Hi everyone Merry X-mass. I have been painting semi custom new homes for a small builder developer. 2600 to 3000 sq ft. We come in after the trim package, floors, and tile are in, don't ask me why thats how he builds:blink:...ON the first home we filled nail holes, primed and BR walls and ceilings, BIN on raw MDF, sprayed finish enamle on doors and trim, back masked trim and sprayed and BR ceilings then mask ceilings and spray and BR walls. It was not easy papering off ceilings and I got over spray on ceiling. told me the last painter whose quality went down hill, masked the walls and sprayed ceilings last. I am going to try this, does anyone mask walls and spray ceilings last? We don't cut in walls, only TU. The walls are 9 to 10 '.
