What it does
18" MAXXGRIP PRO knockdown knife with a flexible, clear polycarbonate blade and an aluminum bridge. The soft-grip handle is Acme-threaded for extension poles. It flattens texture sprayed by a hopper gun and applies nothing itself.
How to use it
- Wait until the sheen falls off the texture. Test a corner blob. If it smears, wait. If it flattens clean, knock down.
- Hold the soft grip with a loose wrist. Let the blade's flex set the pressure.
- Wipe the edge clean every pass or two.

Common questions
Is the blade acrylic or polycarbonate?
Polycarbonate. Hyde's video names it LEXAN. The store title's acrylic is loose wording.
18 or 24 inches?
18 for walls, rooms, repairs, perimeters and a first knife. 24 for open ceilings with the fewest laps.
Do I need the hopper gun?
Yes. This knife only flattens what a gun, such as the 09980, sprays.
Can I remove popcorn ceiling with it?
No. Hyde bars it. Popcorn ceilings from before 1980 may contain asbestos and must be tested first.
