Compatibility with siding clear paint for repair and sealing material

Abstract

The present when we have begun to handle ceramic siding clear paint for repair from each paint maker, it is listed in the catalogue of each maker to beat it after the clear paint, because the joint sealing may cause a crack and weak adherent coating and pollution by the painting. We guessed that weatherability improved by protecting the sealing materials in clear coating like ceramic siding. We put 15 kinds of sealing materials and 11 kinds of clear paint for repair together and did outdoor exposure. We arranged the result that evaluated outdoor exposure one month later and three months later and six months later and 12 months later, and we evaluated the tendency by the combination.
