How To Remove Hardie Board From Subfloor

Here is an thought to consider. If the tile comes off the cement lath fairly easy, you could leave the cement board, scrape off the thinset and lay your foam and laminate over the cement board. Just a thought depending on the overall thickness you need to accomplish.

If information technology was installed correctly, the cement between cementboard and wood volition exist thinset and it will break off the wood fairly easily - it'south put there to fill the space well, not to actually bond it especially. If information technology was glued downwards with construction adhesive you might be in for a more miserable time. Safety spectacles, gloves, and a sledgehammer to go started. Y'all'll probably accept to break the lath around the screws and remove them with locking pliers - the screwheads volition be full of thinset and it would be tedious to get them to the point y'all tin utilise a screwdriver on them once more. Beware of screws that suspension off - they can be abrupt if you don't immediately remove the stub from the flooring.
Y'all can try driving a wide (4" or so) flat chisel nether the edge to pop sections off, merely directly sledgehammering will probably be faster.

I have the same trouble and need to remove the tile, durock / cement lath as well as the subfloor due to water leaks and mold. Nothing is easy near this job, but scoring the floor with a skill saw cement blade has certainly helped past making the job a lilliputian more than manageable. Open windows, block all vents and mask required! Dorsum to work. . .

It'due south best equally a ii person job with i person busting and one removing ideally. Just did one today.
How to to do it? An electrical chipping hammer to take off the tile offset. Then a 2 lb hammer to knock some holes, so just pull off the durock in fairly big pieces, like three x 3. Don't kill yourself,.....have 2 people carry information technology out.

I thought this was a shower demo,....sorry. On a flooring I'd endeavor to leave the durock if possible. Broad blade chipping hammer and / or maybe rent a car. That's a lot of tile to use a chipping hammer on.

I'd too consider going with a wood look tile. Information technology would be easier since laminate snap together flooring requires a very flat surface or information technology volition not work. With tile you have the thinset every bit a buffer. I personally would non do laminate in that state of affairs due to the tile unless I could go on top of the tile.

Thanks, I'k pretty certain that it is just the thinset in between the cement board and subfloor. It is skilful to know that it should come up off with not too much problem. Your saying its all-time to arroyo it by breaking the board with the sledge? Would it exist possible to use a prybar to take it up faster?

You could certainly try a heavy crowbar/ripping bar on it, and see which is more than effective. A thin prybar (wonderbar) will probably get bent. Depending how the tile comes off, @shirlock homes has a good point - cement board, if yous can become the thinset off (a silicon carbide rubbing cake may be handy for the terminal bits) is a perfectly good base for laminate. That might brand the wide chisel for popping tile off make more sense.

Thank you for the input, definitely something to recall about - leaving the cement lath and putting the laminate on the cement lath. How hard do you guys think it would be to remove the thinset from the cement board?
