These 1/4” thick pads are made from premium fibers, resins, and abrasives to provide consistent, multi-level surface blending when working with water-based urethane finishes on hardwood floors, with a very fine grade ideal for light abrasion between coats to ensure a smooth, even finish; designed for deburring, smoothing, cleaning, and general surface conditioning, they perform effectively between coats of both water-based and solvent-based finishes, while the 7” disc can be easily removed for use with an edger machine or used by hand for added versatility, making them a great choice for residential and institutional settings seeking efficient surface prep without the need for harsh or toxic chemical strippers.
