## Abstract

A paint composition has incombustibility, flame resistance, heat shielding, heat insulation, water resistance and dew condensation prevention effects, thereby being effectively usable as a finishing, heat insulating, water resistant and incombustible material for buildings, and has a significantly thick film thickness even if applied only once, thereby being rapidly and conveniently usable when applied.

## Claims

### Claim 1

A paint composition comprising a main raw material and a liquid raw material in the weight ratio of 1:1,
wherein the main raw material includes:

expandable graphite at 20 to 40 wt %;
calcium carbonate (CaCO3) passed through a 325 mesh at 10 to 40 wt %;
a foaming agent at 1 to 2 wt %;
a fluidizing agent at 0.1 to 1 wt %;
a preservative at 0.1 to 1 wt %;
an antifoaming agent at 0.1 to 1 wt %;
hydroxymethyl cellulose or methyl cellulose having a viscosity of 5,000 to 30,000 cP at 0.01 to 0.5 wt %;
anhydrous gypsum at 10 wt % or less;
