What is a Spray Foam Rig?

A spray foam rig refers to the professional equipment used to apply spray polyurethane foam insulation. The main components of a basic rig include:

• Spray foam machine – This is the core of the rig, combining and heating chemical components before spraying foam through the hose. Machines vary based on output rate and pressure capability.
• Transfer pumps – Pump heated chemical components from drums into the spray foam machine.
• Proportioner – Ensures the two chemical components are mixed at the right ratio before entering the spray foam machine.
• Heated hoses – Carry heated chemical components from the proportioner to the spray gun.
• Spray gun – Applies the spray foam directly on the job site. Different tips can adjust spray patterns.
• Air compressor – Provides air pressure to push chemicals through hoses to the spray gun.

These components work together to produce high-quality polyurethane foam for insulation applications. Larger rigs have higher output rates for increased productivity. Additional features like a generator, climate controls, and onboard foam tanks may also increase costs.

Frequently Asked Questions

How do you clean a spray foam rig?

It’s important to thoroughly clean your spray foam rig’s components after each use. Start by flushing the chemical drums, tanks, pumps and hoses with a cleaning solvent like acetone or MEK.

Remove and clean filters, gaskets and spray tips. Wipe down the exterior of components. Periodically do a deep cleaning by disconnecting hoses and fully cleaning the rig’s internal parts. Proper cleaning removes built-up chemicals and debris, ensuring optimal performance.

How long does it take for spray foam to dry?

On average, spray polyurethane foam takes 2-4 hours to fully cure and dry after application. Initial tack-free drying happens within 10-20 minutes, allowing you to apply additional passes of foam.

Full curing and drying depends on foam thickness, temperature, and humidity levels. Thicker foam applications may take up to 24 hours to fully cure throughout. Improper drying conditions can lead to surface cracking or improper curing.

How much spray foam do I need?

The amount of spray foam needed depends on the specific area being insulated. As a general estimate, one set of foam chemicals (A and B components) expands to cover 30-40 board feet of area at 1” thickness. So, for a 500 square foot attic at 1” thickness, you would need 12-15 sets of foam chemicals.

The foam’s expansion rate and your coverage rate determine quantities needed. Carefully evaluate each job and have surplus supplies on hand to ensure you spray the full area. Applying too little foam requires return trips and displeased customers.
