Question: What is the white powder that is appearing on some areas of the concrete floor and walls?
Answer: The white powder, known as efflorescence, is caused by salts in the concrete mix that are brought to the surface as moisture evaporates during the curing process. This is a normal occurrence and leaves a harmless salt deposit that can easily be brushed off. Efflorescence does not impact the strength or performance of the concrete and typically stops forming once the curing process is complete. Regular sweeping or light cleaning can help remove the deposits as they appear.
