# Finding a Workspace

Part of the Composite Materials Merit Badge Digital Resource Guide: [Introduction & Overview](https://merit-badge.university/merit-badges/composite-materials/guide/index.md)

*5. Building with Composites*

> **5b.** With your counselor's assistance, find an appropriate site where the projects can be safely completed under your counselor's supervision and/or the supervision of an adult approved by your counselor who is knowledgeable about composites.

You would not spray-paint in a closet or weld in a living room. Composites work has similar space requirements — the chemicals, fibers, and tools demand a workspace that is safe, ventilated, and set up for the job.

## What Makes a Good Composites Workspace?

### Ventilation — The Non-Negotiable

Resin fumes (especially styrene from polyester and amine vapor from epoxy hardeners) must be carried away from your breathing zone. A good workspace has:

- **Cross-ventilation** — at minimum, open windows or doors on two sides so air flows through the space rather than stagnating
- **Exhaust fan** — a box fan in a window blowing outward pulls fumes away from you. Position yourself between the fresh air source and the exhaust so clean air passes over your work.
- **Ideally, a dedicated fume extraction system** — professional shops use ducted ventilation hoods. If your counselor works in a professional shop, this is likely already in place.

Working outdoors solves the ventilation problem but introduces dust, bugs (which stick to wet resin), and weather variables. A covered patio or carport is a good compromise if indoor ventilation is limited.

> **Safety First!**
>
> Never work with resins in a closed, unventilated space — not a basement without windows, not an enclosed garage with the door shut, not a bedroom. Even with a respirator, you are still exposing your skin and eyes to fumes, and concentrations can build to dangerous levels quickly.

### Work Surfaces

Cover your work surface with disposable material — plastic sheeting, wax paper, or Tyvek. Resin will soak into and permanently bond to unprotected wood, concrete, or fabric surfaces. A flat table at a comfortable standing height is ideal. Working on the ground makes it hard to maintain good technique and puts your face closer to fumes.

### Cleanup and Waste

Your workspace needs:

- A **trash container** for contaminated gloves, mixing cups, and cured scraps
- **Paper towels** and a **solvent container** (sealed metal can) for tool cleanup
- A **sealed container for used solvent** — do not dump it down a drain
- Access to **soap and water** for skin decontamination (not solvent — remember [Req 1a](https://merit-badge.university/merit-badges/composite-materials/guide/req1a/))

### Temperature

Most resins cure best between 65°F and 85°F (18–29°C). Below 60°F, epoxy and polyester cure very slowly or incompletely. Above 90°F, pot life shortens dramatically — you may not have enough working time to finish your lay-up before the resin starts to gel.

## Where to Look for a Workspace

| Location | Pros | Cons |
|----------|------|------|
| **Counselor's shop** | Purpose-built, equipped, ventilated | Schedule coordination |
| **School shop/maker space** | Equipment available, supervised environment | May need special permission for chemical work |
| **Garage (door open)** | Convenient, tolerates mess | May lack ventilation without open door; temperature varies |
| **Covered patio/carport** | Excellent ventilation | Weather dependent, dust/insects |
| **Community maker space** | Tools and ventilation available | May have rules about chemicals |

> **Tip**
>
> If your counselor works in a professional composites shop, that is the best option. You will have proper ventilation, tools, and an expert watching your technique. Ask your counselor first — many are happy to host Scouts in their workspace.

## Setting Up Your Space

Before your first project session, set up the workspace completely. Mixing resin with sticky gloves while searching for scissors is a recipe for a messy, unsafe, and frustrating experience.

**Workspace Setup** — Prepare all of this before opening any resin

- [ ] Work surface covered with disposable plastic or wax paper
- [ ] All PPE laid out and accessible (gloves, glasses, respirator)
- [ ] Resin, hardener, and mixing supplies within arm's reach
- [ ] Fiber reinforcement pre-cut to size
- [ ] Scissors, rollers, and squeegees ready
- [ ] Trash container lined with a bag
- [ ] Paper towels in quantity
- [ ] Soap and water accessible for skin washing
- [ ] Fire extinguisher visible and reachable
- [ ] SDS sheets for all chemicals posted or available nearby
- [ ] Ventilation running (fan on, windows open)

Your workspace is ready and your projects are underway. When they are finished, you and your counselor will evaluate the results together.
