First, for very mild cases of efflorescence, try a 50/50 mix of white vinegar and water. Using a scrub brush, spot treat and scrub affected areas with the vinegar mix. The acidity in the vinegar helps remove the efflorescence and calcium deposits by breaking down mineral crystals.
Is efflorescence bad for bricks?
Occasionally, a white crystalline deposit will appear on its surface. These deposits are likely water-soluble salts referred to as efflorescence. Although undesirable, efflorescence is usually not harmful to brick masonry.
How do you prevent efflorescence?
How to Prevent EfflorescenceUse high quality concrete that contains minimal water. … Make sure the sand and gravel used in concrete has been washed and that the water in the mix is pure and salt-free. … Use low-alkali mortar for stone or brick work so that alkali salts don’t leach into the masonry. … Cure concrete or stucco properly.More items…
Is efflorescence a problem?
Efflorescence alone does not pose a major problem, but it can be an indication of moisture intrusion, which may compromise the structural material. Building materials, such as concrete, wood, brick and stone, are porous materials. … The ground in which these materials can come into contact also contain salts.
How long does it take for efflorescence to disappear?
18 to 24 monthsIf you live in an area of frequent rain and sunny days, efflorescence and its passing may occur quickly. The process may take much longer in drier climates. Typically, efflorescence will stop developing in approx- imately 18 to 24 months.

Can you Drylok over efflorescence?
Since efflorescence is an alkali salt, remove it with liquid or powder DRYLOK® Etch or muriatic acid, paying close attention to usage and safety guidelines.
How do you fix concrete efflorescence?
To fix the problem at this point, clean the surface with a mild acid or efflorescence remover (some manufacturers make special efflorescence cleaners) followed by sealing. To avoid the problem altogether on future projects, consider using a colored curing compound or cure and seal to match the color of the concrete.
Does vinegar remove efflorescence?
Vinegar and water solution—Efflorescence can be removed by using a dilute solution of household white vinegar and water. A vinegar and water solution is relatively inexpensive, non-toxic, and easy to obtain, mix and apply.
Does sealing stop efflorescence?
Simply sealing concrete from water penetration (using a penetrating sealer) will help prevent efflorescence. V-SEAL creates an incredible water barrier for brick, mortar, and all forms of concrete. To help prevent efflorescence, V-SEAL should be sprayed anywhere brick, mortar or cement will be exposed to water.
Can I paint over efflorescence?
Some paint coating systems may have varying levels of resistance to efflorescence or alkalinity however there are no guarantees or warranty. … Painted surfaces already damaged by efflorescence must NOT be repainted until the source of the moisture is identified and eliminated or blocked (by waterproofing).
Will a dehumidifier help with efflorescence?
Dehumidification is not a permanent solution In fact, if a dehumidifier is used in a basement with moisture problems, it may cause greater damage. By drying out the basement air, moisture is drawn into the basement more rapidly causing efflorescence and spalling of concrete and further damage to interior finishes.
Does efflorescence go away?
Yes. Although efflorescence will eventually go away naturally, there are commercial cleaners available that are specifically formulated to remove efflorescence from the surface of the concrete pavers.
