Whether it’s for aesthetic purposes or to save the integrity of your walls, preventing efflorescence is a good idea. This can lead to the masonry breaking apart, or “spalling.” This can create hydrostatic pressure that could be greater than the strength of the masonry. Then, if the salt concentration on the surface increases too much, more water will rush towards it to dilute it. If your brick walls come into contact with water too often, efflorescence will increase. Most manufacturers are careful to wash their aggregate before it goes to the customers.Įxcessive efflorescence can also be a sign of moisture issues, however. The salt can be a natural consequence of the manufacturing process. It then evaporates, leaving the salt behind.Įven with masonry paint, most masonry material is breathable enough to allow the salt to come through. If it’s present, the water carries it to the masonry’s surface through capillary action. The water and the masonry itself can contain salt. The water comes from a secondary source, such as rain or groundwater.
