Concrete Floor Coatings

Concrete coatings are alwagarage-floor-micro-toppingsys known to and improve the appearance and extend the life of your decorative concrete surface. It usually comes at low cost and is a great way to make a large improvement on your old and drab concrete area.

If you want to go for a concrete contractor who can do a quality coat, then it’s always good to ask us here at Bullion Coatings what preparation method should be used. But if you’re more of a do-it-yourself person, the number one question that’s probably running in your mind right now is about the proper and best method that would work best for your concrete surface; or maybe there is a specific style of coating that you like. For example, a stamped overlay system can be applied to imitate the certain kinds of boulders, bricks or pavers, and basically any other kind of surface.

Whatever the case may be concrete surface.

Common Types of Concrete Coatings

  • Thin film coatings (thickness ranging from 5 – 20 millimeters)
  • Thick film coatings (coatings with thickness ranging from 20 – 120 millimeters)
  • Aggregate-filled toppings, (thickness range of 120 – 250 millimeters)
  • Micro toppings

After you’ve figured out the type of coating that you would like to use, it’s now time to figure what kind of concrete coating preparation you will use. The main goal of preparing your surface is to remove unnecessary surface elements such as oils, grease, chemicals, curing compounds, and any other kind of contaminants that are present in the concrete surface. Here are some of the common preparation methods that we use and the circumstances where they work best.

Diamond Grinding

To achieve this, a machine with a cupwheel is held flat to the surface that’s for grinding. You can use any of a variety of handheld machines, or even the big ones that are large enough for you to walk behind. This process is slow but environment-friendly, leaving a very smooth surface after. This system works best for thin and thick film coatings and micro toppings.

Shot Blasting

This process involves using a gun to shoot the concrete surface with steel balls at a very high velocity (kind of like a shotgun on a surface). By using this, it removes the softest (and oldest) concrete layer which prepares the underlying surface for a stronger bond. Shot blasting works best for aggregate-filled toppings

Acid Etching

This one is usually used to prepare the surface of home shops, garages, basements and general concrete. Acid etching works best on thin film coatings and micro toppings.

Scarification

Most often used in road constructions, it’s probably the most violent out of these three. To do this method, steel or carbide star-shaped cutters are mounted in several rows around a rotating drum. This works for best for the aggregate-filled topping and micro toppings as well.
