Stucco in English refers to coating on outside and plaster refered to internal coating.

Stucco plaster are categorised into two types:

Traditional Stucco plaster:

It is a mixture of lime, sand, and water.

Modern stucco plaster:

It is a mixture of Portland cement, sand, and water.

In modern stucco plasters, lime is replaced by Portland cement for increasing durability. For many special purposes, Instead of lime plaster, gypsum player use.

To improve structural properties, acrylic and glass fibers are used in modern stucco.

Stucco is used like any other plaster to cover the bricks or concrete surfaces and give an appealing and finished look.

It is made up of OPC, fine aggregate and water. It is very common in India and goes by the name “Plaster“. The advantages of Stucco is that it is very durable and can be further strengthened by adding fibers into it.

However in other countries, “Plaster” is made up of Gypsum or Lime instead of OPC. When cement is used as a binder it is called as “Stucco”.

Stucco is a construction material made of aggregates, a binder and water. Stucco is applied wet and hardens to a very dense solid. It is also used as a decorative coating for walls and ceilings, external building siding, and as a sculptural and artistic material in architecture. Stucco may be used to cover less visually appealing construction materials, such as metal, concrete, cinder block or clay brick and adobe.

But stucco sometimes refers to a coating for outside of a building and plaster to a coating for interior; the material itself is little different.

Stucco is a portland and lime based product. For added strength and support we will sometimes mix bits of fiberglass strands in with the mud. The fiberglass acts as another structural support to make sure cracks stay away and no chunks will fall off. To add some fun texture, different types of sand are used in specific quantities to make sure you enjoy every inch of your home.

Stucco is applied by an industry specialist to the interior and exterior walls. An expert can apply the plaster manually or by using a machine. This portland cement plaster can be used on concrete wall systems, or on a frame structure. It is used for siding, or to cover concrete, cinder block, clay brick or adobe.
