Blow Out Cracks Before the Open Surface
Clearing paver joints and cracks with a leaf blower before the open surface, so cleared debris has nowhere left to blow back into.
Blow Debris Away From Walls and Garage Doors With an Upward Backdraft
Technique: Leaf-Blower Backdraft
The Problem
Debris piled against a wall, a doorway, or a garage door is the worst spot for a leaf blower. Aim straight at the pile and the air has nowhere to go: it blasts leaves and grit into the door gaps, under the garage door's bottom seal, into brick cracks — and back into your face. Even a garage with new rubber gaskets around the door ends up with a layer of dirt inside after a straight-on blowing session.
The Technique
Use the wall itself to move the debris.
- Stand facing the wall and point the blower up the wall, a foot or two above the debris.
- The airstream deflects off the wall and rolls back toward you at ground level — a backdraft that pushes the debris out and away from the wall.
- Once the pile has moved out a few feet, step in behind it and blow it away from the building as usual.
Nothing goes into the cracks, nothing comes back at your face, and the debris ends up in open ground where the blower can do its normal work.
Pro tip: This matters most at garage doors. The bottom seal sits directly on the slab, and a straight-on blast packs grit under it and into the garage — the backdraft pass is what keeps the slab inside the door clean.
Safety note: Blowing against a wall throws debris back toward you by design. Wear safety glasses — grit coming off a wall at blower speed finds eyes reliably.
