Model cement, often referred to simply as plastic cement, is an essential tool for any scale model enthusiast. Whether you are building cars, airplanes, ships, or any other type of model, having the right kind of cement can make all the difference in ensuring a smooth and seamless construction process. In this article, we will delve deeper into the world of model cement and provide you with everything you need to know to make the most of this crucial tool.
## What is model cement?
Model cement is a type of adhesive specifically designed for plastic models. It is a solvent-based glue that works by chemically melting the surfaces of two plastic pieces and bonding them together as the solvent evaporates. This creates a strong and durable bond that is essential for ensuring the structural integrity of your model.
## Types of model cement
There are several different types of model cement available on the market, each with its own unique properties and uses. The most common types include:
– **Liquid cement**: This is the most popular type of model cement and is ideal for bonding larger pieces together. It comes in a bottle with a small brush applicator that allows for precise application to the model parts.
– **Tube cement**: Tube cement is a thicker, gel-like adhesive that is perfect for filling in small gaps and cracks in your models. It is less messy than liquid cement and is great for fine detail work.
– **Polystyrene cement**: Also known as plastic cement, this type of adhesive is specifically formulated to bond polystyrene plastic, which is commonly used in model construction. It creates a strong chemical bond that is perfect for building models from scratch.
– **Super glue**: While not technically a model cement, super glue can also be used in model construction for certain types of materials. It is a quick-drying adhesive that is ideal for bonding metal, wood, and other materials that plastic cement may not work on.
## How to Use model cement
Using model cement is a relatively straightforward process, but there are a few tips and tricks that can help you achieve the best results. Here are some steps to follow when using model cement:
1. **Prepare the surfaces**: Before applying the cement, make sure to clean the surfaces of the model parts to be bonded. This will remove any dirt, dust, or oil that could interfere with the bonding process.
2. **Apply the cement**: Using a small brush or applicator, apply a small amount of cement to one of the surfaces to be bonded. Be careful not to use too much glue, as this can lead to messy excess that will need to be cleaned up later.
3. **Join the parts**: Press the two surfaces together firmly and hold them in place for a few moments to allow the cement to set. Avoid moving the parts around too much while the glue is drying, as this could weaken the bond.
4. **Clean up**: Once the glue has dried, use a hobby knife or sandpaper to remove any excess cement from the model. This will give your model a clean and professional finish.
## Tips for Working with Model Cement
– **Ventilation**: Model cement contains strong solvents that can be harmful if inhaled. Always work in a well-ventilated area or wear a mask to protect yourself from fumes.
– **Precision**: Model cement sets quickly, so it is important to work with precision and avoid mistakes. Practice applying the cement on scrap pieces before working on your actual model.
– **Storage**: Keep your model cement tightly sealed when not in use to prevent it from drying out or evaporating.
## Where to Buy Model Cement
Model cement can be purchased at hobby shops, craft stores, or online retailers that specialize in model building supplies. There are many different brands and types of cement to choose from, so be sure to read reviews and do some research before making a purchase.
In conclusion, model cement is an essential tool for any scale model enthusiast. By understanding the different types of cement available, how to use it effectively, and following some helpful tips, you can create stunning models with strong and durable bonds. So next time you embark on a model building project, be sure to have some model cement on hand to bring your creations to life.
