Floor levelling

dander

I've got a concrete floor that I want to lay ceramic tiles on. It's about 9m2 in total. In general it is fairly flat, but there are two distinct levels within the room - there's an l-shaped chunk of about 3m2 which is about 2-3mm higher than the rest. So I need to bring the other 6m2 up a few mm.

Is floor levelling compound the best way to approach levelling an area like this? If so, I'd appreciate some advice about how to go about using it in this kind of space, should I work in 1m2 chunks or something like that?

Na, do the whole 3 square in one go - Don't pour too much down at once ( you might put too much down) pour a little bit and spread it with a trowel - this way you can "guage" how much you need to be putting down) I answered someone elses thread that said why use a trowel quote "surely its self levelling" Yes it is self levelling, however by using a trowel you are moving it to where you want it. By doing this you will help it get somewhere close. The compound will then continue to "self level" to give you a nice level surface. If you have any small imperfections when it is set ie a small ridge where it meets the higher floor level use a small "smoothing stone" (Looks a bit like a pumice stone) and smooth the ridges away - really easy.

Watch this video below. Aprt from the fact the old guy is a messy git and he is using what apears to be some sort of squeegy mop head instead of a trowel you will get the jist and see the product in action.... Doe'st matter what brand you use as long as its call self leveling compound the results will be the same.

Cool, I quite liked the look of his squeegee thing for having the extra reach, but I guess that's why you say only pour a bit at at time - so you can reach far enough to trowel it.

Spiked roller is what we use to get level and silky smooth

Gets rid of any air bubbles

Try CTD and get some Mapei trade plan slc for around £15 per bag

Cheap spiked roller £10

Cheap float to spread floor £10

Which will give the better job??

SLC will not level on its own if poured, It needs to be spread a little

We have done floors from 1sqm to 80sqm from 3mm to 60mm in one hit

what is ctd?

To be honest, I'll probably either just fish in the cupboard for some spreading device and if I have nothing suitable, see what they've got in Poundland :T

B&Q self levelling seems to be cheaper than Wickes, but has a load of horrible reviews, so I might just get the Wickes stuff.

The Mapei stuff on concrete does not require primer, Just dampen surface down

I have used the SikaFlex that B&Q sell when i could not get to CTD, Set like crazy paving and did not bond to existing surface

Stuff you need is Latexplan Trade
