January 14, 2023

You’ve made the decision to install epoxy flooring in your brewery. You now need to apply epoxy flooring correctly. Although this may seem like a straightforward task, there are many things you need to do to ensure your floor looks exactly how you imagined it.

Before applying epoxy

Preparing your floor is the most important step before you apply your epoxy coating. You must thoroughly clean your floor. You should fill in any cracks and patch areas if you are working with concrete. It’s time for cleaning once the damage has been repaired. When preparing the epoxy coat, make sure you catch any potential problems. The floor will need degreased and oil spots must be removed. You have cleaned your floor properly. To get rid of all dust and debris, vacuum well.


There’s three main ways to prepare your floor for epoxy. Take your pick!

Acid Etching

Acid etching is the first. This is the easiest DIY technique. This technique is the most DIY-friendly, while other techniques require skill or machinery. This is the best option for concrete bases. Apply the acid solution to your flooring first. Spread the acid solution evenly using a scrubber or stiff bristle brush broom. After the acid has been applied, allow it to sit for at least 10 minutes. This will allow the process of absorbing the acid to work. The next step is to clean up the acid. After the floor is dry, you can power wash it and vacuum it. Be sure to get rid of any residues before the acid dries. You will need to neutralize any acid residue. A diluted solution with simple green (approximately 4oz per gallons of water) will work well for most floors.

Diamond Grinding

Diamond grinding is the second method of preparing your floor. This will give your floor a smooth finish, which is important before applying epoxy. Although the diamond grinding process requires machinery, it is very simple to perform. A floor grinder that has the appropriate attachments is required for your floor will be needed. After the machine has been turned on, you can smoothen the entire floor surface with a side-by’side swaying motion. Once the floor is smooth, vacuum well to remove any remaining residue. To avoid grinding low spots and circular rings into the floor, keep the grinder moving.

Shot Blasting

Shot blasting is the final option for preparing your floor. Although there are many methods for shot blasting, all require the use of machinery to smoothen the surface. While some prefer diamond grinding, both methods will work. To remove any stains or damage to the base, the machine will blast tiny metallic beads into your floor. This is a better option than acid etching and diamond grinding. The machine will capture everything, so there won’t be any residue. This technique is best used for larger jobs that require a lot of skill. Preparing the floor is key to smooth, even results. Make sure you research the method before making your decision.
