Each sheet measures 9 inches by 11 inches and is cut to 400 grit, making it well-suited for smooth finish sanding, light material removal, and surface preparation between coats. The flexible A-weight paper backing conforms to contoured surfaces, allowing consistent grit contact on curved or irregular profiles. This pack contains 25 sheets and is sold in a package of 10 packs per unit of measure. These sheets can be used wet or dry depending on application requirements.\u003c\/p\u003e\u003cp\u003eThese sanding sheets are used in finishing and surface prep applications involving paint, varnish, lacquer, and similar coatings. The 400 grit rating places them in the fine abrasive range, appropriate for final-stage sanding before topcoat application or for scuff-sanding between finish coats. They are commonly used by finishing tradespeople, painters, body shop technicians, and woodworking professionals. The flexible backing makes them practical for hand sanding curved trim, molding, and other contoured surfaces where rigid abrasives lose contact.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e400 grit silicon carbide abrasive for fine finish sanding on paint and varnish\u003c\/li\u003e\n\u003cli\u003eFlexible A-weight backing conforms to contoured and curved surfaces\u003c\/li\u003e\n\u003cli\u003eSuitable for both wet and dry sanding applications\u003c\/li\u003e\n\u003cli\u003eSheet size of 9 inches by 11 inches for versatile hand or block sanding use\u003c\/li\u003e\n\u003cli\u003e25 sheets per box, packaged for easy dispensing and jobsite use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose fine abrasive sanding sheet for use on painted surfaces, varnished wood, and similar finish coatings in both wet and dry sanding applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThese abrasive sheets are a consumable finishing supply and do not require tool installation.
