Placing end grain against brick wall?

[Kalle Olsson2]

How do I best facilitate upcoming paintings?
Painting next to the brick is difficult and I can't reach the end grain, which is the most sensitive part. Should I install a cover cap to protect against water? Or an upright strip next to the brick that can be removed when painting?

I would be content to let the ends stand and soak up primer for a day and then be properly painted.

When repainting, I would just leave it, if you can't see the end, no new paint is needed there.
