Perma Shield



Perma Shield is a straw colored liquid which has excellent waterproofing and protection properties. Perma Shield is effectively used in arresting nagging leakages and dampness from walls and protecting exposed reinforcements. Perma Shield is flexible upon curing and it forms a membrane coating on the applied area.


  • For waterproofing terraces.
  • For arresting rising dampness.
  • For Protection of exposed reinforcing steel rods.
  • For water proofing leakages from toilet units and sunk slabs.
  • For water proofing damp walls.
  • As an effective paint additive.
  • For waterproofing porous plaster surfaces.


Surfaces to be treated with Perma Shield should be cleaned free from oil, grease and loose particles. All laitance and loose particles should be removed by wire brushing or mechanical scrabbling. All undulations and cracks should be made good using Perma Crackfill or Perma Rapid Repair system. In case of badly honeycombed surfaces, give a layer of screed or plaster to make it worthy to receive the treatment.

The system consists of application of 1 or 2 Barrier Coats depending upon severity of problem. In severe cases apply 3 Barrier Coats. Plaster immediately where desired.

  1. Seepages and dampness through walls.
  • Remove the entire plaster.
  • Apply one coat of plaster and cure it for 7 days.
  • Apply one coat of Barrier coat and immediately complete the second coat of plaster and cure normally.
  1. Leakage from sunken slabs of toilets.
  • Stop the use of upper floor toilet till the dripping stops.
  • Remove the plaster or scrape the concrete. If the surface to be applied is concrete only which is sound then use the surface directly.
  • Apply two Barrier coats and plaster the surface immediately.
  1. Terrace waterproofing.

  • On the prepared terrace surface apply two Barrier coats or one Barrier coat followed by Plaster or IPS.
  1. For protection of exposed reinforcing steel.

  • Clean the rods and apply two Barrier coats.
  • Perma Shield dramatically modifies coloured cement paints and white cement used in painting. Perma Shield is added along with water in the powder paints at a dosage of 5 litres per 50 kg of powder paint or white cement.


When the two components i.e. liquid and polymer modified cementitious powder is mixed a smooth consistency slurry is obtained. This slurry when brush applied on the surface to be treated forms a flexible film which has very strong adhesion to the applied surface. The film is totally waterproof and resistant to chemicals and pollution attacks.
