The laying instructions from the supplier for the porcelain tiles I plan to lay say I should apply slurry primer to the back of the tiles and also to the mortar bed they are laid on. I am not sure how to apply the slurry to the mortar bed and the supplier just referred me to the suppliers of the slurry who only mention apllying to the back of the tiles.
Any ideas on the method of applying slurry to the mortar bed?
