Self adhesive vinyl floor tiles on leveling compound floor, should i PVA seal floor first to help adhesive?

my kitchen floor has had all the ceramic tiles taken off, and then i put the floor leveling compound on to the floor to level it off





i read the instructions on the box of tiles and it said that it should be clean dry and free from dust





the thing is the leveling compound as much as i sweep it it stays dusty





so i dont want to keep trying to stick the tiles to it and end up them not sticking properly





so i thought i would either PVA and water seal the floor first





or get some sort of extra adhesive and put some on the floor just for extra stickiness





the reason is i tried to stick one of the tiles down but it just didn't seem to stick at all i easily lifted it up


thanks for your help

I have never used self adhesive tiles before. when we put down vinyl flooring, I sanded the levelling compound then vacuumed %26amp; damp mopped it.when it was dry, I spread out the glue %26amp; put the vinyl down. It hasn't budged yet.Self adhesive vinyl floor tiles on leveling compound floor, should i PVA seal floor first to help adhesive?
I put in vinyl tiles about a year ago





I used the epoxy additive with the leveling compound and had virtually no dust once it had set up





without seeing your floor, was your leveling compound mixed too dry allowing it to ';break'; up now that it is dry?





I then leveled out any ridges in the leveling compound, set my tiles and they haven't moved
