A construction method of a floor finishing layer using inorganic marble pattern chips is provided to prevent separation by using materials having the same thermal expansion coefficient to a concrete foundation and to offer the stability of construction by having high binding strength, and to create natural marble patterns on the surface of a floor by preventing the whitening phenomenon caused by laitance after construction. A construction method of a floor finishing layer using inorganic marble pattern chips, for constructing an inorganic floor finishing layer by placing a flame-resistance primer layer, a base coat layer and a top coat layer on the upper part of a concrete foundation layer in order, comprises the steps of constructing a primer layer on a concrete foundation layer(S501), mixing inorganic power and water in a ratio of 2~5 to 1 and stirring for at least 3~5 minutes at room temperature(S502), forming the stirred composition on the primer layer(S503), leveling the surface of the composition using a surface leveling device, and constructing a base coat layer to a thickness of 0.5~10mm(S504), spreading flame-resistant inorganic marble pattern chips unevenly(S505) and curing for at least 12~24 hours at room temperature, grinding the surface of marble pattern chips risen to the base coat layer(S506), and forming a coating layer on the base coat layer with an inorganic coating material having the specific gravity of 0.9~1.1g/cm^3 and constructing a top coat layer(S507). |
