OK, the process is finally done on our 2 1/2 plus 1 garage and we love the outcome. It came out great and I want to tell you the full story. Yes, using this product you will save a lot of money versus calling a professional and yes, it is easy to apply with caveats that I will spell out for you and yes the kit does cover 2 1/2 standard garages. First, do not believe that you can apply this and be back in your garage in 3 days; second, it comes out better with the clear over coat; third, make sure you watch some YouTube videos on the process so you know what to expect. Now for the details:1) You must clean your garage floor thoroughly before application. The etch product is included with the kit however if your floor is oily, greasy, painted, or otherwise stained, you will need additional products to clean it first. My garage floor was new so not stained however the builder did spill something on the floor that water beaded on so I knew I had to strip that prior to application. The epoxy actually bonds with the concrete so anything that prevents bonding will cause the finish to peel later. Clean, clean, and clean again! I pressure washed first, used the provided etching, then bought additional products as necessary and repeated the process until I was satisfied the floor was clean. You will need a squeegee and a stiff floor broom for this process.2) After cleaning, wait 3 days for the floor to dry thoroughly, longer if it is very humid or you live in a damp area. If it is not dry, the epoxy will not bond with the concrete. The instructions say to tape a 2 x 2 piece of plastic to the floor for 3 days to test for moisture; DON'T DO THIS! I did it the first time and the adhesive from the tape left a residue that I then had to remove and reclean the floor again! The 3 day clock restarted. To help the drying process I ran a floor fan 24 hours a day for the 3 days which helped a lot.3) Once the floor is dry, you can start the painting process. Pay attention to the instructions on painting time and temperature as this affects how long you can work with the paint. Only walk on the cleaned floor with clean shoes or socks to avoid any contamination. Use your blower to ensure there is no dust, dirt or bugs on the floor prior to painting. Mix the product as directed but I found that the color was consistent and did not need to mix the base paints first. Also, mixing is a PITA and very messy, losing precious paint. If you are painting the foundation walls too like I did, start here. This is tedious work and takes time so have help. Remember, once the epoxy is mixed in the paint, you are on the clock before the product becomes unusable (called pot time). It took us the full 2 hours to paint the 12" foundation walls, cut in along the wall/floor joint, and paint the floor which stretched the limit. Use a 12" or 14" roller if you can. I believe the instructions say paint in 4' x 4' sections but I found it easier to add the color chips, if you are using them, by painting a 2' x 8' section (it is easier to spred the color chips this way). Clean up tools with soap and water.4) Color chips; we wanted more color than the base gray so we went very heavy on the chips. We actually bought 2 extra bags of chips for the 2 1/2 car garage (4 total bags used) and used both bags from the kit for the single car garage. After 3 days of drying, we used a shop vacuum to knock off any loose color chips before we used the clear coating sealer.5) At this point elapsed time is a minimum of 7 days (unless you have to reclean like I did) and if you apply the clear sealer, which I highly recommend, it takes another 3 days of drying.So my floors look great and make the garage pop; only time will tell if it lasts.
