Countertop outdoor kitchen

[Living]

I have built an outdoor kitchen and I'm going to sand and treat it now.

I'm wondering which sandpaper I should use, wet or dry paper, and what grit? The idea is to sand by hand.

Then it must be treated, and I read that there are different methods for that. So my question is whether I should use concrete oil or impregnate with 'Akemi Antifläck Nano-effect'?

The outdoor kitchen is outside without a roof, so it should withstand heat, rain, grease, and dirt, and it should be easy to clean.

Anyone have any suggestions? All tips are welcome.

What are you aiming to achieve with the grinding? Hand sanding away the outermost "dust" works with wet sanding, but if you're looking to reveal the aggregate (stones), then hand sanding is probably not a good solution. I've used stone oil on my kitchen counters (not specifically Akemi but similar), it's probably necessary to treat the surface regardless of whether it's indoors or outdoors.

My slabs have color pigment mixed into the cement, but regardless of pigment or not... it gets a little darker with the stone oil.

Thank you for the response and how nice your slabs are. I have cast my kitchen countertop in place so it didn't turn out as smooth. I was hoping to improve it with sanding. But I can understand if I can't achieve that by hand. The most important thing is that it doesn't get so dirty and that I can keep it clean when it's in use.
Do you have any tips?

I have used Herdins Hard Wax Oil on my outdoor concrete slab. It works very well as protection against grease and other elements, and my slab is very rough due to poor casting.

I have used Herdins Hard Wax Oil on my concrete slab outside. Works very well as protection against grease and others, and my slab is very rough due to poor casting.

So you don't think I need to sand it? Is it enough to use Herdins hard wax oil?

If you can settle for a somewhat rough surface, it works fine with Hardwax oil.
The wax removes some of the roughness, making it a bit smoother.

If you can settle for a slightly rough surface, Hard Wax Oil works fine.
The wax removes some of the roughness so it becomes a bit smoother.

Isn't it just for wood treatment and indoors??

Thanks for the answer, not sure if it's worth sanding with a diamond sander, maybe I won't get it any better anyway???

Thank you for the reply and how nice your records are. I cast my kitchen counter in place so it didn't become so smooth. I was thinking and hoping to improve it with sanding.

I would probably recommend renting a sander and taking it down enough that you are satisfied.
But you can't sand by hand...I'm pretty sure about that (been there done that)

Stenolja I prefer above all else...it's approved for food.... .

I would probably say to rent a sander and take down as much as you are satisfied with. But you can't sand by hand....I'm pretty sure about that (been there done that)

I prefer stone oil above all else...it's approved for food contact.... .

Thanks, I will check today if there is a sander available for rent in our village to start with.
