I'm tossing the idea around on using OSB as the finished floor. Cut to squares and rectangles to make a geometric design on the floor.
DETAILS:
Double wide mobile home in New Mexico. Swamp cooler in summer raises humidity inside. OSB will be sealed, sanded, stained and finished with polyurethane. What are the YES you can or NO you are nuts replies to this idea?

Ever see that reality show called Big Brother? Yeah the wife watched it. Last season I watched part of one and on the walls I saw OSB, no kidding. All sealed up and finished...I was like...heck thats osb on the walls! Looked kinda cool. I've also seen hardwood plywood cut into strips and top nailed and finished, Cost is fairly cheap.

I've seen an OSB finished floor in a magazine. It looked really cool. It wasnt geometric designs, that would look even better. I kinda question how a stain would look, the chip variation was nice. Maybe they used natural stain ?

Hey guys, maybe we should start up a pre-finished parque OSB mill !

I have no problem with this idea at all, except for some possible splintering over time along the edges but im not even too concerned about that.
For added feature, you could bevel the edges of the panel or even add a 1/4 inch wide strip of walnut or something.
Really, for the type of project you have in mind, you are only limited by your imagination, and the heck with what anyone says.
