tesaÂ® Powerbond MIRROR is the ideal strong mounting tape for hanging mirrors and other flat objects. This double-sided self-adhesive mounting tape offers superior bonding power, even in humid surroundings such as bathrooms. It can hold mirrors of up to 70x70 cm and a thickness of up to 4 mm. You can forget about nails or screws. This unique mounting tape will securely attach your bathroom or wall mirrors without damaging any underlying tiles. Before mounting, check that your surface is sufficiently strong to hold the weight of your mirror. Then dry and clean the area using alcohol or silicone-free detergent. Apply the self-adhesive fixing tape to the back of the mirror in vertical strips. Remove the protective film and press firmly in place, taking care not to touch the adhesive surface. Hold for five seconds.
