Envirobase High Performance Internal Repair System is designed to provide a simple and efficient process for repairs involving a specific matt interior colour, or low gloss versions of the external colour.
Direct application to electrocoat produces a groundcoat colour to accurately reproduce the original finish on internal parts. At the same time it provides a coloured wet on wet layer that can be topcoated to reproduce the original external finish, thereby removing the need for undercoating.
Envirobase High Performance Internal Repair system has two modes of use. Internal colour formulas matched to dedicated OE internal colours are provided as part of the PPG colour retrieval system. Alternatively any waterborne colour can be converted to Internal Repair mode for use in many repairs where internal colours are low gloss versions of external areas.

Spray Viscosity 18 - 21 secs DIN4 / 20'C
Spraygun Set Up: HVLP Spraygun 1.3 - 1.4 mm – SATA WSB Recommended | Spray Pressure 1.3 -1.8 bar
Number of Coats: Apply one double coat or 2 single coats to opacity to give a dry film thickness of 10 - 25 microns.
Flash Off at 20'C: Between Coats: Ensure that each coat is fully flashed off before overcoating. Blow dry using SATA blower. 5 minutes or until matt appearance between coats if using single coats. Activated Internal repair basecoat should not be left uncoated on external areas.
If required for external areas: PPG recommend the use of a matted clearcoat to seal the basecoat.
