I had thought about using a few coats of primer, but couldn't decide on which would be the best. I know Behr makes it, but again, I wasn't sure if that was a critical step...seems like the people who do it without primer have good results also. I am up for any last minute recommendations!
Edit: I also took note that there are an excessive amount of chips and a seemingly excessive amount of chip "dust" at the bottom of each bag. I used a spaghetti strainer and dumped the chips in that, filtering out the larger chips as I plan to use those and not the dust and smaller chips. A relative has a professionally done floor and it looks like they used only the larger chips. After filtering, it looked like it eliminated about 1/4 of the volume of the chips.
