Curing New Concrete. New concrete is very alkaline with a pH of 12 to 14. It also has high moisture content. These characteristics will interfere with paint adhesion, leading to bubbling and peeling. Allowing the new concrete to cure for at least 30 days can reduce the alkalinity and moisture content to levels low enough for the concrete to take paint. But it can take as long as 90 days before new concrete has cured enough for painting, depending on climate and weather.
With less than one year of experience, a dental hygienist can expect to earn at least $12.38 an hour. This works out to almost $26,000 a year. On the high side, hygienists can earn a starting wage of $34.88 an hour, or just over $72,000 a year â a respectable salary for almost any professional fresh to the field.he median wage â or âmidpointâ salary for this occupation â was $69,280 a year, which means that half of all hygienists earn this salary or more a year. But neither of these figures account for experience. As with any job, a dental hygienist makes less when starting in the industry.
Salary Outlook. Hygienists make comfortable salaries, especially considering that more than half of them work part time. In 2013, their median salary was $71,110. The best-paid earned about $96,690, and the bottom 10 percent earned $47,880.70,700. With an average salary of $71,530 in 2013, dental hygienists earn salaries that compare well to other health care jobs. However, dental assistants ($35,640) and clinical laboratory technicians ($40,240) generally make about half as much money.
