"I decided to make this a DIY project as part of moving into our new home. I did a lot of research on-line before starting and the info sort of made me paranoid since if not done properly you can easily end up with a result that you are not happy with as well as making this a much bigger project than it should be.
Armed with a “healthy paranoia” I decided to overweight the prep as everyone suggests even though my garage floor was brand new cement with no stains. I am not a big fan of the use of muriatic acid so I decided to prep the floor by essentially sanding it. I did this by renting a floor maintainer from Home Depot with a diamond disc which is what Home Depot recommended. It look me about 3 hours (and $75) to sand the entire floor, remove the slick feel, and open the pores of the cement. I then rinsed off as much of the dust as I could with a garden hose and then scrubbed the floor with the cleaner provided in the kit. I then power washed the cement multiple times (3 total) until I could run my finger across it without significant dust getting on it.
I let the cement dry (only took approximately 24 hours) and then applied the epoxy. Went on as expected except that I found that I got much better coverage on my 400 sq ft garage and ended up only using one kit even though I was told a single kit only covers 200-250 sq ft. Admittedly the last part was a little challenging as it does become hard to work with after about 2-1/2 hours but overall it turned out great. One coat seemed to be sufficient and I applied the decorative flakes and put two coats of the acrylic glaze from a one gallon can. Stayed off of it for 72 hours and didn’t drive on it for 96 hours. I am hopeful that with our weather (60-90 degrees year round) that it will last for many years but we’ll see.
Overall I am very satisfied with the product and appreciate the help I received from the local Sherwin Williams store to help ensure a successful result."
