Please confirm this method!
 
Getting ready to lay some tile in a small area. Please take a look over my plan and let me know if I'm overlooking or overthinking anything.

  1. Remove baseboard
  2. Undercut door jambs
  3. Remove old hardwood flooring
  4. Install 1/2" plywood over 1x diagonal planks
    1. Screw through to joists with approved screws
    2. Glue ply to planks with construction adhesive? (not sure if necessary)
  5. Apply bed of modified thinset to ply
  6. Install backerboard into thinset using approved fasteners
    1. Offset seams from ply to backerboard
  7. Tape seams with mesh tape
  8. Mark starting point of tile
  9. Apply thinset to backerboard
    1. Lay heavily over seams (like mud in a drywall joint)?
  10. Set tile in thinset
    1. Spacers between tiles to keep even and square
  11. Apply grout
  12. Wipe grout lines smooth and tiles clean
  13. Apply grout sealer
Does this all sound correct? Please add any details or tips that you can think of. Thanks!

  1. Remove baseboard and casings
  2. Undercut door jambs
  3. Leave old hardwoods, put 3 inch screws into joists and 2 inch in the field every 2 inches or so
  4. Install 1/2" plywood over hardwood
    1. Screw through to joists with approved screws
    2. Glue ply to planks with construction adhesive? (not sure if necessary)
  5. Apply bed of modified thinset to ply
  6. Install backerboard into thinset using approved fasteners

1) Keep a bucket of water and a few rags handy while setting tiles. Clean faces of thinset as you go.

2) Keep a rake tool the same width as your grout joints and rake any excess thinset out of joint as you work. Easier than going back later with a grout saw and especially important if you are using a light color grout.

3) Keep one side of your thinset bucket "clean" and one side "dirty". Use the dirty side to scrape excess off tools, clean side to hang and lean tools against.

4) Tile is more unforgiving than hardwood. Set your cement board screws FLUSH or better! If you nick one with the trowel edge while spreading your thinset, fix it right away.

5) Take proper Silica protection measures when dealing with CBU. Dust control

6) Eye protection is critical especially when using tile nibblers

Hi Nick,

The first 3 are pretty obvious, except you may want to do #3 before #2.

Quote:

Install 1/2" plywood over 1x diagonal planks
Screw through to joists with approved screws
Glue ply to planks with construction adhesive? (not sure if necessary)
4. Be sure it's underlayment grade, not the cheap CDX stuff.

Quote:

Screw through to joists with approved screws
1. Wrong. Fasten into the subfloor, not the joists.

Quote:

Glue ply to planks with construction adhesive? (not sure if necessary)
2. Wrong. Glueing with construction adhesive creates voids.


Quote:

Install backerboard into thinset using approved fasteners
Offset seams from ply to backerboard
6. Yes. Thin set is required under ALL CBU's

Quote:

Tape seams with mesh tape
7. Yes, use the special tape, apply a thin film of thin set now, or wait till setting tiles.

Quote:

9. Not sure what you mean here. Thin set is first applied with the flat side of the trowel, then gauged with the proper notched side of the trowel.

Quote:

Set tile in thinset
Spacers between tiles to keep even and square
10. I would never use spacers for floors. Tiles are not perfect, spacers can force you to run way off.

Feel free to ask additional questions here.

Will Try. Jambs are very tight to flooring, so it may or may not come out.

Ok, so avoid hitting the joists?

I think I'm confused here. I was under the impression that the backer board has tapered edges like that of drywall and need to be filled flat. Maybe I'm wrong... Please elaborate if you could.

Not sure how else I would keep them aligned. Do you basically eye-ball them then?


Thank you both for your help!

No problem, even some pros are confused about this, and some skip this step cuz they don't know or because no one's looking.:censored:

Traditional concrete backers are tapered on the long sides, but not the ends just like wallboard. Many people have trouble with taping and create "speed bumps". So some like to tape while setting the tiles. No me, I like to tape just after the sheets are installed and so it sets a while or longer depending on the size of the job. Either way, make the thin set a little thinner than normal and use a flex 6" putty knife, and keep the build up very thin.

I snap chalk lines to create a grid and set 2 rows at a time. (usually if the tiles are 12-16" +-). Yup, no spacers for me, I eye-ball it. You need to make accurate lines of course. :thumbsup:
