advice needed : SLC kitchen floor with new kitchen just fitted

[sjw450]

Hi guys,
need some advice on leveling a kitchen floor.
job is 8 square metre floor to tile with 600 / 300 brick bond onto original concrete base,
the concrete floor is a mess, it had 2 levels of tiles originally down which the joiners removed and theres big chunks missing and holes all over it, it looks like the olympic bmx track!
if the joiners had levelled room when it was empty it would have made their lives easier as well as mine as they were complaining about a 30mm drop across floor. However they just left it and fitted new kitchen and said tiler will sort it lol
ive only ever used slc in empty areas with walls as a perimeter for it to set against, im needing a bit of advice how to do it as theres a brand new kitchen just been fitted, the kitchen units run all the way around the room so its basically the middle of room that needs screeded plus the 2 parts for washing machine and dishwasher which go right back to the wall
obvioulsy i cant screed up to plinths they need to come off so any ideas best way to do it?
also the slc will need to be pretty thick at some parts approx 20mm max, any recomended brands, im going to ctd later this afternoon
thanks for any help guys its just something ive never done
cheers
steve

Remove the plinths and get some hardboard, ply, backerboard strips to form a barrier to stop the flow of the leveller going under the units. Pour SLC and job done, I use Ultra level One or, Mapei renovation screed or Weber floor flex.

Take some before and after shots for us We love pictures.

Abnother alternative to the backerboard strips is using Instastick expanding foam, it dries in no time and will fill any holes that the leveller like to run down. It's low expansion, so it's easy to control.
It may pay to put some marmox boarding down to make up the levels, as you will use loads of SLC. Then as Sirarmic says level. Mapei Renovation screed is an amazing SLC. If you really want to make a plush job buy a spiked roller from trade tiler, this pops any bubbles and smooths out the floor to a lovely finish.

And make sure the back door will open once you've SLC'd and tiled before you start. For damming, I use offcuts of marmox etc.

I'm wondering why your kitchen fitter didn't rectify or get it rectified once they noticed the issue. I can only imagine what the kickboards look like. Can we have a picture please?

I think the "kitchen fitter" should of done his job properly personally.

 

[Ceramico tiling]

the tiler should be able to start from the highest point and just level it with the tiles. the leveling compound will just save on tile adhesive. I wouldnt bother if I was calling a tiler

To 30mm?

To 30mm?

yes. I have never had a problem building up with adhesives.I build up low areas with adhesive (about half their depth) and then tile once it dries.If anyone has actual experience to the contrary I will deffo change my methods.???

I have experience to the contrary as do all the other tilers I know. Your method is expensive, laborious & could lead to less than 100% coverage

It would also void any warranty from the manufacturer for exceeding the maximum bed depth. Unless you use PTB but even then i'd say 30mm would probably exceed that too.

Without looking in my piles of literature I think it would indeed. Good shout mate
