When a mop can no longer cut through built-up soil, the Mercury 1502 scrub brush turns your rotary floor machine into a serious hard-floor scrubbing tool. Built for janitorial crews, facility maintenance teams, and building service contractors, this 13-inch brush block seats onto a standard 175 RPM single-disc floor machine and drives stiff natural bristles across the surface to lift ground-in dirt, break down old cleaner residue, and prep floors for stripping or recoating. If your green pads are glazing over on textured or heavily soiled floors, a bristle brush like the 1502 reaches into the low spots a flat pad simply rides over.
Built for
- General wet scrubbing of hard floors such as VCT, sealed concrete, quarry tile, and terrazzo with a machine-friendly detergent solution.
- Deep-cleaning textured and grouted surfaces where coarse bristles flex into grout lines and surface texture that a pad cannot reach.
- Strip-prep scrubbing to agitate and loosen tired floor finish and heavy soil load before a full strip-and-recoat.
- Warehouse, shop, and back-of-house concrete that sees foot traffic, tire marks, and machinery grime.
- Restroom and entryway floors where repeated soil buildup resists routine pad cleaning.

Frequently asked questions
What machines does the Mercury 1502 fit?
It is built for standard 15-inch commercial rotary floor machines that run at about 175 RPM and use a Mercury Type B / 92 clutch plate with a 5-inch center hole. That clutch plate style fits a wide range of common floor machine brands, so confirm your machine takes a B / 92 plate before ordering.
Should I use a brush or a pad?
Use a bristle brush like the 1502 when floors are textured, grouted, or heavily soiled and a flat pad cannot reach into the low spots. Pads are better for smooth, glossy finishes; bristles get down into surface texture and grout lines for a deeper scrub.
What is Bassine and why is it used?
Bassine is a natural, coarse plant fiber commonly used for general-purpose floor scrubbing. It holds water well and provides firm scrubbing action, making it a practical choice for routine hard-floor cleaning and strip prep.
Can I strip floors with this brush?
The 1502 is a scrub brush, so it excels at agitating and loosening soil and worn finish as part of strip prep. For an aggressive full strip you would typically pair the machine with dedicated stripping pads and stripper solution; the brush helps break up buildup on textured floors where pads struggle.
How do I care for a new bassine brush?
Because bassine is a natural fiber, many crews soak the bristles in cool water before first use and let them hang to keep the fibers from drying and cracking. Rinse the brush after each job and store it off the bristles so they keep their shape.
