Application methodology : Surface Preparation

  • The background to be plastered should be thoroughly brushed with a broom to be free of all particles & background dust and clean traces of mould oil.
  • In case of hacking, provide 50 hacks (should be minimum 10-15mm).
  • It is recommended to pre wet th surface so as to achieve more spread and higher coverage.
  • Mix one coat plaster to water, use a mixing rod for thorough mixing and avoid lumps and unmixed residues.
  • Water to plaster ratio (1 part water : 2 parts of plaster) should be maintained to have a good cohensive workable mix.
  • Mix one coat plaster as much as required depending upon the immediate scoop of work, partially unused material to be kept well secured in dry place.
  • Once the mix has began to set, additional water should be added, as performance properties of one coat plaster will get altered, thus affecting workability, cohensive, adhesion and strength.
  • Avoid using a wet brush on the finished surface as that would leave permanant brush marks and thus spoil the surface.
  • A single coat should not exceed 13mm in thickness. If at all thickness more than 3mm is required, plaster should be applied in multiple coats.
  • After complete drying (usually takes 72 hrs depending on the thickness & weather conditions), the plain smooth levelled surfce is ready for painting.
