Treatment of concrete slab for outdoor kitchen

[Den ofrivillige snickaren]

This treatment was done, and after an initial large barbecue with accompanying marinade spill, it seems to work. Just wipe off and it left no stains, though it has become a bit black from heat/soot right around the grill.

Did you sand the countertop beforehand? If so, how?

I'm about to fix mine

Thought about sanding these off before I treat them at least. Is it worth renting a sander or better to buy one? Or is it possible?

Follow-up on our countertop if anyone else is interested in a concrete surface.
After contacting the retailer, we concluded that it was probably because we wet-sanded (800) after the first application that the bumpiness occurred. We sanded everything down and repeated the process with three applications and now it works great! It's been about two months and the water beads up and so far there hasn't been a single stain on the surface despite lemon, vinegar, and grease splatters.

Thanks for the great thread. Did you use a machine or sand by hand when you sanded down the countertop again? I assume it was with wet sandpaper. What dimension or whatever you call it?

Also, I wonder if you apply the treatment with a brush, roller, or spray? And how long do you wait between the different applications?

Hope to hear from you.

All the best.

Hi, I think I used grit 40 regular sandpaper, but with water. Treated the surface with "stenfix" (note they have different types) used the yellow side of the dish sponge. Did it 3 times, the surface was saturated between treatments.

Hi MrLanderstedt. I have the same issue, did you end up with a smooth surface in the end? If so, how did you do it? Considering using the orbital sander and taking off 2-3 mm. Regards, Henrik

I started replacing the wall on the cabin instead,

Called a company that didn't recommend that we rent a "pro slip" as it would eat up the concrete..

but I tried filling the holes with white epoxy and then sand with a regular orbital sander and regular sandpaper. It's taking a long time and I don't think it looks very nice so far.

Bought a house and got more kids so the project has been on hold... but I'm going out at the end of the summer and hope I can finish it then. Considering buying better sandpaper via Wish. I read about it in some forum/Facebook group. I'll get back to you when I've made progress unfortunately maybe not so much help...

Bought a house and got more kids, so the project has had to rest... but I’ll head out at the end of the summer and hopefully, I can finish it then. Considering buying better sandpaper via Wish.

Thank you very much for the answer, good luck with the project

After contacting the retailer, we concluded that the roughness probably 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!

Hi, I'm looking for what type of treatment you did here, but I can't find it. What product/method did you use for this?
Best regards,
Jonas

Hi, I used this product. Now after four years, we have to sand it down and give it a new treatment, which feels completely okay considering it's our kitchen counter that we use daily.

How thick is the slab? What reinforcement have you used? And what do you use where you're going to have the holes?

Update. After we began sanding clean to apply Hey'di Top again, we decided we never wanted to endure it again. Despite the sander, it took several hours as the sandpaper clogged almost immediately. Instead, we chose beeswax, and the result was very good! Sure, it doesn't resist citrus as well (it gets stained if you don't wipe it up within 10 seconds), but the advantage is that you only need to sand the stain lightly and then apply beeswax to the affected area, and the stain is gone.
