Gator 4242 Waterproof Sandpaper 180 Grit 9x11 in 25 Pack

Product Description

The GATOR 4242 is a waterproof abrasive sheet designed for wet sanding applications between coats of paint, sealer, varnish, and other surface finishes. Each sheet measures 9 inches x 11 inches and carries a 180 grit fine abrasive rating, making it well-suited for smoothing and leveling coats without cutting too aggressively into the surface. The resin bonding system resists moisture and outlasts standard glue-bond sandpaper, maintaining consistent cut and finish quality throughout the wet sanding process. Sold in a 25-sheet box, this product is used by painters, finishers, and general trades where surface prep quality directly affects the final coat appearance.

This sandpaper is appropriate for residential and commercial finishing work. Common applications include wet sanding primer, clear coat, lacquer, polyurethane, and varnish between application stages. The 180 grit level bridges the gap between aggressive material removal and final finish prep, making it a standard choice in multi-coat paint systems. Suitable for use on wood, metal, and composite surfaces where a fine intermediate cut is required before topcoating.

Installation Notes

Surface prep work with this product is typically performed by painters, finish carpenters, and general contractors. Always ensure the previous coat is fully cured per the coating manufacturer guidelines before wet sanding. Keep the surface and sheet lubricated with water or appropriate sanding fluid during wet sanding to prevent loading and maintain cut consistency. Dispose of used sheets and sanding slurry in accordance with local waste disposal regulations for the coating materials involved.
