A good care option is to carefully cover the concrete surface with foil. In this case, there is no need for additional wetting of the concrete, since moisture evaporating from the concrete is collected between the film and the concrete. Shelter of concrete should be done immediately after pouring, the connecting seams of the shelter should be glued or prevent air from entering the film in any other way.
If you carry out the shelter during the pouring of concrete or immediately after its completion, this will help to avoid the occurrence of cracks arising from plastic shrinkage of concrete. Unfortunately, it often happens that production requirements allow shelter only when cracks have already begun to occur. In this case, use a special tool for subsequent care of concrete. Also, the advantage of covering with a film is the protection of the fresh concrete surface from precipitation
