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.
Time Before Grouting. Drying time varies with ambient air temperature, humidity and moisture content of the mortar when applied. In general, mortar must set at least 24 to 48 hours before grouting. Apply mortar when the ambient air temperature is between 50 and 100 degrees Fahrenheit.Ideally, temperatures should not exceed this range for at least 72 hours after application.ven when mortar appears dry on the outside edges of the tile, it may not have fully cured beneath the tile surface. Allowing proper time for the mortar to cure before grouting will ensure your tiled surface will last for at least decades.
