Installation Precautions

・Be sure to add “Shirokabe Oil” when applying the mixture to exterior walls or areas exposed to water.

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

・Always apply “Shirokabe Sealer” to substrates that are highly absorbent of water.

・Use a metal trowel as much as possible for troweling; use a plastic trowel only for finishing.

・Since efflorescence is more likely to occur in winter, keep the area as warm as possible and avoid application when temperatures are below 5°C.
