Question about Festool Domino joints

I would defenitly apply glue to the joint and not ONLY the dominos. I wouldnt go overboard with it, because like you say you dont want it to bleed. But I would apply a very thin film just so you get the bond.

I always apply glue to the dominos and the recess they fit into, but not always the other areas, depending on the size of the pieces and the application.

On the example you mention, I may only use two dominos, and as already advised, it would not hurt to put glue on all the contacting surfaces.

I don’t domino, but I do glue. You can run a little chamfer around the
mouth of the mortises which gives the excess some place to go – I
do this if I want a real clean glue up and I haven’t opted to finish before
assembly (which is another option which reduces glue squeeze out as
a problem). Applying glue is a bit of an art because wood porosity
varies, as does joint tightness, glue viscosity and so on. Most guys
probably use too much, but too little is bad too. I put glue on both
surfaces of a well-cut joint, but not a lot usually.

”the excess, if it gets where it shouldnt be, it shows up when i apply the finish.”

Are you doing something with squeeze out such as rubbing it with a wet rag while it’s still fluid?
You know like the instructions on the titebond bottle say to do?
I wish some one would tell them that is a baaaaaad thing to do.

I leave the squeeze out alone. I mean I leave it alone like it was a fifteen foot salty crocodile and I was nekked and barefoot creeping past it. I wait for the glue to mostly harden off (No fluid core in the globules and drips) then it lifts right off with a slight prick from a chisel or knife leaving nothing behind. Sanding finds no more glue and finishing discovers no glue.

When I wait till it’s fully cured and hard it’s harder to get off but it comes off leaving no residue.

Years ago I wiped with a wet rag while it was still fluid following the instructions I read somewhere, prolly on a bottle of yellow glue – those same instructions are on the titebond bottle today and they are just as wrong today as they were 20 years ago.
Wiping serves to rub glue into the pores of the wood where you won’t get it out without sanding a lot of stock away.
In the words of Sheriff Buford T. Justice:
“Don’t do it.
You can think about it, but doooooon’t you do it. “

I use a wet sponge to clean the joints and it seams to do a good job removing all of the excess glue that squeezes out.
