tiling on chipboard

I notice that my post
tiling over floor grade chipboard

continues to get viewed, and now has had 17777 views. It seems tiling over chipboard is a recurring situation. The post was locked over a year ago, but if it could be now re-opened, then I'll post an update on the status of the tiling.

IMO I think it like driving without seat belts I never had a accident so I think it's fine or Like the drink driving of tiling :ban:Imo

Re-doing one now that failed after 6 months:

Chipboard and osb are cheap so will be popular floor construction materials. Tiles are popular so you will get asked to tile on it.

Dont.....simple as that really

Sharpfamily - I personally don't see how it would benefit the forum by re-opening the thread.
Your floor has either failed or is fine - neither would suprise me.
The fact that if your floor has failed wouldn't surprise me is the whole point.

There are 1000's of floors tiled directly onto chipboard that are fine and stable and even if only 1 in 20 fail that's still 100s of floors that have failed that needn't have if done correctly. I've ripped up loads of failed floors on chipboard and re-done the job correctly - at great inconvenience and expense to the customer. No Pro-tiler on here would advocate tiling straight onto chipboard and this forum is used by tradesmen and the general public alike and is all about giving the correct advice. Yes you took a gamble and it payed off but you don't do this for a living, and I wouldn't make much of a living if I did what you suggest as I would be going back to several jobs a year and ripping out and re-doing at my expense.

possibly time to move on? lol

think macten has hit the nail on the head, and the 17777 peeps that have veiwed the thread hopefully realise no pro tiler would advocate tiling to chipboard, i can see no point in reopening the thread and going round in circles again..

well said Nick

in the bottom photo it does look like the problem was with poor quality adhesive - it doesn't appear to have stuck to the tiles,
Was the chip board floor grade T&G (green)? The grouting in the other picture doesn't look very good.
Is chipboard getting unfairly blamed for poor workmanship and other factors. 6 months to failure is very quick.

macten suggests 1 in 20 tiled chipboard floors may fail - this raises the question of why 19 in 20 are successful?

Lots of hackers here in UK. Laying tiles on top of plywood is totally wrong. Since in London I've been asked several times to just tile on top of ply, green board, wire mash. Couldn't do it . How in the H..L a tile guy does that , it's beyond my knowledge. Unbelievable

perhaps you could commission a study for us and find out?

your still looking at it from a DIY point of veiw, why would we take the risk if even 1 in 20 jobs fail, who wants to build a reputation on luck...

if i remember your an engineer, its like you recommending i fix two pieces of metal together with super glue, it might work for a bit, but why take the risk when you can just weld it ?

I think both posts should be deleted I think itS a wind up I can't see an educated engineer behaving like this

 

[sharpfamily]

Why?
Well, usage say of backer boards such as Marmox etc would have increased the cost of the floor by £800 - not including the material costs for fixing, and the extra installation time. I don't know professional tilers day rates but I guess the overall extra cost would have been then have been much higher......double....£1600?? And there's the problem of extra height of the tile flooring. For bathrooms I have used insulating tile backer boards (Warmup) on existing chipboard floors, as the boards also significantly improve the performance of electric under floor heating, as well as being waterproof.

As regards welding metal pieces together - note that aeroplanes don't have any welding in their structures, but are fixed together using pop rivets, nuts and bolts,..... and glue!

As regards commissioning a study on why seemingly 19 out of 20 tiled chipboard floors are successful...........this could be it, but needs more considered responses than pjc's.

By the way, I had a look at the adjacent thread on problem of primer peeling on anhydrate screed...............overboard with green chipboard?! only joking!
