Great Stuff foam can be used as an adhesive for delamination repairs
Great Stuff expanding foam is a polyurethane-based insulating foam sealant that fills, air-seals, and insulates small gaps (up to 1 inch) inside or outside. It is commonly used to fill gaps and cracks, providing good insulation and sealing properties. It is also used for delamination repairs.
Great Stuff expanding foam can be an excellent adhesive for delamination repairs if clamped properly. Users have reported success in repairing large delaminated areas on Class C cabovers using expanding foam as an adhesive. The process involves wearing disposable nitrile gloves, applying the expanding foam to one surface, and then pressing and misting the second surface to ensure complete coverage.
It is important to note that expanding foam can be messy and difficult to control. Users recommend wearing gloves and protective clothing to avoid sticky residue on the skin and clothing. Additionally, the one-time use nature of the product can lead to waste as leftover foam in the can tends to clog the nozzle.
When using Great Stuff expanding foam for delamination repairs, it is essential to follow the manufacturer's instructions and take the necessary safety precautions. The foam should be applied in a well-ventilated area, and users should avoid contact with skin and eyes. It is also important to note that expanding foam may not adhere to all surfaces, and proper clamping is necessary to prevent the foam from expanding freely, which can make it fragile.
Overall, Great Stuff expanding foam can be a useful and effective adhesive for delamination repairs when used correctly and with the necessary precautions.

It can be used to glue Styrofoam together
Great Stuff is an expanding foam that can be used to glue Styrofoam together. It is a versatile adhesive that works well for this purpose and is preferred by many over older methods.
To use Great Stuff to glue Styrofoam together, you should first cut the Styrofoam to size and prepare the two surfaces you are gluing together. Set them on a drop cloth with plenty of extra space, as the spray is sensitive and easily triggered. Once you start spraying, you will likely have to use the whole can, so it is best to plan to use it all in one sitting.
Spray the Great Stuff all over the top surface of the Styrofoam, which will sit at the bottom while it cures. Lay the next layer of Styrofoam on top and weigh it down with a piece of plywood and stage weights. It is recommended to glue one layer at a time, waiting an hour or so between layers. The curing time will depend on the weather, but an hour should be enough for the layer to be close to cured.
You can also use Great Stuff to hook foam to wood. However, it is important to take precautions when using this product, as the fumes can be harmful. It is recommended to wear gloves, long sleeves, eye protection, long pants, and a stocking cap. You should also work in a well-ventilated area or outdoors.

When using Great Stuff foam, it is recommended to wear protective clothing, such as gloves, safety glasses, and clothing that covers your skin and hair.
