What is the correct curing time for hypertufa pots and statues?
Curing Hypertufa in plastic (poly) film
I have heard any where from 1 week to months.
My husband and I just started doing projects with hypertufa.
We really enjoy playing in the mud creating things,but we would like to keep them.
If they are not done right, I imagine we will just have piles of stone like material in our back yard.
Hi Trisha, so much of the curing time depends on the mix itself (percentage of the ingredients) temperature, and humidity.
To be on the safe side, cover with plastic for at least a week, and then carefully unwrap and spray with water daily for another week.
If it's really hot, for smaller items I would use a water bath method, and leave them immersed completely for a week or two; for larger items, leave them covered in plastic film and spray to keep them wet. Concrete can take a long time to completely cure; the thicker the concrete, the longer the time.
You will get more confident as you make more items, and learn the optimum time to cure for your conditions and situation. See more about curing hypertufa here.
