Anyone who has read my review of WEPOS Schimmelentferners, is yes coarse know the way already.
I can recommend both products fully combined.
Although the whole place stinks of chlorine afterwards, but the mold is really effective way.
Have treated more than 2 months ago with the remover and the impregnator my bathroom ceiling and far to see still 00:00-nix moldy.
PS: Again, I recommend the use of gloves)
