Yep,but use a continuous rim blade, not segmented.

Re: Improving 'floated' finish on concrete countertop

Damn, the blade I have is segmented. Might work out cheaper renting a con saw with blade for the day

Re: Improving 'floated' finish on concrete countertop

You can do it, but it's safer with a continuous rim. Go slow.

You can cut the wire with a segmented saw as long as it is embedded, but if it hangs on a piece that is loose.....

Rented a con saw and cut the counter out last Saturday. What a horrible job using a con saw!! Anyway, when I removed the shutter there were visible gaps where the concrete wasn't vibrated in properly. Glad I cut it out now. Thinking if taking Friday off work and redoing it.

Think that's fun, cut in a 3000sqft flagstone patio for 8 hours. Now that's fun.

Just repoured yesterday. Floated, then when it was starting to go off, trowelled. Much smoother surface to work with! Can't wait to polish.

Hey RichC how about some pics?

Re: Improving 'floated' finish on concrete countertop

I will definitely post some. This is going to be a thing of beauty!

It is heartening to hear your positive confidence. That is why those of us who are into forno porn are watching closely.

A lot of these people are also into forno food porn as well.

If you have to have a vice it is not such a bad thing to be inclined to.

All the best with your build.

Just realized I forgot to oil the shutter!!!! Damn! Any suggestions as to the best way to remove the timber and avoid damage?

Re: Improving 'floated' finish on concrete countertop

Tscarborough and Deejay oh, can you tell me more about the slurry? Is it just Portland and latex additive or should it include water? And sand? I'm considering using it before I start to grind. Should I trowel it in or what should I do?
Thanks

I used just portland and latex, a little bit of color (though the bug holes end up looking like aggregate). Tip I found somewhere was to put it on after you got to ~800 grit, as more holes magically appear as you start to abrade the surface. Use the 800 grit polishing pad at a slow speed to force the slurry into the bug holes. That seemed to work pretty well for me. I never notice anything that I missed.

Re: Improving 'floated' finish on concrete countertop

So today I made up a wet mix and rubbed it into any imperfections with an old T-shirt. Finish is quite good now. Can't wait to start grinding

Re: Improving 'floated' finish on concrete countertop

And some pictures! I'm fairly happy with the finish now. Will more than likely end up working in the slurry at 800grit as you guys recommended.
