Abstract

This research was carried out focusing on the urgent treatment and related studies for paint scribbling on Samjeondobi Monument (Historic Sites No. 101) in 2007. Before the preliminary test, the paint lacquer used on the surface of Samjeondobi Monument was analyzed. The paint lacquer turned out to be the paint lacquer spray composed of $Pb_3O_4$ used for the red pigment in the market. It was proved that the poultice used with the organic solvent was the best way to remove the paint pollutants following the preliminary test for the removal of paint pollutants which was performed with various removal methods by the laser, etc. However, the removing the paint pollutants was found in difficulty in contrast to the preliminary tests because the paint on the spot was hardened so rapidly over time that there was difference from the situation of the laboratory. For that problem, the poultice method with ethylene dichloride of main component from Remover (goods in the market) was the most efficient, therefore the pollutants were removed with the solution of alkyds resin and nitrocellulose and the rest part was removed by the $Laponite^{(R)}$ RD.
