Floor prep problem.

[afright]

Have got a 30m2 kitchen floor to do in a couple of weeks,and the problem is at the moment the floor is solid oak flooring ,I have removed a small section to see whats underneath and it 12mm ply direct to the joist's ,the customer wants the cheapest way for the prep,I want to overboard with ply and use ditra or would backerboard suffice my concern is the 12mm ply to joist,I have not removed all the oak flooring as the customer wants to do this to keep the cost down and is not prepared to remove it until two days before I start.

If the customer is not prepared to do it properly........then walk away. Do it right or not at all.

 

[radim]

would you guarantee the job if not prepared properly.
.as CJ says - better giv it a miss...

 

[afright]

I am going to prepare the floor but as the customer does not want the oak taken up until two days before, the problem is once the oak flooring has been removed there might be to much bounce in the floor as its only 12mm ply to joist,I have never come across this before always been 18mm ,my question is will the floor be man enough if I overboard with ply and then ditra or go with backboard maybe 12 mm.

 

[Chalker]

Could you glue and screw another layer of 12mm ply the opposite direction to the first layer.

 

[afright]

I could, but would it be just as good if I used 12mm backer board ,the customer wants a good job but on a low budget

 

[radim]

12 mm hardie would do me thinks.

 

[afright]

Cheers I think that would be the answer, I get a good price at Ctd

I reckon that the ply will sag between the joists.
If he's adamant about keeping the 12mm then I would be lifting it & adding a lot of extra noggins to strengthen it up a bit, stick ply back down then overboard with Hardie 500.

Will not know how the floor will behave until the oak is removed at the moment its feels ok but thats with the oak in place.

He wants a proper job but on a cheap budget .. never a good combo

 

[afright]

What the customer is saying is the cheapest method either overboard with ply and ditra or backer as the ditra is roughly same price as backer it cuts out the ply ,there is no way that I would do a cheap job,once the oak is removed then I will decide which way to go and if the floor has deflection and he is not prepared to pay then I will walk,my main concern is the 12mm ply direct to the joist's.

Ply and ditra for me.

what centres are the joists? as Stef, it'll need plenty of dwangs if they want to keep the 12mm. Personally I'd be telling them that the cheapest option would be something like 22mm chipboard overlaid with hardie 250,,,but check those dwangs (noggins)
