Floor self levelling compound - TilersForums.com

[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

How big in m2 is your floor ?

3mm?? Wish all floors were as flat as that.

Floor area is 6.5 sq m. Am I worrying unnecessarily about the flatness ?. It seems to have a high ridge down the middle and falls away to the walls.

On the high ridge part of the floor is there a rsj underneath ?

blimey.. 3mm is pretty flat. if it is out by 3mm over a 2m edge it meets SR1 which is the standard that most floor coverings require. My bathroom floor falls by nearly 20mm across the width of the door... its a bu**er going to the loo in the middle of the night...

Especially if you've been on the liquid gold

No RSJ underneath the floor. If I put a straight edge across the floor it has ups and downs but no more than about 3mm. From your reactions it seems that maybe it is flat enough to lay vinyl or interlocking flooring without further preparation.

Ultra level2 goes down 2mm minimum , most adhesive will go up to 12mm some thicker.

Definitely!
