What is EFFLORESCENCE?
Efflorescence is the term most commonly used to describe the deposit of crusty white mineral salts that appear on a masonry surface (concrete, render, brick or mortar) that has leached out from within the substrate when moisture migrates through it.
Efflorescence can happen at different times. Essentially, it can either be a problem from the beginning of a building’s construction, or the process can occur over time. Primary efflorescence usually occurs within the first 72 hours of the building material being used, appearing due to excess water being present when the material is manufactured. Secondary efflorescence is a result of outside moisture pulling the salt out of the building material at PH Exterior Cleaning Services we use the appropriate mix of strong industrial chemicals to remove stubborn efflorescence. The exact approach will be discussed and agreed at the time of site survey
