Russell, did you find the tools necessary to accomplish this concrete polishing online? Which tools did you use? This is a useful thread! :)

I am going to pour a 2.5" counter for an outside cabinet within a few weeks. It will have a marbling technique that might interest you.

Thanks Utah for putting this thread together.

I'm in the infant stages of planning my concrete counter tops. I look forward to seeing your marbling technic and following the threads. Will that be a pour in place or cast upside down?

I want to cast a 2" upside down its seams that it would be a little easier to form, especially for a pretty much a rectangle. The same size on both sides of my oven. One side will have a under mount sink opening. Can I use the same form for both? What is the minimum width of the concrete needed around the sink?

The counter in front off my oven will be quite complex It might be better to cast in place.

Upside down.

A one and a half inch counter is sufficient for strength, and would be much easier to flip. From what you described, you can use the form for both sides. But, that will be days apart on separate pours. You will need to take precise notes if you are mixing in color to make sure they match.

I agree with Stoncutter. To be a perfect match to the counters, the counter in front of your oven will need to be an upside down also. Don't let it's complex shape scare you. Take a piece of 1/4" luan (or cardboard even) and make a template. Turn it over and make your form to fit the template :).

No matter the thickness of the counter, don't overlook full support underneath it.

Are the counters not set on a bed of mortar or sort to facilitate leveling and anchoring?

I was hoping to keep the counter in front of my oven up a bit to allow the flashing under the vent area bricks to channel any water intrusion into vent area, under the counter top away from the insulation and out the front. I was figuring small beds of mortar about a foot apart.

On my cabinets tops I'm figuring a 2x4 front and back and 2X2 on 16" centers.

What are you considering full support?

2x2 is a bit flimsy...use 2x4 for everything.


Mine cabinet is going to be framed with 4x4 oak timbers...for aesthetic & design reasons....and the substrate beneath the concrete is going to be 3/4" pt plywood, felt, then 1/4 perma base.

Like natural stone tops, you don't need to adhere concrete counters down with mortar or glue....silicon is all that is needed. If your counter is outside, then make sure to get exterior grade....better yet use Lexel, it's the best.

Thank for the great info..........You choice for 1" of substrate.......Wow......Am I missing something?.......Although it was you that commented on: Error on the side of safety:......... Caution there is wisdom in that.......................... Glad to see you practice what you preach...........:D
