In remodling our master bed room we decided tp paint the plywood floor we could’t afford to carpet. We filled in the unevenness with bondo. Let cure well. Sealed it with a good primer. Painted it the color of choice & then stenciled roses all around the edges with a 1/4 circle facing the corners & a Hollow heart 1 in each corner of the room. It turns out we liked it better then carpet! And it was a whole lot cheaper!!
If you want to make this last longer you may want to consider a clear sealant (like Polyurethane). I have used a similar technique on the home of some very good customers of mine to great success. You can also make good counter-tops out of mdf which is painted then sealed.
