Mark, This was an awesome video. I watch a lot of these to get ideas and tips and most times I’m disgusted with the presenters because its clear they are clueless and just guessing (trial and error) when demonstrating their projects. It was very clear from the first 60 seconds that you Sir are truly a master craftsmen and apply math and logic to your projects. As an Engineer myself I was “Glued” to your video. I will make contact when I decide to attempt this one. Thanks again for sharing your knowledge with everyone. -Tim

[@robohippy]

This type of concrete work has come a long way in the 20+ years since I quit doing it. Watching the wet pour, I was thinking maybe you need one of the very old school jitterbug tampers...

[@alexamickey]

this man is a genius

[@alexdavid3460]

There are no glass fibers coming out from the top surface? You don't need an extra thin concrete layer without fiber glass so that fibers do not appear on the surface? How do you deal with this problem?

[@TrinicLLC]

The reason you don't get glass fibers in the face coat is because they have a lower specific gravity than the sand and cement. So when you pour the mix into the mold the fibers float up away from the face. You could also replace the AR glass fibers with PVA fibers to make an ECC mix. PVA fibers aren't visible to the naked eye after casting. PVA fibers are dosed at about 1/2 the rate of AR glass, but cost 2x.

[@benjaminparrillo9727]

Well done. Have you ever substituted raised grade board form lumber for the MDF when moulding your rubber form? I love the concrete but I'm sure a wood grain finish would be another great option.

Hi. Great video. Which rubber product would one use to make this type of bendable mold?

[@TrinicLLC]

Polytek 74-20

[@mohsenazizian4108]

Thank for sharing this video. There are both uhpc and gfrc in the title. which one do you mean? I think they differ in case of mix design.

[@TrinicLLC]

UHPC refers to (according to ACI) strengths above 17,500 psi. GFRC can be any glass fiber reinforced concrete so it can actually be both.

[@sighyawn54]

how long is the process from start to completion?

[@jameskid81]

Do you think it would be possible to do it straight on the ply, if you glued a silicone border round it and waxed it? Those silicone forms are hard to come by and expensive one would imagine. cheers

Okay so for anyone else interested in the calculation. The minimum side wall needs to be .75" larger than the table, bottom needs to be .5" larger, if the table is 2x8 ft thats about 51lbs of the 74-45. They sell in 4, 16, and 80lb kits

Do you sell the material to make the mold? And, will the mold hold up to a 4" pour? If so, you may have just upped my profitability on my most popular item by a significant amount. Also, whats time zone are you in? I'm in HI, and Guam. Don't want to call you in the middle of the night.

[@TrinicLLC]

We do sell the polyurethane rubber to make the mold. That only needs to be about 1/2”-3/4 thick and will last for close to 1,000 casts if you are careful with it. The support for the mold you would need to make stronger to take the weight of 4”. Also why so thick when you can use GFRC and do it at 1” and make it look like it is 4”?

[@bennettjones9696]

It's the center support for a 24"×48" outdoor coffee table, in the shape of a university mascot, thats small on bottom, and wide on top. I do oval and rectangular tops and bottoms. Top thickness is 2" with wire mesh reinforcement. Bottom, which is 18"×36", is 2.5" thick, reinforced with wire mesh. Think of a bull head with Horns. My goal is to lighten it up. I tried a pink foam board center, with 1" cast all around, which made it light, but didn't pass a strength test. All 3 I made in testing failed. I'm currently using pink foam board for my molds, which are 1 time use.
