Alternative to kiln dried sand

[Dusty2017]

Hi,

I'm laying marshalls tegula pennant grey blocks and was wondering if

"Dansand No Weed Block Paving Sand Stone Dust" as found in Wickes

is a viable alternative to the kiln dried sand?

Or should I vibrate in some kiln dried and then top up with the stone dust to give grey coloured joints?

Thanks in advance.

Sorry just noticed a previous post on the same matter guess it is ok just a more expensive route.
