re: Retooling Shed - Painted Plywood Floors

If the plywood is in good condition a cheap way to make it look really good is decorative Shou Sugi Ban. I say decorative because most actual Shou Sugi Ban cars the wood fully black. I wish I had pictures but we did it on a friend's studio floors and with poly on it it looks fantastic. There are a ton of resources about how to do it decoratively, it became popular 5-6 years ago.






You can also add stain



This is actually plywood flooring
