A spray or aerosol is a shower of very small droplets of a liquid or very fine particles of a solid suspended in the air. After a short while the droplets dissipate by falling or blowing away.
A foam is similar to a spray but of air or other gas droplets suspended in a liquid or other medium. Shaving cream, whipped cream, soap bubbles are a foam in a liquid medium. A solid foam can be a sponge or plastic insulation material. Another example of a foam in solid is bread. Yeast used in the production of bread grows and creates pockets of carbon dioxide (CO2) which form the pockets that make the bread soft.

Spray foam works as insulation due to a chemical reaction that occurs when the spray foam is introduced to oxygen in the air. Inside the can, there is no oxygen and the can forms an air tight seal. The oxygen that reacts with the spray foam causes the foam to expand from five to ten times its size, thus filling all cracks and crevices.

To bond foam to foam, spray Clearco 444 Adhesive Spray, or equivalent, on the both surfaces to be joined and allow to dry until tacky as directed on the product label.
