I built a toy box with a top made from MDF plywood. In the center of the top I routed in a checker board. Unfortunately when I sanded the checker board squares, I sanded some of the top MDF layer off down to the wood in some spots. I lightly sanded these spots trying to blend it in but when I painted the top, these spots really show though compared to the rest of the top. Any suggestions on how I might blend these spots in so that when I repaint the top they won’t show through?
Thanks

When you say you sanded the top layer off to the MDF you mean the opposite right, you sanded the wood veneer off down to the MDF. I'm assuming you used a birch or maple ply with a MDF core. If this is the case, and you are painting the top, you need to seal the exposed MDF and maybe do some filling. Try Bondo, body filler and for the sealer I usually use Zinzer White-Pigmented shellac. If you work at it you should be able to make it go away
Good luck
To me it sounded like the post was talking about MDO rather than MDF - perhaps he sanded through the kraft paper facing on the MDO and hit the plywood core?Justin Fink - FHB Editorial
I missed spoke. I was using MDO and sanded through the kraft paper down to the plywood core. Sorry for the confusion.

OK, thanks for clarifying that. I guess my repair suggestion would be the same.Good luck
you might try using an oil based sanding sealer over the MDF portion. once dry sand lightly then repaint. That will create a smooth top to even out the sheen.
That technique has worked well, since you essentially made the top a machined edge.
