Tiling over bitumen

[goosergus]

I have Unibond ready mixed "tile on Concrete" adhesive and grout but the area i originally thought was concrete had a small area of vinyl tiles. I removed the tiles but this leaves a bitumen problem.
The tub says not to tile over vinyl but has no reference to bitumen.

A tiler (career tiler) friend said to get rid of the "tile on concrete" cos he had never heard of, or used it and B&Q stuff is **** and for diy'ers (i didnt take much notice of the B&Q comment cos i know uni bond to be a good brand, i think).

He said use "rapid set" as that would tile over anything and hold but the packet of "rapid set" i saw in B&Q said "not suitable for tiling over bitumen."

Clue me up purlease lads (or lasses) cos me old ma is desperate to get her tiling done before her new kitchen arrives.

Thanx in advance

It's very simple - bitumen is not absorbent, so you need to prime it with a product designed for the purpose.

If you visit a tile specialist (i.e. not B&Q) then they will advise you, and they should be able to sell you the correct product.

You can get a product specifically designed to tile over bitumen in the Rapid Set range. It's about £20 though. From B&Q.

Or you can brush over it with some self levelling laytex screed or cement slurry to isolate the bitumen and create a substrate that will be ok for the adhesive to adhere to.
