This is the most important step in preserving an acid-stained or decorative concrete floor. Dust mopping regularly prevents sand, dirt and other debris from building up on the surface, abrading the floor finish and wearing through the concrete sealer and stain below it. Dust mopping also removes an estimated 80-90% of indoor dust that serves as air pollutants, health hazards and sources of allergies.
Any light-duty sweeping or vacuuming tool works fine for this purpose, but Premier Veneers - and our colleagues in decorative concrete flooring around the country - finds that an 18” - 36” microfiber dust mop works best. The static electricity created by this flat, broad-surfaced material picks up small debris and contaminants like a magnet. But you need to make sure that the dust mop you choose has not been treated with any oils, silicones or cleaners by the manufacturer, and shake it out periodically so as not to scratch the floor.
Vermont Country Store (VCS) has a great dust mop called the All Cotton Dry Floor Dusting Mitt that is perfect for acid-stained concrete floor maintenance. It's available online for about $54.95 here: Vermont Country Store. You can also get the China Brands Hygen online for $15.37, while supplies last, at Shop Market Express. The new price will be approximately the same as the VCS All Cotton Dry Floor Dusting Mitt above.
If you prefer a vacuum, Euro-Pro has a great new lightweight, vacuum called the Shark Vac-Then-Steam for hard surfaces, including concrete. It's slightly more expensive, at $120 from Overstock.com, but lets you avoid having to shake out a dust mop from time to time, and then allows you to "steam mop" and sanitize after vacuuming.
Note: When using a vacuum only, be more thorough, since dust pickup is generally somewhat less effective and complete than with a dust mop or broom.
