FH 4.17: Efforescence (Typically a while powder film) is present on masonry exterior finishes

Efflorescence commonly occurs on masonry surfaces and is normal. Localized concentrations of efflorescence on above grade masonry veneer walls visible from no less than 6 m may not be acceptable and may require further investigation.

One-Year - Work and Materials. · Efflorescence resulting from additions, deletions or alterations made by the homeowner or improper maintenance is not covered by the statutory warranty.

If it is determined that a defect in work or material is the cause of the efflorescence, repairs shall be made.

Efflorescence is the formation of a typically white crystalline deposit on the surface of masonry when moisture evaporates from the surface. Efflorescence can be removed using a stiff bristle brush and water. 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 and in that case the item is not warrantable.
