Check your mirror is NOT safety backed. Safety backing film is either clear or white in colour and applied to the back of your mirror.
You do not need any backing to glue a mirror to a wall safely. You can use glue with foil backing if this was selected. Foil backing is a metallic colour and impossible to confuse with safety backing. However you must not use glue with safety backing as explained earlier. You may consider using foil backing if managing a site with independent contractors and you have concerns they may use the wrong adhesive. If you use the wrong adhesive on a mirror it could eat the paint and silver away.
Place the mirrors in a such way that the back painted side is up and facing you.
Take your mastic gun and apply lines of adhesive evenly sized and spaced about 10 cm apart across the face. IMPORTANT: Ensure the adhesive is not placed on the sandblasted area as this will show through as a shadow on the mirror face. We suggest leaving a minimum distance of 40mm from any pattern.
Once the mirror is covered with an appropriate amount of adhesive, safely lift and position the mirror into the desired location, applying firm even pressure to the mirror surface. The glue does not set immediately so you can maneuver the mirror once it has first been positioned onto the wall itself. However, try not to move it too much as the adhesive could spread and encroach onto the sandblasted area.
Once you are satisfied the mirror is in the correct position and if required is resting on a safe baton, we recommend holding the mirror for three minutes. After three minutes the mirror is safe to let go and will not come off the wall.
It does take 24 hours to dry and therefore do not remove the batons until this time has elapsed. Also ensure the room is at an ambient temperature as this helps the drying process.
Mirrors in wet areas or areas where there is potentially aggressive cleaning products being used need extra protection. Basically kitchen areas and bathrooms are areas where this additional protection is strongly advised. Simply take our neutral cure low modulus silicon and place a thin bead around the mirror creating a protective membrane around the back edge of the product. Our product is clear but other colours are available online if you wanted to make this a feature. To stress the bead need only be a few mm thick but in doing this your mirror will last for years without any chance of water or bleach like cleaning products attacking the edges over time and thus causing potential deterioration.
