Surface Preperation :
Steel : remove grease, oil & other contaminants preferably by using degreasing solvent. Blast clean to a minimum of Sa2 ½ Swedish std SIS 05 5900. For severe corrosion, blast to Sa 3 with a surface profile not exceeding 65 microns.
If blasting is not practical, make full use of mechanical tools along with manual chipping & wire brushing to remove loose rust & scale to st 2 swedish std SIS 05 5900. Excessive burning of steel is to be avoided. Thoroughly dust down all surfaces. Best results can be achieved if the manually cleaned surface is primed with protectomastic- self priming surface tolerant coating; otherwise treatment with metal conditioning solution will also produce satisfactory results.
The surface should be clean & dry before application of primer coat.


Concrete : new concrete- ensures that the concrete is cured for a minimum of 3 months. The surface is to be made rough & free from laitance & other contaminants by sand sweeping.
Old concrete- removes all salt deposits from the surface by water jet washing. Light sand blast the surface to remove all loosely bound coating & roughening up to firmly adhering coating to ensure anchorage with recommended system. Ensure all dust/ other particles are fully removed by suction or air blast & the surface is fully cleaned & dry before application of paint.
In non critical areas where blasting is not possible, water jet washing & hard wire brushing are minimum requisites.


Application :

  • Stir base thoroughly & then mix 4 parts of base & 1 part of catalyst by volume to uniform consistency. Allow the mixture to mature for 30 minutes & stir again before application & during use.
  • Brush / Roller: add up to 5% thinner if required during application.
  • Conventional spray: add up to 15% thinner depending on conditions. Use only standard equipment at an atomizing pressure of 3.5-4.9 Kg/cm2.
  • Airless spray: apply preferably without thinning. However up to 5% thinner may be added if absolutely essential depending on conditions. Use any standard equipment having pump ratio 30:1. Tip size 0.38-0.43mm.Tip pressure 110-160 Kg/cm2 .

Note :

  • Use off the mixed paint within the specified pot life period.
  • Do not apply when temp.falls below 10Ë C or rises above 50Ë C & when relative humidity rises above 90%. Do not apply during rain Fog or mist.
  • Brushes & spray equipment should be cleaned with thinner otherwise equipment is liable to be damaged.
