I'll get some pics up when my project is finished, but I have a couple of questions for the knowledgeable folks out there.

I used Sherwin Williams 1000HS Epoxy on my floor, and the containers actually say, "Sherwin Williams 100% Solids Epoxy 1000HS". When I go online to look at cure times, it says:

Volume Solids, mixed: colors—65% ± 2% may vary by color clear—61% ± 2%
Weight Solids, mixed: 74% ± 2%, may vary by color

I'm now wondering if "HS" is High Solids...but wonder why the container said 100% Solids????

Also, I am in Dallas and it has been 105 for 16 days straight. It was applied this morning about 8AM (full prep was all day yesterday). I walked on it just now and it did not leave any foot marks, or transfer any of the epoxy to my socks.

Can I lay some painters sheets down tomorrow and paint the walls, or should I wait?
(Drying schedule below)
Thanks!

You should be fine to walk on it tommorow. When your done painting your walls just take everything off the floors including drop cloths or whatever, so that the solevents in the epoxy can gass out and fully cure. I used sw macropoxy and walked on mine the next day without any problems. The sweat in time is the amount of time you should wait after you have (a) and ( b) mixed together till you begin to use it.
