Spraying 5 piece panel doors

[alice]

I’m going to build some 5 piece panel doors and spray them with a Benjamin Moore scuff x paint.Would like some advice on limiting cracking if any around panel and frame if possible. Materials considered 5 piece all mdf door or 5 piece poplar frame with mdf panel.

The face side of the rail and stile grooves, back cut/sand them so that edge is not tight to the panel.

You can caulk the seam after priming.

There are cutters available that will easy the edge when you make the rail and stiles.

I recommend hard maple over the poplar.

What’s the purpose of caulking flexibility,gap or both ? Is the Reason for maple for better finish product not movement.

Thanks Tom

Allows proper bridging and inevitable gaping between the panel and the rail and stile.

Yes better finished product and more resilience to everyday use.

What caulk do you guys use?
Curious if there would be a different choice for Solvent or WB top coats?

I have gone back to using Big Stretch under the water borne. I had hopes the new urethanes would work, I was getting finish checking even after days of caulk cure.

On our new doors with the relieved edge, there is no need for caulk.

Key thing-----caulk after priming.

Can you describe that profile a little more?

Okay. Thanks for the info.
Was curious if you have ever seen a router bit set that has the relieved edge. I dont have a shaper.

 

[tjbnwi]

No I have not. None of my router bit sets have the relieved edge.

Yah. Me either. Too bad.

It is easy to relief the groove with a block sander. I use one of the Festool block sanders.
A few strokes with the corner of the sander in the groove quickly knocks the sharp edge off of the pieces.

Is this what you are looking for?  This is the set I have and use.  I love it.

Yes, some (older) Freud rail and stile bits have relieved edges.
It is difficult to actually figure out which one as their catalogue is not as descriptive as it used to be.
