What You'll Learn
Painting plastic miniatures and models
Preparing the Miniatures:
Before you begin painting, it is crucial to properly prepare your plastic miniatures. First, remove the parts from the plastic sprue and clean off any excess mould lines using a hobby knife. It is recommended to assemble the entire miniature before proceeding to the next step. Use plastic cement or super glue to adhere the pieces together. Assembling the model beforehand gives you a better idea of its overall appearance and size, allowing you to identify any gaps or blemishes that need filling.
Cleaning and Priming:
Plastic model kits often have residual lubricants or oils on their surfaces due to the manufacturing process. Therefore, it is essential to wash the model parts with soap and water to ensure the paint adheres well. Once the miniatures are clean and dry, it's time to prime them. Primer helps the paint stick to the plastic surface and provides a base for your colours. Spray primers are commonly used, but be mindful of the distance and environmental conditions when applying to avoid a dusty or uneven finish.
Choosing Paints and Brushes:
Acrylic paints are the most popular choice for painting miniatures as they dry quickly and are easy to work with. Invest in a variety of brush sizes to accommodate different levels of detail. Additionally, have paper towels handy for wiping off excess paint and cleaning your brushes.
Painting Techniques:
When applying paint, be cautious to avoid leaking dark colours into unwanted areas. Stay within the lines and apply thin coats to avoid a "coffee-stained" look. If mistakes happen, use a paper towel to soak up the excess paint, or wait until it dries and cover it with a small amount of white paint. It is challenging to paint over mistakes without reactivating the underlying paint. Some painters choose not to paint the eyes, opting instead to focus on the overall model's appearance.
Practice and Experimentation:
Practising on cheaper miniatures or those from board games is a great way to start without the fear of making mistakes. Metal miniatures are also forgiving as paint can be easily stripped off and redone. Experiment with different brands of paints and primers to find what works best for you.
By following these steps and continuously practising, you'll be well on your way to creating stunning plastic miniature masterpieces. Enjoy the process, and don't be afraid to make mistakes—they are all part of the learning journey!

Different types of plastic
Plastic is everywhere, from our televisions, computers, and cars to our houses, refrigerators, and clothing. However, not all plastics are created equal. There are dozens of different types of plastics, each with unique properties and uses.
One of the most common plastics is polyethylene, which can be manufactured in varying densities, giving it unique physical properties. It is widely used in product packaging and is easily recyclable. Polyethylene is also the base material for UHMWPE, a highly abrasion-resistant plastic used in military body armor, hydraulic seals, and bearings, as well as artificial ice skating rinks.
Another commonly used plastic is polyvinyl chloride (PVC), known for its strength and durability. It is often used in construction materials, doors, windows, bottles, and non-food packaging. PVC can be manufactured to have rigid or flexible properties, making it ideal for a wide range of applications.
Polycarbonate is another important plastic, known for its toughness, stability, and transparency. It is as clear as glass but much stronger and can be easily worked, molded, and thermo-formed or cold-formed. Polycarbonate is commonly used in products such as sunglasses, police riot gear, DVDs, and greenhouses.
Polystyrene is a lightweight and inexpensive plastic that can be solid or foamed. It is widely used in beverage cups, insulation, packing materials, egg cartons, and disposable dinnerware. However, polystyrene is not easily recyclable and is considered environmentally unfriendly as it is not biodegradable and can be harmful to animals that mistake it for food.
Other types of plastics include acrylic, a transparent thermoplastic used as a lightweight and shatter-resistant alternative to glass, and PET (Polyethylene Terephthalate), which has excellent chemical resistance and a high strength-to-weight ratio. PET is commonly used in food containers, liquid containers, and engineering resins.
These are just a few examples of the many different types of plastics that exist, each designed for specific applications and uses.

Plastic products in daily life
Plastic is a material that has various applications in daily life. It is used to make a wide range of products that we interact with every day. Some common examples of plastic products include plastic bottles, bags, straws, lids, and food packaging. Plastic bottles, for instance, are popular due to their lightweight nature compared to glass bottles, making them convenient for carrying and transporting. However, plastic bottles are typically intended for single-use and are not recommended for refilling and reuse, which contributes to their limited useful life.
In addition to packaging and containers, plastic is also used in the construction industry. For instance, soft PVC (polyvinyl chloride), which is made elastic and soft through the addition of phthalates, is found in flooring, wallpapers, shower curtains, paints, and varnishes. Phthalates are commonly used in PVC, comprising between 30% and 35% of the material on average. This type of plastic is also used in the automotive industry for underbody protection, seals, and interior linings, as well as in the medical field for infusion bags, tubes, and enteric coating for tablets.
Plastic products have become ubiquitous in our daily lives due to their versatility, low cost, and convenience. They are used in various industries, including food and beverage packaging, healthcare, and construction. For example, plastic bags made of polyethylene or polypropylene have become a symbol of consumer society, with approximately 600 billion bags produced annually worldwide. Each European citizen uses about 500 plastic bags per year on average.
The use of plastic in our daily lives also extends to smaller items such as buttons, earrings, and Christmas tree decorations, which can be made from colourful and shiny plastic materials. Additionally, plastic is used in crafting and modelling supplies, such as polystyrene sheets, vinyl, and adhesive-coated plastic. These products are often sold online through platforms like Etsy, where crafters and hobbyists can find a variety of plastic materials for their projects.
While plastic has become an integral part of our daily lives, it is important to consider its environmental impact. Plastic debris from the food and packaging industries often ends up in the oceans, contributing to pollution and posing risks to marine life. There is a growing focus on the production of bioplastics as an alternative to conventional plastics, driven by ecological concerns and economic arguments. However, the environmental benefits of bioplastics, which can be derived from sources like maize, wood, sugar, or potatoes, are still debated, as their entire life cycle may not necessarily be more sustainable.

Making plastic shiny
Plastic is usually manufactured to have a glossy sheen, but this nice finish becomes dull over time and gives the plastic a cloudy look. Luckily, there are several ways to make plastic shiny again.
Cleaning
A good cleaning can sometimes be enough to restore a plastic item's shine. Start by washing your plastic item with a mild cleanser to remove dirt, grease, and debris. Soap and water will usually do the trick, but for more stubborn stains, a mixture of vinegar and water can help. Use a one-to-one dilution ratio and apply the mixture with a clean, dry cloth.
Buffing
Once your plastic item is clean, you can try buffing out any remaining scratches. Toothpaste is a surprisingly effective buffing agent. Simply apply a small amount to a cotton swab and rub it into the scratches in a circular motion. Wipe off any excess toothpaste with a damp cloth. Alternatively, you can use baking soda. Mix a few drops of water into some baking soda to create a paste, then apply it to the scratches with a soft, clean cloth in small, circular motions.
Sanding
For deeper scratches, you may need to use sandpaper. Start with fine-grained sandpaper and work your way up to progressively coarser grits, always dipping the paper in water before use to minimize friction and heat. Start with 800-grit, then move to 320-grit, and finally 400-grit. The finer sandpaper produces a smoother finish.
Polishing
After you have removed all the scratches, you can use a polishing compound or a buffing wheel to restore the plastic's shine. Metal polish is highly effective and widely available.
By following these simple steps, you can easily make plastic shiny again and keep it looking new for a long time.
