Did you grind the floor to Expoxy it?
 

Im going to paint the garage floor tomorrow. So far I've removed old paint, and cleaned the floor. A lot of videos on the internet have people grinding the floor before putting paint down. Directions on my kit dont mention that i have to. Do you think its necessary?



This is what im using:

I went to home depot to see if they had a grinder and all the have is a hand held one and you have to buy the blade at $150. No way in hell im grinding a over size two car garage with a handheld grinder.



What do you think?
