The previous owners of my house laid tiles over the concrete floor in the garage (i don't think they parked their car in it). These are old tiles with a thin adhesive – not like the white caustic adhesive you'd use with ceramic or stone tiles.
So, I want to remove the tiles and put down garage concrete floor epoxy. What do I need to do to prep the floor for good adhesion? And what if I can't get all the old adhesive up?

The adhesive used was a latex based adhesive.After removing the tiles you will need to use a solvent like mineral spirits, turpentine or thin bodied paint stripper (this works the best and it is water soluble).All of these items have a strong odor so close the door to the house if the garage is attached and be sure you have enough ventilation in the area.You may have to let the solvent set on the glue until it softens. Section the garage floor in 4 parts. Using a scraper hand held or mounted on a pole ,work on 1 part at a time until you have removed 85 to 90 % of the adhesive. Once you have completed the entire floor then rent a floor buffer and purchase the most aggressive scrub pads available (usually the black ones). Use a industrial strength cleaner such as "TSP" or the equivalent. Mix a solution of 1/2 cup cleaner to a gallon of hot water and apply to the floor a small area at a time until the remains of the solvent and adhesive can be mopped up or squeegeed in to a drain. This is not the easiest task but for epoxy paint you need to have the surface as clean as possible or it will not adhere properly. Once your clean up is complete rinse the floor with clear water and let it dry over night. Follow the directions for applying that are on the label of the epoxy paint can and you should be fine. Just for information there are several good latex paints which work well and are bit more forgiving than epoxy for this use. Look into all available options before purchasing the paint. The prep work will remain the same.Good Luck

    There are adhesive removers in the paint department at your local hardware store. Also, there are concrete prep solutions in the same section. Use that or Muratec acid (be careful with this stuff though), because you need to etch the surface for maximum adhesion of epoxy.

    Listen to Veritas, plus the floor should be warm, ambient temperature should be no less than 70 Degrees. or the finish will have an orange peal look to the finish.

    Have finished two very large shop floors,and one was done in a very cool temperature, and had a orange peal look to it.

    I highly recommend using GG ULTRA SEAL to seal your floor. It will outperform the competition time after time. Another benefit to our product is its ability to penetrate through previously sealed substrates when mixed with acetone or lacquer thinner.

    This is a huge benefit and will allow you to change an existing colored floor by simply spraying our product over the top. Once applied, it automatically penetrates through the sealer. Once it is dry, the sealer is once again intact (assuming the previous sealer was in good shape to begin with) and you are finished. This product is truly unique and is changing the market. Ease of application and outstanding pricing, make this product the easiest choice you will ever have to make. Not only will you save money with our pricing, but you will also save valuable time which turns into more savings in your pocket!

    1) Storage concerns.
    2) Drying time.
    3) Having the right tools.
    4) The right amount of stains and sealer.
    5) Monitor the progress.
