the model and apply the paint in short bursts.

Shading

Shading is the opposite of highlighting. It involves adding darker colors to certain areas of the model to create the illusion of shadows. This technique is used to add depth and realism to the model. To shade, use a darker shade of the base color and apply it to the recesses, creases, and other shadowed areas of the model. You can use a brush or an airbrush to apply the shadows. If you're using a brush, use a fine-tipped brush and apply the paint in thin, controlled strokes. If you're using an airbrush, hold it at a slight angle to the model and apply the paint in short bursts.

Drybrushing

Drybrushing is a technique that involves using a dry brush to apply paint to the edges and details of the model. This technique is used to create a weathered, textured look. To drybrush, dip a brush into paint, and then wipe off most of the paint on a paper towel. The brush should be almost dry. Then, lightly brush the brush over the edges and details of the model. The paint will catch on the raised surfaces, creating a textured effect. Use a stiff-bristled brush for drybrushing.

Detailing and Finishing

Okay, we've got our models painted, shaded, and highlighted. Now it's time for the really fun part: detailing and finishing. This is where you can add those extra touches that will make your model truly stand out from the crowd. Think of it as adding the jewelry and accessories to complete a stylish outfit.

Washes

Washes are thinned-down paints that are used to enhance the details and shadows on a model. They flow into the recesses and crevices, making them appear darker and more defined. This technique adds depth and realism to the model. To apply a wash, thin your paint with water or a thinner (depending on the type of paint you're using) until it has a watery consistency. Then, apply the wash to the entire model, or just to the areas you want to shade. Use a brush to work the wash into the recesses and crevices. Let the wash dry completely. Once the wash is dry, you can use a clean brush or a cotton swab to remove any excess wash from the raised surfaces. This will further enhance the contrast between the highlights and shadows.

Decals

Decals are thin pieces of paper with printed designs that can be applied to models. They're used to add markings, insignias, and other details. To apply a decal, first cut it out from the decal sheet. Then, soak the decal in warm water for about 20-30 seconds. This will loosen the adhesive. Slide the decal off the backing paper and onto the model. Position the decal carefully, and then use a soft brush or a cotton swab to smooth it out and remove any air bubbles. Use a decal setting solution to help the decal conform to the surface of the model. Let the decal dry completely before handling the model.

Weathering

Weathering is a technique that involves adding dirt, grime, and other effects to make the model look used and worn. This technique is often used on military models and other models that are supposed to look realistic. There are many different weathering techniques, including drybrushing, washes, chipping, and pigment powders. Experiment with different techniques to achieve the desired effect.

Varnish: Protecting Your Masterpiece

We talked about varnish earlier, but it's worth mentioning again. Varnish is essential for protecting your paint job from scratches, fingerprints, and fading. It also gives the model the desired finish (glossy, matte, or satin). Apply varnish in thin, even coats, allowing each coat to dry completely before applying the next. You can apply varnish with a brush or an airbrush. If you're using an airbrush, thin the varnish according to the manufacturer's instructions.

Common Mistakes to Avoid

Even the best model painters make mistakes from time to time. But knowing about some common pitfalls can help you avoid them and improve your results. Let's take a look at some mistakes you'll want to steer clear of.

Applying Paint Too Thickly

This is probably the most common mistake, especially for beginners. Applying paint too thickly can obscure details, create runs and drips, and make the paint take longer to dry. Always apply thin, even coats of paint, allowing each coat to dry completely before applying the next. Multiple thin coats are always better than one thick coat.

Not Letting Paint Dry Completely

Patience is a virtue, especially when it comes to model painting. Rushing the drying process can lead to smudging, fingerprints, and other imperfections. Always let each coat of paint dry completely before handling the model or applying the next coat.

Not Cleaning Your Brushes

Dirty brushes can ruin your paint job. Dried paint can stiffen the bristles and make it difficult to apply paint smoothly. Clean your brushes thoroughly after each painting session, using the appropriate cleaner for the type of paint you're using. For acrylic paints, water and soap will usually do the trick. For enamel paints, you'll need to use a paint thinner.

Skipping the Primer

We've said it before, and we'll say it again: don't skip the primer! Primer provides a smooth, uniform surface for the paint to adhere to, and it helps to prevent the paint from chipping or peeling.

Not Masking Properly

Masking is essential for creating clean lines and painting multiple colors without them bleeding into each other. Use a low-tack masking tape and apply it carefully, ensuring that it's firmly pressed down along the edges. If you're using an airbrush, mask off any areas that you don't want to be painted.
