Efflorescence (White Powder) Is Present On Masonry Or Stucco Surface

Acceptable Performance/Condition
Efflorescence commonly occurs on masonry and stucco surfaces and is normal. No warranty.

Warranty
None.

Action
The builder is not required to take any action.

Remarks
Efflorescence is the harmless deposit of mineral salts on the surface of masonry and occurs naturally due to the movement of moisture; it may diminish over time. Visibility varies with seasonal conditions. Dark-coloured bricks tend to exaggerate the appearance of efflorescence. Localized areas of efflorescence may be linked to abnormal sources of moisture. Salt and de-icers may also contribute to efflorescence.
