Tiling

Can I tile over very thin patches of adhesive left on wall or do I need to prime the wall first?

I have removed the tiles in my kitchen. The walls are mainly plasterboard with skim of about 1/8 inch. A small part in the corner is ply wood. I am able to get the remaining tile adhesive off fairly easily using a heavy duty 4 inch scraper. I am finding there are very thin patches of adhesive left on the wall. They are so thin that they do not affect the level of the wall in any way. Can I tile over these or do I need to get them off or do I need to prime the wall first? Thanks Albert for taking the time to give me valuable advice. Much appreciated. Mike
