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.
Concrete first must be scoured clean with a concrete cleaning solution, a scrub brush or a cleaning machine, then allowed to dry before any etching takes place. Never clean a new concrete pad until at least one month of curing time has been allowed at minimum. After all the water has been removed, the pad should have at least 48 hours of drying time before you apply any etching to the surface. If the weather is particularly humid, wait up to 72 hours for best results. There are numerous types of etching materials available for use with concrete, but as a general rule, they only need 15 to 30 minutes of time on the surface of the concrete to work their way down through the initial layer and etch the surface.
