Preserving sand sculptures

[RogerI...@aol.com]

There's some pretty cool sand sculptures here:

So I'm wondering, is there something that you could spray on the sculptures that would bond with the outer layer (maybe leaving the inside hollow) so that they could be preserved? It might be fun doing some experiments. Some kind of spray-on resin, perhaps?

Probably a Sodium Silicate solution as a first stage of hardening

Amazing works of art.

To bad Hawaii didn't represent.

I tried some sand imprint experiments. I made a sign in reverse and stuck in the sand.

Spray-on would be the best application but is has to be (should be) natural and able to bio-degrade.

I thought of using spray on starch (the kind you might use for ironing clothes) but I never tried it.

Nice experiments. It would definitely need to be some kind of spray on compound, but my idea is to make it permanent, not just to make it last longer than the next high tide. So it needn't be natural and definitely not biodegradable. My guess is some form of spray on resin. I'd give it a try but I don't have the necessary equipment. Of course, experiments don't have to be done at the beach.

 

Years ago I tried "dusting" a sand sculpture with cement and then spraying it with a fine mist of water. Didn't work, though.

According to the fine article, a mixture of water and school glue is used to keep the castles preserved long enough to be judged and enjoyed by the audience. Cooking up sand with corn starch and water should make a play-doh like substance that will harden well an rather permanently.
