Hi
I have just laid yellow tongue in my kitchen dining area, however because i needed to get it down quick, there is a bit of bounce, in a few of the boards. I would say about 2-4mm.
I was planning to either lay a floating floor, or tiling (laying 6mm fibro cement beforehand)
The area would be very dry
Is this going to be a problem?
what about polished concrete what would i need to do then?
What has caused the "bounce" you speak of? That might be best addressed before you lay anything over the top.
not 100% sure, i would say it is because the bearers where a bit far apart i think they were about 100m further apart than required for the yellow tongue
Yellow tongue is supposed to be on 450 centres. If you've overrun that appreciably, then the only things which will stiffen it are adding more members underneath, fixing another layer onto the existing, or brooming it with a solution of Viagra.
Could you go with a full 18mm or so tile underlay, glued and screwed to the yellow tongue - or is that going to mess up your floor levels massively?
Also watch your ceiling height if the floor's being raised; a kitchen can be under 2400 but other rooms generally can't.
celing height isnt a problem, 18mm + tile would probably raise the floor about 20mm above the lounge room floor, this would be at the doorway leading to the halllway
would this be a problem? to much of a trip hazard?
Generally you can put a one-piece sill of some sort to edge off the new work; slate (costly) or hardwood both work decently - just round over the outside upper corner with a 10mm radius or so and make its top face flush to the new surface. Make the breadth of this sill equal to the jamb - about 110mm in a BV, often around 140 in double brick.
Check your tile thickness; I'd suggest tiles for a trafficable floor are going to be pretty chunky. How hard would it be to rip up the yellow tongue and replace with particleboard rated for 600 centres?
Ceiling height particularly applies if you're building new work, or going to be selling while any part of it is still under warranty. Any buyer's advocate (eg, building inspector) worth their salt will pull you up on a non complying measurement in these cases.

thank for all the help, have a few months to decide, so far here is what i am thinking
- remove yellow tongue and replace with boards designed for 600 spacing
- Add a layer of 19mm cement sheeting
- add a layer of 6mm cement sheeting and see what happens ( i am 120Kgs and may be being trying the boards a bit more than normal use)
