Do I need to SBR over SLC?

[Rodduz]

Hi,

Do I SBR over such before laying ditra then tiling?

Have some bostik cementone so was going to prime it? How essential is getting the ration of the primer if I do need to prime it?

Thanks

I always prime, it makes the adhesive more workable I find the SLC a bit dry. 3 to 1 water to primer or as on the instructions.
But no primer is ok too.
