Whitish mineral deposits that can appear on the surface of concrete pavers; appearance alone does not identify every white stain.
Definition and homeowner use
Whitish mineral deposits that can appear on the surface of concrete pavers; appearance alone does not identify every white stain. This definition helps separate a material or surface condition from the broader installation, repair or maintenance service that may be needed.
White deposit versus other staining
Efflorescence is a mineral-deposit term, not a name for all white discoloration. Residue from cleaners, coatings or other materials can look similar. Identify the surface condition before choosing a treatment.
Evaluate before cleaning
CMHA discusses efflorescence removal within concrete-paver cleaning guidance. Check the paver and cleaner manufacturer’s instructions, surrounding finishes and runoff precautions before applying any treatment.
Use compatible products
Select cleaners intended for the actual paver material and condition. CMHA recommends testing an inconspicuous area when evaluating cleaning products. Do not assume a strong acid or aggressive pressure washing is safe for every paver.
Sealing is a separate decision
Cleaning and sealing are separate operations. A coating is not a diagnosis of a white deposit or a repair for moisture-related conditions. Ask whether the surface is appropriately prepared and whether the selected sealer suits the pavement.
Requesting an assessment
Provide photos of the full area and close views of the observed condition. Mention drainage patterns, previous repairs and known cleaning or sealing products. Ask for the proposed treatment and its limits in writing; a photograph alone does not establish the underlying cause.
