There are dozens of ways to treat a concrete floor. Each has its pros and cons, and choosing one that’s best for your needs depends on understanding what each method entails. We’ve put together a guide to the six most common preparation methods and machines to help you to better understand the benefits of each.
Method #1 – Shot Blasting
Remove the coating, and clean and profile a surface in one step with shot blasting. This dust free, low risk process can remove dirt, paint, contaminants, and coatings, by shooting tiny steel particles at a surface, which then bounce back for recycling, while the removed elements are gathered and discarded.
Method #2 – Grinding
Grinding is the perfect choice for treating large floor areas or providing a very smooth finish, and can level uneven spots and joints. Grinding involves using rotating discs made from unrefined diamonds that move in a horizontal pattern.
Method #3 – Scabbling
Scabbling uses compressed air to force piston mounted bits onto a surface, removing up to 0.5mm of coating in one session. It’s best reserved for extreme damage repair and removal, and is normally followed by a smoothing method to even out any roughness.
Method #4 – Chisel Scraping
When you need to remove tiles, roofing shingles, parquet flooring, or carpets, then you need a chisel scraper. Scrapers are available in hand held air powered machines, which are used to remove grouting, asphalt or fibreglass, or as an engine powered machine to handle larger surfaces.
Method #5 – Scarifying
Complete several jobs with one machine using a scarifying machine. It uses a cutting wheel with removable cutting assemblies, which, depending on the cutter, means that you can clean a surface, level it, remove from it, or even create shallow and evenly spaced grooves.
Method #5 – Acid Wash
Acid washing can remove loosely bonded materials, and doesn’t remove contaminants. The acid wash can only be used on oil-free concrete surfaces, and never on overhead or vertical surfaces. For an acid wash to be effective, a mild acid solution is applied to a floor, and treated with a high-pressure wash. The area is then vacuumed, dried and neutralised.
