Looking for help grinding or levelling concrete sitting area

[ive]

Hi everyone.
I poured some concrete with a friend last fall. We didn’t do a great job finishing because I was thinking of putting stone on top. With the price of everything nowadays I’d like to possible fix it.

The slope is not proper, I need to remedy that and it has a few dips.

Ideas?

I'd go to my local professional concrete / tiling accessory store and pose the problem. There are all kinds of things to level and re-surface stuff right out of the bag. Don't go to HD they do not carry professional products. I have used northland and they know what works and what doesn't work in our climate. Look for a local branch or for the brands that the pros use.

I would take a two step approach. Start by bushing/grinding down all the high spots and filling all the low spots with a structural grade repair mortar appropriate for the thickness of the repair. Some products require a minimum thickness and are terminated into a saw cut while others can be feathered out to nothing. I'd stick with cementitious products rather than epoxy.

After everything is relatively smooth and at the correct grade, go over the entire surface with a product such as Ardex CD, which stands for concrete dressing. It can be applied quite thinly and will take a broom finish. Break it up into manageable sections at joints or other natural breaks.

Just like prepping for paint, the quality of the finish will depend on the quality of the substrate. Take your time to get it right and pay close attention to the manufacturer's instructions for surface prep to maximize your chance for a long lasting fix.

Good luck with your repairs.

FYI if you are going to cap that slab with stone or tile that slab needs to be pitched at 1/4” per foot to control runoff afaik.
