tile over old black adhesive?

[ColJack]

I'm doing my kitchen floor this week and have taken up the old vinyl tiles as a few were missing bits, and a few missing entirely ( under the old units )..
this has left me with a black tarry like substance on the concrete floor which I assume was the adhesive for the vinyl tiles..

do I need to do anything to this before tiling over it ( ceramic tiles )?

as long its sound and all loose bits gone, and of course it isnt overly high, just tile over it.

the tile place gave me a little bottle of something white when I fetched my tiles and adhesive and grout..
not sure what it's for...

do I mix it in with the adhesive or paint it over the black stuff before I slop the adhesive on?

what does it say on the side of the bottle?

whats it called?

it may be a flexing agent that you use mixed in with the adhesive and grout, i wouldnt reccomend this if it is, id use flexi adh and grout rather than a mixer.

just my onion.

You usually get one of those in the curry house when you tell em that their Balti is dodgy.

it's "something"bond.. it's in the car and I can't be bothered to go out to read it..

 

[gcol]

Then I can't be bothered to tell you what it's for.

i read that last night what the fella put and thought exactly the same thing.

hiya ive come for advice andhelp, cant be as*ed to make the questions clear, where am i going wrong tho?

 

[ColJack]

oh be fair. it was 11.22pm and I was in my jammies and I didn't fancy going out in the dark and rain to read the side of a bottle..

went out this morning and it's flexibond..

I never asked what I was doing wrong. I just wondered what the little bottle was for as they didn't explain..
I told them the area and what tiles I wanted, picked a grout colour and told them it was a conctrete floor and told them about the black stuff..
he scribbled down a list of stuff and that's what I collected monday ( had to order the tiles in )..

 

[jefoss]

its just A,N. other additive to add to the adhesive and grout. to be honest if you need flexi adh get flexi adh.

i dont like the additives they dont work as well as the real thing.

but im sure someone on here will contradict what ive said and say somehting similar too" they wouldnt sell it if ti didnt work" etc etc


sorry im done now!

 

[ColJack]

I thought that flexi adhesive was just for wooden floors, why would it need to be flexi on a solid concrete floor?

 

[jefoss]

maybe they beleive from your description of the black stuff that it may move. hence flexi.

Have you ever tried moving a whole floor of tiles? You should have used Ditra to separate (decouple) the floor from the tiles. Then the floor can do whatever it likes as the Ditra simple sits above it.

 

[ColJack]

thank you for your help, I'll see how it goes...

 

[jefoss]

Have you ever used Ditra mat Jeff? No? Didn't think so. Dinosaur.

ive not used a steam engine either. does that make me a dinosaur too?

nice googling btw joe
