- What is Efflorescence?
A white haze that may appear on the surface of the pavers.
It may appear randomly or in certain areas, and will be more pronounced on dark
colored pavers.
- When will Efflorescence Stop?
When the supply of calcium hydroxide is exhausted. If
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 approximately 18 to 24 months.
- Will it go away Naturally?
Since many factors are involved in its formation, it is
difficult to determine when efflorescence will eventually disappear. Over time,
rainwater can wash and wear it away. In urban areas with acidic rainfall,
efflorescence may to away faster than in rural areas.
- Can it be removed without the wait?
Yes, efflorescence may be cleaned with commercially available
cleaners formulated specifically for concrete pavers. Cleaning should be performed
immediately after efflorescence has appeared. It may reappear as long as the
chemical reaction continues and cleaning may need to be done until efflorescence has
stopped.
