Each floor surface needs a different approach. Get it right and your floors last longer. Get it wrong and you cause damage you cannot undo.
Not all floors are the same. If you clean a sealed concrete floor the same way you clean glazed ceramic tile, you will eventually ruin one of them. Porcelain tile can handle aggressive scrubbing. Epoxy coatings scratch if you use the wrong brush. Polished concrete needs neutral pH or the sealer degrades.
This guide covers the three most common commercial floor types — tile, concrete, and epoxy — and explains the right way to clean each one. Whether you are using a mop or a floor scrubber, the fundamentals stay the same: use the right chemical, the right pad, and the right technique.
Tile is the most forgiving floor surface to clean. Glazed ceramic and porcelain tile are dense, non-porous, and resistant to most cleaning chemicals. The weak point is the grout — unsealed grout absorbs moisture and stains easily.
The right approach: Use an alkaline or neutral pH cleaner. Tile handles stiff brushes well — polypropylene or nylon brushes at 600-1,000 RPM are effective. Avoid acidic cleaners on grout unless you are intentionally stripping and re-sealing. For regular maintenance, a walk-behind floor scrubber with soft brushes and a neutral cleaner keeps tile clean without damaging grout.
The wrong approach: Using too much water and letting it pool in the grout lines. Excess moisture seeps under the tile and can cause adhesive failure over time. Also: don't use oil-based mop treatments on tile — they leave a film that attracts dirt and makes the floor look dull.
Concrete is durable but porous. Raw concrete absorbs oil, grease, and moisture. Sealed concrete adds a protective layer that makes it much easier to clean — but the sealer itself requires care.
Sealed concrete: Use a neutral pH cleaner (pH 7-8). Alkaline or acidic cleaners break down the sealer over time. A floor scrubber with soft brushes or pads at 800-1,200 RPM works well. According to ISSA cleaning standards, a 28-inch walk-behind scrubber cleans sealed concrete at roughly 10,000-14,000 sq ft per hour — about five times faster than mopping.
Unsealed / raw concrete: More aggressive cleaning is acceptable since there is no sealer to protect. Degreasers and alkaline cleaners work well for oil and grease stains. A scrubber with stiffer polypropylene brushes handles the texture of raw concrete without damage. Unsealed concrete needs more frequent cleaning because dirt embeds in the surface pores.
The wrong approach: Using a high-pressure washer on sealed concrete — it forces water under the sealer and causes delamination. Also, letting oil stains sit for weeks makes them nearly impossible to remove without grinding the surface.
Epoxy is a high-performance coating that creates a seamless, glossy surface. It is common in food processing plants, pharmaceutical facilities, showrooms, and garages. Epoxy looks great and resists chemicals — but it scratches easily.
The right approach: Mild neutral pH cleaner. Soft white or red pads only — no stiff brushes. Low RPM (300-600) for routine cleaning. Use an automatic floor scrubber with pad drivers instead of brush decks. The key is to remove dirt without creating micro-scratches that dull the gloss over time.
The wrong approach: Using highly alkaline cleaners, abrasive pads (black or green), or stiff brushes. These create visible swirl marks in the epoxy that cannot be polished out without re-coating. Also: do not let metal debris sit on epoxy floors — rust particles embed in the coating and leave permanent stains.
When to refinish: Even with perfect care, epoxy dulls after 3-7 years of foot and vehicle traffic. A floor scrubber with a red pad and a burnishing compound can restore the gloss temporarily. When that stops working, it is time to re-coat.
Yes — with the right adjustments. Most walk-behind and ride-on floor scrubbers let you swap brush types and adjust down pressure. Use interchangeable brush decks or pad drivers to switch between surfaces. A facility with tile restrooms, a concrete warehouse, and an epoxy showroom can use one machine with three different pad/brush setups.
TerraScrub's walk-behind models (BA430, BA530, BA730, BA860) and ride-on models (BA850, A17) all support interchangeable brush decks. Donnie can help you pick the right pad and brush combinations for your specific floor types.
Yes, as long as you switch the brush or pad type between surfaces. Use a medium-stiff brush for tile, a soft brush or pad for sealed concrete, and a soft pad for epoxy. Most TerraScrub models support quick-change brush decks that make swapping between surfaces a two-minute job.
Highly alkaline cleaners (pH above 10) will dull and etch epoxy coatings over time. The coating may look fine after one or two cleanings, but repeated exposure creates a hazy appearance and eventually breaks down the resin. Always use a neutral pH cleaner on epoxy.
Sealed concrete typically needs resealing every 2-4 years, depending on traffic levels and cleaning frequency. A simple water test tells you when it is time: splash water on the floor. If it beads up, the sealer is still working. If it absorbs immediately, it is time to reseal.
Machine scrubbing is faster and more consistent. A walk-behind scrubber cleans 8,000-12,000 sq ft per hour on tile, compared to 2,000-3,000 sq ft per hour with a mop. The scrubber also applies consistent pressure across the entire surface, so you do not get the streaks and missed spots that come with manual mopping.
Yes. Unsealed concrete can handle stiffer brushes and more aggressive cleaning. Just be aware that unsealed concrete absorbs moisture, so you need a good squeegee and vacuum system to remove as much water as possible. TerraScrub models come with high-performance squeegees that leave the floor walk-dry after cleaning.
Tile, concrete, and epoxy each have their own cleaning rules. Use the right cleaner pH, the right brush or pad, and the right scrubber speed for each surface. Get that right, and your floors will look better and last longer.
If you are running a facility with multiple floor types, a single floor scrubber with interchangeable brush decks is the most practical solution. Donnie can recommend the right TerraScrub model and the pad/brush kit you need for your specific surfaces.
