I’m helping a friend paint inside walls of the new condos he’s building. I’m the cutter, he’s the roller.
Load it up, brush it out to within about 1/4″ to 1/2″ of the edge you’re cutting to, then reload, position the brush, take a deep breath, keep steady, and start and then bring the cut right onto the edge, then do the drag. Straight, right in there. Gallon after gallon.
For latex, what brush do you find works best for this? A guy let me use his brush once, it was a big one, slash bristle ends, not straight cut, had an oval ferrule, probably held half a quart of paint. It was great. I could cut from full outreach back to in front of my eyes and then halfway over the other side, and still be cutting wet.
I can’t find a brush like that now.
