unlevel edwardian quarry stone floor with damp

[MangoPete]

HI folks
I did have three layers of vinyl on the kitchen floor an insurance flooding means its all come up. and the tiles are bare. I want to seal them and put vinyl down again
Carpet right said put down a scee then lay the vinyl on that or use hardboard. I said the damp will come through
Allied said it needs sreeing then marine ply then vinyl. but it is too expensive. Can't I just put a thick dpc down then lay marine ply onit then the vinyl. Or am I being too simplistic?
I would love your advice. Otherwise will be back to putting down three layers of vinyl. DOH
Thanks
Peter

[MangoPete]

If it is permanent dampnes then only specialists could make a proper job. If it is occassional damp then possiblyensuring all the spaces are fil;led in using a floor levelling compound then a builders type pvc laid down before boarding, then vinyl. Is it a small or large area,does the damp go up the walls

Thnx hard @it
the vinyl seems to sweat onderneath if layed on the tiles.
the area is about 3 sq metres but three walls have units around them so there is no vinyl under there. There is no rising damp in the walls

You say damp will come through? is it damp? I have a concrete screed under tiles with vinyl on top. When renovating the kitchen we lifted the flooring down to the screed and in places the floor felt "damp". It was infact condensation. The screed floor was very cold, and once the tile was lifted the warm air in the kitchen created the condensation on the colder screed floor. After an hour or so it was dry again.

You could lay the builders pvc and then put a layer of polystyrene insulation preferably 50mm, but this may be too much, so any thickness to suit even 22mm. Then put your boarding on top but do not fix through to the floor. If you make boards and vinyl a good fit then the little expansion should not touble it and the floor could be semi floating, (you'll never notice).

Hi Pete,

i to have had the same sort of problem as yourself.

So a friend of mine told me to buy some paint on damp proof from B&Q, put on 2 coat's let it dry then mix some selfleveller pour it over the top and leave to dry.It's been fine every since.

marine ply wood is 20 dollars a sheet. why are you putting vinyl over tile? just use a tile sealer and leave the tile down .the sealer will make it waterproof.

[Hard@it]

Please let us know how you got on.

Dear Hard@it
Ok well after deliberation I have decided to use this

and then put a vinyl on top.
I havew secured the three woblly tiles by raking out the grout around the sides and using no nail mastic. This allows for a bit of flexing witout crumbling . There was a scree floor over the tiles but these wobbly ones broke it up above them.
I hope this works the membrans seems good and th whole floor can be done in a day.

Sounds good to me, never heard of it. Was it expensive per sq. metre, does it just lie on the floor like an underlay ?
