Waterproof Foam Rocks

Here is a technique for you to make “rocks” from floral foam. In this example I have covered just the base so that I can still use the foam as a water source in my designs. You could also completely cover your foam to give some lightweight but effective additions to other types of designs, particularly with the variety of coloured foam available these days.


Rocks 11. Shape some pieces of floral foam smoothing them off with fine sandpaper or an emery board.




Rocks 22. Melt a small amount of wax in an open pan placed above a saucepan with boiling water (a modified double boiler for the cooks amongst the readers).




Rocks 33. Dip the foam into the melted wax to give it a thin coating and place on plastic, wax side up, to dry.




Rocks 44. Repeat Step 3 a number of times, until you are happy with the desired thickness of wax. I generally do the bases/sides four times to ensure they will be watertight when I use them in my designs.
