I think you've already thought way too much about 3 tiles. The amount of water held by 3 ceramic tiles will not start rotting the wood behind it. If you can see the other 3 sides of the wood (although I cannot imagine how this is possible) then there must be plenty of opportunity for the wood to dry out naturally.
Hi I will try to explain as best as possible, I am not a troll honest. I am female and didn't know what I was doing and should have come here before I even attempted the job.
The set up in my kitchen is hard to describe.
I own a top floor flat in the roof and there is a crawl space behind the kitchen and bathroom where the velux windows are, this is where the timbers are.
When I say i can see 3 other sides of the timber I mean that the fourth side touches the gypsum, which I soaked by wrongly applying watered down primer, soaking the gypsum.
Here is a picture of what is on the other side, I have put a red arrow pointing to the side of the timber I cannot see, that I am worried is rottting due to soaked gypsum plasterboard not having chance to dry, as I stuck the tiles on top of soaked bare gypsum plasterboard. I hope that clarifies things but will be happy to give you any more information.
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.

Thank you pdc for your post.
I promise I am not a troll, I am really worried that I have rotted the timbers in the picture with wet gypsum by sealing tiles on top with evo stick and trapping wet gypsum behind the timbers shown in pic above with the red arrow pointing towards the side of the timber that I am worried is vulnerable to dry rot as it is not exposed to air or light.
I say I am poor in that I need my whole kitchen redoing. Blown plaster underneath the tiling, in this picture, which I have put a red X on needs redoing, so tiles really need redoing, as do tiles on the windowsill. The whole kitchen needs gutting, which is what I cannot afford. Sticking the three tiles back was a temporary job.
I made some errors by using the primer before consulting anyone.
I rang granfix who made the primer and the man said I can only use cement based adhesive now that I have primed it. He said the tubbed adhesive is not cement based and that i would have to use powdered based adhesive, but I didnt want the hassle of buying a big sack and the mixing of it.
I confess I didnt really know what I was doing. I thought buying evo stick to stick the tiles down, and using the tubbed grout just to fill in the spaces between the tiles would be easier.
The top layer of paper from the pink gypsum plasterboard came off when I scraped the old grout off before soaking the bare pink gypsum plasterboard with watered down primer.
There are two reasons why I am worried about rot in the timber in the picture above of the space behind the kitchen.
1)Soaking the bare pink gypsum plasterboard, not giving it chance to dry before sticking the tiles down with evo stick.
2)
The plastic bin liner. I put that bin liner there because there are loads of cracks in the grout on the windowsill and edge where the taps are, as they are chipped. Below the tiles is pink gypsum plasterboard.
I thought the waterproof bin liner would protect the tiles from getting more splashed and water soaking through the broken and cracked grout, risking perishing the gypsum plasterboard underneath the tiles, and rotting the timber beneath the gypsum plasterboard, as the timber is already waterstained. (see other picture below)
Please can you tell me if I have made things worse, rot-wise by having the bin liner on the tiles for all these months (now taken off), and if the bin liner has put the timber beneath the gypsum plasterboard more at risk of rot, how has it done this? as I really need educating, and am worried the bin bag has made the timber beneath the gypsum plasterboard under the tiles more vulnerable to rot, as it is already waterstained there too, as per picture below. The red arrow indicates a waterstain where there is chipped tile edge, which is why I put a bin liner there to protect it from splashes, the blue arrow is the timber the gypsum plasterboard, underneath the tiles behind the taps. There are more waterstains on the timber in the crawlspace beneath the windowsill, under the pink gypsum plasterboard, beneath the windowsill tiles as the grout in these tiles is broken or missing
I am desperate to know, have I made things worse, rot wise, by using the bin liner to protect the tiles behind the taps, and if so, please could you tell how the bin liner could contribute to any potential dry or wet rot in the timber, as the timber does not belong to me, it belongs to the building owner, as the flat is leasehold rather than freehold.
Sorry to sound worried and I hope I am not seen as a troll, I just thought i would tackle the job myself, should have come here for help first.
I have now taken away the bag and put a wooden small chopping board behind the taps to protect the cracked tiles from splashes, as the chipped area keeps getting splashed which caused the waterstain in the pic with the red and blue arrow on, taken before i put the bin liner there. I thought I was protecting the wood with the bin liner. Could it have caused condensation? Is that why it may aggrevate any rot in the timber in the crawlspace beneath the gypsum plasterboard under the tiles?
thank you
