The invention provides a roof rigid waterproof construction method. The method comprises the following steps of S1, laying acrylic emulsion neat paste with a first preset thickness on the base surfaceof a roof panel; S2, laying acrylic emulsion mortar with a second preset thickness on the acrylic emulsion neat paste; and S3, sequentially laying two layers of acrylic emulsion neat paste with a third preset thickness on the acrylic emulsion mortar. According to the method, the acrylic emulsion paste is paved on the base surface of the roof panel, the acrylic emulsion paste belongs to a rigid waterproof material, not only has waterproof performance, but also can effectively improve the strength of the base surface of the roof panel, and the acrylic emulsion mortar is used as a protective layer of the acrylic emulsion paste, so that the waterproof leakproofness of the surface of the structure is further improved, two layers of pure acrylic emulsion mortar are laid on the acrylic emulsionmortar, the waterproof performance is effectively enhanced, the structure reinforcing effect is achieved, structure capillary holes are further sealed, the anti-permeability performance is improved, safety and reliability of the roof panel are guaranteed, the waterproof quality is improved, and the construction period can be shortened.

本发明提供了一种屋面刚性防水施工方法，该方法包括如下步骤：第一铺设步骤，在屋面板的基面上铺设具有第一预设厚度的丙乳净浆；第二铺设步骤，在丙乳净浆上铺设具有第二预设厚度的丙乳砂浆；第三铺设步骤，在丙乳砂浆上依次铺设两层具有第三预设厚度的丙乳净浆。本发明中，屋面板的基面上铺设丙乳净浆，该丙乳净浆属于刚性防水材料，不仅起到防水性能，而且能有效地提高屋面板基面的强度，采用丙乳砂浆作为丙乳净浆的保护层，进一步提高结构表面的防水密闭性，再在丙乳砂浆上铺设两层丙乳净浆，有效地增强了防水性能，并起到结构补强的作用，进一步封闭结构毛细孔，提高抗渗性能，保证了屋面板的安全可靠，提高了防水质量，还能缩短施工工期。
