This is a short 4 second clip I shot on a repaint cutting-in a casing with the Wooster Alpha paint brush. Be sure to check out the brush review for more info on the Wooster Alpha brush. For this video I used the 2½” or 65mm angular brush.
One thing worth mentioning is the brushes ability to accurately maintain a solid wet edge for a great distance effortlessly without repositioning the brush. Although the video only shows a distance of 3½ feet (half a casing), my brush had enough paint to keep going.
In the video, watch the distance between the right side edge of my cut and the tape measure (white space). The brush stays solid on both edges but only the right side was loaded with paint. I was spreading 100% acrylic low sheen eggshell wall paint. It may help if you set your video player to loop or repeat due to its short length.
