Looking for advice

[Russell brown]

I've got a bathroom to do for a repeat customer in an old house. The first floor is a lime ash sreed over reed, it's out of level and weight is an issue. The client wants the floor tiling, would dirtra or something else be suitable for the floor? As the floor bounces a little. Any recommendations

Some floors really aren't meant to be tiled, this sounds like one to me, plenty of other options out there..cardine, vinyl, laminate etc...

Find a adhesive manufacturer that's makes a ultimate flexible adhesive and ring their tech department.

theres no more bounce than you'd get on a timber floor. Any recommendations for adhesive?

I take you mean a screed over reed, the only reeds I know of are on walls....

yes a screed over reed. Basically the floor joist downstairs are exposed with no void between them and the floor. Reeds were laid over the joists and a lime and ash screed laid on top and a lime plaster underneath between the joists. Hopefully someone can tell me if it's possible.

thanks Russ

My personal view is no, people buy these old property's for there quaint looks then suddenly want to be fixing tiles on floors etc...there maybe a way but not one I've seen.

Morning Russell. .....The most flexible adhesive I've found is bal single part fast flex.

I've no idea what type of floor your talking about, I've never seen one before. ....However 3 excellent experienced tilers are advising not to touch it and you would be well advised to listen to there advice. .

Would it be an option to screw down a new sub-floor, straight into the joists and work off that? It would create a pretty thick floor but could it work?

I've never heard of such a floor but as Andy says I would go with what's been said already.
I would err on the side of caution.

I believe these screeds are meant to breathe... So should it be tiled and should cement based adhesive be used .?

I've been on the phone all day with various technical departments, Webber don't make anything suitable to use straight onto a lime substrate. Mapie are getting back to me, ardex reckon arditex NA will be suitable if primed with p51 primer and dural say the there matting will work as long as there's no more than 5mm deflection in the centre of a 3m straight edge when held against the floor. I haven't got all the information I'm happy with and im still not sure wether it's worth doing, but I'll continue to look into it as a learning curve as I've seen a few of these floors around here.
thanks for everyone's input so far it's all being taken on board.

The trouble also is the strength of lime mortar/substrate, by the sound off it the property is very old so is the lime and it is'nt a strong substrate and starts to break down over years.

Depending on what NHL strength that was used, the standard wall hydrolic lime used 3.5 NHL and goes upto 7.5 NHL which would be almost the tensile strength of concrete which I doubt was used.

I am with earlier posts on this, I would leave well alone.
