Grind marks - move on or keep working

[vidkidruss]

Hi all, I just finished grinding and I'm trying to decide if I can move on to finishing or if I should work on the grind marks. Some info on the job:

- Plan was to put down a tinted coat of Nohr-S Polyurea, throw some mild flakes, then top with clear coat of Nohr-S Polyurea with grit.
- I'm not trying to create a work of art, do want it to look good but it'll be a working home garage. And I want to get this finished.
- The main area is about 330 sq ft.
- I used a 5" disc to do the grinding as there was a lot of coatings, etc across most of main floor.

I know the more flake I use, the less marks will show but I didn't want to put a lot of flake. I was considering doing the Diamabrush rental at Home Depot. But I didn't know what is the grit of that concrete prep brush they rent and would it actually help the grind marks. Don't want to waste money on the rental if it won't help.

Would a primer be an option to help mask some of the grind marks? However, I don't want to negatively affect the Nohr-S application as the concrete is nice and ready. I've also considered going back with a less aggressive brush attachment and trying to spot prep the most marked areas.

I realize this question is a bit subjective as everyone has different opinion on what is acceptable vs not. I'm just trying to not get bogged down again on the project.
Thanks for any tips!

How much of your floor will be visible most of the time?
Will those areas most likely be covered by machinery, work tables, vehicles, etc.?

How OCD are you?

Lol, this project is doing a good job of helping me reign in my OCD. Ha!

I would say that much of the area will have either rolling tool boxes or in the cases of the sides, storage shelving. The main part, yes covered by a vehicle I'm working on. So plenty of visual distractions as opposed to looking at an empty garage floor.

"I'm not trying to create a work of art".... Coat it! You'll see some of the imperfections but nobody else will.

Sounds like you have answered your original question.

Shiftless, I guess you are correct. Working on all these DIY projects in a bubble gets a person second guessing everything. At least it does me, lol!

I admit to overdoing things myself once in a while. I rationalize by thinking that I am just practicing for the next time I need to do that job and I just need the experience.

It's the curse of DIY, you spend hours with your nose 4 feet from your floor seeing every minor imperfection then you apply a coating and every gnat, fly, mosquito within 10 blocks shows up to "help"! When it's all done you will be able to see a fly wing stuck in the topcoat from 100 yards away.

i had some really bad divots and boogers on one section of my floor that we had to wait for another truck and it was a mess. My floor was a dark blue and i just made sure after the first coat of color that everything was covered. the next day i put another coat in that corner of the shop to add some mil thickness and haven't thought about it for five years until i read this thread. So give it a coat and decide from there. My floor was a dark blue so covered a lot.

1 - if the grinder marks show through and you notice them, it'll ease the pain the first time you damage it
2 - most likely it'll still look better than 99% of your neighbors/friends garages

If it's a working garage, I'd just send it if you're confident the prep is good
