The paste has clumped me in touch. I do not know why, because I have stirred neat and me thus could not quite explain. At first I was shocked, because I could get on the fast no new paste (Sunday -.-). I've tried it anyway and was surprised that the paste gave a thick and thin fleece fabric neatly on the wall. There was no point at which times broke a piece of wallpaper. Therefore, I would order this again paste. The hardware store because you have to pay for normal brand paste 7 or more.
