How to prevent efflorescence of tile?

Some solutions that you can consider for a new tile installation would be to use a waterproof membrane beneath the installed surface. This helps minimize or eliminate efflorescence-causing salts and minerals from migrating from below. This is especially important in wet areas such as fountains, spas, steam showers, etc. This is not a foolproof solution as you are still vulnerable to exterior elements such as rainwater, sprinklers and moisture from the air penetrating your surface moving down to the cementitious adhesives subsurface. In this last scenario, the moisture transmission begins again which may lead to efflorescence occurring on your surface. This can be minimized or eliminated by applying a good, breathable penetrating water repellent to your surface. Actually many good water repellents can help efflorescence from occurring when the original source of moisture is coming from the exterior elements or from below.

Why does tile have efflorescence?

This is likely due to capillarity. If the stone or tile is installed on a concrete substrate, or if there is moisture originating from the setting material (e.g., thin set, mortar), or if any component is mixed with water, then moisture will travel through the stone and/or grout to the surface. Sometimes alkali surfaces, like limestone, marble, concrete or grout, may be the source of salts and minerals. Just the water used in installation can be enough to trigger migration of these salts and alkalis to the surface resulting in efflorescence without the usual migration from the setting materials below. In all cases, the salts and minerals need water or moisture as the carrier to bring them to the exposed surface level. In situations where a fat mud setting mixture is used (when additional lime is added to the mortar) there may be a heightened probability of efflorescence occurring.

What is the role of latex in cleaning?

What is Efflorescence?

Efflorescence is a residue of mineral and calcium deposits that settle on the surface once the water evaporates. This water originates from leftover moisture or water underneath the tile at the time of installation. The water mixes with the minerals in the concrete mud bed, grows in volume and travels to the outside through a drain or any other seepage. If not removed at the right time, it can crack your tile and grout and also clog your shower drains.
