Introduction to Efflorescence
Efflorescence – Introduction: Efflorescence is a white powdery substance that is often seen on the surface of masonry units, brick, and concrete. It is a result of water vapor passing through the material and depositing soluble salts on the surface.
Efflorescence Treatment: The most common method of treating efflorescence is to remove the source of the water vapor. This can done by repairing any leaks in the masonry, improving the drainage around the masonry, and reducing the amount of water vapor entering the material. Once the water vapor has eliminated, the efflorescence will usually disappear.
Masonry Efflorescence: Efflorescence that appears on the surface of masonry units, brick, and concrete often referred to as masonry efflorescence. This type of efflorescence caused by the passage of water vapor through the material and the deposition of soluble salts on the surface.
Chemical Efflorescence: Efflorescence that appears on the surface of masonry units, brick, and concrete often referred to as chemical efflorescence. This type of efflorescence caused by the migration of soluble salts to the surface of the material.
Brick Efflorescence
Brick efflorescence is a white powdery substance that appears on the surface of bricks. It caused by water that seeps through the bricks and dissolves the salts that are present in the brick. The water then evaporates, leaving the salts behind in the form of a powder.
Efflorescence in Cement
Efflorescence is a white powdery substance that is often found on the surface of concrete, mortar, and plaster. It made up of minerals that have leached from the concrete, mortar, or plaster, and it can often removed by scrubbing it with a brush.
Efflorescence on Walls
Efflorescence is a white, powdery deposit that can form on the surfaces of walls, masonry, and concrete. The deposit composed of minerals that have dissolved in water and then redeposited on the surface as the water evaporates.
Efflorescence Plaster
Efflorescence is a white powder that can form on the surface of plastered walls. It caused by soluble salts that come to the surface as the plaster dries.
There are a few ways to deal with efflorescence:
- If the efflorescence is only on the surface, you can brush it off.
- The efflorescence is more severe, you can use a wet vacuum to remove the powder.
- If the efflorescence is in between the cracks in the plaster, you can use a sealant to stop the salts from coming to the surface.
Efflorescence on Stone
Efflorescence is a white, powdery substance that can form on the surface of stone. Therefore it caused by the evaporation of water that has absorbed by the stone. The water carries minerals with it, and these minerals deposited on the surface of the stone. Efflorescence can removed with a stiff brush or a power washer.
Examples of Efflorescent Salt
Some common efflorescent salts are sodium chloride, potassium chloride, and also magnesium sulfate.
