Three tiles fell off my wall in my kitchen, and underneath I scraped off the combed white tile adhesive and also another white layer with a knife. It exposed some gypsum and paper like material underneath.
I used three parts water to one part granfix acrylic primer but I read on this page Applying primer - advice please :-) - http://www.tilersforums.com/threads/applying-primer-advice-please.30387/ that it reacts to gypsum.
What does it do to gypsum?
I am panicking, because there is a crawlspace behind the kitchen with timbers and the crawlspace belongs to the buildilng owner as I am leaseholder of a flat.
What will the granfix do to the gypsum. on this page Applying primer - advice please :-) - http://www.tilersforums.com/threads/applying-primer-advice-please.30387/ someone said this "You just need the neat coats on their own when using cement based as it reacts with the gypsum plaster background"
What do they mean by granfix reacting with gypsum background and what can I do to correct the situation please. Here is a picture of the mess I made.
Before the thin coat of granfix dried, I put on another neat coat directly onto the gypsum. I need to know what it will do to the gypsum.
Will I have to have it replastered?
I'm really worried cos i have no money snd the whole kitchen needs doing really.
Will the granfix ruin the gypsum? How does it react, sorry to be in such a panic, but I got really scared when I read the above quote from the thread linked above
Thanks

Qwerty

It will be absolutely fine. If you're that worried about it then just treat all of the exposed accessible timber yourself. A total waste of time in all honesty but if it gives you some reassurance then go ahead. It's relatively inexpensive....... certainly less expensive than a structural engineer!!!

Forget about it, eat a mince pie, drink some mulled wine, burn the turkey and open some presents........ this really does not warrant a second thought.

Go on then, I'll play with you for a bit longer.
If you're a "poor lady" why would you be spending what little money you have on primer, a grout float and the tube of Evostick when a small pot of fix and grout would have done the job? If you're that bothered about rot, dry or otherwise, you'd have done something about the bin bag draped over the windowsill that I assume is to stop water going behind the sink.
By the way, nice work peeling the flower sticker off of the tile. Gives it a real modern look.

Please can you tell me if the bin liner will have caused rot under the tiles on the windowsill. I've been worrying about it for days. I took it off now, it was there to keep windowsill edge dry from splashes.
I would really appreciate it if you could tell me why bin bag would cause rot.
Thank you kindly.

I'm really sorry to go on, it's just that timberwise are dry rot specialists who are accredited and they say on this page "This also occurs where large dimensioned timbers are in direct contact with damp masonry but remain well ventilated in which case the decay only develops within the interior of the member, the outer surface remaining sound." Dry Rot – The Facts from the Dry Rot Experts - https://www.timberwise.co.uk/2008/10/dry-rot-the-facts-from-the-dry-rot-experts/

There's also lots of other sites that say dry rot can develop where moisture is trapped without a chance to dry out, like my wet gypsum with an impervious tile on top, worried about the timber below the gypsum. Treating the outsides of the timber wont help, but thanks for the suggestion, as these sides are ventilated so I know they wont get dry rot but im worried about the side i cannot see.

This is a pretty extreme solution, but then again you do seem to be allowing these 3 tiles to take over your life, so...

Hire an acrow prop, support the joist above wherever the offending bit of timber is, cut out the offending bit of timber and replace with new.

Is any of this at all necessary? No

Thanks for the suggestion but as the timber is in the roof void which does not belong me, I cannot touch it. Kitchen is mine as flat leasehold. I'm on top floor and flat in roof. It's an unusual set up as there is a stud partition wall between the kitchen and the roof void where the timbers are which lie being the gypsum plasterboard.
