Cautions

● Transport the product with care to avoid corner chipping and surface damage.
● Place the product flatly on a level plane near the installation place.
● As a precautionary measure, cover the products with a sheet, etc., to prevent exposure to direct sunlight and rain.
● Do Not weld nor fuse the installed product. If welding or fusing are inevitably required during the construction process, pay sufficient attention. Make sure to prepare a fireproof sheet and fire extinguisher, and perform welding or fusing in the presence of a supervisor.
● In exterior wall finishing, dry the concrete as much as possible before applying exterior walls, particularly if they are hardly breathable.
* Dry concrete until its moisture content becomes approximately 10% or less
