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.
Concrete first must be scoured clean with a concrete cleaning solution, a scrub brush or a cleaning machine, then allowed to dry before any etching takes place. Never clean a new concrete pad until at least one month of curing time has been allowed at minimum. After all the water has been removed, the pad should have at least 48 hours of drying time before you apply any etching to the surface. If the weather is particularly humid, wait up to 72 hours for best results. There are numerous types of etching materials available for use with concrete, but as a general rule, they only need 15 to 30 minutes of time on the surface of the concrete to work their way down through the initial layer and etch the surface.
