What is Efflouresence?

Efflorescence is a common problem that many people have to deal with around concrete and other masonry products. As part of being a homeowner, you need to understand what efflorescence is so that you can combat it as it happens. Here are the basics of efflorescence and what it means to you.

Primary Efflorescence

The first type of efflorescence is called primary efflorescence. This type of efflorescence occurs when concrete or masonry work is in the process of curing. The idea behind this type of efflorescence is that the water within the concrete comes to the surface. When it does this, the water could have minerals within it. As the water comes to the surface and evaporates, it leaves behind traces of minerals. You will notice a small, white, flaky substance on the concrete or masonry work.

Secondary Efflorescence

Secondary efflorescence is a phenomenon that does not happen when the concrete is drying. However, on the other hand, it takes place because of some outside influence that does not mix well with the concrete. For example, where concrete meets steel on a bridge, secondary efflorescence can occur.
