CONSTRUCTION METHOD FOR FLOOR STRUCTURE AND FLOOR STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a floor structure capable of forming a backing layer having high horizontal leveling property on an upper face of a non-water absorbing backing floor constituted by existing coated floor material finish or existing flooring material finish and a backing floor where the non-water absorbing backing floor constituted by existing coated floor material finish or existing flooring material finish remains partially in a short period of time and providing a coated floor material finish layer having high strength and high resistance to wear or a flooring material finish layer having satisfactory aesthetic appearance.

SOLUTION: This construction method for the floor structural body comprises: a process for providing a backing adjusting material layer on the upper face of the non-water absorbing backing floor by using any one of backing adjusting material selected from a polymer cement composition containing acrylic polymer emulsion (A) and primer containing acrylic polymer emulsion (B), and a process for providing a self-leveling material slurry hardened body layer on an upper face of the backing adjusting material layer by using a self-leveling material.
