Essentials for a Spotless Spray Gun
Pure Isopropyl Alcohol 99.9% – 1000ml Bottle for Epoxy Resin Projects & DIY easily dissolves uncured resin and evaporates residue-free, aiding both routine and deep cleaning. Strong Technical Degreaser for Resin Projects – 100% Natural Formula tackles persistent contamination without harsh chemicals. Use Coloured Microfibre Cloths for lint-free wiping and protection of delicate parts, and a Silicone Work Mat for Crafting and Epoxy Resin Projects – Easy-Clean Surface Protection to keep your workspace pristine and make clean-up easier.
Step 1: Disassemble and Prepare Your Work Area
Unplug and safely depressurise your spray gun according to the manufacturer’s guidance. Lay out all parts on your Silicone Work Mat for Crafting and Epoxy Resin Projects – Easy-Clean Surface Protection for easy access and organised cleaning. Always wear protective gloves and safety glasses. This safeguard prevents skin irritation from cleaning agents and accidental resin contact. Keep all small components, like needles and nozzles, in one area to avoid misplacement.
Step 2: Remove Fresh Resin Residues
Remove any remaining epoxy immediately after use. Use a soft brush or cloth to clear out obvious resin deposits inside the paint cup, nozzle, and gun body. For dissolving and wiping away residual resin, moisten a Coloured Microfibre Cloth with a small amount of Pure Isopropyl Alcohol 99.9% – 1000ml Bottle for Epoxy Resin Projects & DIY. Work swiftly, as epoxy hardens quickly once exposed to air.
Avoid abrasive scrubbing that could damage sensitive gun parts. Gently rub surfaces until residue is fully removed, taking care with soft seals or plastic elements.
Step 3: Thorough Degreasing and Deep Cleaning
For any oily deposits or more persistent contamination, treat parts with Strong Technical Degreaser for Resin Projects – 100% Natural Formula. Spray or apply a small amount to stubborn areas, allowing time for the formula to break down build-up before wiping clean. Rinse components with water if required by the cleaner’s instructions, then dry with fresh microfibre cloths. This step helps prevent clogging and ensures consistent resin flow in future projects.
Step 4: Clean and Inspect Nozzle and Needle Components
Clean nozzle and needle components thoroughly. Inspect these parts for resin build-up or obstruction. Use isopropyl alcohol and your soft brush for targeted cleaning in small cavities and channels. Check that airways and flow passages are completely clear. If needed, repeat the cleaning process on any stubborn residue zones.
Step 5: Dry, Reassemble and Store Properly
Let all parts dry completely before reassembly. Use fresh, dry microfibre cloths to ensure no moisture or cleaning residues remain. Carefully reassemble the spray gun, confirming all connections are secure but not over-tightened. Store the gun in a dust-free, dry area, ideally covered or boxed until next use. Periodic maintenance will keep your spray gun reliable and your resin finishes flawless.
Top Tips and Common Mistakes to Avoid
Clean your spray gun as soon as possible after use—delayed cleaning makes resin removal difficult. Never use metal tools to scrape inside; this can damage precision elements. Confirm compatibility of any cleaning agent with your gun’s materials before application, and always test on a small area if unsure. Schedule routine deep cleaning to prevent stubborn build-up and prolong equipment life.
