first forum advice on floor tiling

[thebluemax]

Hi all
have been lookin at your forum for advice, but now I feel a proper questiion coming on....
I have a 9 square metre kitchen that needs tiling, I have a concrete subfloor that has previously had marley type tiles on it (1965 house) stripped all the tile off and I an left with a small residue of bitumin ( I think) left on the concrete, I an putting down 6mm thermal boarding and then overtiling with 9mm 600x300 ceramic tiles.
Can I just stick the board down with my flexible quick set adhesive and then put tiles down on top, or will the adhesive not stick to the bitumin residue left over from the tiles ?
advice in black and white needed please.

Many thanks.

Do you have any pics you could upload for us to the sub straight please.

If you have a bitumen subfloor it will need to be primed with weber pr360 with 5 parts primer to 1 part water. You will need to let it dry which can take hours. Then use flexible adhesive.

Save the money and mix up a SBR/ SPF rapidset slurry and paint or roller onto the bitumen

cheers, where can I get this stuff from ? any tiling shop or on line ?

 

[White Room]

Any builder merchants or some tile stores should have it...

Same here.

SBR/Cement slurry.

 

[Kevboy]

Yes SBR for me, you can get it in Topps Tiles.

Hi all thanks for the replies,
Today I bought a 1Ltr of Norcros prime bond from a tile shop, it is water based and he said you can use it neat or diluted,
1. multipurpose
2. SBR
3.Internal & external
4. water & frost resistant

have I bought the wrong stuff ? (he said it was correct for over bitumen residue)

Here is a couple of pics of the floor residue

I would still be mixing it up with SPF rapid to a slurry

if thats a better way then great, exactly what do I mix up and how, also how would I apply it, brush/roller or trowel ? sorry for all the non tech questions, as you can tell I dont tile floors often..lol

[thebluemax]

one other thing guys is...if the floor is running out say 5mm or so is it ok to put the slurry on thicker at that point, or can you re-apply the slurry on top of the first coat if you see what I meen.
cheers for all your replies.

The slurry is traditionally 2 part adhesive to 1 part SBR. I often mix up a water SBR mix (2:1) instead of neat SBR and mix this with the adhesive to a slurry. I personally pour then roller onto the floor.
As for making up height....slurry first, the use SLC :smilewinkgrin:

cheers geof, I'm not good with ratios..so i have a 1ltr sbr, if I use half of this and half water, then add it to my powdered adhesive (how much adhesive to that mix will I need from the bag ? (I have 9sq mtres), or some say mix cement instead of adhesive.
sorry for the daft questions.

No, add the rapid set flexible adhesive to the liquid. Mix a bit at a time until a sloppy slurry consistency is reached, then leave for a couple of minutes, mix again then you are ready to roller it over the bitumen
