Have you ever noticed some powdery, unsightly white stains on the concrete of your building, sidewalks, parking garages, or other exterior surfaces? When soluble salts and other water dispersible materials come to the surface of concrete, you will notice efflorescence. Unfortunately, this time of year with low temperatures and moist conditions, increases the efflorescence you see on your concrete. This efflorescence is actually lime deposits on your surface.
Efflorescence requires a couple conditions in order to occur. First, it can only occur on certain surfaces, usually ones that are porous and where water can reach or “leach” out of the surface. This means surfaces like clay, concrete, brick, stucco, or wood. Second, it only occurs on surfaces that the are located somewhere where a sufficient moisture accumulation is possible.
Typically, efflorescence is more noticeable on darker colored surfaces compared to white or light gray. The contrast of white and dark colors will enable you to see the efflorescence more than usual. Therefore, if you have a building with dark brick, the efflorescence will show dramatically more than a white concrete building.
Thankfully, efflorescence is not harmful to the integrity of your building. Despite what you may think, it is not a sign that your building surface is disintegrating or dissolving, and you don’t need to worry about replacing it. The white stain is simply a collection of minerals, that the surface of your building already contained in the first place.
