{ "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [ {"@type":"Question","name":"How to choose between HVLP and LVLP?","acceptedAnswer":{"@type":"Answer","text":"HVLP offers high transfer efficiency, saves paint, and is eco-friendly, making it the mainstream for repair work, but it requires a larger air source; LVLP consumes less air, suitable for small compressors and fine parts. Choose based on air source capacity and type of work."}}, {"@type":"Question","name":"Which is better, gravity-fed or siphon-fed?","acceptedAnswer":{"@type":"Answer","text":"Gravity-fed provides stable paint output, saves paint, and is easy to clean, suitable for fine touch-ups; siphon-fed has a larger cup capacity and allows continuous spraying for long periods, suitable for large areas. Neither is absolutely superior; it depends on the working conditions."}}, {"@type":"Question","name":"What pressure should the spray gun generally be set to?","acceptedAnswer":{"@type":"Answer","text":"There is no universal value; follow the coating manufacturer's recommendation. Clear coat is often at 2–3 bar, base coat is usually lower. Too high causes dry spray, too low causes sagging; always test spray first to confirm the spray pattern."}}, {"@type":"Question","name":"Why test spray every time you change paint?","acceptedAnswer":{"@type":"Answer","text":"Different coatings have different viscosities and solvent evaporation rates, requiring re-matching of pressure/paint output/fan width. Test spraying can reveal issues like asymmetric pattern, dry spray, or buildup before working on the actual part, avoiding wasted pieces."}}, {"@type":"Question","name":"Why clean the spray gun immediately after use?","acceptedAnswer":{"@type":"Answer","text":"Residual coating will cure and clog the nozzle and needle valve, affecting next time's atomization precision. Especially two-component (2K) coatings become extremely hard to clean after curing, so must be thoroughly cleaned with compatible solvent promptly after use."}} ] }
