How cold is cold? So long as the bitumen is still workable, all you lose is some time to spread the colder stuff around. Hot applied also fills up the gaps better, but has a vapour issue alright.

How do you think it is "easier?"

* This is a Refrigerated liquid storage tank right? what is the design temperature ?


- Is this cold bitumen paint ? Similar to the following :

If so, these type of products waterbased and service temperature should not be less than [°C] -5 ..

What is the ambient temperature and design temp. of liquid content ? Is the slab elevated ?

You may choose to provide more details to get better responds..

Hot service is more common?

But yes could be either.

Tank is a chilled water storage, 4 degree Celsius at lowest.
The cold bitumen paint I am referring to is this.

Ambient: 38 deg C, design: 4 deg C, slab is 4 inches above ground.

"Easier" as in no need to find a bitumen boiler and not having to take the risk of getting burnt from the hot tar.
Anyway, I managed to get some input from the supplier, they prefer the hot pour method.
I guess the reason might be for hot pour, it will be able to fill deeper gaps, and no 'cold joint' in the event the area cannot be completed in one go.
