HOW TO INSTALL GARAGE FLOORS FROM A TO Z

THE BOOK ON GARAGE FLOORS
All professional garage floor coatings are made of plastic. The word plastic is a noun that describes a synthetic material made from organic polymers such as PVC, urethane, acrilyc, nylon, epoxy, etc that can be easily molded by hand and also sets rigid or slightly elastic.
Plastics are polymers and polymer simply means "many parts". The word polymer comes from the two different words poly (which means many) and mer (which means parts). When you mix two part coatings together you are mixing Part A (monomer) and Part B (monomer) into a bucket to form a wet polymer (many parts). The word monomer means one part. While the polymer is still wet it is not yet a plastic because it has not been molded into place yet. The moment in time that the wet polymer morphs into a solid is called the flash because that moment happens at the speed of light. The amount of time it takes for a coating to dry after it has been mixed is called the flash time. There are thinners that you can put into coatings to extend the flash time so that the coating does not dry so quickly which is why thinners are also called retarders, because they slow down the nature of the process (drying.) Adding solvents to a coating also reduces its viscocity which means better flowability which can help prevent roller marks and give you a more level surface. Coatings that have been thinned are vital for flowability and make pouring the product out of the bucket possible which is why thinners are also called delivery systems. A delivery system of some sort (usually an oil based thinner) is in all coatings (even the ones called 100% solids) otherwise you would not be able to get it out of the can. If something were really 100% solid then it would not pour out of a can which is why there is really no liquid coating that is truly 100 percent solid otherwise it would not pour. 100% solids is a marketing term used for a class of materials with a really high solids content and should not be confused with reality.
Much of what we use in life is made of plastic. The cell phones we use are made of plastic and so are the toothbrushes that we put into our mouths. Most resin used for coatings is naturally clear but the cheaper ones like epoxy, polyester, and latex have a yellow haze. The color in plastic is an additive which is actually metal powder (chromium and titanium) that is mixed into the liquid coating for a uniform solid color so that you can not see through the coating which also helps to somewhat hide the yellow haze on cheaper resins but does not remove it. Urethane is the only non-yellowing resin available which is why it costs more.
It is necessary therefore to give this process of marrying plastic to concrete an abstract view to ensure that all decisions precautions and steps are made before pulling the trigger. Because a chance like this only happens once in a lifetime.
