uneven floor in old flat - TilersForums.co.uk | Tile Forums

Hullo Folks - Got a job to quote on and florr is running all over the place.In the middle it runs out 18mm over a 600mm level and collapses towards the far corner.Customer has asked me to tile and have my doubts it can be levelled.It is old tongue and groove floorboards.Customer is willing to try anything to level out and tile.Is the best thing to use cement backer board on floor and try and level on a thick bed of adhesive?Willing to kick it into touch as not confident of good results.Any ideas??

Spider Sense was on fire with this one - just needed someone to back up my hunch.Thanks Lads-just think too risky for rep.

Yeah, sounds like a right torrid job, I'd stay well clear too.

Floor needs to come up, see what state joists are in and then relaying level BEFORE considering tiling. Otherwise everyone is giving sound advice, walk away because when it fails the tiler gets the blame.

Hullo lads - Surprise surprise - joiners have been in and brand new floor has been laid.Replaced with 18mm brazilian ply and level pretty good.Can i tile direct now or do i need to fix another layer to tile onto.Need some advice !!

18mm isn't enough to be honest. Put another 12mm ply down , screwed at every 6", then your off. I'd use Ardex timbersystem.

excuse the ignorance what is ardex timbersystem fred?

Fred · 04-10-2007

Ardex timbersystem is a specially formulated powder adhesive by Ardex, made solely for wooden floors. It is nearly as good as two-part adhesives. It sticks to wood like glue, and to your trowel as it goes, so you have to be very clean. It comes in grey and white and is rapid setting. It comes in 20kg bags, slightly expensive, but good gear. I use it alot, and recommend it.

Sorry, forgot to say, highly flexible.
