Mirror Demisters - Frequently Asked Questions
Why does a mirror mist up?
Mist on bathroom mirrors is caused by condensation from the warm moist air created during a shower or bath. Simply by raising the surface temperature of the glass this will prevent condensation forming.
How easy are demisters to install?
Very easy - simply peel off the backing paper and press the self-adhesive coating to the back of the mirror, taking care to position correctly and avoid any air bubbles. The wire is then connected up by the electrician to a switch.
How thick are the demisters?
The demister is less than 1mm thick, however an allowance may need to be made for the small connection block (5mm) if the demister is being bonded to the wall with no gap.
What size demister should I use?
You do not need to cover all of the mirror, but simply the main central area that you use after a shower. For example, if your mirror was 2000mm wide, 800mm high, then our largests off the shelf size demister 1524mm x 524mm would be perfect if located centrally on the mirror. For very large mirrors or those which span a double vanity, we suggest you use 2 demister pads..
Can I cut my demister pad?
No - the demister pad is double insulated and factory tested and sealed. If you cut or damage the demister it will no longer be safe to use.
How do I fix the mirror to the wall?
A mirror fitted with a demister can be hung onto fixing clips or bonded directly to the wall. Note, if binding directly to the wall you will need to ensure that a small area is recessed to correspond with the connection block that attaches the wire to the demister so it sits flush.
How long does it take to demist a mirror?
It only takes a few minites for the demister to heat up the mirror sufficiently to prevent mist from forming, so you should turn it on before running the bath or shower so the mirror will remain clear. If you turn it on afterwards, it should only take 2-5 minutes to clear.
What is the warranty period?
We offer a 5 year warranty on the mirror demisters.
