Hi


1: With what should I fill the holes in the floor near the outside
wall, some kind of conrete or loose small stones and then pour self
levelling compound over the top (I read this on the back of the self
levelling compound packet but I am not sure if this will work well).




2: Should I lift the remaing floor tiles as they are so easy to
remove? I am thinking yes but then some messages in the group seem to
state you can lay the compound over the top.

3: Can I put the compound on top of the black adhesive? This seems to
be competely secure to the floor (only the tiles can be removed
easily).

4: Does anyone know if the B&Q Value self levelling compound is any
good. I have also seen a product called Feb Concrete Self levelling
filler is this better?

5: It seems like self levelling compounds I have seen are for concrete
floors, does this mean that it has to be poured directly onto
concrete?



My advice FWIW.

lift all tiles and as much of anything that comes away easily as you can.

Treat the whole floor with a dousing of thinned PVS, execpt the really
loose stuff. Here use full strength PVA. This will bond all the loose
stuff together.

Then use levelling and smoothing compund on everything - don't attempt
(unless you have 2" deep big holes) to use a normal cement screed.

Be aware that self leveling compund isn't self levelling. You need to
float it on if you can. you may need tow goes useing a long sitrit level
to detntify any hollows and fill them. A uniformly flat surface is more
important than a dead level one.


Thanks
