Marco trashed one side of his work table and decided it would be a cool experiment to see if he could give his MDF table a nice polyurethane finish...this is his story.

Hey --- I'm glad you made this video. MDF has a nice look to it for the table top (shipping table), I'm looking to make. I was wondering it it could be made smoother with Poly.....and you answered my question. I have to say, I wouldn't have predicted 5-6 coats of polyurethane, but hey...it got the job done. Thank you!!!

Use shellac to seal the mdf. It flashes faster than the mdfs reaction. It’s great for sealing the mdf “end grain” for painting.

@EverythingHouse Жыл бұрын

Great tip! I'll try that next time! Thank you!

Are you insane?? Shellac costs over $70 for a measly gallon! sheesh. Use diluted Titebond One (PVA) instead.

@mikebaker75 3 ай бұрын

@@timault8209 pva glues, even when diluted won’t impregnate the “end grain” fibers and stabilize it as much as shellac. Then if you get it wet….still have issues. Shellac can work as a sealer and a primer in this situation. You’ll be able to block sand it and go straight to paint if need be.

You can very light sand the final coat by hand with fine grit to get an ultra smooth finish on top top layer.

I do a lot of "learning things " when I'm in the shop. Guess that's part of the process. That's how these old guys get so good. I am going to make some router templates out of MDF. I was thinking about varnishing them. What do you think about that. Someone on Facebook told me to put CA glue on the edges which sounds like a good idea but that's a lot of CA glue.

@EverythingHouse 2 жыл бұрын

"Learning things" are my favorite. I'd make them out of plywood. MDF is just too brittle. No tensile strength.

I have some boards I used for fabric cutting tables of 48 by 72 inches and they are about an inch thick. The board top has water stains and scuffs. Do you think they could be “saved “ cleaned and make them look like new again ?

Hi there! Could you please write down the products/steps you use/you make? I'm doing a bed structure, like a podium to fit the bed in. I need it to be "strong" enough to walk on it, a varnish that it won't fade, because we are gonna walk on in (barefoot). Thanks!

@EverythingHouse Жыл бұрын

I might go with plywood if you're going to walk on it. It's much stronger.

Any thoughts on how an oil based poly would do on MDF instead of Water based?

@EverythingHouse 2 жыл бұрын

probably better. If you don't thin it down at all, then it will probably absorb less meaning less coats will be needed. Try it and let me know!

@karlopopovic810 Жыл бұрын

What about glueing two MDF boards at a 90degree angle? What glue/sealer would you use for it to be water resistant?

@EverythingHouse Жыл бұрын

The only way I would do that is by adding a strip of solid wood adjacent to the 90° angle, so that any pressure is shared by the entire piece. Particle board is not strong, so you have to supplement.

Great video!! I'm in the process of sealing my mdf bench top now, so this came in handy.👍 I have a question tho, what sandpaper grit did you use after that first coat?? Thanks!!

Happy I could help! Not sure exactly, but I would start with a 120. Let me know if you need anything else!

What did you spray on it after the last coat?

@EverythingHouse Жыл бұрын

water based polycrylic is also available in a spray can. It's great for the final coat!

Maybe hand sanding it between coats would be more effective. Just enough to get that white residue up for that mechanical grip.

It's possible.

You are meant to apply an MDF sealer before varnishing or painting

That looks like water based Poly Urethane. I'd choose a thinner based one.

Absolutely. I like oil-based as well, just takes a week to get a good finish, I didn't have the patience this time.
