Hi all,

I've laid some Arditex NA over the kitchen floor area (not under cabinets. The area is 4.5m x 1.8m.

The top third of the room is totally level. The remainder of the room has a slope, left to right with a max difference of 7mm in an isolated area and 5mm for average. (1mm-7mm left to right). This area of the floor is flat, bar 2 high spots of 1-2mm (not level, if that makes sense). There are no dips / hollows.

Around the entrance, there is an area that extends 200mm from door which is 5mm lower than the rest of the room. There was a sneaky wee hole which I'd missed before pouring and its sucked some the SLC down, despite me trying to plug it.

I should say that I have only tomorrow to complete this and get the tiles down, all day, but only one day to tile and grout. I see there are a number things that may be suggested, but no 3 would be my preference!

1. Grind down the left side, lay more SLC at the entrance. (I do have a grinding disc which was used on the original concrete)
2. Grind down the left, make up the difference at the entrance with tile adhesive. I've got Rapid Flex Fibre plus which can be laid unto 12mm in isolated areas.
3. Take the slope on the chin and make ups the low area with adhesive.
4. Get to CTD first thing, grab 2 bags of NA and attempt to feather in the floor to match the high spots...risky if the feathering in doesn't work and I end up creating ridges etc.

I'd really appreciate if anyone could lend me some advice as to what you guys would do with such limited time? Disappointed as it appears I just wasn't confident enough spreading the compound around ,thinking it would 'self level'.

Worth noting the tiles are 200x200 porcelain.

Look forward to you responses ,pretty please!

Best regards

A rubbish tiler.

I had a similar problem in my kitchen, made up the difference with tile adhesive. Straight edge and a spirit level to keep it in check as I worked.
Came out looking good but it was a faff.

Grinding is probably a last resort, messy, and you'll be forever fine tuning it.
