Question:

How do I remove cement board that has been screwed into and bonded with thinset to wooden subfloor?

I am in the process of purchasing a townhome and I am looking to tear up the existing 12 ceramic tile that covers the entire main level... an area close to 600 sq. ft. to make way for laminate flooring. Thinset has been used to bond the tile to the cement backer board, and the backer board has been screwed to the wooden subfloor. There is also some sort of adhesive/mortar bonding the cement board to the wooden subfloor. What tools will I need. Are there any techniques that would make it easier? Would trying to remove the cement board damage the subfloor? If so, would it be acceptable to repair damage with some sort of floor leveling compound?

Answer:

big *** crow bar, thats how i did my kitchen, yep it sucks. you can get a nice one for this in the garden section its made for digging holes but has a nice flat section, for what I dont know but it teats a floor up,
Laminate sucks, but why don't you put it on top of the tile, or on top of the backer board?
