Advantages of gypsum plaster you should absolutely know

Plastering is one of the most ancient building handicrafts. Historical evidence shows primitive man plastered mud over a framework of sticks and reeds that served as protective structure against the elements.

It is known that plaster work, and the decoration upon it, was applied more than 4,000 years ago. The Pharaohs of Egypt used plaster surfaces in their palaces and pyramids, which still exists in a hard and durable state today. Research has also indicated that the principal tool used for plastering in ancient Egyptian were nearly identical to those used today.Plaster was recognised long ago as a protection against fire. Its value as fire retardant was demonstrated in the many fires that ravaged London during the 13th century. The king at the time ordered that all buildings were to have plastered walls.

Gypsum plastering is a modern day solution to time consuming and ecologically straining process of Sand Cement plaster. Gypsum plasters have been used for centuries in the construction space, owing to its excellent and unique properties. It provides excellent thermal and acoustic properties while providing undulation free line and levelled walls with superior finish.

What Is Gypsum Plaster?

When dry POP powder is mixed with water it hardens. This material which can be applied over brick, block or concrete surface to form a smooth surface is called gypsum plaster.

Earlier, a 6 mm coat of gypsum plaster (termed as POP punning) is usually applied on the top of cement plaster to give a smooth finish to it before painting. This is a two stage process and involves various elements like sand, cement and water which has to be mixed onsite. This process is slowly being replaced by a direct application of single coat of gypsum plaster. In gypsum plaster, ready made POP powder is mixed with water and applied directly on the wall.

Gypsum Plaster can be applied directly on any brick, solid or hollow blocks, AAC blocks and plaster boards. Gypsum plaster has good insulation properties, fire resistant and impact resistant. Also, gypsum saves a lot of time during construction and has superior finish. These properties have clearly drawn attention of real estate builders and contractors towards choosing gypsum plaster over traditional cement plaster.

Benefits

For Builders And Developers

1.Green material.

2.Shrinkage crack free surfaces-smooth finish.

3.High productivity-faster work(Reducing plastering time by 70% when compared to conventional sand cement plaster+POP method).

4.Gypsum plaster light in weight, therefore reduces the load on structure.

5.Cleaner Sites-direct application of bagged product-requires no water curing.

6.It has no appreciable chemical action on paint and does not cause alkali attack.

For End Customer

1.No shrinkage cracks on walls and ceiling.

2.Reduction in the time required for plastering and this in timely possession of homes.

3.Perfectly lined,levelled ,smooth walls.

4.Saved electricity for air conditioning as gypsum has low thermal conductivity.

5.Alteration and maintenance is very easy.
