Alumina cement vs. Portland cement
I was never good at chemistry and I would bet most tile setters aren’t that interested in the chemical difference between Alumina and Portland cements so I will try to break it down to layman’s (or journeyman’s) terms.
Portland is fine for most construction and building purposes and it is very inexpensive to purchase and to use. However, it’s final color can dramatically be affected by moisture content and relative conditions. In addition, Portland cement tends to contribute to efflorescence because of its high calcium content.
Aluminite cement is stronger, has less calcium, and has been kiln-tempered to achieve a purer content.
I like Kiesel products because they contain high quality aluminite cement. In fact, their aluminite cement is purified 3 or 4 times to reach the highest level so Kiesel cements are some of the strongest in the industry.
It’s That Simple!
