Which tool do you use to remove the excess sealant after injection sealing?

Using MPK solvent and a clean cloth to remove excess sealant after injection sealing is an appropriate method because it effectively dissolves and lifts away uncured sealant without damaging the surrounding surfaces. The solvent is designed to break down the chemical properties of sealants, allowing for efficient cleanup while avoiding potential scratches or gouges that might occur with other methods.

Additionally, the use of a clean cloth ensures that any residue is captured without merely smearing it around, which could lead to a larger mess or uneven surfaces. This process is crucial in aerospace assembly, where cleanliness and precision are paramount to ensure the integrity of components and maintain safety standards.

While other tools like vacuum cleaners could assist in removing debris or larger particles, they are not specified for sealant removal. Razor blades might be used for scraping but carry the risk of damaging surfaces or creating further complications. Brushes may also risk leaving fibers behind or may not effectively remove the sealant. Therefore, utilizing MPK solvent with a clean cloth represents the best practice for this task.
