You Keep Using That Word

Mom left a note four Johnny too go two the store for to candy bars. But, when he got their,
they stated that there selling all the candy bars to that man over they’re.

Words are important, because they convey a thought or a meaning.  Words are used for communicating and communicating is the act of conveying an idea from one person to another.  When we have many words for the same thing, it can cause a great deal of confusion.

you keep using that word, I do not think it means what you think it means

For example, I lived in Atlanta for a while and one thing that caught me off guard was the reply to a very simple request?  I simply asked for a coke at Varsity’s.  A Coke!  What do you think of when I say Coke?   I was stunned by the question that followed my request.  What flavor?  Do you want Cherry, Orange, Grape, Diet, or regular.  What?, Really?  I just want a Coke.  I came to find that “Coke” is a generic term in the south meaning a carbonated beverage.  I had heard it called Soda, Pop, even Soda-Pop but to call it by a brand name was something new to me.  Now Atlanta is home to Coca-Cola and they must have a great marketing department to have the whole south calling all soda/pop “coke”. 

I have found in this industry, a similar thing is happening with the word EFFLORESCENCE.  EFFLORESCENCE means to flower out or to bloom.  That is what happens as water migrates through a wall, it collects loose salt and lime and brings them to the surface. As the water evaporates, the salt or lime particles bond to the wall causing white stains. It “blooms” on the wall. A process Jose’ Cuervo loves, I am sure.

White stains are where we get confused as not all white stains are EFFLORESCENCE. 

Calcite or calcium carbonate appears as a thick whitish deposit that usually forms over time. Calcite will most commonly form on brick and block, when excess moisture evaporates and leaves behind a heavy calcium residue. This is similar but not the same as Efflorescence.  This can be corrected by using Calcite Presoak (undiluted) followed up by NMD80 at 4:1 dilution. You may need more than one application of Calcite Presoak.  Do NOT rinse between applications.

Lime Run occurs as a steady release of calcium soaked water that creates a streak. Generally, lime run is treated just like calcite. Though caught early enough, the normal wash process of NMD 80 (4:1) will be effective enough to remove it.

White scum, or calcium silicate, has traditionally come as a result from improper use of a new masonry cleaner, reacting with brick and forming insoluble salts. This is created by un-buffered acid combining with silicates and clay.  To fix this just use White Scum Presoak (undiluted) followed by NMD80 at 4:1 dilution.  You may need to apply White Scum Presoak multiple times.  Do NOT rinse between applications.

Integral water repellents or admixtures can sometimes bleed out of the brick or block, leaving behind a "white stain" that has very similar characteristics to efflorescence or white scum; however the removal process is completely different.  OneRestore is used to remove the hazing.
