What is red guard and how long has it been used?
I tiled our bathrooms showers and tub with travertine about 11 years ago.
For the showers I used a rubber liner on the floor and up about 16" on the walls. Then used hardibacker on the walls. Used a mesh tape in a bed of mastic for the joints and mastic over all the screws.
Did I do it wrong?
The tile was put up with mastic and I forget what size notched trowel.
Been going strong for 11 years now and nothing loose or fell off.
Eta. I think it was a V notched trowel, 1/8 or 3/16. ?

I first saw it being used about 14? years ago.
You should be fine. You used Hardibacker that does not wick moisture like Durarock can. Did you let the mastic dry on the joints and screws before putting the tile up?
For future reference use thin set to attach the tiles to the walls, Especially large heavy tile like travertine. Once mixed it starts drying, nothing really stops it. Mastic stops setting up if you cut it off from air, with large tiles its possible to have spots that don't set properly.
This is just my opinion. I was a plumber, not a tile guy. I've tiled a few bathrooms for myself and family. I'm way to slow at doing tile to ever think about doing it for money.
