technically you can use a primer as you suggest but I believe that a mechanical grind gives better adhesion because it's removing all contaminants and profiling the substrate before the epoxy is applied. Our products have a 20 yr warranty so it's important to us to get our preparation as close to perfect as possible.

Serious question. I am about to apply an epoxy. But I was told to acid wash/etch AND grind. Are you saying that I only need to do one or the other?
@epoxyflooringco31303 ай бұрын
Howdy, you definitely don't need to acid wash if you grind. If you only want to acid wash then just make sure to neutralise the acid afterwards and rinse it really really well. But grinding is the gold standard and it's the secret all installers use to ensure the epoxy has good adhesion to the floor.

Then we would grind the area until we knocked off somewhere around 1/8 of an inch of material . We never mixed water with the acid ....ever ! Nor did we go light on the area .....the area this dude taped off would need 3 gallons of straight acid . Never use gloves either ...you wanna get your body used to the abuse quick ......you don't want people commenting on your rough hands so the soaking in acid trick keeps um soft !

1L acid in 4L of water is not a 25 to 1 ratio. That is a 4 to 1 ratio (more commonly 1:4), or a 20% concentration (1L acid in 5L of total liquid). If it was 1L acid in 3L of water then it would be a 25% concentration.

@BluzFan11 ай бұрын
also 1 part acid to 2 parts water will do a much better job!!! not better than grinding just better than your example.........If the “acid etch mixture” is not properly mixed at a 10% solution, the solution will be too weak to properly remove concrete latencies or it may be too strong and etch the surface deeper than necessary, and soak into the concrete surface and contaminate it with a destructive, lingering, acidity after floor materials are applied. Never use "straight acid" mixtures for this reason. Muratic Acid is typically packaged at a 30% dilution (be sure); you want to dilute it down to a 10% dilution (1 part acid to 2 parts water).

You're comparing a mechanical grind to a chemical reaction. Grinding will always remove most of the surface contaminates at the expense of surface area. I've seen certain epoxy's completely reject adhesion on too smooth of a surface such as freshly grinded garages or basements as sometimes it does not stick regardless of what you do. I would have left your acid etch much longer until bubbling to give some sort of a fair comparison as well as a stronger mixture; excellent results can be had with hydrochloric for the DIY'er if you know what you're doing with it. - Commercial Basement Builder of 30 Years
