Burning off paint, varnish and lacker

Abstract

A specially designed oxy-acetylene blow-pipe of multiple tips was used to remove efficiently the paint, varnish and lacker coated on the metal surface of structures. These coatings were burned off by the oxygen rich flame and then easily removed by scraping with the tool. Various lackers and varnishes were easily removed. Many kinds of oil paints were removed as well, but some pigments contained-namely, ultramarine, carbon black and chrome yellow-hindered perfect burning. They are hard to remove. Papers pasted on the wooden plate burned off quickly. If uhe surface of such plate was saturated with water, carbonization of it did not occur. © 1951, JAPAN WELDING SOCIETY. All rights reserved.
