>> Construction adhesive. Polyurethane foam adhesive is used to bond sheetrock, plywood and other construction material to minimize the use of mechanical fasteners and to speed up the construction process. It is widely used in sub-floor application and is also widely used in manufactured housing construction.

>> Pest block. Bugs, critters, rodents and other insects enter the house through gaps, cracks, crevices and holes. Specially formulated foam sealants like Great Stuff Pro Pestblock, Todol IPF Pest Foam, Pur Black Sealing Foam and DAP insulating foam sealant are designed to block pests out of the home by eliminating points of entry.

Specially formulated foam sealants blocks critters and bugs like spiders, ants and and rodents from entering the home through gaps, cracks and holes.

>> Agricultural uses. Foam sealants are used to seal holes for better insulation in poultry houses and to control lighting. It is typically used in conjunction with proprietary formulated two-component polyurethane spray foam like Ag-Tite .

>> Landscape formation. Sometimes referred to as Landscape foam or “Black Foam”. The foam is typically black in color to blend in the outdoors and to prevent it from UV deterioration. The landcape foam bonds to porous and non porous stone, rock, cement and other construction material such as wood. It is often used for adhering loose mortar in rock walls.

>> Koi pond construction. “Black foam” is also used in pond construction to bond rocks in waterfall construction and to channel water flow. It is safe for use around fish and plants

>> Crafts. Hobbyists use foam to make small models and when cured it is carved to desired shape. Some people use foam to make Halloween creatures and decorations. It is also used to create sculpted landscape for train models as well as building habitat landscaping for glass tanks used for exhibiting small reptiles.

>> Packaging. Foam sealants especially the softer foam formulation like Great Stuff Window & Door may be used as braces when shipping products to prevent movement. However, care must be taken to prevent foam from getting on the product to be shipped. Foam is typically sprayed in a plastic bag and placed next to the product to be shipped. When cured the foam will form around the shape of the product. Polyurethane foam requires moisture to cure. It is difficult to cure form when too much foam is applied.  For professional foam-in-place packaging, check out the yellow pages. The two component professional foam cures in one to two minutes and is designed for the purpose of creating cushioning for products with custom dimensions.

* For larger scale projects, a foam sealant and adhesive dispensing applicator or foam dispensing gun is helpful as it speeds up foaming application. It also saves foam as it can be reused up to 30 days.

* When foam is used outdoors, it must be painted to avoid degradation caused by exposure to UV light.
