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.
Re: Painting Fresh Concrete Surfaces. It is prefered to let the concrete cure for at least 28 days. If there are curing agents used, you can get on sooner. You can check out the Society for Protective Coatings SSPC-PA 7 Specification for Applying Thin Film Coatings to Concrete for further information.
