Frequently asked questions

What is a union-mix brush and when should I use it?

Union mix is an economical blend of natural fibers, typically Palmyra and White Tampico. It is softer than a stiff bassine or nylon scrub brush, which makes it ideal for general-purpose polishing and light scrubbing on finished floors rather than aggressive stripping.

What size machine does the Mercury 1301 fit?

It is designed for standard 13-inch rotary floor machines. The 11-inch brush block spreads its bristles out to about 13 inches of cleaning coverage, following the common rule that a brush block runs about 2 inches smaller than the machine size.

Will this brush fit my floor buffer if it is not a Mercury?

The included Mercury Type B / 92 clutch plate has a standard 5-inch center hole that fits many brands, including Kent, Pullman Holt, Oreck, Advance, Clarke, Betco, Eureka, Hawk, NSS, Nilfisk, Tornado, and Viper. If you are unsure, check your machine size, make, and model before ordering.

Can I use it to strip old floor finish?

No. Union-mix natural fiber is meant for polishing, buffing, and light scrubbing. For stripping and heavy wet scrubbing you want a more aggressive nylon or grit brush. Also do not use this brush with flammable materials such as fuels, solvents, or thinners.

Is the clutch plate included?

Yes. The 1301 comes with the Mercury Type B / 92 clutch plate that attaches the brush block to the machine, so it is ready to mount on a compatible 13-inch buffer.
