What is the primary use of IS 136 paint?

It is intended for manual brushing application on curbs, speed breakers, traffic islands, and minor marking works where machinery isn't viable.

What testing standard is used alongside this code?

The IS 101 series (Methods of sampling and test for ready mixed paints and enamels) is extensively used for the actual testing procedures.

Does this standard cover spray-applied road marking paint?

No, this is specifically for brushing application. Other methods like spraying or hot-applied thermoplastic materials are covered under different specifications (like IS 164 or MoRTH specs).

Practical Notes

For main carriageway traffic lines, thermoplastic markings have largely replaced this brushing paint due to higher durability and retro-reflectivity requirements.

Ensure the road or curb surface is completely dry, free from dust, grease, and loose particles before application to prevent peeling.

This paint is not recommended for application over existing thermoplastic or incompatible solvent-based markings.
