Global Gypsum G1, one coat gypsum plaster is a replacement of traditional sand cement plaster and is suitable for application on most internal surfaces including brick, block and concrete. Lightweight aggregates like “Vermiculite” and special additives are included to enhance coverage, setting time and workability.

Global gypsum G1 can directly replace sand cement plaster in all the internal plastering application providing smooth and levelled walls.

Benefits & Advantages 

  1. Coverage of 80 Sq meters/MT at 13 mm thickness*No shrinkage cracks
  2. Eliminates two-step process of Sand Cement Plaster and POP punning
  3. Doesn’t require water curing
  4. No shrinkage cracks
  5. Initial setting time of 15 – 20 minutes *
  6. Enhanced Fire resistance ***
  7. Low thermal conductivity keeps room cooler in summer and warmer in winter
  8. Non-combustible (when tested in accordance with BS: 476: part 4:1970), therefore a good form of thermal protection to the building structure.
  9. Use of light weight aggregates in the plaster mix help to improve the Thermal resistance. (Thermal Resistance R = 0.07m²K/W at 13mm thickness)

Mixing instructions

  1. Global gypsum G1 is pre-mixed with aggregate and only clean water needs to be added to prepare it for use.
  2. Mixing should be carried out in a clean tray or bath. Excessive mechanical mixing should be avoided.
  3. Tools and water used in mixing must be clean.
  4. Contamination from previous mixes can shorten the setting time and in turn reduce the strength of the plaster when set.
  5. Water to plaster ratio (1 part of water: 1.25 part of plaster by weight) should be maintained to have good cohesive workable mix.
  6. Prepare plaster mix as much as required depending upon the immediate scope of work.

Note: Once the mix has begun to set, additional water is not to be added, as performance properties of plaster will get altered, thus affecting workability, cohesiveness, adhesion properties and strength.

Application instructions

1. Surfaces to be clean of dust and oil residue before applying.
2. Don’ t applies when temperature is below freezing.
3. Application of epoxy paint is not recommended.
4. Please consult your paint vendor/manufacturer on the correct primer for application
Onto gypsum surfaces.

5. For detailed application, refer to Global Gypsum Plaster Guide Booklet or contact the Customer Contact Centre +919821165575
6. Store inside on a level surface, off the floor, in a dry place protected from the weather.
7. For interior use only.

Note :

  1. As in good building practice, roof, windows and doors should be installed before plastering with Global gypsum G1 (to help prevent dry-outs and ensure consistant setting).
  2. Global Gypsum G1 should not be used in areas where walls are washed with hosepipes, in showers or in industrial type kitchens.


  1. Dissimilar expansion and contraction of RCC and brick / stone masonry could cause stresses and at times separation. To reduce the separation cracks, use of 145 GSM glass fiber mesh (at the junction) is recommended.
  2. It is not suitable for use in long continuously damp or severely humid conditions.

Covering Capacity

The approximate coverage of a 25kg. of Global Gypsum G1 Plaster is:

  1. 10m2applied to a thickness of 3mm
  2. 4m2applied to a thickness of 5 – 6mm
  3. 20m2applied to a thickness of 13mm
