Can anyone tell me how I can get sand to stick on the surface of a mold
before I put in casting urethane? |

Mabye you can use natural resin or sillicon grease. But I don't know if this
reacts with urethane, you should figure this out first.

Good ideas. Please tell me what "natural resin" is.

I don't know how to explain "natural resin". It's a translation from dutch.
The dutch word means the sticky substance in pineapples.
I came upon this because I have heard about problems with making
polyurethane blocks. To prevent the surface from being irregular, or to
prevent the polyurethane from sticking to the mold, they used substances
like I told you.
