Using Going to prime with Tilemaster Prime Plus, mixed 3 part water 1 part primer, so a litre should cover my 30m2. Then use Tilemaster Anhyfix adhesive for the tiles.
Well you are certainly using the correct adhesive, but listen to the advice from @Ajax123 as he's the don when it comes to these screeds. If he advisers mechanically sanding then take heed.
