3M Company 99419NA 600 Grit Wet or Dry Sandpaper 25ct

Product Description

The 3M COMPANY 99419NA is a silicon carbide wet or dry sanding sheet designed for fine finishing work on paint, varnish, and similar coatings. Each sheet measures 9 inches x 11 inches and is cut from a flexible A-weight backing that conforms to contoured surfaces without tearing. At 600 grit, these sheets are suited for final smoothing passes and surface prep before topcoats. The sheets can be used dry or with water, which helps reduce clogging and extend sheet life. Licensed HVAC, painting, and finishing professionals as well as experienced DIYers use these sheets for detail and prep work.

These sanding sheets are a fit for surface finishing applications where a fine, consistent scratch pattern is required before applying paint, varnish, lacquer, or clear coat. The flexible A-weight backing makes them practical for curved or irregular surfaces that flat sanding blocks cannot follow closely. Sheets are packaged 25 per box, and the package uses a tri-lingual die-cut design for straightforward identification at the point of purchase or in a job-site supply storage area.
