Does Heat Accelerate the Curing of Paint


I have 1 panel that needs a cutout....
I plan to prime and paint this panel....knowing the the cabinetmaker will be back to make this cutout.

I don't want to paint knowing the paint will very well shred.chip when it makes the cutout.

However, does HEAT accelerate the curing process.
The cutout will be done via router on MDF.

If heat does accelerate the curing (hardening) I may potentially paint this panel and put it outdoors in the bright sun to bake...
Paint will be Aura Matte

Sure- the sun will harden it up. So will moving air. Humidity will slow it down.
Kind of common sense, no?

Ha. U tell me. There are some rooms in which I can tell the paint is not cured....you pros see this everyday. it's kinda like drywall. It has a different feel. There is a slight ~cold~ to noncured paint.and it does feel difference on the surface on cured paint . I'm just talking Aura though..

Cured and dry to touch and dry to repaint are 3 different things.
But I bet if you read the can it would tell you what is what..

I'm talking about 2 week old paint versus 4-5 week old dried Aura Matte.
Just saying...it has a different feel when you put your hand to them. I never A/B noticed them until now ....as I am painting alot of rooms at various stages

Go read the can and write here what it says for full cure.
You can do it!

Thickness can play a factor.

Virtually all chemical processes are sped up or slowed down by presence or absence of heat. That said, too much of either are bad. Better to put the piece in a low humidity/good airflow environment than bake it in the sun.

I ended up baking it..
It needs another coat of paint anyhow - so UV discolor was not a concern.

These were flush access panels that blend with the wall.
Cabinetmaker is going to take a router to it - and cut out the holes for the dials and such.
I painted it this weekend and knew the paint would shred if it was not *baked* as this stuff takes awhile for it to *dry* if not bond-bond to the surface. Baked it - just to minimize the shredding

Some depends on your cabinetmaker. If he uses a down spiral bit, most of any shredding would happen on the bottom side. Compression bit should leave almost none on either side.

A good test for cure is to use a fingernail test to see if it leaves an indentaion. Most latex paints cure in 30-45 days. As previously stated, humidity and heat slows down this process.

Yeah..I did not know how long these new formulations take...
In the midst of renov. and finishing. I leaned a solid slab door on one wall that was 2 weeks old....and when I leaned just the edge into the wall and lifted, I knew it was not cured....as it left a slight edge indent/paint lift on it.
