How to Clean Your Coated Floor

Routine Cleaning — Day to Day

Sweeping and dust mopping

The single most effective maintenance habit is regular sweeping. Fine grit — sand, concrete dust, dirt tracked in from outside — sits on the surface and gets ground into the topcoat under foot traffic and tire contact. A weekly sweep or dust mop removes it before it can cause wear.

Mopping

For routine wet cleaning, a diluted pH-neutral cleaner and a mop is all you need. Good options:

• Simple Green — diluted 1:10 with water
• Zep Neutral pH Floor Cleaner — used at label dilution
• Mild dish soap — a few drops per gallon of warm water
• Plain water — sufficient for light cleaning

What to Avoid

Polyurea is resistant to a wide range of chemicals, but a few things can dull or damage the topcoat over time:

Handling Spills

Oil and gasoline

Polyurea is oil-resistant, but prompt cleanup is still the best practice. Blot or absorb the spill with rags or kitty litter, then wipe the area with a diluted degreaser and rinse with water. Most oil spills wipe up easily from a coated surface — the coating's resistance is what makes this possible.

Road salt and winter grime

In Wisconsin and other northern climates, road salt is the most common contaminant. Salt brine tracked in from vehicles accumulates near the garage door and can leave a white haze if allowed to sit and dry repeatedly. Rinsing the floor — especially the first 6–8 feet from the door — once or twice per week during winter prevents this buildup.

A pressure washer works well for winter cleaning. Standard residential pressure washers (1,500–2,500 PSI) are safe on polyurea. Use a fan-tip nozzle and keep it moving — don't hold a pinpoint stream on one spot.

Antifreeze and brake fluid

Antifreeze (ethylene glycol) wipes up easily and doesn't harm polyurea. Clean it promptly — it's toxic to pets. Brake fluid is more aggressive and should be absorbed immediately and cleaned with a mild degreaser and thorough rinse.

Paint, stain, and adhesives

Dried paint or adhesive that bonds to the floor surface can usually be carefully scraped with a plastic scraper. Avoid metal scrapers, which can scratch the topcoat. For very stubborn residue, a small amount of denatured alcohol on a rag, applied briefly and rinsed immediately, can help without damaging the coating.

Seasonal Maintenance

Spring

After winter, do a thorough wet cleaning of the entire floor to remove accumulated salt residue, sand, and grime. A diluted degreaser mopped and rinsed works well. This is also a good time to visually inspect the surface for any chips, scratches, or edge areas that need attention.

Summer (especially Texas and southern climates)

High temperatures can make the floor warm to the touch but don't affect the coating's integrity. If vehicles sit for extended periods and you notice any stickiness or marking from tire contact, move vehicles periodically and ensure the floor is clean before parking. Parkay or rubber-backed floor mats left in place for weeks can sometimes trap moisture — allow air circulation.

Fall

A good cleaning before winter sets in is worthwhile. Remove leaves, yard debris, and any organic material before it can stain or trap moisture against the surface. Check any floor drains or channel drains at the garage door threshold — clear debris so salt water can drain freely during winter.

Long-Term Care

How long will the floor look new?

With regular sweeping and occasional mopping, a Penntek polyurea floor maintains its appearance for many years. The decorative flake is embedded in the coating — it doesn't fade or wear away with normal use. The topcoat gloss can gradually diminish in very high-traffic areas (like directly under where tires track in repeatedly) over a decade of heavy use.

Can the topcoat be refreshed?

Yes — if the topcoat shows significant wear after many years, a maintenance topcoat can be applied over the existing system in most cases. This is far less disruptive and expensive than a full re-installation and restores the fresh appearance. Contact us to assess whether a maintenance coat is appropriate for your floor.

What about rubber mats and garage items?

Rubber-backed mats are generally fine for short periods but can trap moisture if left in place for weeks. Use mats with drainage holes or lift and clean under them seasonally. Avoid leaving chemical containers, wet cardboard, or heavy rubber items on the floor for extended periods without periodically moving them.
