Tips & Advice

Surface Preparation

  • Ensure that the surface is clean and free from grime, dust, flakes, grease etc. For old surfaces, remove all loosely adhering particles, powdery materials or defective paints by thorough brushing, scraping and water jetting, if required.
  • For best results and for surfaces that remain powdery, friable or chalky even after thorough preparation, application of topcoat material as primer with 1:1 dilution in water as an extra coat, is recommended.
  • For algae & fungus-affected area, application of Pre Treatment Coat is recommended.
  • On horizontal surfaces, it is recommended to do 3 coats of topcoat material.
  • Allow new surface to dry out completely. It is recommended to allow at least 12 weeks as the curing time for new masonry surfaces. Please ensure pH level between 7 & 9 before painting.
  • Fill up all minor cracks and defects with cement and sand mixture in the ratio 1:3. Avoid application of putty or filling compound.
  • Exterior Sealer E900 should not be applied to the surfaces or substrates which are exposed to continuous seepage or dampness.
  • For best adhesion performance, the moisture content in the wall should not exceed 10%.
