Application Guidlines

Surface preparation

    Surface must be free from dirt, grease, oils and any other foreign substances. Any flakes of old paint or powdery residues must be scrapped off and cleaned thoroughly by sanding using an emery paper. Algae and fungus on walls to be removed by high pressure water wash or coir brush and apply Bio-Wash fungicidal solution if needed. Fill all cracks with suitable crack filling chemicals prior to primer application. Dampen the surface before application of primer, but should not apply on standing or running water. After one coat primer apply suitable putty to remove the undulation on the surface. Once the putty dries sufficiently hard smoothen the surface by sanding with emery paper No. 320. Apply another coat of PRIMER W2k on the sanded surface and allow it to dry for 3-4 hrs prior to the application of xxx finish coats.

Mixing and Application

    Stir the base and hardener separately before mix them together. Mix hardener gradually into the base container (not the reverse) under continuous stirring. Always mix the full quantity 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 10 minutes and then thin down to applicable consistency with required quantity of potable water. Mix thoroughly till the components become homogenous. Apply the primer liberally with paint brush followed by rollers.

Cleaning

    Clean all tools and spillage of paint with water immediately after application.


Precautions & limitations

  1. Once base is mixed with hardener, paint should be consumed within pot-life.
  2. Do not apply when concrete surfaces or ambient temperatures are below the dew point.
  3. Material and the substrate temperature should be above 10°C and below 50°C before use
  4. Application on direct sunlight and windy situation may affect the paint performance
