Why in the world are you spraying trim three times? Unless it's bare wood, no primer needed, and BM Advanced is made for one coat, especially spraying.I'm going to be spraying my interior trim with BM Advanced. I first need to shoot it with primer and then I plan to do 2 coats of the BM.
I normally only spray doors, so I've never really had to tape anything off for more than a day, but I plan to shoot primer in the morning, then the first coat of BM in the afternoon and the second coat the following afternoon. Will I need to do anything special as far as masking goes?
Also, any recommendations for a good sprayable primer? I'll most likely be using a 311 tip on my graco X5 for this project.
