3M Hookit Wetordry Paper Sheet 401Q features extra-fast cutting silicon carbide on a lightweight paper backing to provide you with superior finishing for both wet and dry applications on a variety of substrates. The 3M Hookit attachment lets you easily attach, remove and replace the abrasive while you work.

Wetordry Waterproof Backing
3M Hookit Wetordry Paper Sheet 401Q is backed with a proprietary durable waterproof paper backing that supports both wet and dry applications. Lighter weight than cloth, and smooth rather than textured, paper backing is preferable for lighter applications such as finishing and paint prep. At the same time, many such applications produce a significant amount of dust, clogging the abrasive points and creating an inferior work environment. These effects can be minimized by sanding with water.

Used with water, 3M Hookit Wetordry Paper Sheet 401Q enables the user to rinse areas of the workpiece and the sheet during use to prevent dust and debris from clogging the points of the abrasive, while producing a faster cut at the same time. These versatile discs are ideal on surfaces that tend to generate a lot of dust, such as paint, primer, and wood, and can also be used dry for finishing metal and gel coats.

Hookit Attachment Makes Changes Easy
3M offers a complete line of hook-and-loop style 3M Hookit abrasives for work spaces where adhesive-backed abrasives may become contaminated by dust or dirt. They are often used in applications where a 3M Stikit product may be too aggressive, as Hookit products tend to leave finer finishes than adhesive-backed abrasives. Hookit abrasives can be removed cleanly and easily, and can be re-used again and again for the extent of the abrasive life.
