3M™ Centre Water Feed Disc Hand Pad Replacement Sponge, 82191, yellow, 7/8 in (22.2 mm), 10 per pack

The 3M™ Centre Water Feed Disc Hand Pad Replacement Sponge fits 3M™ Centre Water Feed Stikit™ or Hookit™ Hand Pads to keep the work surface damp without significant water run-off while sanding. This pad supplies the proper amount of water for wet sanding of plastics, primer surface, paint, and fibreglass. The water washes the sanding residue off the 3M™ Sanding disc which keeps the disc from loading.

The 3M™ Centre Water Feed Disc Hand Pad Replacement Sponge dispenses water to the 3M™ Centre Water Feed Disc Hand Pad which keeps the abrasive clean without significant run-off. This replacement part is an essential part of the 3M™ Centre Water Feed System which is a great system to use on primers and e-coat on automotive metal. The sponge holds water to supply in appropriate amounts to the surface, which flushes swarf from the sanding disc, and keeps the disc from loading. 3M Pad design dispenses precisely the right amount of water for wet sanding of plastics, primer surface, paint and fibreglass. Damp sanding minimizes airborne sanding residue, which is contained and wiped off of the coated surface before it settles into hard-to-reach areas. Potential defects and process time are both reduced, and residue does not become airborne and cause contamination during subsequent process steps (such as paint application). The water feed also helps keep the abrasive clean reducing loading and clogging, which extends the life of the abrasive and can help prevent defects from loaded or clogged discs.
