There are two common reasons why your sticker might not feel tacky or sticky after application:Water method application: If you've used the water method to apply your sticker, it's normal for the sticker to not feel sticky while it's wet. In this case, you need to ensure all the water is pushed out from underneath the sticker. Once the water is removed, the sticker should adhere properly to the surface.Residual isopropyl alcohol: If you've cleaned the surface with isopropyl alcohol before applying the sticker and the alcohol has not completely dried up, it could affect the sticker's adhesiveness. In such cases, leave the sticker with the sticky side exposed to the air until it's completely dry. Once dry, it should regain its original tackiness.For detailed application instructions and tips, please refer to our blog post: How to Apply Suction Sticker to Stokke Tripp Trapp Tray
