In order to be able to guarantee a permanent sealing result, after the previously exposed, cleaned and open-pored wall, the EUROKRISTALL active substance is first built up in a depot, consisting of 3 to 4 mineral functional layers (depending on the degree of destruction of the wall). This is followed by an approx. 14-day drying phase, in which the active substances reach the wall via a concentration gradient and recrystallize there, condensing and strengthening. The wall stabilizes and dries completely. Finally, a primer and a protective coating are applied in two steps. From now on, the typical cellar smell is no longer perceptible and the drained room can be used immediately and as you wish.
