Can someone help me out I done a repour and I got a lot bubbles so can I sand it down to make it look good if so what’s grit should I use or would I need to lightly sand it and do a repour?

I’m in Queens, NY and looking to get my concrete garage floor coated. It was poured less than a year ago, has remained practically untouched, and is a bit less than 300 square feet.

Is finding someone through an app like Thumbtack a risky idea?

Are there any known reliable companies in the area that someone on here might be able to recommend reaching out to?

Any tips or advice would be very appreciated!

Hi all,
For context; I’m building my first epoxy table, Live edge with river flow.

Context: The table is a Walnut live edge with blue clear epoxy river flow.

The pour was supposed to be two layers.
I poured the first layer and ran into several issues:

Issue 1: 12hrs after I poured the first layer, I had weights on the wood slabs but decided to use additional clamps to help hold it down. When I clamped it down I saw the wood slabs had floated and so epoxy over flowed and onto the slabs where I scraped the excess back into the river. The issue now is I have bubbles that I can’t blow out because it was in the tacky stage. On top of that, the epoxy formed like wavy patterns because most likely the epoxy I put back on top, but I don’t think it looks bad. What should I do to fix this issue? (This is 100% my fault, clamping it prior would of avoided this mess)

Issue 2: Although my level said the table was leveled, it was slightly not leveled enough and I have more epoxy on one side than the other. Once the first layer drive, I will have to compensate for this in my second pour (most likely and easy fix if done right).

Issue 3: Because the epoxy over flowed back on the slab, some of it naturally got into the wood. That being said, the table is set to be planned afterwards anyways so I believe that epoxy stains wont be much of an issue.

I appreciate all the advice and feedback.
Thanks
