What do you mean by sodium silicate? If we take this literally with the
formula Na0(n)SiO2, where n is usually between 3 and 6, you are in deep
trouble. This is a deliquescent, amorphous substance which will turn
into waterglass by absorption of atmospheric humidity. Apart from this,
it becomes a viscous liquid to which anything will stick.

Sodium disilicate, metasilicate and orthosilicate aren't quite as bad,
but are nearly so. They are all highly water-soluble and may be
hygroscopic, to some extent.
