There are a number of people who confuse stucco and plaster in a lot of ways. Whereas they are similar in many ways, the difference comes into understanding where and how to use them. The difference is not quite apparent to the naked eye; both the plaster and stucco are applied in the almost same way, maintaining the same thickness and texture. However, different set o ingredients are used to make them different from each other. Get into the insight with this content-
Where does the difference lie:
Whereas, it is already mentioned that both of the mixtures contain different ingredients- sand for various textures and sizes, different kinds of aggregates are mixed together to activate the curing process.
However, the big difference lies in the blinder that holds everything together and cures into the rock hard consistency.
How does the stucco work?
In recent stucco mixture, the Portland cement, lime with synthetic fibres and acrylics are added in. Stucco is sometimes called render and applied with a number of additives like plasters to withstand the weather elements. The additives like Portland cement, lime, brick dust, fibreglass, sand, mud, etc. are used for exterior rendering services. Plaster is used for interior walls, stucco becomes as hard as stone to withstand the harsh storm.
Despite the difference between stucco and plaster, both the plaster and stucco create a tight seal to act as a sound barrier, which is great for the noisy areas. You can also give your home a personal touch with stucco and plaster. While creating super smooth walls with unique textured patterns, painting can be applied in both of the cases in a variety of colours.
How does the plaster work?
Depending on the type of plaster you have, you will get two types of blinder-
Lime: It is a primary binder in plaster and in the early 1900’s it was a cheaper option to acquire than the expensive gypsum plasters. The lime plaster takes labour for mixing water and lime and you have to keep it until it slakes. Moreover, lime plaster takes an extremely long time to cure and takes as long as a year before panting or applying wallpaper on it.
Gypsum: Have you ever heard of plaster of Paris? It is another name of gypsum plaster. The nickname is given due to how Paris was built on the top of the gypsum deposits. Did you know the gypsum cures and sets fast than the plaster?
Gypsum plaster is the interior plaster and not ideal for exterior use, as they are better for repeated exposure to water. On the other hand, with certain additives, lime plasters can face most weather condition with a long useful life.
When installation matters, it requires trained experts to for both the stucco rendering and plastering services. Whereas stucco is applied in three layers over a wire lath (similar to wire mesh), gives stucco a surface to adhere to it. With a consecutive scratch coat, brown coat and thick smooth layer, the stucco can give a distinctive textured appearance.
