Paint the concrete planters.

BHUPENDRA MUNDELE

Hello. I am hoping to launch a beautification project in our city. One goal is to paint the concrete planters. BUT members of the community have concerns about what paint to use and how long the paint will last, especially given our proximity to the ocean. The planters are large and are already planted. I do not have additional information about the type of planter or prior sealants, etc. I would love to bring some vibrancy to the area, but need to address these concerns. Any guidance sincerely appreciated!!
