Using builders sand - Laying slate on builders not sharp sand

[Timbaland]

Hi Everyone,

First time poster.

After wacker-playing a hardcore base I started to lay the slate slabs on soft builders sand. A little person in the back of my mind says I should have probably used sharp.

The question is, can I keep going and get away with it or should I rip them up and start again or is there another alternative I don’t know about.

Thanks in advance!

NO rip it up
flags must be laid on a cementious mix 6 grit sand and 1 cement,with water to suit
plus a bond bridge
