00:32 - Prepare the Plywood Subfloor for Epoxy Application.
01:28 - Select Epoxy Floor Coating System and Products.
02:10 - Fill all Plywood Gaps, Cracks, etc. with Epoxy Crack Filler

Dude thank you so much. Being a young homeowner no one wants to give me solid advice or help because they think I’m some stupid kid. YouTubers like you keep my home in a great looking space and can’t wait to have these in my shed!

We put industrial epoxy (I forget which) over a US penny floor in our kitchen. I was too cheap to buy those expensive shoes for a one-time project. I took dollar store flip-flops, traced around them on a piece of scrap plywood, cut out the shapes with a jigsaw, then attached the flip-flops to the wood with leftover drywall screws through the foam, pointy end to the floor. I made one pair for myself, and one for my husband. They worked a treat and cost $2 total instead of $100/pair.

Great job Andrew. Wow! Your shed is nice enough to live in! Very detailed instructions too, and i'm sure this will help a lot of folks apply epoxy! It's super easy and so fun! Can't wait to see your next video!

Excellent tutorial, and very much appreciated. I'm using Spartan products over a 290 sq ft OSB floor in my woodshop and if anyone's interested I can speak to getting that material ready for epoxy. (Plot spoiler: I wish I had plywood instead. But you work with what you got.). Before anything else I used Spartan CF100 crack filler for any gaps between sheets and countersunk nails (should have been screws, but I learned that too late). Spartan recommends applying KILZ2 (not 3, for whatever reason) before laying down the Flex. Needed two gallons.

Next the Flex, which I had trouble spreading out and distributing evenly maybe because I didn't have a rubber notched squeegee, only a notched metal one for concrete...useless. So regular straight edge rubber is what I used. **One thing you might want to stress is how much time you have to spread the stuff before it starts to set and becomes super viscous.** Don't dilly-dally. I barely made it. Also, Spartan indicated one gallon would be enough to cover my 290 sq ft but in hindsight I wish I'd had two. It's good enough, I guess.

I'm applying the WB primer today. Will let you know how the rest of the project goes. BTW I'm not doing metallic, just the flake "cast" as they call it mixed in with the Clear. Also adding a can of Spartan's non-skid. At this time I'm not planning on HPU top coat. Will let you know how it goes. Total cost of Spartan materials: about $1000 (2024). Not cheap, but good.
