marmox as floor insulation , what adhesive???

[spreadandlay]

hi,

i am putting 20mm marmox down onto screed before i lay UFH and tiles, do i need to use flex adhesive (expensive) or could i use insta stick foam (cheap) ?

Do i need to pva the screed before applying adhesive as there is patch of bitumen?

many thanks for your time
