Bubbles in Kerdi flange

Hello again everyone, I appreciate the advice I got in my last post.



We are plagued by bubbles again unfortunately. We set our drain and flange seal today and there appear to be a few areas with air pockets. We finished about 5 hours ago, so I am not sure if its possible that everything is still curing/drying. We used allset thinset and it was a good consistency, pretty fluid but held the trowel lines. The areas I'm seeing we are able to what seems like push the air around with our fingers. We checked for coverage while installing and it looked well covered.



So my question is now, how do we fix this? Silce and patch? Wait for it to all set up and see where we are? I pray that we do not have to tear all of this out. I have added some photos of the main problem areas.



Thank you for any advice, I appreciate it

No I think you're fine just fixing the problem. 4x4 is more forgiving.


I'm not sure in what context people are saying not to use hydroban, other than a warranty issue.

But ..... Coach already has videos discussing the schluter "warranty". Or lack thereof.

I opt for the hydroban over the warranty on every shower.
