The finish coat should only be applied in warm weather. Do not apply impregnation or varnish on hot concrete, under direct sunlight. In this case, the coating "sintered" as in a frying pan, not penetrating deep into the concrete, forming a "yellow crust.

It is not recommended to varnish in cool weather, before winter, when the air temperature 5-7 ° C and at night is "frosting," in which case the lacquer can freeze and peel off (peel off). Therefore, in the fall, it is better to cover in 1 layer of impregnation, and in the spring when the weather is warm, wash and dry the surface and cover with 2 coats of varnish.

Detachment of the release agent is possible during the cold season when working with purchased concrete. During this period, RBU change the composition of the concrete and switch to an antifreeze additive. The chemical composition of the release agent is not compatible with most of the antifreeze additives, so in 99% of cases there will be delamination of the release agent with part of the concrete. It is best not to do any work during the cold season.
