I've been diving into some videos about using laminated MDF sheets for workbench tops and noticed they usually recommend finishing with poly or similar sealants. I'm curious why they don't often suggest topping it off with Formica or another plastic laminate. Considering Formica can last for years on kitchen countertops, I have some sheets on hand and wonder if there are any downsides to using it on a workbench surface besides the cost. Would it be a bad idea?

I used an old kitchen island top as a workbench for ages. If you have it lying around and know how to handle it, just go for it! It might turn out great for your needs.
Formica can get pricey compared to an easy shellac finish that’s much cheaper and can be refinished. That said, I’m on the lookout for formply for my next bench build—kind of like melamine but with plywood.
It really depends on how you’re using your bench. Many folks say it’s mostly about cost. If you’re hammering a lot, it might crack. Plus, if Formica gets damaged, you’d need to replace it entirely, whereas you can simply sand and recoat a poly finish. I actually have Formica on my outfeed tables, and it holds up pretty well for my needs.
I have some reservations about using laminate since it can scratch projects, unlike MDF which you can repair with Bondo. Plus, laminate can be super slippery, making it hard to keep things in place. Just something to think about!
Formica is cheap and easy to apply, but remember that glue doesn’t stick to it very well, so be cautious with how you treat it. I've had good luck using it myself!
Formica has its ups and downs. It’s hard and resistant, which is great for paint and stains. But it's also slippery, which can make holding items tricky while you work, plus there's a higher chance of your tools getting damaged or cracking if dropped. Personally, I think the negatives might outweigh the benefits, and that’s why many woodworkers stick with traditional wood tops.
