epoxy or polyurethane and which kind

[Kjmorris214]

hello all,

so last summer i bonding primered and painted my garage floor. However, i did not put a sealer over the top to protect it so most of it scraped off when i would moved things around across the floor that had a sharp edge. Ive read articles that recommend either hi solid epoxy or hi solid aliphatic polyurethane. Does anyone have recommendations one which to use to seal the coat that will be extremely durable and wont peel if i apply multiple coats? along with brands, where i can buy it and how much it will cost. My garage is about 200 sf

it actually sounds as if your prep was not appropriate for the products you used. I would think the primer/paint would have lasted longer than a year. I have found that the prep is 80-90% of the work and is by far the most important step to take, new or old.

I would see if you can manually scrape the current layers off, with your hand and a small scraper/ If so you should look closely at what the condition of your floor is, and plan to prep it per the manufacturers who will respond here. It may involve grinding, but a minimum it will require dealing with moisture, spills, stains and etching.

They will chime in with their products and the requirements to get good results on your floor.

More description of your current floor or some pictures may help to see what is happening.

Its not the floor is peeling off on its own. Like i said i never put a top coat on in order to seal it. I just primed and then put the behr epoxy on. it peels off when i move the refirgorator or scrape the snowblower against the floor. I read articles that said sealing it with multiple coats of a topcoat clear epoxy or polyurethane would do the trick to keep the things from scratching off the paint. If you have any recommendations on which would be harder and more scratch resistent that would be great.

I don't believe there is a product out there that is going to go on/over your current floor covering and do anything to make it work better (stay in place). The current primer/paint has failed to adhere chemically and mechanically.

The only choice I see, is the scrape or grind what you have and start over. The topcoat/clear epoxies have to have a solid surface to bond to.

see what others say...just my experience.

Keep in mind as well that you cannot apply a clear coat or "sealer", as you put it, on paint or 1-part epoxy paint. It can only be applied to a true 2-part epoxy.

Maybe just to clarify, do you mean the current paint is getting scratches from where the equipment digs in and drags along it, or is it peeling and/or flaking in these areas? If it is just scratching, you might not be in such bad shape, and most floors will do that when something like a fridge is dragged across it. If it is peeling or flaking, then it does sound like you have an issue with adherence.

You'll have to grind or shotblast and start over. A angle grinder with a diamond cup wheel may be quickest and cheapest.

Suggest doing this over, tough to 'fix' this type of floor problems and have it come out evenly.
