What is the average coverage, also can this be used on porcelain slabs

It can be used on porcelain, for a thicker slurry, I'm getting 35m²

Can this be used to prime the underside of sandstone paving slabs for a patio prior to bedding them on the mortar?

It is a must on Sandstone, otherwise the cement will leach thru to the slab face.

What sort of coverage can we expect for patio slab installation

I'm getting roughly 35m² with a 2.5-1 slurry mix, I prefer a slightly thicker slurry (25lt)

whats the mix ratio or can you use neat?

I use it neat as an additive in cement or mixed with kiln dried sand as a primer for plastering
