Salts which leach out of 'tufa during the curing process.
A powder or stain sometimes found on the surface of masonry, resulting from deposition of water-soluble salts.
(paint) is a white fluffy surface deposit that is caused by salts in the plaster being drawn to the surface. The moisture evaporates and the efflorescence appears. Dry brushing will remove it. (Do not wash with water, as this will aggravate the problem). For the first coat, if it is a new surface use latex, if an old surface use latex or alkali-resiting paint.
Efflorescence refers to fluffy, white salt deposits that are leached out through plaster as water passes through it.
Migration of water-soluble compounds to the surface of a pot as it dries (see boxes, p.106, 136)
a powdery deposit on a surface
A white powdery substance that can form on new block, brick, or stucco finishes. It is composed of water-soluble salts that are present in masonry materials and that rise to the surface via water evaporation.
crusty, white salt deposits leached from masonry or mortar as moisture passes through. Usually caused by: excessive moisture; inadequant venting of interior moisture laden areas; pH level too high; or excessive lime in concrete mix.
An unsightly white or light-coloured crystalline salt bloom or ‘scum’ that builds up to disfigure new concrete surfaces, either those coloured with recommended pigments or non-pigmented. Efflorescence is caused by the evaporation of the mixing water when the new concrete is not cured properly (see ‘ curing’). It is different to laitance and is caused by the migration of soluble salts to the surface of hardened concrete.
The forming of a white powdery substance on the surface of concrete or brick.
This occurrence refers to a whitish coating of calcium-carbonate mineral salts that can form on the surface of a concrete countertop piece. If moisture seeps through the concrete, it can bring with it free calcium salts in the concrete, which it deposits on the surface as it evaporates. Efflorescence can occur due to the unpredictable and uncontrollable composition of sand and aggregates in bagged concrete. See "Efflorescence," page 149, in Concrete Countertops.
A white powdery deposit of soluble salts of calcium, potassium, and sodium which forms on the surfaces of masonry. Efflorescence is caused by the release of excess “water of crystallization†and/or moisture penetration, thereby, causing the leaching of these salts to the surface when the water evaporates. See article "Efflorescence, Causes, Removal and Prevention"

Water stains formed on the surface of brick or concrete caused by moisture penetration.
Deposits on a concrete surface formed when calcium hydroxide and other water soluble salts leach out of concrete. MetaMax® reduces efflorescence by converting calcium hydroxide into a non-water soluble compound.
A deposit or encrustation of soluble salts, generally white and most commonly consisting of calcium sulfate, that may form on the surface of stone, brick, concrete or mortar when moisture moves through and evaporates on the masonry.

Formation of white crystalline deposit on the face of concrete surfaces.
A white deposit of calcium carbonate on concrete surfaces. It results from the reaction of calcium hydroxide with carbon dioxide from the air. The calcium hydroxide is a byproduct when cement hydrates. It is slightly soluble in water and migrates to the surface through capillary action. The calcium hydroxide remains on the surface, reacts with carbon dioxide, which forms calcium carbonate and water. This conversion, depending on weather conditions, will dissipate over time. Calcium carbonate is the most common type of efflorescence. The presence of efflorescence does not compromise the structural integrity and is not indicative of a flawed product.
The process by which water leeches soluble salts out of concrete or mortar and deposits them on the surface. Also used as the name for these deposits.

White powdery substance on the surface which is the result of soluble salts within the substrate migrating to the surface.
The process of dissolved minerals and salt in water being deposited on the surface of masonry. This is due to either water used in the mortar having a large amount of dissolve minerals, or the absorption of water from the ground. This is in the vast majority of cases this is purely cosmetic, and may be removed by scrubbing the surface and washing with clean water.
A white crystalline deposit of salts on the concrete surface.
