I just completed a new router table top. I used mdf for its construction and laminated the top and face of the fence.
Would it be advisable to seal any exposed mdf with shellac to prevent moisture absorption or is it not necessary?
Thanks.

I would say YES! Seal the bottom! I have several router tables set up for various jobs.. I have only sealed the bottoms with shellac.. I have no problems with the MDF. OK so you cannot get them VERY wet!
If you went through all that, why not just 'bite the bullet' and laminate the bottoms also! I'd think a good coat of primer and paint would work also.. But what do I know?
EDIT;; Good idea to seal the edges ALSO!

I banded the edges with 3/4 oak. Sort of following the design popularized by Norm.
I will put a coat of shellac over the raw mdf.
Thanks for the help.Webby
Here is a probably poor qyuality pic.Webby
Definitely seal it. I made a table a few months ago: formica on top and bottom, hard maple edging. I put a water-based varnish I had lying around on the plywood (in my case) that was exposed when I made a cutout for the router plate. I would think anything exposed should sealed with whatever you've got around. You don't want to risk any warping.Norman
Thanks, I just put on a coat of shellac.
I built it last week and had to put it right to use on the base of this foot stool.Webby
Looks like a ockler.. Nothing wrong with that..
You mean looks like a rockler?
I bought the track the knobs and two mitre track featherboards from rockler. I am using the roussea plate that I have used for years. I would like to make a stand or cabinet, but I am so limited for space, we will see. I also need to add some dust collection to it.
I plan to upgrade routers at some point, and will probably use a rockler plate, then everything will match. Lol.
Those featherboards are a good value and I am looking forward to using them. I also bought a track for my auxiliary fence that I use for the dado.
It is not perfect but it is perfectly functional. Which is what I really need.

I would advise you seal. I built my table out of two 3/4 mdf pieces sandwiched and toped with formica and edgebanded with oak. I sealed the bottom with shellac. Its been a couple years and she's still flat.
If it moves, tax it. If it keeps moving, regulate it.
And if it stops moving, subsidize it.
