Installation Precautions

・To ensure water resistance, be sure to add “Shirokabe Oil” during the mixing process.

・If the mixture is left to cure for more than one week, mix with powdered ginkgo grass to maintain applicability.

・If the roof clay shrinks significantly or contains too much moisture, cracks may appear on the surface.

・Cement may be added, but the decision regarding strength and color is at the discretion of the installer.

・During winter, efflorescence may occur and the color may change easily, so choose a warmer time of year for application whenever possible, and avoid application when temperatures are below 5°C.
