NOTES:
- Chemically active means that the ingredients chemically bond to calcium
from the fresh cement paste.
- Viscosity measured in centipoises at room temperature. For comparison,
water is 1 cps and 30 weight motor oil is 200 cps. Spray tips don't spray well
above 60 cps.
- When applied at a film thickness of 0.001 inch or less.
- This means without cleaning off the release agent, though cleaning may be
required to remove other foreign matter.
