Hi,

I have cast a small concrete pad for an outdoor kitchen area, its about 5' by 12'. I'm grinding it to expose the aggregate, and then plan to polish and seal it.

I'm looking for recommendations for penetrating sealers that will work with a polished (or semi-polished, I can stop at a certain grit if needed) surface, will last in the sun, and don't change the appearance of the surface much (i.e. not shiny). I'd also need to be able to add some level of non-slip to it.

So, summary, I'm looking for a penetrating sealer for:

Area: 5' x 12'
Concrete Finish: Ground and semi-polished or polished
Environment: outdoor, in the sun
Use: pad under outdoor kitchen
Desired final finish: as close to the bare concrete as possible (as matte as possible, not wet look), sealed, and non-slip

Any idea why not, other than slipping hazard?

Just wanted to close this out, I ground the concrete down to around a 600 grit to expose the aggregate, hardened it with Ghostshield Lithi-tek 4500 and sealed with Ghostsheild Siloxa-Tek 8505

The 600 grit finish keeps it safe in the rain, and the hardener / sealer has made it very tough and stain resistant. Good result all round.

Wow this looks awesome. I have a new 20 X 25 brushed finished concrete slab put in, I have similar requirements where it should sustain heavy rain, extreme hot weather ( TX) and easy to clean up if there are any oil spills. Can you please recommend me something? I really like the finish product of yours, any thoughts what would work for me? Thanks in advance.
