    Ordinary portland cement versus white portland cement

    Hello,

    I have just finished building a concrete structure for a small swimming pool. I would like to go for a plaster finish, preferably grey. Therefore, could I use ordinary portland cement (which comes as grey) instead of white portland cement with a grey pigment? Many thanks for any advice.

    You are in Italy, I am in California. We are primarily a US based forum and most of the construction materials we use are based on US construction methods. Therefore I am very reluctant to give you advice on materials because I not only don't know what is available over there. That said here it is.

    Pool plaster is generally white Portland Cement mixed with fine sand and usually an acrylic fortifier. It can be purchased pre mixed or you can mix it yourself. If you were to buy Portland Cement and mix in the sand and fortifier then you would get a light grey color. But exactly what that color would be would not be predictable. That is why most start with white Portland Cement, follow a formula and add color because they want a predictable color.
