Cut-In and Back-Roll Corners

What happens here

When cutting into corners, follow a similar procedure. Using your loaded 2.5-inch angled sash brush, drag the paint line vertically up the corner, extending about 3 to 4 feet. As with the ceiling cut-in, drag the brush in one direction, then reload, and drag it back in the opposite direction over the same section to fill in texture. Immediately back-roll this section with the 4-inch mini-roller to blend the paint and texture. Perform all corner cut-ins before rolling the main wall sections to prevent the appearance of 'halo-ing,' where a visible outline of the brushed area can appear if rolled paint dries before the cut-in is applied.

Goal: Create clean, blended paint lines in internal corners.
