Norton sanding blocks provide better control and a more consistent surface finish versus using sandpaper alone. Rubber， cork and foam blocks are available as well as those with clip fixings to hold the abrasive paper securely. Norton sanding blocks are ergonomic and make the sanding process more comfortable. Ideal for use with abrasive sheets and rolls which can be torn to size for DIY and professional use on a number of surfaces including wood (bare， painted， varnished) plaster and metal (depending on the abrasive paper used).
