Weight vs Volume When Mixing

Spray foam material is packaged, sold and shipped on the basis of weight. Therefore, in order to figure the volume of a product packaged in the drum, converting the weight of the product within the drum into gallons is required. To do so, the specific gravity or weight per gallon of material is required information. There is likely to be a difference between manufactures, so confirm with the product supplier to provide this info or if a scale is available, weigh the container first. Specific Gravity and per gallon weight of the liquid for some manufactures are provided on the SDS or product data sheet (formerly MSDS).

4 Ways to Save Material

Material is a costly investment in any project and can easily change your profit margin if you’re not careful. Time has been a learning experience and our experts prepared the top four ways to save material and prevent waste on the job site and in storage.

1. Balance the chemical ratio: When applying spray foam, it’s important to keep your chemical ratio accurate based on the material supplier’s specifications. Is your foam not sticking to the substrate? Is it fishy smelling? These are all signs your ratio is off, requiring a second application and wasting additional material. The fishy smell is a result of the foam being resin rich, requiring a decrease in the “A” side.

Remove moisture from your drums

The “A” component, while in the drum, will react with atoms in the air resulting in the formation of crystal like skin structures. The “A” material should be sealed properly to limit the potential of these formations that if allowed to form will contaminate the liquid. Contamination may make the liquid impossible to process, requiring disposal and wasting of the product. Once the drum is opened, the air needed to replace the displacement of the “A” material being removed should be dry. This is achieved be either low pressure nitrogen being let in the drum as the material is displaced or filtered through a desiccant dryer.

Open Cell vs. Closed Cell

How to choose the right foam for your portable spray foam equipment

When determining which type of polyurethane spray foam insulation to install, careful consideration should be placed on which type of cell is appropriate for the application. SprayWorks portable spray foam equipment is designed to accommodate both open cell and closed cell foam insulation.
