Hello all!
I've recently knocked through my kitchen and diner.. It's been a hell of a job after a flood from the bathroom upstairs before we bought it.
New ceiling, total rewire, ducting for island hood and all walls replastered.
We're finally ready for mist coat etc. When thats done I'm looking to lay polished porcelain 600x600's from tilehq (niro's in white, already purchased).
-on that note 3mm gap minimum is stated on the niro granite boxes .. which i'm going with as we want minimal grout if poss.

The floor is a mix of concrete from where the old wall was and a gas pipe we had to move, and very old plastic tiles on bitumen.



I've lifted a couple of tiles and done a close up. The bitumen looks like only 1-2mm thick but what's the best plan here please? The far end of the room (the diner previously) has a thicker coat of bitumen (pic on right of the two below).
I've seen some old posts but wondered if there is any up to date soloution. Apologies if I've missed something in the forum about same.

It's been suggested to me to use "norcros prime bond sbr" - never used anything like this before but bought a litre while I was in a tile shop in Brum.
I've got keraquick from TileHQ in grey and ultracolour plus in white.

As soon as we're painted up (the left wall in the main room shot has only just been plastered this morning so I'll leave mist coat a while yet) I would love to tile this floor.. just dont want a horry storry in 18 months like I've seen elsewhere of tiles coming back up.

Thanks in advance for any help at all

In an ideal world you would remove the bitumen residue mechanically.
In the real world remove any loose bits, prime with SBR and tile away with SPF addy.

Slurry coat of SBR and SPF for me.

Remove loose.

As above. Slurry coat with brushable mix of SBR/Single part flexi powder

Thanks guys. So not the keraquick? And sbr.. Straight or diluted?

Slurry coat is 50/50 neat mix..

Keraquick is fine

Brill thanks just brushed being sufficient?

If we managed to fit in our budget heating the floor... Would such as ekoboard i've seen on uheats go straight on this? What dictates what thickness to buy if anything bar level of insulation?

Thanks mucho for all your help so far!

Ekoboard ? thats the unsurfaced stuff isnt it ? as opposed to the hard surfaced type of boards. I personally dont like the idea but I was told they were suitable.
Minimum thickness for Marmox type boards would be 10mm, thicker the better really.

I spotted them on u-heats sponsor link top left. Theyre purely for ufh.

Yeah I know but it just doesnt seem right to tile on to a soft surface IMO.

Ok thanks will lookup marmox

Foortunesss lol for 20m2. Should wire be ok straight onto the slurry?
