Method of application

Surface Preparation:

ULTRASHIELD-XT should always be applied over a recommended anti-corrosive primer. The primer surface should be dry and free from all contamination and ULTRASHIELD-XT paint must be applied within the overcoating intervals specified.

Mixing and Application:

Stir the base and hardener parts separately before mixing them together. Mix hardener gradually into the base container (not the reverse) under continuous stirring. Always mix the full measure as supplied to avoid improper curing issues. A suitable power mixer is recommended for uniform mixing of the product. Continue the mixing for 3-5 minutes.

Allow induction time of 15-20 minutes and then thin down to applicable consistency with required quantity of solvent. Mix thoroughly till the components become homogenous.

Apply the paint liberally with a paintbrush followed by spray, brush rollers. Apply 2 to 3 coats of ULTRASHIELD-XT to meet the desired opacity as well as finish, depending on the shades. Provide min 6-8 hrs. drying interval between the coats.


  • Once base is mixed with hardener, paint should be consumed within pot-life.
  • Do not apply when substrate surfaces or ambient temperatures are below the dew point.
  • Material and the substrate temperature should be above 10°C and below 50°C before use
  • Application on direct sunlight and windy situation may affect the paint performance Cleaning
  • Clean all tools and spillage of paint with water immediately after application.
  • Use proper protective equipment while handling. Contain solvents, use adequate ventilation during use. Avoid direct contact with skin and eyes. In case of contact, wash thoroughly with plenty of water and consult a physician if necessary.
