protecting a new MFT top
« on: November 02, 2022, 08:18 PM »
I just finished creating an oversized MFT top out of MDF.  In the past, I used to apply a coat or two of paste wax as a protector to keep glue from sticking to it.  Is there anything else I should be considering like applying a coat of lacquer sealer first or maybe wipe on poly?  What works best for you?

Based on some suggestions I saw, I applied a couple of coats of dewaxed shellac on my two MFT tops, being careful not to let it get down the holes.  I’ve been happy with that.

did that prevent glue from sticking to it?

While I am not in the habit to let glue dry completely on my primary 2-MFT set up, I have been able to scrape it up easily after glue-up is complete. I consider my MFTs a working surface so don’t expect a flawless result. But again, I’ve been happy with what the pre-waxed shellac does.  If I spill something unexpectedly, it’s much better than before I put the shellac on.

If I have a really sloppy glue-up, I place a combination of one to four 2’x4’ 1/2” plywood sections on sawhorses that have 3 coats of dewaxed shellac on each side of them.  I used the LR32 system to drill 20mm holes at 96mm intervals on them so I can use Festool clamps where I need them.  When I’m done, I scrape up the glue, and the sections and sawhorses easily fit in a small corner of my garage.

I've done 3 to 4 coats of tung oil and have been happy with that.  Easy to apply and glue pops off easily after it's dry if you missed it previously.

Being a "if it goes in my shop slap some Osmo on it" guy I've recently discovered it really does a nice job sealing up MDF.  Now with that said shellac+pastewax costs next to nothing and works like a charm as well.

I'm a hit it with a hammer and move on type, it is a work surface after all and it will suffer damage so I may as well start with the first damage.

I’ve used Seal Coat and Osmo with excellent results.  While it is a work surface I still like to take care of my stuff.
