How to Build a DIY Grim Reaper Halloween Prop: PVC Frame and Monster Mud Cloak
To build a DIY grim reaper, glue a PVC pipe frame with a cross fitting for the shoulders, shape the body with chicken wire, drape it in burlap, gauze or a gray sheet, then coat the cloth in monster mud, a mix of joint compound and paint, so it dries stiff. Mount it on a weighted base or a ground stake so it stands up outdoors.
A hooded reaper is the classic centerpiece of a graveyard, and you can build a life-size one from PVC, wire and fabric instead of buying a store prop. Most of the supplies are easy to shop for on Amazon or find at a hardware store. Stand it among tombstones in a graveyard scene and the whole yard looks watched. Below are two published builds so you can choose by height, materials and mounting.
Which grim reaper build should you choose?
| Build | Core materials | Best for | Notes from the source |
|---|---|---|---|
| PVC reaper with gauze cloak | 12 ft of PVC, elbows, cross fitting, chicken wire, gauze or gray sheet, foam head | A flowing, ghostly cloak and a custom pose | Two people help with the draping; cloth needs overnight to a few days to dry (PeaHen Pad) |
| 6.5-foot burlap reaper | 1.5-inch PVC, two 2×12 boards, gas pipe and flange, chicken wire, black burlap | A tall, sturdy figure with a fixed base | Does not collapse for storage, so it needs garage space (Halloween Addiction) |
What supplies do you need?
Which items you need depends on the build you pick. Here are the common ones, linked as tagged Amazon searches or catalogued products:
- PVC pipe, PVC elbows and cross fittings and PVC cement for the frame
- Chicken wire to shape the shoulders and body
- Black burlap, gauze cloth or a gray sheet for the cloak
- Joint compound and exterior paint to mix monster mud
- A foam head or reaper mask for the face
- An umbrella stand or flange and gas pipe for the base
- A hot glue gun for trim and details
- Color-changing LED strip lights to light the hood from below
How do you build the PVC frame?
- Cut and dry-fit. PeaHen Pad uses about 12 feet of 1 to 1.5 inch PVC with two 90-degree elbows for the shoulders and a cross fitting for the neck. Two optional 45-degree elbows help the arms hang naturally. Dry-fit everything in your chosen pose before gluing.
- Glue it. Join the pieces with PVC adhesive once you like the pose.
- Add the base post. Halloween Addiction secures a gas pipe flange to the center of two 2×12 boards, slips the PVC over the pipe, then drills and fastens it so the figure stays steady. PeaHen Pad uses an umbrella stand or a 6-foot PVC ground stake.
- Shape the body. Wrap chicken wire around the frame to build out the shoulders and chest. PeaHen Pad also adds foam pool noodles or pipe insulation for the arms.
Safety note: Wear gloves when cutting and bending chicken wire, and use eye protection and ventilation when cutting PVC or using PVC cement. Follow the label on your adhesive and paint.
How do you make the cloak and monster mud?
- Test the drape. Pin the cloth to the frame, cut a hole for the head and adjust the folds. PeaHen Pad says to use two people for this step.
- Mix monster mud. PeaHen Pad mixes 5 parts all-purpose joint compound to 1 part black paint, enough for three or four reapers from a 5-gallon batch. Halloween Addiction mixes drywall compound with gray exterior latex paint.
- Coat the cloth. Dip the gauze or burlap in the mud, drape it over the frame and shape the folds. Fray the ends of burlap for a tattered look.
- Let it dry. PeaHen Pad lists overnight and a few days for full drying, so start well ahead of Halloween.
- Seal it. PeaHen Pad uses a masonry water seal, and Halloween Addiction suggests an optional clear coat for outdoor use.
Add a foam head or mask under the hood. Our guide to how to corpse a skeleton shows a way to age a skull face.
How do you light and place a reaper?
- Light it from below. A small uplight or LED strip at the base makes the hood cast deep shadows.
- Add a lantern. Halloween Addiction wires a lantern with a red bulb to the extended arm, with an optional flicker circuit.
- Use low fog. A little ground mist hides the base. See how to get low-lying ground fog.
- Pair it with ghosts. A chicken wire ghost or two nearby builds a haunted group.
Frequently Asked Questions
How tall is a DIY grim reaper? Halloween Addiction’s build stands 6½ feet tall. PeaHen Pad’s depends on how you cut the PVC and which base you use.
What is monster mud? It is a mix of all-purpose joint compound and paint, applied to fabric so it dries stiff and holds its folds. PeaHen Pad uses a 5-to-1 ratio of compound to black paint.
Can a reaper stay outside? Both builds suggest sealing, with a water seal or a clear coat. Neither source gives a weather test, so check the prop after rain and wind.
How much does it cost? Neither source states a total. Price the PVC, wire, fabric, compound and base where you shop.
Can you store it? Halloween Addiction says the finished prop does not collapse and needs year-round garage space, so plan storage before you glue the frame.
