摘要:
A construction method of multicoating waterproof layer using resistance type insulation and reflection type protection coating material are provided to archive the water proofing, insulation and heating difference effect in one construction at the same time. The first step(P1) is to apply the base concrete(C) on the primer(10) by using a resistance type thermal insulation material and a reflection type protective coating material. The second step(P2) is to cover the primer layer with a porous insulating sheet. The third step(P3) is to fix the porous insulating sheet to the connection part of the porosity insulating sheetby using an adhesive tape(30). The fourth step(P4) is to apply 1-liquid type polyurethane coating material to the porous insulating sheet. The fifth step(P5) is to apply the 2-liquid type polyurethane coating material(70) to the porous insulating sheet. The sixth step(P6) is to spread a resistance type thermal insulation material(50) on the polyurethanes film material layer. The seventh step(P7) is to apply the 2-liquid type polyurethane coating material having the viscosity of 5,000~13,000 CP. The eighth step(P8) is to apply the thermal barrier top coat composition(80) for waterproof material mixed with a hardener.
