Sealing Bare Concrete Garage

[pmkoch]

When I moved into my house, the original owners had laid down laminate indoor tile in the garage. The house is 20 years old so the tile was all cracked and it has a nasty adhesive underneath. I've removed all the tile and plan to diamond grind the entire surface this weekend.

I don't want to put a nice epoxy down because I don't plan on living here forever and frankly don't want to spend the time or money on it.

Should I put some type of sealer down afterward? Will I see swirl marks if I just apply a clear sealant to it?

It will be a rough porous surface when you are done. An epoxy sealer would be a great choice.

I ground my floor, which is much older than yours, and then I applied a densifier so I could get rid of the dust the floor created. I've been happy so far.

When you grind a floor, you ;open it up' and make it more susceptible to damage from the elements and it becomes a dirt magnet. A densifier will help with the first part, but perhaps not completely. For those that go that route it is usually best to grind a second and even third time, getting finer each time and apply a sealer after the last grind. Even then this becomes difficult without doing a full grind and polish.

If it were me, I would do something like a clear polyurea, or a normal polyurea or epoxy coating system. Here is a look at a recent clear project https://www.garageflooringllc.com/2017/05/12/clear-gloss-garage-floor-coating-polyuea/
