tiling over floor grade chipboard

[andy-p]

glad your floor is still down graham!! it may well stay down with no problems, but working as professional fixers we have to use the tried and tested methods and work within the adhesive manufacturers guidelines , you can appreciate that customers wouldnt be too happy with tiles cracking and lifting...

yes fully understand your position as professional tiler.
My tiling was diy so I was lucky to able to take what I judged to be an acceptable risk. The advice from the forum has been very strongly not to use BAL spf on floorgrade chipboard...although for several and different reasons.
This now is purely of academic interest to me - I certainly will let the Forum know how my floor performs over the future.
It may be that the industry is being over cautious and over engineering the job....at extra cost to customers?

best,
graham

Good Post Andy, Sums things up nicely.

I hope it works out for the OP, but i think as you say Andy, if it goes wrong the fixer who laid it gets the call to put it right, I wouldnt want to spend half a working week going round correcting jobs that i'd taken a chance on.

Different story in your own home as you take the chance and the consequence if it fails.

We at Bal invested heavily to produce an adhesive to save overboarding chipboard... therefore saving the end user time and money. We continue to strive to make the adhesives and all other products the best in the market. We asvise people which are the best products for their situation, and have been doing this in the industry since production started in 1966. I find your last comment not only very cynical but also a cheap attempt to absolve yourself after ignoring the advice not only of the manufacturer, but also countless professionals who have attemped to stop you from making a mistake that will enevitably cost you money.....:mad2:

I'd be 100% with you there Gaz - excellent free advice was offered by several of you guys and cynicism seems to be the response. I'm ever grateful for the tech support I receive from BAL and the guarantees that I in turn can pass onto my clients. It'd be very costly if such a floor fails and certainly not worth the risk IMO.

just to give an indication of "potential" problems, I have (hopefully) attached a picture of a floor, tiled earlier this year - not by me I may add, I have just redone the whole thing - that was straight on to chipboard with no other preparation. The floor was less than 6 months old!

I'm replying in the interest of a learning debate on this intiguing topic:

thanks grumpy - your picture is interesting. the main tile in the photo shows cracks which don't extend beyond that tile's perimeter. there are also signs of cracking within another tile; which appear independent to the cracks in the main tile. looks like a localised failure mode on each tile. what do you think caused such localised cracking? was it all down to the chipboard? would usage of bal 2 part superflex (or Ardex?) have prevented this? what did you do to rectify the situation?

it would be useful if any other forum members could also share descriptions of tile failures on chip board.
as i've described earlier, my tiling on green floor grade chip board with bal spf has so far been very successful..... is this really just a lucky one off.... so far.... to be tested by time? and what mechanisms over time may cause cracking?

best,
graham

I did once this was due to the customer not having the funds and being a reguler client, Did explain and what could happen. It was a conservatory, Had the green stuff and was solid, No movement. Used soverign porcel flex then added sbr just to cover myself, The grout was Bal flexi wide joint grout, Have been back a few times for other work and allways look for cracks in the joints, None so far. I done this job about 2 years ago and still sweat that one day I will get a phone call there's a crack in the grout. Never again, You think your helping them out but the first problem and their on your case
