Efflorescence can appear in or on hardscape such as brick, concrete, stone, pavers, stucco and other building materials. Efflorescence meaning, “to flower out” in French. Is the sparkly, powdery white/grayish tinted substance that forms upon exposure to air, as crystalline deposit emerges from pores within hardscape through loss of water. Meaning the calcium deposits are carried to the surface by water when the supply of calcium hydroxide is exhausted (diagram above). This crystalline deposit of salts forms when hardscape is exposed to water, rain, and snow. Just as it appears naturally, efflorescence can also disappear naturally. Although, it can also be removed manually as well. We hope this quick discretion answered your questions.
