Step 1: Materials used

Picture of Materials used
Materials used:

1 can grey primer.

1 can black spray paint.

2 different color red spray paints.

1 can of glossy clearcoat.

1 or more cans of crack and gap spray foam insulation.

parchment paper.

Optional Materials:

Spare clothing

black birds, I purchased at the dollar store as well as online.

fake rats from dollar store.

assorted fingers, ears, noses, eyeballs. I picked these up from the Dollar store as well.

fake hands

You can purchase all of these I'm sure from most halloween stores but they are often pricey. Cook at your local thrift/dollar stores first then online for these kind of cheap props.

Step 2: Prep your working surface

Lay down a few sheets of non stick parchment paper. The gap and crack foam were using for this project will stick to anything it touches.

It won't stick to the paper making removing it easy once were done

Step 3: Apply foam insulation to paper

Holding the can upside down and with the nozzle just above the paper, gently press the trigger. Draw out a pattern of guts, the size and shape are entirely up to you.

Note, the slower you move the can the thicker the bead laid down will become. Also keep in mind this foam expands as it drys so keep the initial lines less than an inch thick.

You can see the expansion of the foam in the images above.

Step 4: Prime and apply black

Once the foam has dried spray with the grey primer. It's better to spray 1 or more thin layers than 1 heavy one.

After the primer has dried, spray paint all the creases, crevices, nooks, and crannys black.

Step 5: Spray 1st coating of red

Once the black has dried take the darker of the two reds your using and spray most of the unpainted foam. Overlapping with the black is fine just try not to completely cover the black.

Try to leave a few areas unpainted as well.
This is so creative! Great job!

Hey i have some questions about Great Stuff that is completely unrelated.

is there any spray i could use to make great stuff to not stick to plaster or some other surface? any advice would be great!

wd-40 would probably work, though I'm not sure if that would damage the plaster or not

alright thanks for your help
