Backer board repair or replace?


Hello all first post here. I am trying to do my first DIY tiling project. I have the first piece of backer board down didn't have to cut it. The 2nd piece however I scored it and when I went to snap it it just ripped randomly down the line. Pictures as shown. Would I be able to repair this with fiber tape and thin set? or should I buy a new board and try again? Where its torn after laid down would be about center of the room.

For $12 should you even consider wasting tile and quality of job?

Some might. I would throw it away, call it experience and do it right.

Lazy, did you use a knife designed for cement board? (not a standard utility knife)

You'll get cleaner and easier to make cuts with something like this:

When snapping Hardibacker---use the scorer pictured above---then place your knee on top of the score and pull UP---just the opposite of cutting drywall---

Be sure to set the rock into thinset before nailing---(like a giant tile)

I hear you. I am going through the exact same thing right now. I got the first layer of the sub nailed in place and hope to get the 23/32 layer nailed in place on Monday. Then I will be ready for the hardie.

I bought a backer board score man it made it so much easier. I am about ready to begin laying down the tile only I noticed my floor in one corner is uneven It's pretty bad. Should I use cement leveler or can I float it with thin set? Good luck Colbyt Hope your project goes well. I know I'm learning alot.

Can't tell where that slope is from the picture. A quality tile job needs flat more than absolute level. Of course if that slope sends water in the wrong direction it could cause future problems.

That is out a full bubble if I am seeing it right. Where is it low?
