Can someone please tell me if i should prime plasterboard and plaster with Mapei Primer G prior to tiling with Mapei Kerraquick and if so what ratio to use - the instructions for the primer are unclear it just says 1:1 or 1:3 depending on the porosity of the substrate? Not very clear

Thats not what is says in the instructions - they say for use on absorbent substrates e.g. screed, plasterboard, plaster, plywood. Just not clear what ratio to use
