Tiling onto a bitumin floor?

[Jezza]

I am about to tile my kitchen floor&nbsp;which has a bitumin covering using porcelain tiles. The bitumin is in very good condition, clean &amp; dry.<br><br>I've been able to learn from advice given in previous threads rightly or wrongly that bitumin can be very adhesive&nbsp;resistant to cement based adhesives and that I need a flexible porcelain tile adhesive. Is this correct?<br><br>Secondly the floor needs a little self leveling compound in one small area, again does this need to be a latex/flexible compound?<br><br>And thirdly, with the bitumin being in good condition do I need to apply any sort of primer/sealer to the floor before I start any work on it?<br><br>Would be grateful of any advice thanks.<br><br>

Thanks for the responses. So it appears the bitumin needs some sort of sealer to help it with adhesion?

Thats Right

Can anyone please recommend a suitable primer/sealer I can use to treat the Bitumen with first?

Is the stuff hard, black, almost shiney? If so its most likely to be mastic asphalt. I'd thoroughly clean the floor, let dry and then fix with Rapidset or Rapidset flex.

I once found a floor with a bitumen layer. it was hard and didnt seem to move, but i ended up ripping the lot up. id check to make sure it down firm 🙂

I have started to use Mapei eco prim grip which is expensive but is a really good primer,I have use it on bitumen floors with no hassle.
