When moisture and water vapor migrate to the surface of hardened concrete floors walls and colored concrete it carries with it calcium hydroxide.
Efflorescence on stained concrete floors.
But really the best approach to dealing with efflorescence is to keep it from forming in the first place.
In cases where moisture bubbles up from your basement floor it may even resemble a white foam on your floors.
Efflorescence is white powdery material formed on concrete floor surface when soluble salts migrate to the surface of concrete.
With any luck the efflorescence will stay away long term after enough cleanings have been performed.
Acid cleaning may discolor stained concrete so test it on a small section first.
Efflorescence is actually a harmless crystallized mineral salt that has formed on your basement walls over time.
It will generally look like a white powdery substance.
These surfaces allow water to travel within the surface.
A general rule for cleaning efflorescence is to try gentle methods first before moving on to harsher techniques source.
It is produced due to low temperatures moist conditions condensation rain dew and water added to the surface of fresh concrete to assist troweling.
Efflorescence is normally worn off or washed away on unsealed concrete surfaces.
The efflorescence can be happening when moisture starts to react with concrete causing some white stains in the concrete.
Efflorescence is caused by vapor migrating through the slab bringing soluble salts to the surface of the concrete.
It s induced by low temperatures moist conditions condensation rain dew and water added to the surface of fresh concrete to assist troweling.
Efflorescence will not only cause problems with a stained and sealed concrete floor it can also delaminate tile and warp wood floors.
It has a white or greyish tint and consists of salt deposits left behind when water evaporates.
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.
Concrete efflorescence is a very common problem on concrete especially decorative concrete.
It s also commonly found on floors.
The best approach would be to strip the sealer from a small area and perform a moisture test either a calcium chloride moisture test or an electronic surface moisture test so you can get an idea of how much moisture is in the slab.
Efflorescence is caused when soluble salts and other water dispersible materials come to the surface of concrete and mortars.
Some surfaces and mostly stained concrete will be more susceptible to the reaction than others.
