More than a decade of masonry works unselfishly provided our company time to research through first-hand experience about efflorescent culprit.
Few times, in the younger years of our company works, some client reached out to us after a month or so pointing their fingers on us because a fine, white, powdery deposit appeared in their walls (stones or bricks). That salt like deposit is efflorescence.
According to the Masonry Institute of America (nd), Efflorescence is the stubborn problem that has caused confusion and trouble for masonry since the first time it appeared thousands of years ago on ancient masonry walls. Efflorescence is normally the white, powdery scum that can appear on masonry walls after construction but can also be brown, green or yellow, depending on the type of salts. Nobody likes it, nobody wants it on their walls, but occasionally this persistent problem appears.
