Do not use liquid colorant. Use Ferrous Oxide powdered pigments, but stay away from Jet Black, blues and greens, and dark red if possible.

Re: Some SBC questions

Would you suggest dyeing it or painting it? The obvious problem with dyeing is color-matching between batches.

Keb.. I used 2 bags on the dome, and I used the dye, matching the color was no problem at all,,, I mixed half a bag at a time in the mixer, added the same amounts of (Quikrete) colorant,, and it all matched perfectly, My only dissapointment is that after a year the color (terra cotta) faded a great deal.. My oven sits right in the sun.. someone else suggested (after the fact) to use iron oxide as it wont fade, I dont have any experience with that so I cant tell you how well that works...

Insert the tile into the SBC.

+1 I've installed accent tile inlays directly into wet stucco and wet concrete slabs before.

Re: Some SBC questions

Adding color to the SBC is best, of course, no maintenance.

The secret is to do it all in one batch, or break it at corners and edges.

Insert the tile into the SBC.

Some questions about Quikrete Surface Bonding Cement (and stucco in general):

I bought the white SBC, assuming it would be easier to dye or paint than the gray. Would you suggest dyeing it or painting it? The obvious problem with dyeing is color-matching between batches. Seems like the obvious problem with paint would be having it wear or chip away, revealing pure white beneath. Thoughts?

I will be placing talavera terracotta tiles onto the vertical wall along with the SBC. Should I place them "into" the fresh SBC, basically using the SBC as the thinset to set the tiles?...or should I do the whole enclosure in stucco first and then mortar the tiles onto the dry stucco surface? (I'm using SBC and stucco interchangeable in this post). That would mean the tiles would stick out from the SBC unless I use some sort of stamp to set a shallow dish into the web SBC. For example, I could use a piece of wood or a tile to press an impression into the SBC, then let the SBC cure and mortar the tiles on after the fact, but like I said, I'm wondering if I should just set the tiles into the stucco while it's wet anyway, everything in one shot...except that I might do the SBC in two coats. SHEESH, I just dunno. What do you think?

Bear in mind, the back surface is hardibacker, if that affects the decision.
