Looking for best ways to make sure floor mural on concrete doesn't wear down

Hello guys! I recently got commissioned to paint a logo on the smooth concrete ground for a client and want to make sure it's done properly so that it doesn't wear down too fast. from my research I've found that some people just recommend a good scrub while others recommend etching with acid. I found the differing ideas to be pretty overwhelming and was wondering what you guys would do in this situation. Thanks in advance!
