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.
Report Abuse. concrete will cure in about 24 to 48 hours. but for it to fully cure it take alot longer then that. the hoover bridge is still getting stronger because it's still curing.Mr. Anderson Â· 8 years ago.est Answer: It really depends on how wet the ground is and the ground temperature. As a rule you should wait at least a week before starting a construction project on new concrete, 30 days is even better.
