How often should I change my plaster? Usually, wound dressings and plasters should be changed daily for hygienic reasons. If you use an advanced plaster that provides Moist wound healing conditions, it is recommended to leave it in place for up to two days or more in order to not interrupt the healing process.

In hot weather conditions, saw cutting may start as soon as four hours after the concrete is poured. In cooler weather, sawing may not start for 12 hours after pouring. 1 The best way to determine whether the slab is ready is to make trial cuts to check for raveling.

Joints should be sawed as soon as the concrete will withstand the energy of sawing without raveling or dislodging aggregate particles. For most concrete mixtures, this means sawing should be completed within the first six to 18 hours and never delayed more than 24 hours.

Concrete which is moist cured for 7 days is about 50% stronger than uncured concrete. Water curing can be done after the slab pour by building dams with soil around the house and flooding the slab. The enclosed area is continually flooded with water. Ideally, the slab could be water cured for 7 days.

Rain is a good thing.....as long as it is not heavy rain in the first 24hrs (which can causes pitting... little tiny surface dents). After around 24hrs, the top of the concrete will set and the slab will start to cure. Once it is curing, it is much better to be rained on then baked in hot sun.

After concrete is placed, the concrete increases in strength very quickly for a period of 3-7 days. Concrete which is moist cured for 7 days is about 50% stronger than uncured concrete. Water curing can be done after the slab pour by building dams with soil around the house and flooding the slab.

In general, the foundation color should be the same or darker than the siding color.

All concrete will shrink slightly as it dries and, when it's set, will expand or contract depending on the ambient temperature. To prevent cracks from forming, concrete expansion joints should be incorporated to allow for movement, particularly in slabs with a surface area exceeding 6m2.

“The minimum depth of sawcut using a wet conventional saw should be the greater of at least 1/4 of the slab depth or 1 in. (25 mm). The minimum depth of sawcut using an early-entry dry-cut saw should be 1 in. ... Some slab designers require cutting the slab the following day to 1/4 of the slab depth to deepen the 1 in.

The typical life expectancy of a good-quality metal roof is up to 70 years, far exceeding that of concrete tiles, which generally last for 50 years or so, with time-consuming regular maintenance and repair.
