I put a small 1/8" flat piece of steel under the edge to shim the counter, creating a slight slope for water. A thick bead of silicone caulk around the edge, and set the counter in place (very heavy).

Still have to put a sealant on the concrete. I thought I'd wait a little longer, to be sure it is fully cured.

We also continued a little more stone work on the sides and front.
The nights are starting to get cool quick. I hope we beat the weather.

Mike,
How long did you wait before the grinding ?

[mfiore]

David,

I followed recommendations from the book "Concrete Countertops" by Fu-Tung Cheng.
I did the initial grinding, starting at 50 grit down to 400 grit the day I pulled the forms, which was 4 days after the pour. I waited until day 10 to do the polishing with finer grit pads.

Hi Mike,
The countertop looks really good! What type of grinder/sander did you use?

I just make plain old concrete surfaces, for the most part. Pretty rough, usually. Grinding a countertop ( even a small one) is a LOT of work!

Just put in the slab for a storage space to the right of my oven today. I am starting to feel the 'age'. (5) 80# concrete. Ugh.

Lars.

This is the grinder/polisher I used. It's designed just for this, with a water intake. The discs are a hook and loop system that exchange easily. It took a fair amount of time. The edges were more difficult. When I thought I was done, my wife wanted the bottom side of the cantilevered portion done as well. I could have kept going to get a real mirror like finish, but I wanted it to look like concrete still.

Great job Mike!

I used concrete on mine as well but did a pour in place with multiple color batches in an attempt to simulate old multicolored weathered stone.... I'm not pleased with the results. I ground down too much trying to expose the different color mortars but while doing that I exposed the larger aggregates in some spots.. It looks like it has white pokadots on it.... Doesn't give you that 'Ahhhrrrrrr' feeling, ya know?

As always Mike great job.

How's it going Mike? Are you going to get that roof on before the snow flies?
