Why coat concrete?

02 Nov 2022 by Real World Epoxies Pty Ltd

Concrete coatings come in many forms: thin roll-coat coatings, thick trowel-down coatings, self-level coatings, clear coatings, pigmented coatings etc.

With such a great variety of concrete coatings available, they’re naturally used to perform a whole host of roles. Protection, decoration and non-slip are well-known functions that attract most of the attention, however there are a few more reasons why concrete coatings get used that aren’t as widely known.

Our top concrete coating tips below talk about three extremely valuable uses for concrete coatings that perhaps don’t get as much recognition.

Why should concrete be coated?

  1. Concrete dust-proofing - The reasons why concrete floors dust vary with age. For new concrete, the biggest source is a fine, loose by-product of the hardening process called laitance; for older slabs, abrasive traffic is the main problem.

    The problem with concrete dust is how fine it is and, therefore, its uncanny ability to get everywhere! It can contaminate and damage all sorts of valuable things: food, stock, electrical gear...the list goes on. It’s also quite tricky to clean up and very abrasive, which may cause trouble in other sensitive areas, including human lungs for example. With consequences like these you can see why concrete dust-proofing is another big user of concrete floor coatings.

  2. Easier to clean - Left in its natural, open state, a concrete floor acts pretty much like a giant sponge; whatever spills onto the surface will quickly absorb into the slab and be very tricky to remove. This characteristic is bad news on a couple of levels.

    Firstly, the “one-two” punch of rapid staining and stubborn removal is a blow to your hopes of maintaining a pristine concrete floor. Everyone’s seen the dark, dingy garage with oil stains, however the scary part is that it doesn’t need black gunk to look bad. Just about any liquid will soak into concrete flooring and create a colour difference that’s hard to ignore.

    Secondly, by trapping all sorts of grime and moisture, concrete pores provide the perfect breeding ground for bacteria and mould (think shower bases). This can be a health concern for anyone exposed long enough and clearly unacceptable for food processing facilities, hospitals and the like.

  3. Safety and comfort - With the help of concrete coatings, a floor can play an active role in making life easier and safer. The most common example is non-slip coatings, however concrete floor coatings can also improve safety by enhancing visibility and communicating instructions to workers. Bright line marking and colour coding clearly defining steps, thoroughfares and danger zones are universal features on workshop floors for that very purpose. The visibility benefits also extend to the quick detection of spills and other slip hazards. A spill partially soaked up by dirty, dull concrete flooring will be much harder to deal with than one sitting on top of an impermeable, easy-to-clean surface.

    It may come as a surprise to some to hear comfort thrown into this mix as well, however it’s a very real thing. Ask any factory worker who’s on their feet all day in the middle of winter and they’ll tell you concrete coatings can make a big difference to the draught chill factor. They’ll also probably tell you that putting down a pigmented concrete coating, even a plain colour, brightens a workplace considerably.
