Applying glue to models, particularly plastic models using liquid cement, often involves a technique that utilizes capillary action to draw the adhesive into the join.
Applying Liquid Cement with a Brush
Based on common techniques for plastic models, particularly liquid cements which are thin and work by melting the plastic surfaces slightly, a specific method involves applying the glue after the parts are aligned and held in place.
Here is a step-by-step guide on how to apply liquid cement glue using a brush, as demonstrated in modelling resources:
- Prepare the Parts: Ensure the two plastic parts you want to join fit together correctly and are held firmly in their final position, creating a seam.
- Touch the Brush to the Seam: Using a brush (often included with the glue or a dedicated modelling brush), touch the tip directly to the seam where the two parts meet.
- Allow Glue to be Drawn In: Due to capillary action, the liquid glue will be drawn into the seam from the brush.
- Squeeze Parts Together: While the glue is wet and has flowed into the seam, squeeze the parts together to ensure a tight bond.
- Continue Along the Seam: Repeat the process of touching the brush to subsequent sections of the seam, allowing the glue to flow in, and then squeezing the parts until the entire join is secured.
This method allows the glue to evenly spread within the joint, creating a strong, seamless bond as the plastic surfaces fuse and then re-harden. It is a common technique when using thin liquid plastic cements.
