It’s a versatile mix additive and non-catalyzed clear that artists, custom painters and hobbyists use to reduce cratering, increase film strength and apply heavier wet coats without compromising finish quality.\u003c\/p\u003e\n\n\u003ch3\u003eHow does 4030 Intercoat improve paint flow and leveling?\u003c\/h3\u003e\n\u003cp\u003eWhen added to Createx Colors paints, 4030 acts as a flow enhancer that reduces surface tension and helps wet paint plane out smoothly. That means fewer brush or spray marks and a more uniform finish even with heavier coats.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMix ratio: typically 10–30% by volume for improved flow.\u003c\/li\u003e\n  \u003cli\u003ePrevents cratering when applying heavier wet coats.\u003c\/li\u003e\n  \u003cli\u003eWorks across all Createx water-based paint lines.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan 4030 Intercoat help paint stick to plastics, vinyl and resin?\u003c\/h3\u003e\n\u003cp\u003eYes—4030 functions as an adhesion promoter when blended with water-based paints, enhancing bonding to substrates that can be difficult to paint.

Always stir thoroughly and perform a small test spray to dial in atomization and flash times for your environment.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eStart at 10% and increase up to 30% for heavier flow and leveling.\u003c\/li\u003e\n  \u003cli\u003eTest spray on scrap to confirm atomization and coverage.\u003c\/li\u003e\n  \u003cli\u003eFollow normal surface preparation: clean, scuff, and allow sufficient flash time between coats.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: Createx 4030 Intercoat is ideal for airbrush artists, custom auto and helmet painters, prop makers, scale modelers and craft hobbyists who want stronger, smoother water-based finishes. If you need better leveling, improved adhesion to tricky substrates, or a tougher air-dry coating without switching to solvent systems, this additive is a practical tool for both studio and shop use.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What mix ratio should I use for Createx 4030 Intercoat?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Start with 10% by volume and increase up to 30% as needed; test spray to adjust for flow and atomization.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is 4030 Intercoat compatible with all Createx Colors paints?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes. 4030 is compatible with Auto Air, Airbrush, Wicked and Illustration Colors and is water-soluble.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Createx","offers":[{"title":"Default Title","offer_id":55163222458711,"sku":"B018N98N2G","price":31.23,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/createx-4030-intercoat-front.jpg?v=1790342230","url":"https:\/\/britishgarage.co.uk\/products\/createx-4030-intercoat-mix-additive-8-oz-water-soluble-polyurethane-clear-for-improved-flow-adhesion-and-durability","provider":"British Garage","version":"1.0","type":"link"}
