For the past few years here at Walls & Ceilings magazine, we’ve been considering the fundamentals of traditional plasters. We began with the basics, explaining what makes something a plaster, where you might expect to find different plasters utilized, as well as the practical functions they perform in architecture. Next, we gave an overview of the few simple components making up traditional plasters, paying especially close attention to the chemistry and physical properties of the binders, the “mineral glue” that most influences how a plaster will perform.
Here we take it one step further by mixing things up a little, seeing what happens when we blend certain plaster binders together and identifying which plaster binders play nice together and a couple that are best avoided.
