You can attach your Acrylic mirrors anywhere in or outside of your property. The mirrors come supplied with double sided sticky fixers which are normally quite adequate to fix them to most surfaces. Make sure surfaces are clean and dry before attaching. Please note: Certain areas may need further adhesion and sealing I.E. in bathrooms or rooms where moisture occurs or outside exposed to the elements. We suggest in these circumstances using a non-acitone, non-toxic and of course suitable for acrylic PVA adhesive - we would recommend either 'No More Nails'. (We cannot guarantee non marking of the mirrors if any other adhesive is used. To avoid moisture penetration it may be advisable to put a clear silicone sealer around the edges. This can be purchased from most DIY stores.
