Efflorescence Treatment

Efflorescence is the crystalline deposit of salts often seen on the surface of concrete, brick, stucco or natural stone surfaces. It usually looks like a white powder on the edge of the surface.  However, if the surface is particularly porous, eg sandstone, the tiles itself will have the efflorescence.

Efflorescence usually occurs when the tiles have been installed over concrete that has not completely dried. Basically, as water evaporates, the minerals and salt deposits are too heavy to evaporate.

Although most Melbourne home owners consider it to be very unsightly it won’t make you sick like mould can. However, while people think that it’s mainly a cosmetic issue, it can also indicate excessive moisture or leaking underneath the tiles or floors of your Melbourne home. In addition, water leaks can lead to weakening tile glue. This can cause your tiles to fall off or become loose. In addition, it may also cause structural damage. This type of damage can occur in both Melbourne free-standing homes as well as high-rise apartments.

Melbourne is more prone to efflorescence. This is because in cooler climates, concrete that is laid in winter is more likely to produce efflorescence. This is due to bricklayers and tilers often using calcium chloride to accelerate the set time of the concrete.

Efflorescence is commonly found on garage floors, house slabs, foundations, concrete, patios, driveways, courtyards, pathways, retaining walls and chimneys.
