When it comes to spray paint for plastic models, there are a variety of options available. The best spray paint for plastic models will depend on factors such as budget, desired finish, and type of plastic. Tamiya is a well-known and highly regarded brand for model spray paints, offering a range of colours and finishes that provide excellent coverage and a premium finish. For those on a budget, Krylon spray paint is a more affordable option, although the finish may not be as refined. Mr. Hobby's Mr. Surfacer is another popular choice, offering quick-drying and durable paint with the only drawback being its strong odour. Lacquer paints, such as Testors lacquer, are also commonly used for plastic models, providing a high-shine finish.

What You'll Learn
Lacquer paints
Lacquers are the least commonly used type of paint for plastic models due to their difficulty and risk of use. They are the most toxic of the three main types of paint and should only be used in outdoor or well-ventilated areas. It is also recommended to wear a mask when handling lacquer paints. Lacquers have an extremely strong odour, which can be overpowering.
An example of a lacquer paint is Testors lacquer, which is easy to use and provides a great shine if care is taken. Check the compatibility first to avoid any bubbles from forming, and always apply light coats, allowing each layer to dry fully before applying the next.

Water-based paints
Another option for water-based paints is to use a lacquer thinner with them. Tamiya Acrylics, for example, are a type of acrylic lacquer paint that performs well with a lacquer thinner. These paints were originally marketed as a locally produced water-based paint for school children in Japan and the United States. Tamiya Acrylics are known for their impressive chemical engineering and are widely considered to be one of the best paints for plastic models, offering excellent coverage and a premium finish.
When using water-based paints, it is important to consider your working environment. These paints are a good choice when working indoors with family or others nearby, as they do not require the same health and safety precautions as solvent-based paints. However, if you are using an airbrush with water-based paints, it can be challenging for beginners to get the right consistency. Adding a small amount of food-grade organic solvent or a product like Flow Improver can help lower the surface tension of the water and make the paint easier to spray.
Overall, water-based paints offer a safe and effective option for painting plastic models. With a variety of brands and types to choose from, you can find the right paint for your specific needs and preferences. Remember to always test new paints on a small portion of your model before fully applying them, to ensure you achieve the desired results.

Budget options
If you are on a budget, Krylon spray paint is a good option. Krylon Fusion for Plastic is available on Amazon and is a good choice if you need to cover a large area with primer. However, do not expect the finish to be as good as the more expensive options.
Rust-Oleum Painter's Touch Multi-Purpose Spray Paint is another budget-friendly option. It is available on Amazon and is a good cheap spray paint. ARTarlei Permanent Paint Markers are also available on Amazon and are ideal for children's toys.
Tamiya is another brand that offers a range of affordable options. Their primer is renowned for being one of the best and is easy to work with, providing great coverage. Tamiya is also a good option for airbrushing, although it can be hard to find locally.
Mr. Hobby also offers a base paint that is highly rated and dries very quickly. This paint is perfect for military models, with its smooth finish and olive drab green color.
When choosing a spray paint for your plastic models, consider the type of material your model is made from. For example, if your model is made from polycarbonate, check that the paint is suitable for this material. You should also consider whether you need a primer or a base coat, as these have different purposes. The primer is important if you want your paint to adhere properly to the model, and the base coat is the main paint that you apply.

Drying and curing times
Type of Paint:
The type of paint used significantly affects drying and curing times. Enamel paints, for example, are known for their slower drying times, typically taking 8 to 24 hours to fully cure. On the other hand, acrylic spray paints dry faster, usually within 2 to 4 hours. Lacquer paints, including the popular Tamiya brand, are renowned for their quick-drying properties, often becoming dry to the touch in just 10 to 30 minutes. However, it's important to note that while lacquer paints dry quickly, they may not undergo a subsequent curing phase like other paints.
Temperature and Humidity:
Ideal drying conditions for spray paint involve warmth and low humidity. High humidity and low temperatures can significantly slow down the drying and curing process. For instance, painting in temperatures of 70°F (21°C) with 50% humidity can result in drying times of 1 to 2 hours. Conversely, colder and more humid conditions can extend the drying process to several hours or even days. Wind can also be a factor when painting outdoors, as it increases airflow and helps speed up drying times.
Surface Material:
The material of the plastic model being painted can impact drying and curing times. Plastic surfaces, in particular, present a unique challenge due to their smooth and non-porous nature, which can hinder paint adhesion. It is recommended to use a primer designed specifically for plastic to improve paint adhesion and speed up drying times. Additionally, thin coats of paint are advisable, as they dry faster than thick coats and help avoid issues like uneven coverage or a textured finish.
In summary, when working with spray paint on plastic models, it is crucial to consider the specific type of paint being used, the environmental conditions, and the characteristics of the surface. By following the recommended drying and curing times provided by paint manufacturers and making adjustments based on these factors, you can achieve optimal results and ensure your paint job cures to its full strength.
