ABSTRACT:
A slaked lime-based coating material composition which gives a consideration to sick house syndrome is a powdery composition obtained by mixing either calcium hydroxide or a calcium hydroxide/magnesium hydroxide mixture with one or more carrageenans comprising a six-membered-ring galactose skeleton and bonded thereto in equatorial conformation a sulfate group(—OSO3−) and a hydroxyl group(—OH) and which is kneaded together with water at time of use, or a slaked lime-based plastering material composition which gives a consideration to sick house syndrome is a pasty slaked lime-based coating material composition obtained by mixing either calcium hydroxide or a calcium hydroxide/magnesium hydroxide mixture with one or more carrageenans comprising a six-membered-ring galactose skeleton and bonded thereto in equatorial conformation a sulfate group(—OSO3−) and a hydroxyl group(—OH), and which is kneaded together with water in advance.
