DIRECTION OF USE:

SURFACE PREPARATION & SUBSTRATE CONDITION: for New Concrete Surface : Ensure that the concrete surface is cured for minimum 3 months. Preferably the surface has to be prepared by light blasting. In case, blasting is not practical, wire brushing/ power tool cleaning has to be adopted to remove laitance and other loose particles, followed by etching the surface to get a good profile by treating white dilute (10%) Hydrochloric Acid. Remove acid and contaminants by liberal wash with Fresh water. Ensure that acid solution does not retain and penetrate through the joints of the concrete surface. Allow the surface to dry thoroughly before applying primer

For Old Concrete Surface: Remove the surface contaminants like grease, oil etc., by solvent wiping or by 10% caustic solution. Preferably the surface has to be prepared by light blasting. In case, blasting is not practical, wire brushing/ power tool cleaning has to be adopted to remove laitance and other loose particles, followed by etching the surface to get a good profile by treating white dilute (10%) Hydrochloric Acid. Remove acid and contaminants by liberal wash with fresh water. Ensure that acid solution does not retain and penetrate through the joints of the concrete surface. Allow the surface to dry thoroughly before applying primer. For Metal Surface : New hot-rolled steel: blast cleaned to min Sa 2.5 of Swedish specification.

MIXING Stir the base and hardener separately. If settling is observed in the base or hardener, loosen the settled material with the help of hand stirrer followed by power driven stirrer for quick homogenous mixing. Mix hardener gradually into the base under continuous stirring as follows:

Mixing Ratio Base : Hardener 15 minutes (by volume) 2 : 1 Pot life at 30 C 45 minutes

Note:
1 Concrete surface should be thoroughly dry before application of primer and has a major influence on the performance.
2. Staroxy 103 MOT solvent free epoxy primer with moisture and oil tolerant is recommended for priming the surface before applying of Stanrose SLR 150 - 2000
2. Stanrose SLR 150 - 2000 Epoxy coating/Flooring is recommended in the radioactive area with a varied DFT of 250 to 2000 microne thickness as per the requirements.

Storage : Storage Store in a cool, dry place. Store in accordance with local regulations. Packing : 20 litres.

safety precautions
As a general safety measure, inhalation of solvent vapours or paint mist and contact of liquid paint with skin & eyes, should be avoided. Forced ventilation should be provided when applying paint in confined spaces or stagnant air. Even when ventilation is provided, respiratory, skin and eye protection are always recommended when spraying paint.
