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.
Typical concrete takes 28 days (4 weeks) to cure. Prior to the 28 days concrete still has moisture in it that weakens the strength of the concrete. If you seal it prior to 28 â¦ days there is a chance you will be sealing in some of that moisture and hence weakening the integrity of the concrete.hat depends on the concrete, as well as weather conditions, and the load the concrete would be subjected to. Concrete gains strength over time and the usual benchmarks are 7 â¦ days, and 28 days. At 28 days concrete has usually cured to nearly its maximum strength.
