Fitting A Mirror



  • Clean face and back of mirrors prior to fitting.
  • The protective coating (specialised paint) does have limitations and care should be taken not to penetrate the coating. Ensure that the coating cannot be attacked by chemical and water action from the back or paint surface.
  • Air space should be provided to allow the mirror to ‘breath’. A minimum 3mm gap should be allowed. This is particularly important where humid conditions are prevalent. Mortar, concrete, cement screed and plaster contain alkali which will reduce the life of the mirror.
  • Mirrors below one square metre may be fitted with mastics or mirror backing double-sided adhesive tapes. Tapes must be fixed vertically. Mirrors above one square metre must be fitted to the ceiling or must be fitted by mechanical means.
  • When fitting sectional mirrors glass-to-glass contact should be avoided. Adjacent mirrors should have a clearance of 0.8mm.
  • Spacing washers and insulating sleeves should be of an inert material, e.g. nylon or polyethylene.
  • Mastics, mirror tapes, adhesives silicones, etc. used in fitting mirrors should be compatible with the protective backing. PFG Mirror technical assistance of choice of products.
  • The edges of mirrors should not be sealed with tile grouting, cement silicone or similar materials.
  • When using proprietary brands of cleaning fluids to not allow overspill along the mirror edges.




  • Ensure that the correct fitment procedures have been followed.
  • It is recommended to clean the mirror using a chamois leather dipped in warm water and methylated spirits.
  • Do not use acidic or alkaline (armonia based) cleaners, as they attack the baking paint.
  • Do not use an abrasive cleaner such as steel wool on the face of the mirror, as it scratches the glass.
  • Do not apply cleaning fluid directly on to the face of the mirror as it could spill over the edge and onto the back of the mirror.
  • Apply cleaning solution to a cloth and the wipe the mirror.
