{"product_id":"watco-galvaprime","title":"Watco Galvaprime","description":"\u003cp\u003eWatco Galvaprime is a preparatory wash for galvanised and zinc surfaces before applying a compatible paint or coating. It treats the metal surface to improve adhesion, helping the following coating bond where untreated galvanising can be difficult to paint.\u003c\/p\u003e\n\u003cp\u003eThe single pack liquid is applied by brush and is designed for same-day preparation and overcoating. The treated surface turns black as the wash reacts, giving a visible indication of successful treatment on a properly cleaned substrate. Use Galvaprime as the preparation stage of a suitable coating system rather than as a decorative or weatherproof finish on its own.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePreparatory treatment for galvanised and zinc metal.\u003c\/li\u003e\n\u003cli\u003eBrush application with visible blackening of the treated surface.\u003c\/li\u003e\n\u003cli\u003eOvercoat the same day within the specified interval.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSurface Preparation\u003c\/h3\u003e\u003cp\u003eRemove oil, grease, dirt and excess rust before treatment. The surface must be sufficiently clean for the wash to react evenly. Check the intended topcoat's suitability for the substrate and the complete preparation system. Where heavy contamination prevents an even reaction, further cleaning or treatment is required rather than painting over the problem.\u003c\/p\u003e\u003ch3\u003eTechnical Data\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003ePack size\u003c\/th\u003e\n\u003ctd\u003e1L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eComposition\u003c\/th\u003e\n\u003ctd\u003eMixture of water, acids, preservatives and solvent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eApplication\u003c\/th\u003e\n\u003ctd\u003eBrush\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUse\u003c\/th\u003e\n\u003ctd\u003eInterior and exterior coating preparation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMinimum application temperature\u003c\/th\u003e\n\u003ctd\u003e4°C, following the technical sheet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShelf life\u003c\/th\u003e\n\u003ctd\u003e24 months unopened\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eCoverage\u003c\/h3\u003e\u003cp\u003eApproximately 20m² per litre.
