If you're new to home improvement and taking active participation in building and/or remodeling your home, chances are you're suddenly overwhelmed with a completely new sea of terms that you've never heard before. Not only that, the amount of available options and products on the market that you can choose from is oftentimes baffling, leaving you wondering - what happened to the good old times, when there were five of everything and making a decision was the easiest part of the project.
In this article we'll give you more insights into stucco and plaster, answering questions like if and what is the difference between the two, how they are used, why people choose plaster and more.
Is there a difference?
Most sources will tell you that in essence there's not much of a difference between the two. They're both used as finishing materials for walls and ceilings. What you can see is that people often use the opposing terms to differentiate between indoor and outdoor surfaces. In short, one would use stucco when referring to the finishing material of exterior surfaces of the buildings, while using plaster to indicate a wall finishing material necessary for indoor use.
Stucco usually consists of a mix of sand, Portland cement, lime and water, but may also consist of a proprietary mix of additives containing fibers and synthetic acrylics that add strength and flexibility. It can be applied as one base layer and a finish layer, which is thinner and faster to apply, compared to the traditional application of three-coat stucco.
Plaster, on the other hand, usually consists of cement, sand, and gypsum. It also has many different variations with different application methods.
The two construction materials are dry powders mixed who need to be mixed with water to form a paste necessary for application. Both include an aggregate such as sand, and both need water to activate the materials allowing it to cure. The important difference between stucco and plaster is the binder that holds both materials together, i.e. lime and gypsum.
Because of its ingredients, stucco can be considered a more durable finish than plaster. Stucco is also less likely to require any sealants or painting after it has been applied, which makes it perfect for exterior applications. Additionally, because of its finer texture, stucco can potentially be used on a wider range of surfaces than plaster.

The good news, however, is that a lot of these products have the same idea and purpose behind them and the most notable difference is the decorative element within it. So you may find your answer, based on the final image you want to see.
