Protecting MFD

[wcarrothers1]

Well I've cut a few things on my machine so far and after dusting it off I've noticed in some areas the mfd isn't as shiny in it's surface then it was. I'm using some scrap ply wood to stand and support my work pieces up off the table so the bits don't dig into the mfd for some things I'm doing and in the locations I've put some of them I'm seeing the MFD wareing a little..

Just curious if anyone has come up with a best surface coating for the MFD tables. Maybe urathane or something else? I really would rather not apply bondo or anything like that and have to resurface that after applying it...

But would do that I guess if it is the way to go..

Maybe some are putting laminate or something else but I figure there must be just a epoxy coating of some sort that would be good enough.

I use a product made by Morrells here in the UK. It is an acid curing resin, similar to cellulose. Within one hour of applying, it can be rubbed down without clogging the paper. It is brilliant stuff and two coats on MDF is all that's needed. I am sure there must be something similar in the States - maybe Morrells is available? Web site: www.morrells-woodfinishes.com half way down page 9 of the product guide you will see '440 High Build/Fast Dry A.C.' this is the stuff I use and I can highly recommend it.

With a few more coats on the MDF, I also use it for pattern making and take fibreglass moulds from the MDF. Release agents work just fine over the Morrells.

Dear Mike,

Looks interesting. Thank-you.

Does the MDF suck it up like a sponge on cut edges or faces? Most solvent based finishes seem to disappear into these almost instantly. If this finish doesn't, it could be a real winner.

Martin,

The first coat does disappear somewhat but the solvents flash off very quickly and leave behind a very viscous, sticky resin that cures very quickly. The second coat, even on the edges, does an excellent job of sealing. It brushes on very well but you do have to be careful not to over-brush the parts already covered because it is easy to drag the resin once the solvents have flashed off. Work quickly and keep the leading edge wet is the best advice.

If you are set up for spraying, it sprays brilliantly but do wear a mask!!

Yikes Mike, that was a fast turnaround!

Looks like I'm going to be giving this stuff a whirl . Alas, I'm not set up for spraying.

Thank-you

Best wishes
