Topic tags/keywords: question joining

I’m working on my first big project which includes a 3/4 plywood counter top. It wraps around the room so it couldn’t be one piece. I also lack experience doing this so the seams between the pieces aren’t all perfect. I have a few 1/32 – 1/16 in gaps between some of the pieces.

Should I fill them with something before applying the finish or just chalk it up to a learning experience?

Ideally you would trim edges straight and use biscuits if you want it perfect.

Short of that, yes, fill it that gaps aren’t that big.

The edges of plywood do not take strikes, hits, and collisions worth snot. they will become frayed, the veneers will start to crack, and in short time they won’t look too swell.

What most people do is edge over the edges with solid wood. Various edge treatments can be done, a few seen below.

You’ll need more than shellac. Shellac has zero protection qualities. Why are you shellacing? If this were my project this is what I would do: Fill the spaces with a quality filler such as TimberMate. Sand the entire top to 180 grit. If you want to use a stain you may want to consider General Finishes Gel Stain. It is VERY easy to use. GF has a how-to video on their web site. Use a top coat such as GF Gel Top Coat, Armor Seal, or some sort of Urethane top coat.

If the filler doesn’t take the stain as well as the rest, use an artist’s brush and put a bit of stain right on the filled area and do not wipe off the excess.

Make sure ALL the stain is dry before applying top coat. If the stain is even a little wet the top coat will “lift” the stain. Ask me how I know.

I’m planning on using a solid wood edge.

Re: shellac: Someone had suggested it on another forum post where I asked about finishing. Thank you for the warning.

Is this a plywood, Solis wood top?

Field joints, etc?

Maple plywood.

Field joint?

The counter sections are butted together with supports underneath glued and screwed.

Hmm, is this just like shop furniture where you aren’t concerned how it looks in a few months?

No, I’d like this to look nice for a long time. It may be my first big project, but I’ve put a lot of work into it.

So you already made the field joints and they aren’t tight?

Scribing isn’t an option at this point. I need to fill the gaps and then finish with something that will hold up and stay looking good under sewing and crafts.

You might as well make a groove and fill it with an alternating piece of wood like walnut.
