Treatment of concrete slab for outdoor kitchen

[DaErkiman]

I am casting a concrete slab for the outdoor kitchen where I will have an inset charcoal grill. It will be outside without a roof and will get both rain and food/grease splashes, so the question is how I should protect it.

I'm not too concerned about how the appearance is affected by the treatment, the main thing is that it should withstand the heat from the grill, rain, dirt, and grease without becoming damaged or difficult to clean.

Does anyone have tips on which treatment is suitable?

Thanks for the tip! Has anyone tested this? [link]

This was the treatment, and after a first major barbecue with accompanying marinade spills, it seems to work. Just wipe it off and it left no stains, although it has become a bit black from heat/soot right around the grill.

A bit of a late reply, but concrete oil should work really well too.

Really nice table, how did you build and dimension that?

It would have been cheaper with oil, we'll see how it works after a bit more grilling, rain, and rough weather.

Everything is built with 80x80 aluminum profiles that were left over when the exhibition system was changed at the company. Screwed together in a couple of minutes with the built-in quick fasteners.
We'll probably reinforce it a bit with some angle irons, and we'll mount a shelf underneath and some doors.

Had you lived in Örebro County, you would have had it delivered, I have 7-8 liters to spare.

I have the same grill as you (mastertouch) and plan to make a similar solution so I get more landing areas. Very inspiring!

How has the treatment held up for you?

Our countertop was as smooth as a freshly resurfaced hockey rink the first week, but then it gradually got bumpy to now look like this.
It still repels liquids well, at least.

My disc has gotten a couple of grease stains that won't come off, but they don't bother me much. No bumps, still silky smooth and water beads on the surface.

How long did you let the disc burn before treating it and how many turns?

It was cured for a week, then I applied 3 layers.

Follow-up on our countertop if anyone else is interested in a concrete slab. After getting in touch with the retailer, we concluded that the roughness likely occurred because we wet sanded (800) after the first coat. We sanded everything down and redid the process with three coats and now it works great! It has been about two months, and the water beads up, and so far there hasn't been a single stain on the slab despite contact with lemon, vinegar, and grease splashes.

Have treated our countertop for the outdoor kitchen with water glass in 4 coats. Now I'm thinking of waxing it with Topper from WS Form.

In autumn, you have to wait for the dew to disappear in the morning. However, there are sunny days ahead, so it should work. Does the dew decrease if you cover it with a board overnight? I'll try it tonight, but considering that I don't get dew under the carport...

How was the result with water glass and topper? Is it enough with just topper if you're not looking for a completely glossy surface?

Turned out well, I'm satisfied, but I'll probably add a couple more layers of topping this season. No idea really if the vsttenglaset helped.
