Hello

I'm getting a concrete slab that's been cured for two weeks and is then treated with concrete glaze.

The slab will be outdoors in all weather conditions. What's the best treatment? Should I apply a few more layers of glaze? I'd like to have a surface that resists grease stains and other spills, and I also want to maintain the gray concrete color.

Made my own dining table a few years ago. Bought this variant:

but back then there were 500ml bottles. So it's quite a lot for a top with 1L.
So far it has withstood 2 kids and several parties with red wine spills. Tried some test pieces first, and this one was the best, we thought.
Working on a countertop for the outdoor kitchen and plan to use the same, but we're not quite finished there yet. I've sanded the surface with 800 grit and then treated it.

Looks really nice! I saw that the one you linked to was out of stock. Do you have to sand before treatment, or is it fine regardless?

I know that the one I'm getting is treated with some kind of lasyr, do you know if that's good or bad?
 
On the table (see image), I have only treated it after it finished burning.
Good question, I assume the supplier should be able to answer that. This one I used got absorbed relatively quickly, I thought. And now the water beads on top.

The stain is said to have penetrated the concrete, so another treatment might conflict; more stain can provide a denser surface, but check with the supplier for more details on what they have used and how much.

What could the consequences be if another method clashes?
 
Impossible to answer without knowing the original treatment and the intended treatment. The easiest way is probably to find out what is going on today and see if it can be repeated if needed.

What is on today is concrete glaze. Is glaze a good method for a concrete bench outdoors? If so, maybe I'll continue, but are there perhaps better alternatives? Beeswax? Oil? Lacquer?
