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 is cured fully by twentyeight days. i think after this date one can apply the first coat of paint on top. Comment from parviz mohamadi, (2/10/2011, 2:44 PM) Surface preparation and conditions for painting of concrete surfaces can be found in SSPC-SP13 or NACE No. 6. That's right: All new concretes can be coated after 28 days, but the humidity of concrete and also soundness must be considered.
