UTC AAC Ready Mix Plaster is a premixed cement-based solution to substitute for the traditional site mix wall plaster process. The solution consists of processed sand which is graded and distributed as per particle size and proportionately mixed, cement, and water soluble polymers which act as additives. The application method requires mixing of water before application and the mix is ready for plastering. UTC Ready Mix Plaster can be used for both external and internal plastering.
UTC AAC Ready Mix Plaster can be applied on:

  • AAC Block Walls. 
  • Fly Ash Block Walls.
  • Clay Brick Walls. 
  • Stone Walls.
  • Concrete Block Walls. 
  • Concrete Surfaces.


8-10 mm single coat is recommended for internal plaster covering.
Two coats are recommended to cover the external side of walls i.e. Base coat of 8-12 mm and Finish coat of 8-12 mm to get a total thickness of around 18-20 mm, further depending upon site conditions. After Base coat, minimum 2 to 3 days curing must be done before application of Finish coat.
Parameters UTC Ready Mix Plaster Conventional Method
Application Time Fast application Not possible
Quality Consistent quality due to computerized process Manual mixing hence not possible to test every batch
Shrinkage Cracks Minimum shrinkage cracks Significantly high shrinkage cracks
Handing & Storage Easy handling and storage Difficult to keep stock of different material
Wastage No wastage High wastage
Efflorescence Negligable Observed in many cases
Sand Graded Non graded
Rebound Loss Minimum High due to non gradation & bigger sand particle size.


Economical :

It provides smooth finish walls even in a single coat. Hence saves time and cost required for putty coating.

Easy Application :

The material is pre-mixed and only water has to be added on site. This makes the process of plastering much easier and quicker.

Minimum Cracks :

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

Higher Coverage :

Due to lower density and high volume, it covers 15-20 sq.ft./bag with a thickness of 10-12mm.

High Strength :

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

Premixed :

No site mix and blending of powder is required. Only water is to be added.

Consistency :

Due to the manufacturing process and accurate particle size distribution, the premix bags are of consistent quality.

Hassle Free :

No hassle of maintaining mortar ratio, whereas in the conventional method labour and supervision are required to prepare the mix.

Minimum Wastage :

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

Storage :

Easy to maintain stock as equal size packaging in bag form is provided.

Availability :

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

Finish :

Surface finish after application is excellent and equal due to best particle size grading, hence maximizing wall plaster performance.
