## Questions & Answers

**Q: If I pour this into wood, would it stick?  I am trying to fill holes and place rocks and have the plaster hold the rocks like a mosaic.**
A: I think you would be better off sticking the rocks in with something like caulking or E6000 glue.  Not sure the cement would hold and it was quite expensive.  You can get caulking in brown or grey to blend with the wood colour for any areas that show.  Just a suggestion.

**Q: When formed into say, a 4” flat stone, how many will this container make? Starting small before committing fully to larger bag!**
A: I have the 5 inch round mold from happy dotting company. I think this bag is going to make 3 rocks if I am lucky. Ive already made two and the bag is almost empty :(

**Q: When molded into a rock, are these strong or do they break easily?**
A: I’ve made many in  molds and had no problems.  I haven’t dropped one but would believe mine are strong enough to hold up.
Love painting on them and friends like them.

**Q: Is the same than hydrocal?**
A: Not sure, have only used Ultracal 30
