I am finishing a new cabinet bottom for my Williams Funhouse. I'm using 1/2 inch "sande" plywood, which has a very nice finish. Should I protect the plywood by sealing or coating it? And if so, what product(s) should I use?

Also, any thoughts on whether I should screw the bottom into the cabinet in addition to gluing it?

Thanks,

Harold

Ai replaced a bottom in the passed and I glue it in then I made up small wood for around the 4 sides and glue them in also just because I didn't want any nails or screws in case it would spit or something

Thanks very much. Should I seal or coat the plywood to preserve or protect it over time?

I redid the bottom on a game very similar to the method you're using. Glue alone will be hold the bottom in just fine as long as you use enough & clamp it up well.

However... If you are replacing decals, then shoot some nails along the bottom with an air nailer for added insurance. A little mechanical support is good. But the air nailer will also help secure everything & ensure a nice tight joint as the glue dries. Don't get overzealous, a few nails along each side will get the job done.

One more question. If I use a satin polyurethane on the plywood, will wood glue still work to adhere the plywood bottom to the cabinet?

I would glue before sealing.

As long as you've done that clean lip glue will hold that bottom in perfectly fine. Wood workers use nails to hold until glue sets... just let the glue dry on its own before moving.

Factory look is unfinished wood. Leave it bare. You don't need to be protecting against moisture, etc.

Thanks again. Yes, I just confirmed through google (not nearly as good as Pinside) that wood glue doesn't work well on poly.

Happy thanksgiving to everyone who helped me with the new bottom for my pinball cabinet. It’s all done: sanded, glued, no screws, no finish, and 1/4 inch trim all around. Thank you pinsiders once again for you help.
