SAFETY DATA SHEET

The Smart Dispenser™ from the Great Stuff™ brand is a game-changing, industry best dispenser for one component can sealants. It works to seal, fill, bond and insulate with excellent strength thanks to it’s semi-rigid cellular structure. Ventilation: Exposure to air and good ventilation will allow for faster drying. Consider using a fan if the area does not naturally have this exposure. Most foams are also heat resistant, so you can apply heat for faster paint drying time.Use expanding foam to fill the box below, around, and above the item. Work slowly, and wait for the foam to expand before adding more.

Gaps and Cracks with Smart Dispenser™ - DuPont

The low-expansion foam dries to the touch in just 15 minutes and can be trimmed after 1 hour. It adheres to wood, metal, masonry, glass, and most plastics, forming a water-resistant seal once it has cured. The foam takes about 12 hours to fully cure, at which point it can be sanded, painted, or stained. After you’ve fully prepared the cured expanding foam, it’s time to look at starting the painting process. Choosing an appropriate paint will depend on the location of the foam, whether that be interior or exterior applications. Exterior paints will be more durable for varying weather conditions. The composition of the paint also matters, so it doesn’t compromise the foam. This Foam-iT! product is specially designed for pouring into molds used in prop-making and arts and crafts. It expands to 10 times its normal volume, making it great for a wide range of project sizes, and cures in just 6 minutes. Although you do need to mix it, the 1:1 ratio makes this step easy for anyone to figure out. Its beige color also allows you to mix your own pigments in and adjust the color to your liking. This fire-resistant expanding foam fills gaps greater than 1 inch in width, creating an airtight, water-resistant seal. It dries in 15 minutes; when it fully cures in 4 hours, it can be sanded, painted, or stained. The low expansion foam repels insects and other pests, protecting the home from infestations.

Delivery Policy

Be Patient: Your expanding foam may also have imperfections on the surface, especially if you did not fully sand. When applying a heavy first coat, it will be difficult to fully dry and will result in a ‘pooled look’ once it does dry. Patience on the first coat will make it easier to add more layers and give you the full coverage you are looking for. Skin of cured foam can discolor if exposed to natural light. Paint or coat foam for the best results. Smooth strokes: Try to smoothly cut along the surface to disrupt the filled area as little as possible. This will also make it easier to finish with sandpaper. Serrated edges on knives can help to cut through the foam more easily. Great Stuff™ cans featuring the Smart Dispenser™ may be reused up to 30 days with the straw left attached to the canister, just clean the tip after your first use. Painting your expanded foam will not only help to add an additional layer of sealant, but it will make foam applications less obvious when blended in.

How We Evaluated Yes, some expanding foam is designed to be waterproof. Certain products are even made specifically for building ponds, fountains, and other outdoor water features. For added convenience, those waterproof expanding foams are also made to withstand harmful UV rays to ensure maximum longevity and durability. Q. Where should you not use an expanding foam? Cut close to the surface: You will want to trim closely along the surface of the covered area to remove as much excess foam as possible without cutting into the filled section. The type (and sharpness) of knife to use will be based on the strength of the foam.
