When it comes to building model kits, one of the most important tools in your arsenal is model cement. This adhesive plays a crucial role in ensuring that your models come together seamlessly and stay together for years to come. Whether you’re a seasoned modeler or just starting out, understanding the ins and outs of model cement is essential. In this guide, we’ll explore everything you need to know about model cement, from its uses and types to tips for using it effectively.
What is model cement?
Model cement, also known as plastic cement or polystyrene cement, is a special type of adhesive designed specifically for bonding plastic models. Unlike traditional glue, model cement chemically melts the plastic parts it comes into contact with, creating a strong, permanent bond. This makes it ideal for assembling plastic models, such as scale aircraft, cars, ships, and figures.
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 brush applicator, making it easy to apply to small parts and hard-to-reach areas. It dries quickly and forms a strong bond, making it ideal for basic assembly work.
2. Tube Cement: Tube cement is thicker than liquid cement and is typically used for bonding larger parts and seams. It also dries quickly and creates a strong, durable bond.
3. Cement with Extra Thin: Extra thin cement is formulated to flow into tight spaces and gaps, ensuring a seamless bond between parts. It is ideal for precision work and delicate assemblies.
4. Gel Cement: Gel cement has a thicker consistency than liquid cement, making it ideal for vertical surfaces and overhead applications. It provides a strong, reliable bond and is less likely to run or drip.
Tips for Using model cement
To get the best results with model cement, follow these tips:
1. Work in a well-ventilated area: Model cement emits fumes that can be harmful if inhaled, so be sure to work in a well-ventilated area or use a respirator mask.
2. Test fit parts before applying cement: Before applying cement, dry-fit the parts together to ensure they align correctly. Once you are satisfied with the fit, apply a small amount of cement to the mating surfaces.
3. Use the right amount of cement: Apply a thin, even layer of cement to the surfaces you wish to bond. Avoid using too much cement, as excess adhesive can ooze out and mar the surface of your model.
4. Use clamps or rubber bands to hold parts together: For larger parts or complex assemblies, use clamps or rubber bands to hold the parts together while the cement dries. This will ensure a tight, secure bond.
5. Clean up excess cement: If any cement spills or oozes out during assembly, use a cotton swab dipped in cement thinner to clean up the excess adhesive. This will help prevent unsightly smudges or marks on your model.
6. Allow time for the cement to cure: Model cement can take anywhere from a few minutes to several hours to fully cure, depending on the type of cement used and the ambient temperature. Be patient and allow the cement to set completely before handling or painting your model.
In conclusion, model cement is a versatile and essential tool for model builders of all skill levels. By understanding the different types of cement available, how to use them effectively, and following these tips, you can achieve professional-looking results and create models that will stand the test of time. So, the next time you embark on a model-building project, don’t forget to reach for your trusty bottle of model cement. Your models will thank you for it.
