💡 How does an uncoupling membrane actually prevent tile lippage?

It creates tiny vertical channels that let the substrate move independently from your ceramic finish. This handy system takes the stress off rigid joints before they turn into ugly cracks.
- Channel gaps absorb structural shifts and deaden impact noise
- Self leveling adhesive surfaces skip messy priming steps before laying
- Moisture proof barriers keep wood framing dry during winter thaw cycles
