a sand question
Just wanted to say hello & thank you all for all you offer here. Oh how I love the web, with just a few clicks on Google ... "there you are....look at this.....lots people who get excited about the same things as me, I am not so strange!"
I have been busy lurking/learning, having fun in the mud and creating with all your know how, but today ran into a bit of a problem casting a gunnera and I donÂt know if it was the sand.
I have always used a hypertufa mix before but I wanted the more defined look many of you are getting.
The plan was to cover the leave with a thin cement layer and then put on wire and finish with another layer of a hypertufa mix so it wasnÂt so heavy.
The sand I am using is called "extra fine"
Mixed up 2 extra fine sand + 1 cement + water and the mix didnÂt look to "wet" just "nice" but as soon as I tried to move or even touch it on the leaf to get it to the edges it turned from sort of hard/wet sand consistency to a runny/liquid mess. (Think of playing with cornstarch and water.) It is like the more you touch it the runnier it becomes. I gave it an hour to "think" but again as soon as I touched it it seemed to liquify again.
Do you think this because the sand is so fine?
Has this happened to any one else?
Thanks for any help here
