Instead of sanding or sandblasting to bare metal, this water-based formula converts active rust into a more stable compound and lays down a paintable latex primer layer. It’s designed for marine, automotive, household and industrial uses and cleans up with soap and water because it’s non-flammable and non-corrosive.\u003c\/p\u003e\n\n\u003ch3\u003eHow does Corroseal treat rust without sanding?\u003c\/h3\u003e\n\u003cp\u003eCorroseal’s chemistry reacts with iron oxide to transform flaky rust into magnetite, a dense black substance that adheres to the surface. That conversion stabilizes rust and prevents further rapid deterioration while providing a primed surface ready for topcoat application.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eConverts iron oxide (rust) into magnetite, not simply covering it\u003c\/li\u003e\n  \u003cli\u003eLeaves a black, stable coating that bonds to original metal\u003c\/li\u003e\n  \u003cli\u003eReduces need for heavy mechanical removal such as sandblasting\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I paint over Corroseal and what surface prep is required?\u003c\/h3\u003e\n\u003cp\u003eYes—Corroseal both converts rust and deposits a latex metal primer, so most topcoats adhere directly after the product dries and cures. Light surface cleaning to remove grease, loose scale and salt is recommended; heavy, loose rust can be brushed away first for better contact.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eClean with soap and water to remove oils and contaminants\u003c\/li\u003e\n  \u003cli\u003eRemove loose scale or flaking rust with a brush before application\u003c\/li\u003e\n  \u003cli\u003eAfter drying, prime is paint-ready for most latex or oil-based topcoats\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the application details and coverage I should expect?\u003c\/h3\u003e\n\u003cp\u003eApply Corroseal with a brush, roller or spray at a wet film thickness of roughly 8–10 mils for best results.

Clean brushes and tools with soap and water immediately after use; follow safety labels for ventilation and protective gear.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eWater-based formula; cleans up with soap and water\u003c\/li\u003e\n  \u003cli\u003eNon-flammable and non-corrosive for easier handling and storage\u003c\/li\u003e\n  \u003cli\u003eFollow label instructions for ventilation and protective equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho this is for: Corroseal 82320 is intended for boat owners, auto restorers, property maintenance crews, fabricators and DIYers who want an efficient way to stop active rust and prepare metal for painting without aggressive mechanical stripping. It’s particularly useful when time, cost, or access make sandblasting impractical and when a water-based, easier-to-handle product is preferred.\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: Do I need to remove all rust before using Corroseal?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. Remove loose flaky rust and contaminants, but Corroseal chemically converts remaining rust into a stable primer layer.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What cleanup is required after using this product?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Cleanup is simple—use soap and water on tools and spills because Corroseal is water-based and non-flammable.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Corroseal","offers":[{"title":"Default Title","offer_id":55168664830295,"sku":"B001CRFYG0","price":61.87,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/corroseal-82320-front-quart-label.jpg?v=1790411177","url":"https:\/\/britishgarage.co.uk\/products\/corroseal-water-based-rust-converter-metal-primer-1-qt-converts-rust-to-stable-black-paint-ready","provider":"British Garage","version":"1.0","type":"link"}
