Sealing MDF Structure

[scratch_6057]

Building my first 3 axis router table, the frame / mechanical structure to be
mostly ¾ MDF and some 1/8 aluminum sheet. As I’m located in an area which
is subject to relative high humidity at times (Atlanta, GA ) I intend to seal the
MDF with epoxy fiberglass resin, one coat on each part, then a final coat
when all the MDF parts are assembled.

My question is, does anyone think I would gain anything by applying
fiberglass cloth to the final structure in addition to the epoxy resin?

Hi Mike,

The fiberglass cloth may reinforce the seams a bit, but I can't see a big advantage to it. You may get better results from a good marine epoxy (one made sor encapsulating wooden boat hulls, this is the one I use on the boat)

On my router table, and I have the same humidity problem, I used a heavy coat of kills with mold inhibitor followed by a coat of a good hard spray enamel (rustolium or something like that) to give it some color and a nice look.
