I Made Another Giant Hypertufa- So Many Problems! 

Did you wet the 'old' cement bottom prior to building the sides? From the other videos I've seen with cement, etc, it has to be wet or the old and new won't bond. Another question: Do you ever add about 1/2 to 3/4 of the water you should need to mix it and then tweak it once it's thoroughly mixed? I'm thinking that if I approach it that way, it will mix easier and I'll be able to still have a drier mix that will hold its shape easier. What do you think?

Use beach sand as the inside mold I do it all the time it helps hold the hypertufa sides! You take the sand out when it is cured. Many times, I line the inside with a garbage bag or plastic wrap than add the sand. Thank you for your video the hypertufa pots are so addictive and fun to make.

I'm thinking of making a bird bath about the same size, but with sides only about 3-4" high, and then the center might only be about 1 1/2" to 2" thick. I'm planning to have two pedestals under it. I was thinking 3 pieces of rebar run lengthwise might be good to keep it stable horizontally. Do you think the hardware fabric would be better at it? Since it would be supported on only two pedestals, my concern is the middle, which I don't want to sag at all.

I thought the hupwrtufa was foam so now I’m done and good . Thanks for the lessons ! 🫥

Great video. Got me noodling on how I'll approach my project. I am considering dollar tree pool noodles to hold up the sides. Will dry test before adding the hypertufa mix. Thank you

Have you thought of using sand to help hold up the inside? You could lay down another piece of plastic over it and then put in your sand and press it down to hold up the sides. You could even lay a flat board on top if you got it up to the height of your hypertufa. You might also be able to use the sand to make your walls thinner and the pot higher. Just my two cents worth and if you use it I hope it helps. I love your Channel and thank you for the ideas!

I make 55 gallon tall light wieght concrete planter pots....I use a hammer drill and a large concrete mixing bit....I love giant pots....very pretty. funnily to build up the sides,,,I hand pound..it works...I use a rubber mallet when hands get numb...I also make an irregular (marble effect)using while portland cement as first layer against the liner before building up thicker with cheaper regular cement combination.. I put the lid on my 55 gal black feed container ...very durable $59.00 tub...and let it sit for a couple of days then lay on the side, pull out the drum plastic insert..to get it started then stand it up and it pops right out:).55 gal can liner 3mil...yup it works great...Id love to send you photos of finished product...after it dries out throughaly, I add dried moss to some of the grooves made by the plastic...these are magnificent. Unfortunately difficult to sell because...of the wieght and possibility of crackign during shipping so I sell them locally for around 400 each.

How do you work out how much ingredients to make a large tall pot nobody seems to give a rough estimate can anyone give some kind of info plz Ty 😊

Maybe a few pieces of metal or just wire fencing inside

perhaps a water filled bladder would work greak for an insert in one of your irregular molds...however if you get the water to dry just right you do not need any insert...as evidenced by my giant tall planters of 55 gal capacity

You could have packed it with sand.😂😂

3:40 why you gotta be so violent ? 😂

Hi, have you thought about using different sized blue wading pools by any chance? Also, if you have any successful large planters, could you send me those links please. Have you considered using pond tubs? Maybe there are some that may fit in each other nicely. Do you think it might be possible to incorporate layers of chicken wire, in order to keep large tuffas walls from caving in while still wet? Can tuffa be laid in half thicknesses, let stiffen & then build up to its interior girth by using chicken wire layered in between? How about using refrigerator cardboard as a frame within a frame held together with large aluminum nails that are used with aluminum rain gutters. The nails are used to keep gutters from bowing out with weight. Oh, on the large form planter form from H..l, maybe you could use heavy duty black lanscape edging together with chicken wire. Maybe if you could build a light weight wood frame for the inside, instead of loose pieces, that are more difficult to manage. Old corugated fencing could do the trick too, just make sure to interface it with plastic or cardboard so the mix doesn't stick to the metal. Please let me know what you think & send me links of videos. Happy mud slinging😀🌱🥀 Emily

I just read one of your responses re the weight of your tub. I wonder if using perlite wiuld have made it lighter. Vermiculite holds water as perlite does not.

I had a giant one made - I am sure it is 10 years old - and more beautiful each year - love it

Should have left out the plastic,and sat it down in a large pile of sand supported by a frame

Put a bag of sand inside and it will mould to the shape

Also if your adding cement to already half curred or curred cement....use diluted elmers glue to the mix or even concrete additive which is more money but works the same

Hi Kim and friends and family. I'm sorry that it didn't work out ok on the big planter, I'm sorry to say that you have to make a box mold . Why because my hypertufa mold is 24 in. H 24 in.L 24 in W. I have to use chicken wire over the box (mold) to make it the hypertufa light and use less. Soon will send you a picture.

Given your dry mixtures that used ,what would you say the correct amount of water you should have used in litres.

Maybe a bladder of water. Like a large garbage bag!?!

please explain what is "leaching" ?

Add plasticiser and less water. Turned my mix into clay.

Good job thanks for tutorial ,

could you not turn the mold over and mold it from the outside. like a turtle shell?

Is there a video of the. Unmoulding?

Is there a hole on the bottom for drainage.

I haven't done a Hypertufa before. Is one able to let it cure for a day or two and then continue to build up the walls with a new mixture?
