Pour in enough paint so that it almost fills the well toward the bottom of the tray without covering the angled portion of
the tray where the ridges are. For a pail, pour in about 2”. You are now ready to paint by loading the brush. Hold your
brush with a pencil grip, with the longer side of the brush bristles in line with your pointer finger. Dip the brush into the
paint, but be careful not to load more than 1/3 the length of the bristles with paint. Gently tap the brush against the side
of the bucket to remove any excess. Tapping the brush, rather than wiping it on the edge of the pail, keeps the brush loaded with paint without dripping.
Dip your roller into the paint tray, rolling it back and forth across the tray’s ridges a few times to remove any excess and prevent drips. Make sure the roller gets evenly coated. For the first time you roll after rinsing the roller, you may have some extra water in this first application. Just keep rolling and go back over the area with a finishing roll as noted below.
Run the roller up and down a section of the wall, applying paint in a “W” pattern.
Fill in the “W” pattern until your section is fully coated. Complete the section by doing a finish roll in one direction from top to bottom across the entire section. Refill the roller as needed.
Keep a wet edge when moving from each section rolling over your cut in while they’re still wet, getting as close to the edge with the roller for a uniform finish.
