With ref to a previous discussion [15th Aug '03] about Slab-Fix, I have used it to bed 200x100 paving bricks for a 2m x 1m path and found it worked fine. It was my top layer [30mm] over 50mm sand and 100mm h/core, all well tamped. The Slab-Fix layer went off firm in under 12 hrs - and it was laid during the hottest part of this summer. The pavers are good and stable, not a mm of movement. It helps, of course, that my bricks are designed to touch-fit on spacing lugs.
BUT! I used the Slab-Fix to brush into the cracks. Now the bricks are white, instead of nice green/red mottled. They revert to mottled when wet but dry back to white. No change, not the slightest, in 6 months. I'm told brick acid is the answer. Is this right?
In short, Slab-Fix is a perfectly good, cost-effective product for a small job such as my path. By the time you've mixed up the real stuff, your Slab-Fix could be down and you're on with laying bricks.
Brilliant site, by the way.
Note on slab-fix - Slab-fix is ok, ok - but...

Tony didn't think much of it in 2003. ...
"I think this stuff is an expensive bedding and a way of extracting yet more money from non-trade folk who don't realise just how simple and cheap it is to knock-up bedding mix for themselves. I would not buy any more Slab-fix, but would switch to a tried and tested bedding material, namely sharp sand and a dash of cement, such as the 10:1 mix I advocate.
As for the pointing, use a Class II mortar, as described on the main site, or take a look at the pages that deal with the art of pointing for a fully detailed guide to what works and what doesn't."

You're entitled to the work, not the reward.
