Spray Foam Check List

Your shopping cart includes at least one Low Pressure Spray Polyurethane Foam (SPF) kit. Below are a few basic requirements to help ensure a safe and positive experience when using any SPF kit. These requirements apply to all the different brands of disposable SPF kits on the market.

Please read and understand each requirement listed below. If you have any questions or concerns, please give us a call at (512) 432-5138.

Operating Instructions – Please read through the manufacturer’s operating instructions prior to using any SPF kit. Download Product Literature

Temperature – All SPF kits need to be conditioned to the proper temperature prior to use. Click here for tips on maintaining proper temperature.

Closed Cell: 75°F – 85°F
Open Cell: 85°F – 95°F

Shake Well – All SPF kits need to be “shaken well” prior to use. Small Kits – Shake the whole box for at least 2 minutes. Large Kits – Remove each tank from its box and roll back and forth on the ground for at least 2 minutes.

Test Shot – A small test sample should be sprayed prior to using the kit in the final application. A test shot is important to help ensure any potential issues are addressed prior to spraying the kit.

“30 second rule” – Whenever you stop spraying for 30 seconds or more, you will need to replace the nozzle. Failure to do so may result in damage to the gun.

Upright Position – The tanks must remain in the upright position (valve at the top) while spraying foam. Placing each tank in its box will help to keep it upright.

Spray Technique – When spraying begins, make sure you are holding the gun perpendicular (a 90° angle) to the substrate. For best results, maintain a distance between 12 to 18 inches from nozzle tip to substrate. ; Spraying with the gun more than 18″ from the substrate will result in a higher density foam and an overall lower board foot yield from the kit.

Safety Equipment – Personal Protective Equipment (PPE) is required when spraying foam. Click the chart below for an example.
