Model cement, often referred to as plastic cement or polystyrene cement, is an essential tool for any scale model enthusiast. Whether you are building model airplanes, cars, ships, or buildings, model cement is used to securely bond plastic parts together. Understanding the different types of model cement and how to use them effectively can make a significant difference in the quality of your finished model. In this comprehensive guide, we will cover everything you need to know about model cement and how to use it like a pro.
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 of model cement include:
1. Liquid Cement: Liquid cement is a thin, watery adhesive that comes in a bottle with a brush applicator. It is ideal for joining small parts and creating seamless seams. Liquid cement works by melting the plastic surfaces of the models, allowing them to fuse together when pressed. This type of cement dries quickly and creates a strong bond.
2. Tube Cement: Tube cement is a thicker, gel-like adhesive that comes in a small tube with a pointed nozzle. It is best suited for bonding larger parts and filling gaps between pieces. Tube cement has a longer drying time compared to liquid cement, allowing for adjustments to be made before the bond is fully set.
3. Super Glue: Super glue, also known as cyanoacrylate adhesive, is a fast-acting adhesive that bonds quickly and securely. While not technically a model cement, super glue is commonly used in model building for attaching metal, wood, or other materials that plastic cement may not bond effectively.
How to Use model cement
Using model cement may seem straightforward, but there are a few tips and tricks to keep in mind to ensure a successful bond:
1. Clean the Surfaces: Before applying model cement, make sure that the surfaces to be bonded are clean and free of any debris, oil, or mold release agents. This will help the cement adhere better and create a stronger bond.
2. Apply Cement Sparingly: It is important not to overapply model cement, as excess adhesive can ooze out and create unsightly messes or damage the plastic surfaces. Use a small amount of cement and apply it only to the areas to be bonded.
3. Hold Parts Together Firmly: After applying the model cement, press the parts together firmly to ensure a strong bond. Hold the parts in place for a few minutes until the cement sets and the bond is secure.
4. Allow Sufficient Drying Time: Depending on the type of model cement used, drying times can vary. It is essential to allow the cement to fully cure before handling the bonded parts to prevent weakening the bond.
5. Cleanup: Model cement can be messy, so it is important to clean up any excess adhesive with a cotton swab or a small brush dipped in cement thinner. This will help maintain the appearance of your model and remove any unwanted cement residue.
Safety Precautions
When working with model cement, it is essential to take necessary safety precautions to protect yourself and your work area:
1. Work in a well-ventilated area to avoid inhaling the fumes from the cement.
2. Wear gloves to protect your skin from contact with the adhesive.
3. Avoid getting cement in your eyes or mouth and wash your hands thoroughly after handling.
4. Keep model cement out of reach of children and pets, as it can be harmful if ingested.
In conclusion, model cement is a versatile adhesive that is essential for any scale model builder. By understanding the different types of model cement available and following proper techniques for application and cleanup, you can achieve professional-looking results in your model projects. Remember to practice safety precautions when working with model cement to protect yourself and your creations. Happy modeling!
