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.
STEP 3. As the TSP reacts with the concrete, you are likely to notice a slight bubbling across the floor or surface. Let that bubbling continue coating the concrete for about 20 minutes, then hose it off, completely washing away the TSP. Let the surface dry for two days before painting.
