Trowel sizes

I know this has probably been discussed a 1000 times but I was wondering if someone could verify the correct trowel sizes

1. For putting 1/4 hardie board down over 3/4" subfloor With modified thinset.
2. 12"x12" natural stone on floors ( mainly slate or travertine)
3. 12" x 12" ceramic or porcelain on floors
4. 16x16" on floors.

Thank you and sorry to repost this

Trowel sizes

Hi Tweed,

There is no absolute answer to some of your questions since it may depend on other related factors. However......

1. 1/4x1/4x1/4 is the best choice. Making sure the thin set is a bit thinner than normal.

2. If the floor is to specs the same 1/4" trowel as above, plus back-butter. Keep a 1/4x3/8x1/4 handy. Do you have a double wood subfloor under the Hardie? Are the joists spec'd for natural stone? Most are not unless up-graded.

3. These need 1/4x3/8x1/4 trowel.

4. Large tiles required medium bed thin set mortars along with large notched trowel 16", go with 1/2x1/2 or 1/4x1/2x1/4. Probably need to butter too.
