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.
What you describe as concrete is actually mortar. Sand and cement combine to mix mortar. (used ro setting bricks, for example) Sand and cement and an aggregate (small rocks) combine to make concrete. Any cementatious product reaches full cure in 29 days.Full cure being structurally safe, for example, that is when a tilt-up concrete wall can savely be lifted into place.oncrete cures essentially forever, although after 29 days, the rate of cure is dramatically reduced. For around home use, you are wondering how soon can you get onto the next phase of the project-whatever that project may be. It does depend on the project as to whether you will be safe or not.
