Hi after some advice I used mirror mate on a large mirror I had for the gym garage and attached it to some mdf that I cut 140x140 and painted white.

The mirror has been hung on the garage wall for about a year but I've noticed it's got damp in the top right corner and has a little mold on it,it is attached to the outside wall.

The mirrors also started to come away at the bottom corners not sure if it's the mdf or mirror.

Any idea on how to fix this don't fancy going into the garage one morning and finding it in pieces :cry:

Simple, the mdf hardboard has got damp and has bowed - the mirror hasn't moved with it as it can't bow like timber hence its coming away, eventually it will probably fall of completely, if you must use a board I'd replace the thin mdf with something thicker like 3/4", fix it back to the wall in multiple places and then bond the mirror onto it maybe even using those concealed support brackets linked to above, however if you were to just use the brackets on their own then its a must that you use a mirror backing film to the back of the glass, if it breaks and is just held with brackets then without film its going everywhere including your arms and legs

Thanks tbh this is what I was thinking taking it down reapplying mirror glue leaving some weights on top over night then fixing more fittings where the woods bowing.

I'm not using them fittings above still have nightmares using them with them ikea mirrors :LOL:
 
Just took it off the wall the backs not looking great.

Would it be worth putting wooden batons on the wall first so the backs not against the brick? Was thinking about wiping it down with some bleach first.
