For a traditional, full mortar bed installation, we recommend using a Priming Slurry. What gives porcelain such superior properties including stain resistance is the fact that the paving is non-porous.
Because of this low porosity, the porcelain requires a priming slurry to be applied to the underside of the flagstone, before being laid onto the mortar bed, to create an exceptional bond between the two.
