ᐅ Removing Tiles from Oriented Strand Board (OSB)

Hello,

I have another problem now.

The tiles in the hallway and kitchen are glued onto a particle board. Underneath this particle board are the original floorboards.

We want to install new tiles in both rooms. If we level the floor and glue the new tiles on top, the floor height will be too high and the doors will no longer fit. Also, there would be a 3cm (1.2 inches) height difference compared to the other rooms.

I have tried to remove the tiles, but only small corners break off and the particle board also gets damaged.

I would also like to remove the board.

What would you do? Maybe cut it out piece by piece?

Thank you very much for the help.

At the moment, I only have one picture that I took in poor lighting. I had started to cut into the tiles and the board a little bit.

The floorboards will come up, then I plan to install Fermacell boards on the joists, followed by tiles. This way, we can level all the floors and fit the doors properly.

Thanks for the help

Fermacell boards must be fully supported across their entire surface. Therefore, these are not suitable.

You are aware that you first need formwork on your beams, right? This can be made of tongue-and-groove boards, profile boards, or OSB. You can then build the floor structure on top of this.

Best regards

I had the staff at the hardware store show me the Fermacell boards and the leveling screed.

Would that work?

So, the leveling screed on top of the concrete ceiling, and then the dry screed elements on top of that. They would then rest on the joists and the screed.

No, as far as I know, that won’t work. The elements require a non-springy, fully supported surface. Therefore, you need to cover them with appropriate boards or panels.
