Kitchen floor is like the moon surface

Coveredinbees!!!!

My kitchen floor needs to be leveled so I can tile it but it currently resembles the moon surface as I had to remove the old quarry tiles. I went in to wickes and they have 2 types of leveling one cost around £8 for 25Kg and the other is a latex at £14 for 25KG. The question is which should I use as I need to have it quite thick in places to fill in some of the craters. I want to get on with the job asap as we're having to go to my fathering laws to eat and the novelty is wearing off.

There is a maximum thickness that can be layed in one coat so you will have to use several ..have a look on the instruction panel on the bag to see what this thickness is..

It sounds as if there are a lot of raised pieces of adhesive or grout where gaps were between the old tiles. I think you need to try to scrape or chisel this off to level things off. Once this is done you may not need levelling compound at all.

i had a wooden floor in my kitchen. not a level bit in sight!
decided against the leveling compound and used 8x4 hardboard sheets instead.
dirt cheap.
used the correct flexible tile adhesive on top. no problems at all.

What you need to do is mix a small amount and top up the deep holes and let it set. Then mix some more and cover over everything.

I always paint the floor with pva first too, this has 2 effects it makes sure it stays stuck, and it stops the original floor sucking the water out of the SLC which means it flows for longer giving itself adequate time to level out.

Mix it as thick as tomatoe soup tip it on the floor and use a sweeping brush to make sure everywhere is covered then just let it do its stuff.

I think the latex one is for on floorboards where you need some flexability.

The reason it's bumpy is because to old quarry tiles were laid on a sand/cement mix some of it was soft and came up easily and some of it was rock hard. also part of the floor was an outside toilet which had to have the section where the old wall was bought up to the same level and the old loo floor had to be lowered. once the big bumps are out can the whole floor be done in one hit as it's around 12 Sq meters. The plaster gave me some unibond and said to mix that 5 to 1 and apply that before the leveler.

Yes it can be done in one hit.
And the unibond is PVA... what I was on about up there ^
