SBR slurry- correct mix please?

[Plumbing Tiler]

Hello all, hope you are all keeping well and busy!
Just a quicky, I have a kitchen floor coming up to tile with some bitumen left on it from I'm guessing when it was previously parquet floored. As I mostly do bathrooms I've not come across this problem before so I need some help please!
It has dips and bumps and is far from flat so I was going to go over it using Weber floorflex then prime and tile but I now realise that SLC is not the best way and that a SBR slurry mix is the way forward, my question is what is the correct mix ratio please, didn't want to google it as I would rather hear it from an experienced expert!
Thanks in advance!

Most people work to a ratio of SBR diluted 1:1 with water and then mixed with approximately 30% by weight of adhesive. I often go slightly more on the SBR, then just mix in the adhesive until a smooth consistency a bit like thick self levelling compound

The mix I've always been told is 50:50 no water , so 1:1 sbr and cement or tile adhesive (rapid set ).

 

[Qwerty]

That's why I use more SBR. I do find the water helps it move better though, so personally I do still always use it. The 1:1 ratio is far superior Dave, just a pig to move about

Thanks for the reply Plan Tec.
So you say to use "adhesive" , so you mean tile adhesive then and not cement?, then do you mean to use the mix to fix the tiles instead of just adhesive on its own, I was under the impression that you used the mix like a SLC then when it dried you then tiled onto it or have I got the wrong end of the stick- quite probably lol!

 

[Qwerty]

Cement (bagged) tile adhesive. You roller the slurry on, not poured like SLC

Cheers Geoff! I'm with you now, so its best to use a rapid set adhesive to aid drying then I guess?.......So is actual cement a no-no then, cement based addy is the best way?

 

[Qwerty]

Rapid is best. I have used normal cement in the past but tile adhesive is smoother and in the back of our vans!

Lovely job thanks very much Geoff, that's me sorted now then! Lesson learnt for today!

or to save time you could prime with the new primer from TM prime+grip

Have you used that? What's it like?

Hi Geoff,
Are you going to Topps trade roadshow @ Poole tomorrow night?, I don't use them myself anymore, used to until CTD opened but thought it might be worth a look?

Evening mate. Afraid not

 

[Plumbing Tiler]

No worries, just thought I'd ask as I see you're based nearby, the Wife gets bored of me talking tiles all the time you see so I really need a tiling friend lol!

 

[Lee@emctiles]

Yep, weve demod it Dan, all singing and dancing primer, i can see it being another good TM product.

Looks nice and thick.

Will other adhesive firms still guarantee their adhesives and whatnot if you use a primer you have a preference for?

 

[p4ulo]

So do you slurry coat as a proper job primer, then SLC still on top?

I went to the TOPPS roadshow tonight. I wish I had some money cos they had some great offers. Top of the range FEIN in a proper case with loads of attachments...£193.75!!!
Bugger.
Oh well, got some silly freebies, and a tub of Green Star! And I'm stuffed full of free food and a cheeky tin!!
(Trouble is a tin on a school night only ends one place....I'm down the pub!)

 

[Qwerty]

@p4ulo .....slurry for problematic substrates such as bitumen covered screeds or a surface that requires a key to tile onto. I often SLC after slurry coat to get an old screed up ready for tiling

Nice prep Jeffy, but what ghastly tiles!
(Another area of deep mystery and witchcraft suddenly makes sense! x)

 

[Dan]

Doesn't the SLC on its own look so much cleaner?!

 

[Dan]

Good for an army barracks BBQ area those are.

Old 16th century cottage boys. The limestone flags had only just been sealed before grouting. They dried lighter to be fair

Oh actually, no they didn't!.

Gosh are they Limestone Flags......
they look like a terrible porcelain tile grey with light grey over the top....like a load of muddy footprints on a clean floor!
I'm sure they look much better in the flesh Jeffyboy. x

EDIT - cos he's just put another picture up - they look better in that piccy, must be the light!

 

[Dan]

Do they heck they're the worst tiles I've ever seen I think!

What designer stood back and said, yeah, lads, we've cracked it. All tiles will follow in our footsteps now.

 

[Qwerty]

They certainly weren't my cup of tea!

 

[Plumbing Tiler]

Lovely job Geoff, thanks for the pictures! But I've got to say they are without a doubt the worst looking tiles I have ever seen, and I mean EVER lol!
