underlayment


my kitchen floor that I'm going to tile (sometime:-) has a 1/4" underlayment on top of the 3/4 subfloor. this underlayment was added by the guys who put the floor down 20 yrs. ago (Manninton gold)
should the underlayment come off (it's glued down well) before "backer board" goes on? it would be lots easier to leave!

tnx,

Technically the tile installation industry doesn't want that 1/4" product there and it may blister severely when you apply the thinset needed for your tile backer.

But, if it is glued that well it may be a huge bag of worms to remove it.

Your call - you're there.

Yes, technically you would remove it, but I wouldn't unless it's damaged. 90% of the linoleum floors we upgrade to tile have this same situation, seems most people don't like the idea of replacing sections of subfloor that are shredded by pulling up glue needlessly-imagine that! Do a careful inspection putting weight on different areas and listen for squeaks. Most of the time it will be just fine as long as the glue (PL400 or similar) was put on nice and thick. Use a latex-modified mortar to put down the backerboard with coated screws.

Just be sure it is really glued. It should have been stapled. Many times, the adhesive used to install the vinyl will obscure the staple heads, since 1/4" staples are what should be used. Gluing is not recommended because it is hard to keep from having a void in the glue and that can make an uneven floor and cause a popping sound. A void can also cause failure of the ceramic installed over it.
