Eco prim grip and liquid waterproofing - TilersForums.com

[Pinkybee]

I was wondering if it’s possible to use Eco Prim Grip either under or on top of a liquid waterproofing membrane (Mapei)?
i was sold Eco Prim Grip and told I could use it over my waterproofing membrane before tiling at the shop, however I haven’t found any information online to back this up.
I’m tiling onto a concrete substrate and fiver cement boards on the walls.

thank you in advance

you don't need to use the prim grip, just use decent adhesive.
