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.
1- How long should we let the tile and thinset sit before grouting? If you are using basic 12 x 12 porcelain field tile and bagged thinset mortar, wait 8 to 12 hours before grouting. - How long should we let the grout dry? You said you used a non-sanded grout, and if you got it from us, it should look something like this.... Polyblend non-sanded grout typically dries in 6-7 hours. The thinner the tile spacers you put in, the faster it will take the grout to dry.
