How Often Should You Clean an Epoxy Spray Gun?

Why Frequent Cleaning is Essential

Epoxy resin begins to cure and harden shortly after use. Even a small amount left in your spray gun can clog the mechanism and significantly reduce its performance. Immediate cleaning after every use stops resin from setting inside the nozzle and internal parts, ensuring your tool operates efficiently with each project.

Step-by-Step Cleaning Routine

• Clean after every use: As soon as you finish spraying, dismantle the spray gun and flush all parts with a suitable cleaner such as Pure Isopropyl Alcohol 99.9% to dissolve and remove any remaining resin.
• Use gentle tools: Pair your cleaning solvent with lint-free microfibre cloths to avoid scratching sensitive parts.
• Repeat if necessary: If you notice any residue or stickiness, repeat the cleaning process before reassembly.

When Thorough Cleaning Matters Most

Regular cleaning after each use is especially vital when switching between different resin formulas or colours, after long sessions, or before storage. Neglecting this step can lead to poor spray quality or permanently damaged equipment.
