How it works?
To put with the roller (a back part of a form) or a dusting (concrete for a paving, instant division, etc.) the product preventing curing of cement on depth from 1 to many millimeters (depending on influence force).
Approximately in 30 minutes, alkalinity of concrete helps active particles of a superficial delay mechanism to move to concrete thanks to availability of free water, it occurs during 1 h - 1 h is 30 min. old.
Next day we wash away cold water under pressure this thin concrete layer which did not harden. Concrete stay duration in shape is also not a problem. Products can be left 3 or 4 days in shape without change of appearance of a surface.
