Questions on Installing NobleSeal TS
"I’m using Nobleseal TS for shower. I’m comfortable with the modified thinset between membrane and tile, but are you also comfortable with using it between CBU and TS? If so, do you allow it to cure longer than you would for say a non-modified Kerdi thin set?" - Aaron
Aaron signed up to view my private photo albums a couple months back while searching out shower construction blog pages. Today I got this email from him and he asked the question above.
Here is what I wrote back.
"The real secret I think is getting a modified thin-set that has a fine texture.
Something like Ardex X32 or Grani Rapid can be very hard to work with.
I like KeraBond/KeraLastic combo. Laticrete 254. Ardex X5. to name a few choices.
Have you picked your grout colour yet? Do you know what thin-set your are setting the wall tile with?
Keep it all in the same family.
I also like to tape my concrete board seams after it’s installed and also scratch coat and flat trowel the entire wall. Not to build up the thin-set but to seal the tiny pores. This also I find slows the hydration down of the backer board when you are installing NobleSeal TS.
If you are not building a steam shower you could use Noble EXT.
As for dry times I give my installs two days before vacuuming.
Good Luck." - JW
