👷⚙️ Staircase Plaster Finishing: Hand Trowel Smooths Concrete Stringer

▶ Watch in the Shorts feed

Finishing a staircase stringer with joint compound begins as the mason loads white plaster onto a stainless steel finishing trowel. The worker reaches upward and sweeps the smooth metal blade along the exposed concrete edge under the stair steps. Controlled upward and downward strokes press the compound evenly onto the rough wall surface, concealing gaps and joint seams. The fluid troweling motion produces immediate seamless coverage, creating a sharp, crisp angle along the staircase skirt. As Swipe or use ↑ ↓ to keep watching.
