Leveling Floor

pldd4

Hi,

I need to level the floor in my kitchen. At the moment the floor is a mixture of original 1930's small floor tiles and other things.

Is it possible to just pour self leveling compound all over this?

Do you need to pva the floor first?

Anyhelp would be great,

Cheers.

Hi,

You can poor self leveler over this aslong as the tiles are solid underneath.

Firstly apply pva mixed with water read the bottle it will tell you the ration on the back.

Next mix your self leveler do not mix to much, Mix only just enough as your able work with with and you must not put more than a 4mm bed down as it will crack.

I seen a product the other day and you can go as deep as 20mm in one go with this stuff the local tile shop sold it.

Personally i wouldn't use Pva, just make sure there are no loose bits and De-grease the floor.

PVA is wood glue, as soon as the self levelling compund is poured over it, the pva becomes live and sticky again and actually stops the bond between the compound and the floor.

If the floor is dusty and or greasy, then clean it as best you can and if it requires priming use an SBR slurry primer.

Get a good quality product like BAL Multibase or Ardex K15 (or K15B if you need a thick layer of screed) these will be available from tiling ditributors.

Don't use anything from any of the DIY shed, it's utter rubbish.

Thanks Alan,

just to be clear are those products you listed the leveling compound products i should be using? Rather than a big bag of the stuff from wickes?

Yes they are, they are single part levelling compounds to which you just add water, latex screeds are two part compunds and uneccessary for your requirements.

It helps tremendously to have a tall bucket and a drill with a whisk on it to mix these.

The stuff wickes sell really isn't anything like the ones I've advised and it will all be roughly the same price.

Not wanting to confuse matters but you can now get a single part latex levelling compound.Not used it myself but on a recent conversion i was involved with (a pizza shop),the guys laying the flooring asked for it to be used specifically.The floor was made up of differing materials,partly tiled,partly concreted and partly screeded before the leveller was applied.Said stuff was bought from Travis Perkins.

The different materials in that floor sound like my floor, so could be tempted by that "single part latex levelling compund"!

hmmm

I must point out that i am no expert on levelling floors.I have used normal compounds in the past but never latex.Perhaps someone with more experience can advise?
