Honestly, using a skimming blade isn't rocket science - but there's definitely a bit of a rhythm to it. The first time I picked one up, I went too fast and left streaks everywhere. Once I slowed down and let the blade do the work, it clicked.
Here's how it goes: after you've applied plaster or joint compound with your trowel, you take your skimming blade and pull it across the wall in long, smooth strokes. Keep it at a slight angle - not flat, not too steep - just enough so it glides without scraping too much off.
The trick is light pressure. The blade's flexibility does the work for you, flattening the plaster evenly while leaving a fine layer behind. It's super satisfying when you get that buttery-smooth glide.
You'll probably need to go over the wall a few times as the plaster firms up. Just clean your blade often - dried bits on the edge will leave lines. I always keep a damp cloth handy for quick wipes.
And if you're wondering which tool to trust, I've had great results with Hanke Tools skimming blades. They've got a solid handle, smooth stainless steel, and they stay comfortable even after a long day's work.
Once you get used to it, you'll never want to finish a wall without one.
