RETAINING METHOD OF STRENGTH AND HARDNESS BY PREVENTING INCOMPLETE HYDRATION REACTION CAUSED BY ATMOSPHERIC TEMPERATURE AND QUALITY OF BASE MATERIAL WITH WATER BASE PAINT AND COVERING MATERIAL CONTAINING CEMENT SYSTEM INORGANIC SEALANT AS INDISPENSABLE COMPONENT

摘要

PROBLEM TO BE SOLVED: To retain a hardness and a strength of a surface and to prevent a deterioration phenomenon at the time of applying a painting and covering to a base material having a high water-absorbing/hygroscopic ability.;SOLUTION: A water base paint and a water base covering material containing a cement system inorganic sealant as an indispensable component and preventing a ductility and a crack of a coating film surface caused by an incomplete hydration reaction generated by a water-absorbing/hygroscopic performance of a base material are coated. Thereafter, the ductility and the crack on the coating film surface are prevented by adjusting a moisture content replenishment onto a surface of the coating film.;COPYRIGHT: (C)2002,JPO
