Temperature Changes

Post by Dave74 on December 13th 2007, 11:58 am

I rolled the first three coats with the outside temperatures in the 30's and snow on the ground and an unheated garage with garage door open. I didn't have any problem with orange peel or runs when rolling it on and it went on like glass. On coat four, a warm front came in and brought temps up into fifties and sixties. I just went out to color sand and put another coat on, and I got an entire trunk lid full of orange peel.

The only thing that changed was the temperature. So, just an observation that could help someone else.

I think that the humidity also plays a role. If it's more humid one day than another I think the solvents in the mineral spirits will evaporate slower so you'll get better planarization. The downside being it may take forever for your paint to dry.

hmmm I painted mine in a garage at around 75 degrees. I noticed when I first started that I got a lot of orange peel if I mixed in a little too much paint in the ratio. Were you using the same batch of paint?

So what's the word on the paint and temp? I didn't think warmer temps would make a difference.

Well paint is going to dry quicker with a warmer climate. The way I see it, warmer climate = quicker dry time = less self leveling. If your painting at a slightly cooler climate then the paint doesnt dry as quick and it extends the time the paint has to level out. If you use thin coats at a cool climate then you should have very little orange peel. In theory that is.
