tesa Powerbond Mirror has been specially developed to give a reliable, permanent hold on hard and even indoor surfaces. That includes humid rooms like bathrooms and kitchens. How to use – step by step Use some alcohol or silicone-free window cleaner and a clean cloth to give your surface a good clean. Getting rid of dirt or grease will help to give an optimal hold. The surface should be dry too. Apply tesa Powerbond Mirror in vertical strips to the rougher surface before pressing down firmly across the entire surface for at least 5 seconds. This activates the Powerbond Technology. Because the top of the hanging area will have to bear the most weight, put some more lengths of tape here. Remove the protective foil from the tape, then press your item into its position. Finally, press down all over the item for another 5 seconds. This will give as strong a bond as possible.
