Ease of installation It can be easily and quickly attached to narrow corners, uneven surfaces, etc. When attaching, please ensure the surface is clean, dry, oil-free, and dust-free. Cut to a certain size, peel off the shielding film, and press firmly onto the surface to adhere it to the base. (Note: Viscosity may decrease if the temperature is too low, so we recommend installation at 13°C or higher.) Notes ・ Please do not remove immediately after application. It takes about a week for it to fully adhere to the base and reach its optimal state.
