Hey guys, I just about got my router table done, formica on the top, hardwood trim on the sides and was going to apply shellac to the bottom.

My question is do I need to apply shellac to the side walls of the router plate insert hole and the rabbet it sits on or is this overkill?

It’s overkill imo. I have an MDF router
table top from Rockler and I don’t think
it’s sealed. As long as you don’t leave
it out in the rain it should last a long time.

I’m not sure about shellacking the bottom
though. Prevailing wisdom on these matters
is that panels should be laminated or veneered
on both faces if they need to stay flat.

I would seal it. It only takes a couple of minutes and dries very quickly. It looks better and resists moisture.

I would treat them with some sort of sealer. The MDF is relatively soft and adding a hard finish to those cut out surfaces can only make them stronger and more durable; at least it did mine. I would also seal the bottom although you don’t particularly have seasonally changing humidity problem in most of Calif. I use a top layer of 3/4” MDF on my work benches and I seal them with poly to make it more durable and resistant to glue and other spills. Shellac, poly, or lacquer will all work so use what you may have.
