Gator 4237 Waterproof Sandpaper 1500 Grit 9x11 in 25 Pack

Product Description

The GATOR 4237 is a waterproof abrasive sandpaper sheet designed for wet sanding applications in finishing work. Each sheet measures 9 inches x 11 inches and carries a 1500 grit rating, placing it in the mirror-fine range for ultra-smooth surface preparation. The sheets feature a resin bond coating that holds the abrasive mineral longer than standard glue-bond sandpaper, extending usable life across multiple passes. Sold in boxes of 25 sheets, the 4237 is a practical stock item for body shops, finish carpenters, and trade painters who cycle through fine-grit abrasives regularly.

This sandpaper is formulated for wet sanding between coats of paint, sealer, varnish, lacquer, and other liquid-applied finishes. The waterproof backing holds up to water and compatible sanding lubricants without delaminating or tearing mid-pass. At 1500 grit, it removes minor surface imperfections and levels the finish film without cutting through to the substrate. It is suited for both residential finish work and light automotive or marine coating applications where a smooth, flat surface between coats is required.

Key Features

• 1500 grit mirror-fine rating for ultra-smooth wet sanding between finish coats
• Waterproof backing withstands water and sanding lubricants without delaminating
• Resin bond coating outlasts standard glue-bond abrasive sheets
• Full 9 inches x 11 inches sheet size for broad coverage per pass
• 25 sheets per box for consistent job-site supply

Compatibility

Designed for wet sanding use with paints, sealers, varnishes, lacquers, and other liquid-applied topcoats on wood, metal, and primed surfaces.

Installation Notes

Use with water or an appropriate sanding lubricant to keep the abrasive surface clear and reduce loading. Fold or cut sheets to fit a sanding block for consistent, flat pressure across the work surface. Allow each coat of finish to fully cure to the manufacturer-specified dry time before sanding. Dispose of used sheets and rinse the work area to remove abrasive slurry before applying the next coat.
