Eugenia Kraskova shares how to create a garden art foam planter.
You could paint it or better yet use it as the base and mosaic it with bits of recycle colored glass ( blue, green and clear bottles) attached with clear silicone.
This concept does not come with instructions but it has quite a few pictures throughout the process giving you an idea of how to use the product ” Great Stuff – expanding lightweight foam that comes in a spray able can ” , a knife or a chisel to sculpt the shape and sandpaper to smooth the finish when your done.
Great Stuff foam is highly expandable, to fully understand just how much it grows to do a test before starting your project.
Spray a dot the size of a dime, wait five to ten minutes to see how big it grows.
Directions on how to use ” Great Stuff ” – quoted from their website:
Shake can vigorously for 30 seconds before use.
Screw threaded end of straw assembly securely onto valve. Dispense slowly. If foam does not flow easily, do not force from can.
Familiarize yourself with foam by practicing on newspaper.
Fill openings less than 50% full. For large voids, mist water between foam applications to speed curing. Overfilling can buckle substrates.
Foam is tack-free in about 5-10 minutes and cures in eight hours.
Cured foam can be trimmed, shaped, sanded, painted or stained. To trim, use a sharp knife or serrated blade.
Can will seal itself shut if allowed to sit unused for over two hours and may not be restarted. Expect one-time use.
