It can be just a white powder on your concrete salt like crystals white fuzzy stuff or what looks like white stalactites growing on your concrete wall.
White stuff on concrete wall.
While the white powder often found on basement walls and mold are caused by similar conditions they are actually different materials.
Instead this powder is a mineral salt that s usually recognized as efflorescence.
It is called efflorescence.
Efflorescence on cement wall.
The white powder is efflorescence or minerals left behind as water that has flowed through the concrete walls evaporates.
When water seeps through concrete brick or stone it can leave behind salt deposits.
These white deposits happen when water is drawn out of a cementious material.
Mold is a living organism that occurs in wet environments.
It s not a fungus though won t grow or spread and doesn t cause any of the health problems that mold sometimes causes.
Efflorescence can be found anywhere there is concrete or brick but the most common places to find this white substance is in basements hence the title of the page basement wall efflorescence it usually appears on the block walls but can also enter through mortar joints flashing cracks or absorption through porous areas in the masonry.
Efflorescence is a crystalline deposit of salts that can form when water is present in or on brick concrete stone stucco or other building surfaces.
Efflorescence occurs when water moves through a masonry structure bringing unbounded salts to the surface.
Efflorescence is the white powdery substance on the surfaces of unsealed concrete and the white blush seen with sealed floors.
When the water evaporates what remains is a white crystalline substance that resembles mold.
Efflorescence is caused by vapor migrating through the slab bringing soluble salts to the surface of the concrete.
This builds up on concrete surfaces in basements and in crawl spaces regularly occurring as part of the process of moisture coming from the earth passing via the concrete and evaporating into your basement.
It has a white or greyish tint and consists of salt deposits left behind when water evaporates.
The chalky white substance so often found on old brick cement or cinder block walls is efflorescence.
When the calcium hydroxide reaches the surface of the concrete it combines with carbon dioxide in the air to produce calcium carbonate or efflorescence.
Water is the key to triggering the reaction.
This dusty white salt like substance can show up immediately after the concrete has hardened or sometimes take days or weeks to present itself.
White mold growth provides an additional challenge because it is often confused with efflorescence a crystalline growth structure found on concrete and masonry surfaces.
What is that white stuff on your concrete or masonry block wall.
