Mortar Alternative?

[AJB0009]

I have a few brick steps leading up to the front porch on my house. They are not tied into the brick on the house wall, so I assume there is a bit of different expansion rates.
Is there a product that would work well for this joint? Durable yet a bit flexible.

This QUIKRETE mortar repair caulk in a tube should work for your steps. Available at Home Depot, Lowes and most Ace Hardware stores.

Yes there are some colored cement caulks that would do well. Definitely clean very well and makes sure all loose stuff is gone. Just see what your stores sell, like the Quickcrete stuff

What about a quart of pre-mixed thin-set? I know you said no mortar, but that stuff is easy enough to apply in small areas with something as simple as a plastic putty knife and your finger. No need for a trowel.

Polyurethane caulk is the usual recommendation for masonary joints.

Does that need paint to resist UV? (most polyurethanes die in the sun)

Good point. But for my particular use, no, it would always be in the shade.

This is what I would use.

I asked the chat bot at Quikrete if they had a polyurethane repair caulk. They sent me this (which appears to be UV resistant as well:
