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.
Best Answer: Concrete's strength is normally expected to reach its design strength in 28 days if it has been cured properly. Curing properly involves keeping the concrete moistened with water for the duration of the curing period or by sealing the surface with a spray-on concrete cure and seal product.he full design loadings on the slab should be avoided for 28 days. The previous durations apply to normal and concrete placements as large as say 3 or 4' thick or more, mass concrete placements continue to cure for an extended period due to the heat of hydration and moisture content issues.
