abrasive sponge marketed by Finishing Aids and Tools, Ltd., Chandos House, Buckingham Gate, London, S.W.!, makes it flexible and resilient so that curved, flat and profiled surfaces can be dealt with. Little heat is said to be generated thus eliminating the danger of discoloration and blistering.
No coolants or lubricants are necessary and, because of the structure of the sponge and the type of bonding, only light and infrequent dressing is required.
The Artifex abrasive sponge is available in four grades; soft, medium hard, hard, extra hard, and in a complete range of grain sizes with wheels up to 16-in. diameter and 4-in. thick. 24 shades which can all be intermixed to provide a variety of effects. The material is said to be touch dry in two hours and hard dry in four to six hours, and covering capacity 90 to 135 sq. ft. per gal.
