Efflorescence...


What is Efflorescence & How do I Fix It?

Efflorescence is a whitish powder or crusty deposit which appears on the surface of the grout joint or along the edge of the tile. In porous tiles, efflorescence may appear on the surface of the tile. See below for an example.





The appearance of this on colored grouts is either in patches or as an overall lightening of color.

Salt deposits are white, thus efflorescence is more noticeable in darker colored grouts.

To fix this problem first try a stiff bristled brush on the problem areas.

If this doesn't solve the problem there are products available that you can use to remedy this issue. These products are available to special order in store.
