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 cracks with suitable crack filling chemicals and allow the surface to dry completely prior to start the painting job.

Mixing and Application

    Stir the paint before application and then thin down to applicable consistency with required quantity of potable water. Mix thoroughly till the components become homogenous. Over-Mixing more than 5 minutes may destroy particles, thereby reducing insulating capabilities.

    Apply the paint liberally with paint brush followed by rollers. Allow the surface to dry for atleast 1-2 hours before applying the second coat.

    After completion of full coating, it should be allowed to cure for 24 hrs. Apply second coat after a gap of 1-2 Hours

Precautions & limitations

  1. Do not apply when concrete surfaces or ambient temperatures are below the dew point
  2. Material and the substrate temperature should be above 10°C and below 50°C before use
  3. 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.
