Charlotte Home Inspector Explains Efflorescence

January 1st, 2012 · No Comments


Primary efflorescence is named such, as it

typically occurs during the initial cure of a

cementations product. It routinely occurs in

masonry construction, particularly brick, as well as

some fire stop mortars, when water moving through

a wall or other structure, or water being driven out

as a result of the heat of hydration as cement stone

is being formed, brings salts to the surface that are

not commonly bound as part of the cement stone.

As the water evaporates, it leaves the salt behind,

which forms a white, fluffy deposit, that can normally

be brushed off. The resulting white deposits are

referred to as “efflorescence” in this instance. In this

context efflorescence is sometimes referred to as

“salt petering.” Since primary efflorescence brings

out salts that are not ordinarily part of the cement

stone, it is not a structural, but, rather, an aesthetic


Sealant is needed to prevent water penetration

where the wood trim meets with the brick on the

front left corner of the house.
