Best way to grind concrete wall seams?
This is an inside basement wall below ground ... I recently, had a 7' non-structural crack sealed as it would rarely seep water, but was nuisance when it did. Basement is now dry & I wish to paint 2 walls. Issue is ... every 2 feet there is a seam left behind from when the foundation was poured. I would like to grind down these seams prior to painting the wall. I am considering a 7" right angle grinder with a diamond cup wheel & grinder hooked to a Shop-Vac. Will this do it or is there a better safer way? Of course I understand I will need to wear proper Eye, Ear, Nose protection etc. However, any guidance on best way to get this done is welcomed.
I would suggest you consider parging your wall instead. Below is one of several sites that address this method.
I can tell you from experience, it is much easier and looks better. Trying to grind the aggregate in concrete will wear you and your tools out. Any concrete contractor will tell you that parging is the best way to get a good result.
