Many people who use creatine gain weight. This is because creatine causes the muscles to hold water, not because it actually builds muscle. There is some concern that combining creatine with caffeine and the herb ephedra (also called Ma Huang) might increase the chance of having serious side effects such as stroke.
Concrete retained in forms or covered with insulation seldom loses enough moisture at 40 to 55 degrees Fahrenheit) to impair curing. However, drying from low wintertime humidities and heaters used in enclosures is a concern.
Cure - Concrete must be cured prior to coating application. Cured is defined as concrete poured and aged at a material temperature of at least 75Â°F for at least 30 days. The pH of the surface should be between 6 and 9. Moisture - (Reference ASTM D4263) Concrete must be free of moisture as much as possible (moisture seldom drops below 15% in concrete).
