Efflorescence is that white chalky stuff
That appears on a masonry wall
Only a surface problem, enough
To make one’s poor skin crawl.
It is caused by water evaporation
Leaving salts of sulfate
It happens all across the nation
And is just too common a fate.
To stop this from happening is not always easy
The culprit’s alkali sulfate
It makes masonry look kinda cheesy,
The water should not percolate:
Through a brick wall, or mortar or stone,
Because water leaves this white scum
And can leave a mark on your home
Aesthetically unbearable to some.
So how do I stop it and why?
What do I do and what is the essence?
Just keep your masonry dry-
And you'll have no efflorescence.
