  1. Chicken lattice ought to be fixed firmly at the joint of brickwork and RCC. Additionally guarantee the cover of in any event 100 mm on the two sides 


  1. Cement and block surfaces need to be appropriately relieved (applying water on surface) prior to applying gypsum plaster. All Brick work surfaces must be relieved appropriately for at least 7 days 


  1. RCC surface must be checked for any imperfections like nectar brushing Dressing must be done whenever needed before utilization of plaster material 


  1. All openings and breaks on the outside of the block facade ought to be fixed prior to plastering 


  1. Hack the substantial surface to make better holding between gypsum plaster and substantial surface. Then again, holding specialists (like Bond-it by Saint Gobain) can likewise be applied. 


  1. Guarantee that every one of the electrical channels and plumbing lines are put inside the block work (If they are disguised). 


  1. Guarantee that the RCC surfaces are liberated from covering oil, free materials or some other specialists 


  1. Different extension and withdrawal of RCC and block/stone brick work could cause stresses and now and again partition. To lessen breaks, guarantee chicken lattice (typically 20 gauge) is introduced at block and RCC interfaces, around entryway outlines, around window casings and opening for electrical and plumbing lines. 


  1. Check the verticality of the divider surface utilizing plumb level and eliminate undulations, assuming any. 


  1. Clean water on both block and RCC surfaces ought to be applied 10 minutes before plaster application to control the attractions.

  • Drawn out or rehashed openness to dampness may cause a deficiency of solidarity or potentially grip. 


  • Painting work ought to be just begun once the surface has got totally dry. 


Suggested Thickness Of Gypsum Plaster 


  • Gypsum Plasters can be applied from 6mm to 20mm in thickness. 


  • We suggest a base thickness of 6 mm gypsum plaster to keep away from breaks and debonding 


  • In the event that in excess of 20 mm thick of plaster builtup is needed for a divider, at that point we would prescribe to initially go with a scramble layer of cement and sand plaster for a thickness of 8-12 mm and afterward get done with gypsum plaster for the leftover thickness (which ought not be under 6mm). 


Suggested Finish For Gypsum Plaster 


  • Gypsum Plaster ought to be done to a decent level of perfection prior to painting. The surface is normally sand papered (not with emery paper) to give it a further smoother finish. 


  • Every flat line and surface ought to be tried with a level.
