How to Make a Fake Tree Out of Foam?

Using foam is the easiest DIY technique to carve out trees. Also, it has almost zero health hazards and risks while working with it. So, without further ado, let’s get into the detailed process –

How to Make a Fake Tree Out of Foam?

Step 1: Prepare the Base

In order to make the trunk of the tree, get a 5 to 6 feet long cardboard tube from online or local stores. If the size is not perfect, buy several tubes.

Take glue and attach each end of the tube on top of the other to form a long trunk. Let the glue dry so that the tubes can hold their shape together.

Step 2: Spray Foam Tree Trunk

There are various types of spray foam, but for this project, make sure to get the expanding one from the hardware store. It is better to buy the canned one.

Spray the foam on the trunk in a vertical pattern from top to bottom. The line should not be more than two to three feet. The gaps are necessary between the lines, which leaves room for them to expand. Once the foam dries, it will fill the gaps.

Step 3: Carve the Foam

Let the sprayed trunk dry overnight to remove the gooey and sticky texture inside the layers. Then, take a bread knife to carve the roundness of each layer. To give the base a natural look, carve with a serrated knife to bring out the uneven and rough texture of the trunk. 

Remove thin slices of foam from top to bottom. It creates bark-like crevices on the base. Do not go too deep. Otherwise, the artificial tree trunk and branches will not be sturdy enough after installation. 

Step 4: Paint the Trunk

Take four spray paints in shades of grey or brown and black. Apply the first layer of grey on the trunk in a vertical pattern. Do not overcoat the layer. Or else the crevices will not look natural!

Then, spray light brown color by keeping some gaps between the foam lines. If you want, you can overcoat this layer. 

Now hold the dark brown spray bottle 8 inches away from the trunk and cover the foam in a random pattern. Make sure not to hide every nook and cranny of the base in brown. Otherwise, the tree trunk will look too artificial and dull. 

Last but certainly not least, use the black spray to make spots over the brown base. And spray camo paint in between the crevices. 

To smooth out the combination of these colors and splotch, apply dark brown color over them. Do not touch the bark now and let the paints dry for several hours. 

Step 5: Install the Tree Base

Fill a basket or pot with some sand and rocks. Then, install the trunk in the pot. Make sure to gently tap the sand around the trunk on the ground level. It prevents the base from leaning sideward. 

Step 6: Make and Place Greenery

You can buy fake tree branches online or can make your own. For that, take some plastic straws and attach paper-cut leaves with threads and glue. However, the DIY foliage can be a bit troublesome to attach to the trunk.

With a nail or drill bit, make ⅛” small holes on top of the trunk. Then, add some glue to the holes, and insert the fake stems. For the store brought branches, you need to use wire cutters to separate them before installing them. Now you can place the tree anywhere you want.

Is A Fake Tree Made of Foam Worth It?

Most of the readymade fake trees are too expensive, and you cannot even make alterations to them easily. And if you want an asymmetrical tree, it is always better to carve the foams to come out with a tree shape of your preferences.
