Push the clip over the cable (it should be a tight fit) and hammer the nail into the wall or other surface. Place a clip approximately every 60 cm if the cable runs on a vertical or overhead surface. On horizontal surfaces a clip every 1 to 2,5 metres will suffice. For cable thicker than 16 mm outside diameter it is better to use saddles.
New concrete requires special treatment... New concrete must cure a minimum of 28 days before either tiling or putting a dressing onto the new concrete. There are two reasons for this: 1) As the concrete cures, drying and shrinkage cracks could occur. These cracks may eventually show up in tile or dressing applied before the 28 day curing period.
BS 5385-3:2007 Code of practice for the design and installation of ceramic floor tiles and mosaics, specifies that a screed shall be left for at least 3 weeks to dry prior to tiling. However, other documents specify longer periods and BS 8204 recommends 1 day per mm, for thicknesses up to 50 mm.
