What You'll Learn
Acrylic paint is the best for miniatures
Acrylic paint is the most commonly used paint for miniatures. It is easy to work with, dries quickly, and can be thinned with water to apply very fine layers. Acrylic paints are also versatile and can be used on almost any surface, including plastic, metal, resin, canvas, wood, and glass. They are also non-toxic and easy to clean up, making them a good option for beginners.
Acrylic paints come in a wide variety of forms, including artist-quality tube paints and craft paints. Artist-quality paints have a more saturated pigment and less filler, resulting in brighter colours and better coverage. Craft paints, on the other hand, tend to be more opaque and may not be rated for pigment content or lightfastness. When choosing an acrylic paint for miniatures, it is important to consider the pigment load, coverage, flexibility, non-toxicity, and ease of cleanup.
To prepare plastic miniatures for painting, it is recommended to rinse them with soap and water to ensure the best results. Once the miniature is clean and dry, it is best to fully assemble it using plastic cement or super glue. This helps to ensure a better understanding of the model's overall appearance and size. Additionally, it is important to remove any excess mould lines and glue before painting.
When painting plastic miniatures with acrylic paint, it is important to use proper undercoats and overcoats to prevent the paint from absorbing moisture. This is because acrylic paints are hygroscopic and will swell slightly with moisture. Applying a clear coat varnish or a matte varnish like Testors Dullcote can help protect the paint job from scratches, wear, and tear, as well as create a uniform finish.
Overall, acrylic paint is a popular choice for painting miniatures due to its ease of use, quick drying time, versatility, and low toxicity. With the right techniques and preparation, acrylic paint can help bring your miniatures to life.

Primer is key for paint to stick
Painting plastic miniatures is a fun and rewarding hobby, but it can be a little intimidating for beginners. One of the most important things to remember is that primer is key to making sure your paint job sticks and lasts.
Priming your miniatures is one of the first things you should do after assembly. It is important because it provides a surface for the paint to stick to. Without primer, paint can flake or chip off easily, especially from slippery surfaces like bare plastic. Primer paints are specially formulated to stick to bare plastic and create a slightly rougher texture for the paint to adhere to. This helps to prevent issues like paint beading up or rubbing off in high-touch areas.
When priming, it is recommended to use very thin coats of primer. This helps you control the amount applied and gives a slightly rough surface for the paint to stick to better. A well-cleaned miniature will typically have a shiny surface, so it is important to use a flat or "matte" primer that is non-reflective. Spray with short bursts of primer, holding the miniature about a foot away from the spray can. It is also helpful to use a primer that is a different colour than the miniature, as this will help you determine when you have applied enough.
There are many different types of primers available, including spray primer, airbrush primer, and brush-on-by-hand primer. It is important to choose a primer specifically designed for miniatures or model painting, as general-purpose primers may not bond well with plastics. Some popular options include the Army Painter Color Primer, which comes in a variety of colours, and Stynylrez, a self-levelling primer that works on a variety of surfaces.
By using the right primer and applying it correctly, you can ensure that your paint job on plastic miniatures will last and look great.

Varnish to protect from scratches
When it comes to painting plastic miniatures, it is important to consider the type of paint and varnish you will be using. The best paint for plastic miniatures should have a high pigment load for bright colours, good coverage on a variety of surfaces, flexibility when dry, non-toxicity, and ease of cleanup. Acrylic paints are a popular choice for miniatures as they are easy to use and clean up, quick to dry, and can be used on almost any surface with a suitable primer.
To protect your paint job from scratches and other wear and tear, consider using a varnish. A varnish will act as a protective layer over your paint, helping to prevent chipping and colour distortion. It is important to note that not all varnishes are created equal, and the type of varnish you use will depend on the desired finish and level of protection you need. Here are some things to consider when choosing a varnish to protect your plastic miniatures from scratches:
Types of Varnish
There are three main types of varnish: gloss, satin, and matt. Gloss varnishes tend to have stronger protective qualities, while matt varnishes offer minimal additional protection. Satin varnish falls somewhere in the middle and can provide a good balance between protection and finish. However, it is important to note that the glossier the varnish, the more it can affect the overall look of your miniature, making it appear out of place on a table or next to other miniatures with a more matt finish.
Number of Coats
The number of coats of varnish you apply will also affect the level of protection. For plastic miniatures, one coat is usually sufficient, but you may need more if the miniature has spikes, edges, or other parts that are frequently handled or likely to chip. In general, the more coats you apply, the stronger the protection, but be mindful of colour distortion, which can occur with multiple coats of varnish.
Varnish Brands
When choosing a varnish brand, look for a product that is clear, extra tough, and non-yellowing. Avoid varnishes that crack or frost, as these will not provide adequate protection. Some recommended brands include Vallejo's Satin Varnish and Army Painter Matt Spray. If using a matt varnish, consider Testors Dullcote, which can help protect against scratches and create a uniform finish.
Application Techniques
When applying varnish, be sure to follow the manufacturer's instructions and allow each coat to dry thoroughly before applying the next. Consider using a spray varnish, as it can be easier to apply evenly and may provide better coverage. You can also use a brush to apply varnish, but be careful not to overbrush, as this can affect the finish.
In summary, when choosing a varnish to protect your plastic miniatures from scratches, consider the type of varnish, the number of coats, the brand, and the application technique. By taking these factors into account, you can ensure that your miniatures are well-protected and look their best.

Water-based vs. solvent-based paint
Water-based and solvent-based paints are two broad classifications of paint. Water-based paints use water as their solvent, while solvent-based paints use organic solvents like mineral spirits or turpentine.
Water-based paints are generally easier to apply and clean up, as they can be mixed with water. They are also more environmentally friendly due to lower levels of volatile organic compounds (VOCs), which pose health risks such as headaches, dizziness, and long-term respiratory issues if inhaled. They also emit less odour and are safer for indoor use, especially in spaces with limited ventilation. Modern water-based paints have improved significantly in terms of durability and finish, making them suitable for a wide range of applications. Additionally, water-based paints are a good option for projects that traditionally used solvent-based paints, such as wood and metal, as they often don't require a primer.
Solvent-based paints, on the other hand, have their own advantages. They are ideal for low-temperature applications, as water-based paints are more affected by temperatures close to freezing. Solvent-based paints also have better resistance to chemicals and solvents.
When choosing between water-based and solvent-based paints for plastic miniatures, it is important to consider the working environment and the specific properties and advantages of each type of paint. Water-based paints are a good option for beginners and for use in enclosed spaces or around family, as they are easier to work with and have lower VOC emissions. Solvent-based paints may be preferred by more experienced painters who can take the necessary health and safety precautions, such as wearing a respirator and ensuring adequate ventilation.

Cheap craft paint is not recommended
When it comes to painting plastic miniatures, the type of paint you use is important. While you may be tempted to reach for cheap craft paint, it's important to remember that these paints are not specifically designed for this purpose and may not yield the desired results. Here's why cheap craft paint is not recommended for painting plastic miniatures:
- Formula: Cheap craft paints from supermarkets or general craft stores may not have the right formula for small, detailed surfaces like plastic miniatures. They may lack the necessary pigment density, vibrancy, and lightfastness, resulting in dull or uneven colours that fade over time.
- Precision: Miniature painting requires precision, and cheap craft paints may not offer the level of precision needed. They may be too runny or difficult to control, making it hard to achieve the desired level of detail and accuracy.
- Coverage and Adhesion: High-quality miniature paints are designed to adhere well to plastic surfaces and provide good coverage. Cheap craft paints may not have the same adhesion properties, resulting in paint that chips or peels off easily.
- Durability: Cheap craft paints may not be as durable as specialized miniature paints. They could be more prone to scratches, chipping, or other types of wear and tear, which can ruin the aesthetics of your miniatures.
- Compatibility: Some cheap craft paints may not be compatible with other materials commonly used in miniature painting, such as primers, varnishes, and thinners. This can limit your options and make it difficult to achieve the desired effects or protect your work with a clear coat.
- Learning Curve: While it's true that more expensive paints don't always equate to better results, investing in higher-quality miniature paints can offer a better learning experience. With their superior coverage, adhesion, and colour options, you can focus on honing your painting skills without the added frustration of working with inferior materials.
In summary, cheap craft paint may save you money in the short term, but the potential drawbacks in terms of quality, durability, and precision may end up costing you more in the long run. It's worth investing in specialized miniature paints, such as acrylics, to ensure better results and a more enjoyable painting experience.
