Description of the Related Art In modern architecture, the natural texture or appearance of the exposed concrete material itself is preferred to enhance the design value of the building. However, the surface of the exposed concrete inevitably has imperfections, burrows, pinholes, and other defects due to the shape of the inner surface of the formwork due to its construction method, which impairs the aesthetics and also the surface of the concrete. The water absorption of is non-uniform. Therefore, it is natural to repair the surface of such exposed concrete. However, even with such repair, it is impossible to eliminate surface defects and make the surface layer uniform in water absorption.

【００４３】図１および図２に示す結果から明らかな様
に、本発明による仕上げ剤は、１５００時間にも及ぶ促
進耐候性試験においても、耐候性には変化が認められ
ず、且つ撥水性にも変化は認められない。As is clear from the results shown in FIGS. 1 and 2, the finish according to the present invention showed no change in the weather resistance even in the accelerated weather resistance test for 1500 hours, and showed no water repellency. However, no change is observed.
【００４４】比較参考例１ 実施例１で使用したと同様のアクリルシリコン樹脂防水
剤をそのまま使用する以外は参考例１と同様にして打放
しコンクリートの表面塗装を行なった。Comparative Reference Example 1 Exposed concrete was surface-coated in the same manner as in Reference Example 1 except that the same acrylic silicone resin waterproofing agent used in Example 1 was used as it was.
【００４５】図１および図２に示す様に、フッ素化芳香
