Everybody keeps saying junk,low end. What's low end about it the cost? Thickness, durability? Have you used the product? Go on amazon.com and read the reviews.
It's not the most expensive if thats your gage..
I don't think you read the article. There is a reason it costs less. One of these reasons is that most of these kits are only a little over 20% solids by weight. That means 80% of the initial film thickness when put down is going to evaporate once it cures. What you end up with is a coating that is only 3 to 4 mils thick and it referred to many times as paint. Using Rustoleum as an example, their 100% solids epoxy is 16 mils thick. When applied to a properly prepared floor, there is no comparison between the two in terms of durability and wear. And we are only comparing 1 coat. What if there were two?
That said, there is a market for the $69 epoxy paint kits. That's why they sell so well. They do OK for the average homeowner who has a low traffic garage floor and wants something down that is easy to clean, will resist stains, and looks good. Plus, they are easy to apply and have a much longer pot life than 100% solids. Will they last a long time? No, maybe 4 to 5 years depending on the circumstances. Some will peel in spots within a year from hot tire pickup. Many don't last more than a year because of poor prep. If you dig around a little you will find many unhappy people who use these. If your floor was prepped well and you spring for the optional clear top coat you might stretch it out a little farther and get a nice shine to go along with it.
That is why some people refer to these kits as junk. However, if you are on a tight budget and want something to put down that will last longer than paint, they are an attractive alternative for the price.
