I reached out to Bioshield directly with your questions. The part that gave us both pause was the idea of this going over "new, raw white plaster"If the plaster is NOT cured, that alkalinity will wreck havoc with any finishes that are not designed to work with uncured surfaces like lime plasters and concrete. The glaze is not something that can work on these conditions. If your plaster is sealed (most professional plasterers use something like Okon) then it would probably be okay.That said, this will dry clear if you use it on it's own. If you tint it with pigment or mica powder, obviously this will change how your walls look. Multiple coats will give the wall an eggshell like sheen. Bioshield recommends 2 coats minimum.If you want to paint over it someday, you would be fine going over it with a primer then wall paint, like painting over any previously painted wall.We offer sample sizes so you can test yourself and see if there is any odd reactions between this product and your raw plaster. You can also use this for testing pigments addition, and the aesthetics of painting clear layer first and tinted layer next and vice versa.
