Graco 18C685 ProSurface Smoothing Blade, 18 in — What It Fits, Where It’s Used & How to Choose

The Graco 18C685 is an 18-inch ProSurface smoothing blade built to deliver fast, glass-like drywall and plaster finishes with minimal sanding. Its INOX stainless, Bi-Flex blade keeps more compound on the wall for efficient wipe-downs and even wear, while rounded edges help prevent lines and material build-up.

Where it’s used

• Drywall/plaster finishing: skim coating, wipe-down after taping, and feathering seams or butt joints
• Residential remodels, new construction, and commercial interiors requiring a paint-ready surface

What it fits

Mounts to the ProSurface handle and works with extendable poles for added reach—20–40 in (18C678) or 40–80 in (18C679). It’s also one of the standard blade sizes included in the ProSurface drywall kit (18C676), making it easy to standardize your setup.

Key features

• INOX stainless, Bi-Flex blade technology for a superior finish and even blade wear
• Rounded edge profile to minimize edge lines and rework
• Ergonomic control with handle/pole compatibility for smooth, low-fatigue passes

How to confirm it’s the right part

1. Match the part number: 18C685 (18 in smoothing blade).
2. Select width by task: 18 in is ideal for medium to wide runs; step down to 10/14 in for tighter areas and up to 24 in for large open walls.
3. Verify compatibility with your ProSurface handle and extension pole before ordering.
