Efflorescence is the build-up of salt to the surface of a porous material, where it forms a thickened white powder like layer. Commonly effected areas include masonry surfaces such as bricks, sand stone, concrete and cement render to name a few. You may have noticed it on the façade of a building, or even on the surface of tiles and grout. Not only is it unattractive to look at, it could even cause damage to a building. The build-up of salt causes corrosion to masonry substrates such as is found within buildings made from bricks or sandstone. Over the course of time, corroded bricks could pose harm to the structural integrity of a building.
Where a build-up of crystallised salt appears on tiles for example, detecting the reason for the build-up could come down to various factors. Efflorescence on tiles could be the result of the concrete slab or cement screed, hence why a specialised 2-part membrane should be applied to the screed prior to tiling. This ensures that salts are not deposited to the porous surface of the tile and grout. However this is not always the case. In our experience of salt prevention and treatment, Efflorescence could also be the result of the adhesive or grout used as the minerals and chemicals used in the manufacturing process contain certain characteristics which lead to an occurrence of salt. Drip Drop Stop can assure you that the prevention and treatment of your surface can be repaired, using environmentally friendly solutions.
