UTC Gypsum Plaster is a processed gypsum-based internal wall covering material which is produced as a result of calcinations of the raw gypsum in an automatic kettle under controlled temperature. The product is suitable for walls made of AAC blocks, RCC and other types of blocks/bricks. Traditionally, internal wall plastering consisted of a 2 step process of sand-cement plastering finished with POP punning. With UTC Gypsum plaster, the tedious 2 step process is simplified by directly applying a single-coat layer of our product, resulting in an efficient internal wall plastering, with a superior finish, better work-ability and higher coverage.
Even history shows the usage of gypsum as an internal plaster as found in the Pyramids of Giza in Egypt, which were lined with gypsum stucco plaster centuries ago and are still intact, which is proof of the durability and performance of this product. Today many of the modern constructions around the globe use gypsum-based plasters in their interior wall plastering work.

Cost Effective :

A single coat of Gypsum Plaster can replace s/c plaster saving cost of material and labour. Also due to the evenness and smooth surface finish, it minimizes the quantity and application time requirement of Putty coating.

Availability :

Unlike sand which is used for conventional sand cement plaster, UTC Gypsum plaster is easily and legally available across the country at all points of time.

Minimum Cracks :

Shrinkage cracks are minimized as premix plaster raw materials are tested and accurately mixed with specific particle size and quantity.

Single Coat :

Due to the free-flowing nature of the product, the preparation (mixing water and UTC Gypsum plaster) turns out to be a easy application paste which results in the required finish in one single coat.

High Strength :

High compressive and tensile strength increases masonry strength and load-bearing capacity.

Exceptional Coverage :

Addition of additives and certain chemicals during the product processing lowers the overall density as a result we get higher coverage per kilogram.

Min Cracks :

The material does not go through shrinkage or expansion process once it has been settled, which avoid shrinkage cracks.

High Strength :

Gypsum as a raw material consists of high compressive strength as a characteristic, being the major raw material for the plastering product makes the material strong in terms of bonding.

Water Saver :

Conventional plastering methods require curing in the s/c walls as a procedure to complete the application, whereas Gypsum-based plasters are self-setting.

Minimum Wastage :

The wastage caused in the conventional site mix process while sand sieving and mixing material is totally avoided.

Easy Application :

UTC Gypsum plaster is a premix product consisting of processed gypsum containing additives and chemicals, during application only water needs to be added and mixed. The paste formation gives a butter flow feel easing the process of application.

Availability :

Unlike the uncertain availability of raw river sand, premix bags are available round the year.

Thermal Insulation :

The material has low thermal conductivity making the plaster a good climatic insulator, keeping the internal temperatures pleasant at lower energy costs.

Reduction In Dead Load :

Cutting off the need for sand cement plaster (a high density plastering material), the overall dead load of the building structure is reduced. Additionally, UTC gypsum plaster also consists of certain additives/chemicals which make it light in weight compared to the conventional plastering material.
