In theory yes - but I would urge you to mix up a small amount (250g perhaps) with a proportional amount of water (50ml) and see if you think it will self-level.

Then either proceed if you are happy with it - or try adding quite a lot more water (record how much) and see at what point it will actually "do what is says on the tin".

Adding 5 litres of water to a 25Kg sack = a thick sticky mass which will no more smooth your floor than a sackful of cobbles.

Question
Can this self leveling be used straight on top of a plastic damp proof membrane?
If so, would i need to glue the membrane to the floor first and perhaps add a layer of glue on top before i lay the self levelling compound?

It this wouldn't work, how would i come across laying the both of them, what else would i need?

Not completely certain of what you are doing but if you are leveling a concrete floor seal floor with pva/water allow to dry then use self levelling compound.When compound sets place moisture barrier on top.Then underlay then carpet/laminate.The self leveller needs to stick to the base properly otherwise it will crack and break up.

No we do not recommend doing this. We suggest lifting the laminate flooring up and then laying this product down.

For further advice please call our Customer Service Team on 0870 608 9001.

Question
Is a base layer recommended?
Applying to an old concrete kitchen floor, is it a good idea to use a waterproof sealant before applying the levelling compound? If so, what would you recommend?

When using this product the surface will need to be at least semi porous.

We would advise against using this levelling compound directly over waterproofed concrete as this will not adhere properly.

This product can be used at a maximum depth of 5mm, at this depth a 25kg bag would cover 3m2. At 3mm thick the 25kg bag would cover 5m2.

Question
How long will I have to let latex dry on a concrete floor before I put my laminate floor down.
I have got an uneven concrete floor in the dinning room, my builder told me that I'll need to put latex down to level it before putting DPM layer and then laminate floor. He mentioned that laminate floor can be put down in 24 hrs after latexing the floor.
Is that true ?

I would probably give it a bit longer than 48 hours.... really depends on at what depth.

I would personally put the DPM down first (under the latex)
