The Ultimate Guide To Model Cement: Everything You Need To Know

Model cement, also known as plastic cement or polystyrene cement, is a crucial tool for anyone who loves building models. Whether you are a beginner or an experienced modeler, having the right type of cement can make a significant difference in the quality and durability of your final product. In this article, we will explore everything you need to know about model cement, its uses, types, and tips for using it effectively.

What is model cement?

Model cement is a specialized adhesive designed for bonding plastic parts together. It is commonly used in the construction of scale models, such as airplanes, cars, trains, and ships. Unlike regular glue, model cement chemically melts the plastic parts, creating a strong and permanent bond. This makes it ideal for joining plastic components that need to withstand pressure or stress, such as model kits that need to be assembled and painted.

Types of model cement

There are several types of model cement available on the market, each with its own unique properties and uses. The most common types include:

1. Liquid Cement: Liquid cement comes in a bottle with a needle-like applicator, making it easy to apply precise amounts of cement to small areas. It dries quickly and creates a strong bond, making it suitable for detailed work and fine-scale models.

2. Tube Cement: Tube cement is thicker in consistency compared to liquid cement and is packaged in a squeezable tube. It is useful for bonding larger plastic parts and filling gaps between pieces.

3. Cement Pen: Cement pens are convenient for applying cement to small areas or tight spaces that are hard to reach with a bottle or tube.

4. Super Glue: While not technically a type of model cement, super glue can be used as an alternative for bonding certain types of plastic parts together. However, it is not recommended for all plastic model kits, as it can be brittle and not as strong as dedicated model cements.

Tips for Using model cement

When working with model cement, it is essential to follow some best practices to ensure a successful and professional-looking result. Here are some tips for using model cement effectively:

1. Work in a Well-Ventilated Area: Model cement contains volatile fumes that can be harmful if inhaled in large quantities. Make sure to work in a well-ventilated area or use a mask to protect yourself from the fumes.

2. Test Fit Parts: Before applying cement, dry fit the parts together to ensure they align correctly and there are no gaps. This will help you avoid mistakes and ensure a seamless bond.

3. Use Small Amounts of Cement: It is better to apply multiple thin layers of cement than one thick layer. This will prevent excess glue from oozing out and ruining the appearance of your model.

4. Clean Excess Glue Immediately: If you accidentally apply too much cement, clean the excess glue with a cotton swab dipped in a solvent like acetone or nail polish remover. This will prevent visible smudges on your model.

5. Let it Dry Completely: Allow the cement to dry and cure fully before handling or painting the model. This will ensure a strong and permanent bond between the plastic parts.

Model cement is an essential tool for any model builder, providing a reliable and durable way to bond plastic parts together. By choosing the right type of cement, following best practices, and being patient during the assembly process, you can create stunning models that will withstand the test of time. So the next time you embark on a model building project, make sure to have model cement, the unsung hero of model making, by your side.
