Can Alginate be Used in Place of the Silicone Smooth-On Product? Answered

I realize you mentioned in the introduction that Alginate can be used for plaster molds. I am attempting to make a mold of a 3D print and then cast in it plaster. The "plaster" I have though is Durnham's water putty (https://low.es/2KjMzKX). As Alginate is a water based mold as is the putty, will this cause any issue when pouring or setting up? Thanks in advance, you've done a great job with the class!
