Best Answer

The atmospheric moisture is absorbed by the surface of masonry, flooring, or concrete through the joints, voids, or cracks. When the same water is evaporated from the surface, it leaches the lime compounds and forms the formation of salt deposits on the surface of masonry, flooring, or concrete. It is known as efflorescence or saltpetering.

What works best to get rid of Efflorescence muriatic acid or a different type of cleaner?

Bob is awesome A Real Answer::: Muriatic acid is around 30% + Hydrochloric Acid and is very harmful to any Portland Cement based material, be it concrete [poured, pumped or pneumatically applied], as well as grout mixes! This type acid attacks the lime in the mix which is the binder that holds a concrete together. Besides disintegrating a concrete it reduces the pH and sets you up for more problems in the long term. We do not recommend Muriatic At All! Several cleaners on the market profess to be a cleaner or remover. I use a buffered phosphoric product! First, we mechanically abrade the surface, removing as much of the salts as possible. Then we apply our remover and observe an aggressive bubble condition for 10 or so minutes. Rinse and reapply until no more bubbling is seen. This may require several applications to insure complete removal, however we have not compromised the concrete and created any conditions that will exacerbate a future problem. Rinse again and test for surface pH and provide a bath if necessary to bring the surface back to a 6-7 pH range. Once the efflorescence has been removed, apply a penetrating sealer, such as StableCrete to the surfaces to waterproof the concrete. A penetrating sealer migrates into the Gel-Pore/Capillary of a concrete and forms a solid inside the matrix. This stops contaminates and moisture from entering and also does not allow internal chemistry to migrate out of a concrete to react with an atmosphere! Efflorescence does not reappear and by having a reduced moisture content interior, freeze thaw damages are no longer a concern!

What does efflorescence and deposition of salts have in common?

Efflorescence is a phenomenon of dehydration of some hydrated compounds. Deposition is a change of phase, from gas to solid. I think that these processes have nothing in common.

Why is our limestone coping on our saltwater pool turning white?

It sounds like you are describing efflorescence or a mineral deposit. It would be easier if you send a photo. If it is at the water line it's most likely calcium deposits. If it's at the edge of the pool it's most likely due to water seeping out. (efflorescence)


How do you prevent efflorescence?

Brick Efflorescence Analysis• Firstly: There must be water-soluble salts present somewhere in the wall.• Secondly: There must be sufficient moisture in the wall to render the salts into a soluble solution.• Thirdly: There must be a path for the soluble salts to migrate through to the surface where the moisture can evaporate, thus depositing the salts which then crystallize and cause efflorescence.All three conditions must exist.If any one of these conditions is not present, then efflorescence cannot occur. Even though the efflorescence problem is complex, it is not difficult to prevent. Although no economically feasible way exists to totally eliminate any one of these three conditions, it is quite simple to reduce all three and make it nearly impossible for efflorescence to occur.Brick Efflorescence is the stubborn problem that has caused confusion and trouble for masonry since the first time it appeared thousands of years ago on ancient masonry walls. Efflorescence is normally the white, powdery scum that can appear on masonry walls after construction but can also be brown green or yellow, depending on the type of salts. Nobody likes it, nobody wants it on their walls, but occasionally this persistent problem appears.Great deals of time, money and effort have been spent trying to solve the difficulties efflorescence generates. Many test programs have been developed and numerous attempts have been made to eliminate this problem. Unfortunately, nothing has proven 100% effective against this very stubborn problem. However, even though no surefire cure has been discovered, a great deal has been learned about how efflorescence works and how to prevent it, and if preventive measures are inadequate.Consider taking the proactive approach of stabilizing a concrete to prevent moisture from traveling in or out of the matrix. A stabilizing product penetrates into the gel-pore capillary system to form a solid inside. This stops moisture from migrating out to the surface carrying chemicals with it, that then react with the atmosphere.This migration out to a surface, not only causes efflorescence, it also carries alkali's in the concrete to cause burning or peeling of coatings that have been applied.
