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.
The advantage to sealing new concrete with a cure and seal is that the concrete does not have time to get dirty or stained. If a cure and seal is not being used, then you should allow the concrete to cure for 2-4 weeks. The industry standard is 28 days but that depends on the climate and mix of concrete. It is important to wait and not to seal new concrete too soon. Trapping moisture in the surface will likely lead to a premature failure of the sealer.
