What is the difference between naturally and artificially alkaline water? When measured in drinking water, an alkaline pH can be a result of either natural or unnatural conditions in the water. Thus when comparing two waters, each with a pH of 9.5, one can be healthful while the other causes side effects. Water ionizers split apart water molecules with electricity to artificially create alkaline water.
Re: Painting Fresh Concrete Surfaces. We have to paint below ground concrete surfaces with Epoxy PAINT or Bituminous paint. The engineers says we can paint only after 30 days. What is the actual time gap required to paint on new concrete surfaces.
Wait at the very minimum 4 hours for the paint to be completely surface dry. Then to be to be sure not to damage the new paint work wait for 24 hours if you can.   Lo â¦ ts of factors to consider. The humidity is a big factor, as well as temperature. You need to have good ventilation.
