Most of the above answers are correct. I would combine a few to make sure it lasts. You do not have to use a two part epoxy anymore. There are garage floor paints and stains on the market that work great. Go to your local Benjamin Moore or Sherwin Williams paint store and they will show you your options. Here are the proven steps to a correctly done garage floor:


1. Sweep and clean the floor with a strong degreaser. Any oil or grease like substance on the floor will work like a barrier for the bonding agents of the epoxy. (not TSP, since they took out the phosphate, it's just trisodium)


2. No need to power wash unless you have one handy. The real trick to longevity of the epoxy is opening the pours of the concrete with muratic acid/water mix . I usually wash it once, rinse, then wash it again with the acid/water mix to make sure the product will adhere. Just don't use too concentrated a mixture of acid to water or it may leave poc marks. This stuff is strong so wear rubber gloves and a respirator.


3. Let dry well, using fans if possible. Concrete can be like a sponge and the water needs to escape before you seal it. This is a very important step.


4. Seal cracks with a concrete floor crack filler. These are the spots the floor will start to peel from since it is a place moisture can push up through the epoxy. Tip: Where ever the crack filler is will appear shinier than the rest of the floor, so try to fill just the cracks.


5. Apply your cemente epoxy as reccomended by the manufacturer. As suggested, I always allow an extra day or two dry time. After all this work you do not want to scar and ruin the appearance just because you got impatent.





Note: Car tires are very hot after driving. When you pull in and let them sit, they cool down and can lift the epoxy underneath. I strongly recommend putting down a barrier for just the tires to sit on like four squares of carpet or rubber mats.I want to paint my garage floor,is 30 yrs old, has never been painted. any good info out there?
First, if you are going to paint it or use epoxy i would recommend renting a pressure washer from your local tool rental company. Spray a degreaser on the floor to remove any grease or oil. This will insure that whatever u coat the floor with will bond well with the concrete. Second, patch any cracks in the floor with a vinyl concrete patching compound. Third, whether you paint or epoxy be sure to make sure it has a skid resistant additive in it (sand). Most of these paints and coatings can be bought with the skid resistant additive already in it. If you cant find a coating with it already in it, you can buy the additive and mix it in yourself per directions on package. After you have the coating on the floor i would recommend giving it and extra 3 days of drying time past the manufacturers recommendation before driving vehicles on itl
I have done a lot of concrete work being a construction worker. What I find to work the best is to first sweep the floor, power wash it, clean again with a muratic acid/water mixture (50/50 depending on how much cleaning it needs), rinse the floor, after drying well, get a good epoxy bond sealer (applies just like paint). You should be able to get a good sealer at any Lowes, Home Depot, or any place like that.
You can clean it well with muratic acid and then apply Drylock brand cement sealer.
Go to a good paint store like Sherwin Williams or Benjamin Moore and ask for advice.
