The first time I used an SBR mortar, which would be back in the mid 80s, I worked without gloves, got some on my hands, and while it eventually came off the skin, I had to wait for the nails to grow to get rid of it from them.

my 5ltrs of Cementone SBR cost me £21+vat so I will obviously have a word next time I am in.
I have to say I have had a play with it last week and i'm impressed with the stuff but I have a few Qs if I may.
how much would you put in a full mix(standard belle mixer) for Flagging?
are you better to put it neat into the mix or dilute into a water mix first?
would plasticiser still be required?
would you give the underside of your a flag a wash with the stuff before laying?

remembering what the back of the bottle said when i used it, it was 5-10 litres per 25kg of cement, but i used half that to 1 bag of cement, didn;t slurry wash them but i was bedding copings on a wall, but they stuck like the preverbal sh*t to a blanket

I asked a similar question in this thread
http://ext.pavingexpert.com/cgi-bin....7;st=20
The answer was
For a bond bridge, mix half-a-cup of SBR with enough cement to turn it into a pea-soup consistency slurry. Don;t make too much at once because it goes off and you're only painting it onto the undersides, so usage is slow.
For mixing mortar, 250ml per 5 litres of gauging water will usually be OK for general paving work: we'd quadruple that for bonding work, such as coping stones or step treads, etc.
Coating the underside of paving with the pea slurry may not be necessary for general use but is a good idea for steps and edges.
I didn't feel the need to add a plasticiser when using SBR.

£16.37 from toolstation
£1 extra if you want the genuine feb stuff
and at over a tenner they deliver one container at a time to your site or home, if there is not a branch near by.
oddly the company is partly owned/had heavy investment from Travis Perkins.
the great thing for me although I am DIY'er (who spends a fortune) I don't have to have an account to get a reasonable discount.

I can get Sika SBR from a couple of places for between £10-£11 for 5ltr. Most builders won't use it though as PVA is about £4 for 5ltr.

B&Q own brand - 8.97 quid vat included
I'm guessing that when you got down to the specifics, it's probably not as good as, say, Ronafix, and we did have some issues with it when using a very wet mortar to bed slate last summer, but once cured, it seems to have done the job.
