pH: Definition and measurement units. pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically.
sealing a cinder block wall. I just finished sealing the cinder block wall in our basement with Baer waterproofing paint. After the first coat I noticed little orange rust colored spots in one corner of the room. Nice fresh white coat of paint, little spots the size of peas on one wall.
It works for stage magicians, and it works for home decorators too. To redirect the eye from a cinder block wall, hang or prop oversized decorative panels in front of it. The panels cover much of the wall, they serve as artwork and, if they're striking enough, few will notice the wall behind them.or the cost of a few cans of paint and some applicators, you can make that ugly cinder block wall look like cut, fitted stone or brick. Cut stone is simplest look to achieve because you follow the existing grout lines.
