General cleaning & preventative maintenance

If you’re wondering how to clean concrete in order to keep your surface looking its best, here are some basic maintenance guidelines.

  • Regularly remove accumulated dust and debris so it doesn’t stick to the decorative concrete or act as an abrasive. You can do this with a push broom, dry mop, wet mop, or hose—choose the appropriate tool for the location of the surface. If clean water doesn’t remove the dirt sufficiently, you can use a pressure washer and/or a non-abrasive cleaner.
  • Clean up liquid and chemical spills immediately with a clean, damp cloth so the spill doesn’t damage your decorative concrete.
  • Prevent stains on indoor floors with a commercial-grade floor wax. The wax will preserve your sealer and protect the floor against stains and abrasion.
  • Prevent scuffs and scrapes in high-traffic areas. Use felt pads or sliding casters under furniture or equipment legs to prevent scratching the finish. Place throw rugs, fabric, or rubber mats in areas where you have heavy furniture or equipment. Avoid mats backed with plastic or acrylic, as they may contain plasticizers that will try to bond with your coating or cause discoloration.
  • Refresh your concrete sealer when necessary. The contractor who does your decorative concrete work should be able to tell you how often you need to reseal your surface. (See more about sealers.) It’s important to use proper cleaner to ensure that your sealer doesn’t degrade or turn yellow.

Warnings

In addition to knowing how to clean your surface, it’s important to know what not to do. Here are some common mistakes people make when cleaning that can damage a decorative concrete surface.

  • Do not use cleaners such as ammonia, bleach, as they will slowly eat away at your finish.
  • Do not use hot water. It may leach into your coating and cause whitening. (Warm water is fine.)
  • Do not apply tape to your decorative concrete floor. The adhesive resins will eventually migrate into the finish and could possibly pull the finish and stain off the floor. If you must use tape, use blue painters tape and remove it as soon as possible.

What to do when cleaning doesn’t help

Sometimes a concrete surface reaches a point when it just doesn’t look good anymore—even after it’s been thoroughly cleaned. Maybe it’s endured years of neglect or it’s just old and outdated. No matter the reason, SUNDEK can help.

Concrete resurfacing is a great option for homeowners or business owners who want to make an enhancement without having to demolish their existing concrete. With SUNDEK coatings, our contractors can make an old surface look brand new at a fraction of the cost of tearing everything out and starting from scratch. You’ll get a gorgeous surface without the headache or inconvenience. We can complete resurfacing jobs in just a few days.
