So you’ve decided to get an epoxy flooring for your brewery. Now all you need to do is apply the epoxy flooring properly. While this is a simple task, there are several things that need to be done to guarantee your floor comes out just the way you envisioned it.
Before Applying Epoxy
The absolute first step before applying your epoxy coating, is to prep your floor. It is essential that you clean your floor thoroughly. If you’re working on a concrete base, fill in any cracks or patch areas that need care before you start to clean. Once the damages, if any, have been repaired, it’s time to clean. Be sure to catch any areas you might overlook while preparing your epoxy coat. Oil spots will need to be removed and the floor will need to be degreased. Your floor is cleaned properly and you will want to make sure you vacuum thoroughly to rid of any remaining dust and debris.
The biggest problem you will encounter when applying your epoxy coating, is to make sure the moisture and humidity are in the right conditions. Conducting a moisture test on your concrete base is a reliable way to make sure the epoxy flooring will be applied properly. This can be done cheaply and effectively by taping shut a plastic sheet to your floor. After a day or so, you’ll notice if moisture has appeared or gathered underneath the plastic surface. If it has, you will need to apply a moisture blocking sealer. This is due to the fact that epoxy can be impossible to work with in high moisture conditions and will not guarantee a sealed floored. If the floor is not sealed properly then epoxy may not adhere causing the floor to bubble.
There are three main methods for preparing your floor for epoxy work, so take your pick on which one will best suit your needs.
1. Acid Etching
The first is acid etching. This technique is the most D.I.Y. option, as other techniques require machinery or skill. And is best used for concrete bases. First you need to apply the acid solution to your floor. Once it is spread out evenly use a scrubber, a stiff bristle broom, or a similar tool to work the acid solution. Once that it’s done, let the acid sit for up to 10 minutes, this will allow the process to take effect. Next you have to remove the spent acid. This can be done through power washing and then vacuuming once the floor has dried. Make sure to remove the residue before the acid dries. Finally you’ll need to neutralize any remaining acid residue. Using a diluted solution of simple green will work well on most floors (approximately 4oz per gallon of water)
2. Diamond Grinding
The second method for preparing your floor is diamond grinding. This method will restore smoothness to your floor, which is needed prior to an epoxy coating. The diamond grinding method requires the use of machinery, however, it is quite easy to do. You will need a floor grinder with the proper attachments for your floor. Once the machine is turned on, use a side-by-side swaying motion to smooth out the entire surface of your floor. After this is complete, vacuum heavily to clear away any residue left behind. Be sure to always keep the grinder in motion to avoid grinding circular rings and low spots into the floor.
3. Shot Blasting
The final method that can be used to prepare your floor is shot blasting. There are various styles for this technique but all require machinery to flatten out a surface. Some people prefer diamond grinding to this method, but both will get the job done. The machine will pelt tiny metallic beads into the floor to blast away any stains or damages to the base. The advantage of this, as opposed to diamond grinding and acid etching, is that there will most likely not be any residue left over, as the machine captures everything. This technique requires a some skill and should be used on larger scale jobs.
