How do you engrave concrete bricks? What is the process for doing it yourself?

Answer 1

You could use a die grinder with a masonary pointed bit. Sandblasting is also used.

Answer 2

Most contracted/Dedication bricks are either engraved with a template, or molded using the raised engraved names, etc.

USUAL Brick is not so tough that you couldn't attempt it as a DIY, I'm not sure, in all my years, that CONCRETE Bricks are Usual,,, but not knowing your purpose, or the substance of what you want engraved, the process might be more labor intensive than you wish, and less than cost effective.

If it happens that you want TEXT on a brick, you might inquire about Router bits that would do the deed, or Dremel bits to accomplish the task. In any case other than freehand you probably should have stencil templates made specific for what you require.
