How To Install Mirrors With Adhesive

Step 1 - Check your wall and specification

Ensure your wall is clean and dust free. You may wish to hire an electrician to remove and refit power sockets if required. Only after the power to your electrical sockets and appliances have been switched off should you start your installation. 

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.  

Step 2 - What you need

You require a tape measure, pencil, mastic gun, mirror adhesive, stanley blade, 3mm tile spacers if concerned with expansion gaps, low modulus neutral cure silicone if wanting to seal and protect your mirror and finally you may possibly consider glass suckers. Most people do not use glass suckers but these are available in our mirror extras section /mirror-extras/

If you do not use our mirror adhesive please ensure it clearly states MIRROR ADHESIVE on the tube and do not listen to anyone else's advice as certain aggressive glues such as no nails will eat into the back of the mirror - only trust the tube! If using our adhesive one tube will hang 22kgs of mirror onto a flat surface.

Finally you may need to secure and prepare a baton for the bottom of the mirrors. The adhesive takes 24 hours to fully cure and if building a wall of mirrors if you do not fix batons you may find that a few mirrors have slipped a few mm during the drying process and it will look terrible. The batons are only there to stop slippage and not to support the mirrors. People use skirting board for a baton and various ingenious support methods - how you prepare this is up to you but we certainly recommend this for any mirrors weighing more than 15kgs.

Step 3 - Installation

Place the mirrors in a such way that the back painted side is up and facing you.  

Then place your adhesive into your mastic gun and use the stanley blade to cut the top off.

Apply lines of adhesive evenly sized and spaced about 10 cm apart across the entire face. Be careful not to go too close to the edge with the adhesive as it will smear and spread when it is fixed to the wall and you do not want any seeping out a side as this would require cleaning and additional work.

Once the mirror is covered with an appropriate amount of adhesive safely lift and position the mirror into the desired location. The glue does not set immediately so you can maneuver the mirror once it has first been positioned onto the wall itself.

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.  

If your mirrors require allowance for expansion gaps use the 3mm tile spacers to maintain this and you may need to increase or decrease these gaps to ensure the joins are neat depending on how accurately you have measured, and allowing for manufacturing tolerances.

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.
