Topic tags/keywords: resource question plywood finish thick

Hello all,

I built a rocking bench from plywood so the grain of the ply shows across the seat of the bench, and on the hand rails. I know any kind of thinner finish, the wood will just drink it and ask for more.

I am looking for something with the consistency of honey, that dries clear and looks like glass and can be sanded and buffed to apply to the bench. Any ideas? I went to my local Home Depot, and they recommended Bondo Glass short fiber filler. I couldn’t understand why they would recommend that. It doesn’t dry clear… So I stopped asking their advice.

I have attached a photo of the bench in it’s current state of progress so you can see what I’m talking about.

Seal with shellac (or an initial coat of finish) to prevent absorption. Spray it on if you can.

Then, apply a film finish of your choice. It’ll build up.

If this is an outdoor piece, I’d use a marine varnish (at your local boat store).

What do you think of the stuff in this video Cosmicsniper? A Facebook friend suggested it.

Yeah. that’ll work if you want to pay the price. Epoxy is often used this way to build thick finishes on bars and stuff. The only problem is that the application method might not work for your bench, at least for anything other than the seat. It takes a while to do it with traditional film finishes, but it is doable if you seal the wood first…which shouldn’t be that big of a problem with plywood. It’s not like there are open pores wanting to drink in tons of finish.

It’s a nice bench though!

Thanks a ton. I was looking into the epoxy, but yeah it was like 50 bucks for the amount that I needed. I will look into the shellack/marine varnish application.

BTW, I used a similar epoxy film finish to make a plaque with a mosaic of old stamps many, many years ago. Turned out well.

I found some at Lowes for a decent price, and I think I will stain, then put that stuff on there with a foam brush in a thin coat.

Cool. Be careful with the stain. It will blotch on plywood. I’d washcoat it with dewaxed shellac first.

Here is one of the most popular epoxy finishes http://www.westsystem.com/ss/

It’s best to apply in two coats the first coat thinned 50/50 let dry do a light sanding with 600grit and wipe down and apply a second coat full strength.

It looks like however I do it, I would be wise to shellack the wood first. I will post the updates in the blog section for the bench, and the finished bench in a finished project post. Thanks a ton for the tips and info.

I have put a brushed on tung oil finish on cedar. Then applied a second coat of tung oil and put it on very very thick. Like a puddle, so there were no brush strokes apparent. I let it dry for 15 hours and it came out looking like high gloss glass.

I am fairly new to finishing wood, so I have never heard of tung oil I will check it out. Thanks.
