We get asked so many times about using a primer that it deserves a blog post. The majority of Garage Floor installations do not require a primer if you are using a high quality epoxy. There are times however that a primer is recommended. If your floor has concrete that is old it may be in poor condition from being uncoated for many years. Road salts may have started to break it down. You may have pitted areas, a primer will help in filling in the pitted areas. Your floor may have become what we call chalky or dusty, this is where no matter how much you clean the floor there always seems to be concrete dust or chalk on it when you rub your hand over it. This is where a primer comes into play. It will penetrate into your concrete and bind up the chalky loose top layer of the floor. You should shop vac your floor thoroughly to get down to the solid part of the floor as best as possible before applying the primer.
You may be doing your floor and your square footage is slightly above the standard kit coverage. Your choice is to buy an additional Add On Half Kit or you can purchase the Epoxy Flooring Primer that will do several things. It will penetrate into the slab deeper which provides better adhesion and it will extend the coverage of the epoxy by up to 20% since the epoxy is now going over a sealed surface. So in addition to giving you another layer of epoxy for a thicker floor finish(thicker is always better) it can also save you some money.
You may have a floor that you previously coated with another epoxy that is failing. If it’s not a Home Improvement Store epoxy you can possibly still save it by coating directly over it with one of our epoxy kits. But first you must sand the floor to clean it and rough it up and then put down a coating of our Proprietary Bonding Primer. This lets our coating stick to any other kind of coating. This is not to be confused with the Epoxy Flooring Primer above which is strictly for bare concrete. The Bonding Primer can be used to go over Wood Floors or Molding prior to applying an epoxy coating to them. Or you may have a plastic or metal drain cover you want to coat with the epoxy to make the floor look really nice. Epoxies don’t stick will to metal or plastic, Bonding Primer solves that issue.
You may be the type of person who has large toys in their Garage or Man Cave or uses their space as a work shop. Or you may be the type that just wants the strongest, toughest epoxy flooring there is. This where you need and want a primer. If you have a heavy tonnage vehicle like a large Motor Home that can weigh up to 50,000lbs, you definitely want a primer. Any heavy vehicle that will have twisting or turning tires with standstill dead weight on them requires the highest amount of adhesion to avoid the epoxy being literally ripped off the floor. This is where a high performance primer is needed. Our primers are really high quality epoxies that don’t have as much Solids in them as are actual floor epoxies do, to allow them to soak a little more into the slab. They lock deep into the slab and provide a surface that the Epoxy to actually chemically bonds into thus making an inseparable layer of primer and epoxy. If you stopped at our Primer layer you would still have a better coating on your floor than the vast majority of other actual epoxy coatings you can purchase.
So there are many uses and times when you need and should use a primer and often times when you don’t. If you are unsure of whether you should or shouldn’t simply give us a call-866-532-3979 or email us at email@example.com
