{"product_id":"wet-dry-abrasive-sandpaper-sheets-230x280mm","title":"Wet \u0026 Dry Abrasive Sandpaper Sheets 230mm x 280mm (100-1500 Grit)","description":"\u003cp\u003e\u003cstrong\u003eWet \u0026amp; dry abrasive sandpaper sheets, 230 x 280mm (9.06 x 11.02in), running the full grit range from 100 (coarse) up to 1500 (ultra-fine)\u003c\/strong\u003e, with a waterproof coating that supports both traditional dry sanding and lubricated wet sanding on paint, lacquer, filler and plastic surfaces. The sheets are supplied across eight grit grades (100, 240, 360, 400, 600, 800, 1000 and 1500), covering everything from initial stock removal through to an ultra-fine finishing pass. Particle sizes across the range follow the FEPA P-grade classification (ISO 6344) for coated abrasives, the standard reference most trade and hobbyist sandpaper is graded against.\u003c\/p\u003e\n\u003cp\u003eThe waterproof coating keeps the abrasive grain firmly bonded to the sheet when it's used with water or a sanding lubricant, so the paper resists breaking down and clogging far better than an ordinary dry-only sandpaper would under the same conditions, a real advantage when working through several grades in sequence on the same panel. The backing itself also changes across the range to suit the job: the coarsest 100 grit sheet uses a stronger, stiffer backing built for aggressive stock removal, while the 240 grit sheet and everything finer than it uses a softer, more flexible backing that conforms closely to curved or contoured panels, which is what makes it suited to hand-flatting shaped bodywork by eye rather than only flat surfaces. Because the coating and backing are matched to the job across the whole range, the same waterproof sheet format carries a refinishing job through every stage, from first cut to final polish, simply by swapping grit rather than switching to a different type of abrasive.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSheet
