Floor self levelling compound

[Casper]

Hi
My bathroom floor is not particularly level running out of true approximately 3mm. As most flooring covering manufacturers stress the importance of having a level floor I think that I need to use self levelling compound to achieve this. Can someone please recommend a brand to use as there are many out there but with wide ranging prices. I am not looking for a rapid set mix but one that gives a longish working time and ideally would like one that can be spread down to a feather edge as I do not want to increase the floor height anymore than necessary.
I have used BAL wall tile adhesive and see that they market level max but is 2-3 times more expensive than the cheaper brands. I only want to do it once so don't want to go cheap and regret it but also don't want to be ripped off. There are also some patches of vinyl tile adhesive left on the floor which is impossible to remove.

Thanks

Yes Andy sand and cement screed, screws with raw plugs and it's a piece of cake.

if you were thinking of laying vinyl I'd personally go for a 2 part like Ardex NA. You get a much smoother finish than a water based fibre re enforced one

If you are 'sticking' down any soft floor covering then you have to buff or sand the floor first but in this case it's cushion floor which is just loose layed so it should be ok.

I had an interesting chat with Setcrete this morning, so I thought I'd throw it in the mix. Although there are a lot of self levelling compounds on the market, the setcrete guy said that the only true SLC, is water, so all the marketed problems need a little help, hence put the screws and rawlplugs to the level you want, and help move the product with a trowel; just don't overwork it, or powder will rise to the top, and give you laitance problems. The SLCs that say you need a covering on them, will take a heavy weight, but not movement, so if you drag something across the room, you'll easily scratch the surface.
