So, I attempted to install a ditra-heat membrane in a small bathroom last night and it didn't go as well as I had hoped.
I think either my mix was too dry or I tried to do too much at once, but either way some parts of the sheet seem well bonded, while other parts are not. I think my big mistake is not spending more time ensuring that the mat had 100% coverage. Overall, the mat is stuck to the floor, but there are "bubbles" in places where it's not. The edges, (with a 1 exception) are well bonded.
My question is... what do I do now?
Do I really need to rip it up and start over?
And if so:
- What's the best way to remove the thinset from the floor?
- Can I reuse the mat? Or will I need to order new material?
Tile guy is suppose to be here Monday so if possible I'd like to avoid starting over.
What likely happens if I do nothing?
Would it be a bad idea to just put some screws (with plastic washers) in where it's well bonded? I bought this product for the heating, not the waterproof capabilities, so I'm not concerned about that.
