Balconies are exposed areas that often have little or no protection from the elements, and have the potential to be exposed to moisture for extended periods. New and existing balconies therefore need to be adequately protected to ensure that they do not become degraded from persistent infiltration. The entry of water into the balcony structure can be minimised by the application of a waterproofing membrane, and by sealing the surface of the tiles and grout with a water repellent product. Most modern balconies that are exposed will have an outlet built in that ensures any water that does find its way through the tiles or surface, does not settle and can run off.

Though techniques vary with particular products, the principles of waterproofing a balcony remain the same:

• remove old surface and any sealant and caulking
• wash surface thoroughly
• prime and caulk surface ensuring all cracks and holes are filled
• lay water proofing membrane
• apply polyurethane base coat
• allow to dry and cure
• the surface is ready for tiling or other surface application
