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.
