Efflorescence: Causes, Repair, Prevention

Efflorescence

Since grout is a cement based product, it can be effected by efflorescence.

Efflorescence is a whitish film that forms when the salts and minerals from water rise to the surface and dry on top creating an ugly looking appearance on your grout and tile. For the most part, it looks way worse than it actually is.

What causes efflorescence?

While there are many causes of efflorescence in a shower pan, here are the most common:. Shower drain was not installed properly and/or weep holes are covered not allowing water under mud base to drain properly.. Too much water was used when grout was mixed.. Grouting was performed too soon after tile was installed. Water used in mixing or cleaning the grout was high in chlorine or had a high mineral content. Temperatures were too cold while grout was curing. Sponge was too wet when used to clean the grout from the surface of the tile. Grout joints were wiped excessively during initial cleanup. Standing water was left in empty grout joints prior to grouting. Grout was prematurely exposed to heavy amounts of water.
