I used the 1" foam when I poured my kitchen countertops 5 years ago (before I'd seen anyone else do this). The issue I ran into was keeping the foam from floating to the top of the mixture, thus preventing the concrete from reaching the top of the form edges. I noticed you struggling with the same thing before cutting away, then showing the concrete setting up before covering it. Do you have any tips on how to keep that foam from floating on you? Also, is there any reason you didn't just leave the foam in? (that's what I did with mine). Thanks!
The best way is to screw a wooden slab across the top of the form walls. That way the foam can't float any higher than the top of the walls. And I removed the foam to reduce the miniscule amount of weight it adds. Totally unnecessary
I recently built a top using this forming method but on a larger scale. The problem I ran into was that, because it took several buckets of mix to cover the bottom of the form, when cured and flipped you can distinctly see the separate pours on the top/finished surface. Do you have any tricks to avoid this issue? I have one more to pour and would like to have a solution before I get to it.
There are two ways to fix this issue. Simplest way is to pour the second bucket directly on top of the first buckets concrete, not next to it. Second method is getting a larger bucket :)

You could of mixed the patch alittle wetter to avoid them air bubbles. I make compass rose tables that has a ton of detail and rock face sides n gett no bug holes everytime. Add the water to the mix
Here is the link to the mix, and you can find a TDS on this page to get very detailed info on how to use the product under any circumstances globmarble.com/concrete-countertop-mix-white.html You could use mesh and rebar to make the concrete have stronger tensile qualities though :)
Your videos are fascinating to watch. You explain everything very well. But, I haven't been able to find if you can use your live edge molds on a concrete overlay project on an existing countertop. I saw the one where you created a stencil but was curious about the live edge mold.
You didn't show a closeup of the top surface. Is it as perfect as it looks? That 3/4" thick edge. Is it strong? What about accidental knocks with saucepans? Great work by the way, I'm quite impressed.
Thanks! The surface is perfect, you could see it on the reflection at 19:04 in the video. The concrete is very strong, after 28 days the PSI is at 10,730 for our precast mix.
In most of the cases you don't need steel reinforcement if you use our precast mix. Our precast mix contains allot of fibers. globmarble.com/concrete-countertop-mix-white.html You may need to extra reinforce in case if you make a large panels or thin parts.
@@GlobMarble what happened to your original ratio in mixing the concrete? why did u have to guess the blend ratio in the bubble fix? it would have been cooler if u presented a fixed ratio bro... anyway i liked the hollow idea...great help in the weight issue...👍👍👍
2 inch it's a most popular countertop thickness, we also offer few 1.5" edge molds. Details at globmarble.com/decorative-concretes/concrete-countertops/concrete-countertop-forms/edge-forms-and-liners/

if you had used a vibration table do you think it would gotten out the air holes on the sides?
A lot more bubbles would have been taken care of with a vibration table yes
What was the cutting jig you used when cutting the 45s on the edge form? Really like it, can you share a link please?
I think this is the exact one I have :) www.harborfreight.com/miter-box-with-saw-66562.html
Great work! Gonna try this on my roof top. Thanks so much!👍😊
Good luck!

This will make the concrete weaker!
@@GlobMarble or use FLowControl....
What creates tensile strength in your concrete mix? Especially when making larger cantilever counter tops?

I loved the finish, best color on youtube so far, great job!
Thank you
So cool brother very inspiring!! Thank you
My pleasure!!
Absolutely outstanding
Thanks a lot!!
how thick is the foam you are using?
1 inch thick

Hola amigo puedes poner subtítulos en español en próximos video saludos
Looks awesome!
Thank you .
If you would have wet your concrete when you were mixing your slurry. You would have had a color guide to instead of waiting for your slurry to dry.
Wet concrete it's one of usable option. It's little more accurate in dry concrete. Thank you for the comment anyway...

one question.can use basalt fiber instead of ar glass fiber in gfrc?
Yes, basalt fibers are pretty good option.
