The difference between plaster and render

Plaster and render are two materials that are often used in construction and home renovations. While they may seem similar at first glance, there are several key differences between plaster and render that it is important to understand.

Plaster is a material that is made from a mixture of water, sand, and lime or gypsum. It is often used to create a smooth, even surface on walls and ceilings. Plaster is applied in a wet state and then allowed to dry, at which point it hardens and creates a solid surface. Plaster is often used in the construction of new buildings, as well as in the renovation of older ones.

Render, on the other hand, is a thin layer of material that is applied to the exterior of a building. It is usually made from a mixture of cement, sand, and water, and is applied to the outside of a building to create a protective layer. Render is often used to protect buildings from the elements, as well as to improve their appearance.

One of the main differences between plaster and render is the way they are applied. Plaster is typically applied to the inside of a building, while render is applied to the outside. Plaster is also applied in thicker layers than render, and is typically finished with a smooth, even surface. Render, on the other hand, is usually applied in thinner layers and may be textured to create a more decorative finish.

Another difference between plaster and render is the type of materials that are used to make them. Plaster is typically made from a mixture of water, sand, and lime or gypsum, while render is made from a mixture of cement, sand, and water. The specific mix of materials used to make plaster and render will depend on the specific application and the desired properties of the finished product.

In terms of durability, plaster is generally considered to be more durable than render. Plaster is resistant to water and is not prone to cracking or chipping, making it an ideal choice for areas that are prone to moisture. Render, on the other hand, is more prone to cracking and chipping, especially in areas with extreme weather conditions.

Overall, plaster and render are both important materials that are used in construction and home renovations. While they may seem similar at first glance, they have several key differences in terms of the materials they are made from, the way they are applied, and their durability. Understanding these differences is important when choosing which material to use in a specific application.
