Combined with filters, washes, dust effects, or chipping techniques, the warm primer tone can create natural variation that flat paint over grey primer may not achieve as easily.\u003c\/p\u003e\n\n\u003ch3\u003ePro-Tips from the Studio\u003c\/h3\u003e\n\n\u003cp\u003eTo get the most out of your \u003cstrong\u003e200ml bottle of Vallejo 74.644 Mecha Primer Sand\u003c\/strong\u003e, follow a simple application workflow:\u003c\/p\u003e\n\n\u003col\u003e\n\u003cli\u003eClean parts with isopropyl alcohol to remove mold release agents, oils, or sanding dust.\u003c\/li\u003e\n\u003cli\u003eSet your airbrush to around \u003cstrong\u003e20 PSI\u003c\/strong\u003e with a 0.3mm or 0.4mm needle.\u003c\/li\u003e\n\u003cli\u003eSpray from about \u003cstrong\u003e20cm\u003c\/strong\u003e away for smooth, even coverage.\u003c\/li\u003e\n\u003cli\u003eApply 2 thin coats instead of one heavy coat.\u003c\/li\u003e\n\u003cli\u003eAllow 30–60 minutes before topcoating, or longer before heavy masking.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe 20-20 Rule:\u003c\/strong\u003e Spray at about \u003cstrong\u003e20 PSI\u003c\/strong\u003e from a distance of around \u003cstrong\u003e20cm\u003c\/strong\u003e for a smooth satin primer layer.

The warm tone reads as a natural unpainted metal base that shows through at joint gaps and under wear effects. You are not just priming — you are building in the first layer of visual depth before the final paint color goes on.\u003c\/p\u003e\n\n\u003cp\u003eIf you are working on desert or Middle East armor, Sand also pulls double duty as a primer and first base coat in a single pass, which can reduce paint layers and save time. For anything that will end up white, very pale, or highly saturated, choose Ivory instead.\u003c\/p\u003e\n\n\u003ch3\u003eRelated Vallejo Mecha Primers\u003c\/h3\u003e\n\n\u003cp\u003eAlso available in the Mecha Primer range: \n\u003ca href=\"https:\/\/spraygunner.com\/products\/vallejo-mecha-color-mecha-primer-grey-200ml\"\u003eMecha Primer Grey 74.641\u003c\/a\u003e, \n\u003ca href=\"https:\/\/spraygunner.com\/products\/vallejo-mecha-color-mecha-primer-black-200ml\"\u003eMecha Primer Black 74.642\u003c\/a\u003e, \n\u003ca href=\"https:\/\/spraygunner.com\/products\/vallejo-mecha-color-mecha-primer-ivory-200ml\"\u003eMecha Primer Ivory 74.643\u003c\/a\u003e, and \n\u003ca href=\"https:\/\/spraygunner.com\/products\/vallejo-mecha-color-mecha-primer-white-60ml\"\u003eMecha Primer White 73.640\u003c\/a\u003e.\n\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\n\u003ctable style=\"width: 100%;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eFeature\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduct Reference\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e74.644\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eStore SKU\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e74644\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVolume\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e200ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eColor\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSand \/ warm beige primer tone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFinish\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSatin primer finish\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAirbrush primer; brush touch-up possible for small areas\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRecommended Needle Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.3mm or 0.4mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRecommended Pressure\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAbout 20 PSI for general use\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial Compatibility\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eStyrene plastic, ABS, resin, metal, and photo-etch parts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBest Uses\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGunpla, mecha kits, action figures, articulated models, armor, terrain, and desert camouflage bases\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eFrequently Asked Questions — Vallejo Mecha Primer Sand 74.644\u003c\/h2\u003e\n\n\u003ch3\u003eWhat surfaces does Vallejo Mecha Primer Sand work on?\u003c\/h3\u003e\n\u003cp\u003eMecha Primer Sand bonds to styrene plastic, ABS, resin, metal, and photo-etch parts.
