Plaster Proof


  • The admixture gives your plaster workability, durability, quality and is economical too.
  • Both the richer and leaner cement-sand mortar mixes have their own merits and demerits. Rich mortar mix has a better bonding effect but it is associated with severe shrinkage cracks upon drying. Leaner mixes with less cement content exhibit less shrinkage and fewer shrinkage cracks in the plaster but they show a poor quality of adhesion to brick work or RCC which results in hollowness.
  • PP 149 is developed to get over the demerits and deficiencies of both richer and leaner mortar mixes.
  • Work ability - Plaster can be spread easily, rapidly and could cover more areas at one go.
  • Provides cohesiveness to cement-sand mortar.
  • Improves workability, durability and strength of mortar.
  • Improves bonding of plaster over the cementitious surface.
  • Reduces shrinkage cracks.
  • Eliminates efflorescence.
  • Minimizes shrinkage and cracks.
  • Reduces rebound losses.
  • Allows the plaster to breathe.
  • Durability is increased due to air entrainment.
  • Segregation, bleed and there after honey combing is prevented.
  • Surface finish of concrete and plaster is improved.

Internal and external wall plastering.
