How to remove efflorescence from masonry?
In general, most efflorescence can be removed by dry-brushing followed by flushing with clean water . If brushing is not satisfactory, it may be necessary to use a very light (brush) sandblasting to remove the deposits. Brush sandblasting is sandblasting which is light enough that coarse aggregate is not exposed by the sand blasting (ref. 8). Sand blasting needs to be done with care, as it can alter the appearance of masonry by roughening the surface or exposing aggregate. There also are a variety of commercial cleaners available which may be effective for efflorescence removal. Consult manufacturer’s information for applicability.

Why is efflorescence difficult to predict?
Since many factors influence the formation of efflorescence, it is difficult to predict if and when it will appear. However, to reduce the probability of efflorescence occurring in masonry construction, it is necessary to minimize the amount of soluble salts and moisture present in the masonry. Of the two, moisture is the more easily avoided.
What is efflorescence in concrete?
Efflorescence is a deposit of soluble salts and bases, usually white in color , that sometimes appear on the surfaces of masonry or concrete construction. Although it may be an aesthetic concern, efflorescence will not affect structural performance.
Why is efflorescence more common in the winter?
Thus, efflorescence is more common in the winter when a slower rate of evaporation allows migration of salts to the surface.
Why does masonry have efflorescence?
Improper protection of masonry during and after construction can allow considerable moisture to enter, which can cause efflorescence. Masonry in contact with soil, such as in basement and retaining walls, may absorb ground water containing soluble salts.
What does it mean when a building has efflorescence?
If the efflorescence is essentially uniform throughout the exterior facade, it indicates normal water loss from the materials and the building. Some identify this occurrence as “early age” efflorescence or “new building bloom”.

Preventing Efflorescence
Taking care of building materials before, during and after the construction process can help prevent efflorescence. To keep a building in it’s best condition, consider taking some precautions. There are many solutions to prevent efflorescence, including:
Ways to Troubleshoot Efflorescence
When efflorescence does occur, it’s important that you’re able to troubleshoot and know what to assess to help determine the possible reason behind it. Determining this will help you decide how to remedy the situation. Consider the following when efflorescence is detected on a building:

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 process of water moving through concrete?
These salts and minerals are generally carried by water as it travels through concrete substrates. This process is called capillarity . Capillarity is best explained as the movement or transmission of water or moisture in masonry and natural stone.
What is efflorescence made of?
