Guess I won’t know unless I have an issue but seems to be okay. One problem I ran into as a DIY that maybe a professional would know (but if you’re reading this then you probably aren’t a professional) is that if you use an uncoupling membrane then you should use a mortar specifically for uncoupling membrane. I didnt know that and used regular mortar and it’s taking forever to dry cause it’s between plastic and porcelain tile, two materials that don’t let go of moisture easily. I’m beyond 72h and still have some tiles that are movable. I feel like the manufacturer should have that in their directions somewhere cause I checked before application and it didn’t mention it
