An abrasive holder has a moulded base for a pad of a closed cell foam or cork. The support has a handle for finger and thumb operation. The pad is glued to the base and supports a peel-off piece of abrasive cloth or paper having an adhesive face. The holder is for fine work or working in contact with glass. The pad prevents scratching while permitting surface preparation up to the glass border. Acrylic emulsion adhesives and foam densities of 30-200 kg+544 m3 are disclosed.
