After you have safely cut down the excess foam, consider using sandpaper to smooth the area or remove additional foam material. You will want to use coarse sandpaper on the surface and apply lightly for best results. Consider 80 to 120-grit paper for smoothing. The goal is to make the area smooth without removing foam below the surface level. 3. Remove Dust and Debris From Expanding Foam Surface Adding additional coats of paint is important for both appearance and durability. Multiple coats will help to properly seal the foam, especially for outdoor applications that are subject to weathering. Once you have allowed for the first coat of paint to dry, you can add another thin layer. For full coverage, 2 to 3 coats with acrylic and latex paints is recommended.

If desired, you can also add a seal or varnish on top of your acrylic or latex paints. Acrylics typically use varnish to seal, while latex paints don’t usually add a sealant. You can add a clear topcoat to latex paints for additional protection and a glossy finish. GREAT STUFF™ Outdoor Insulating Foam Sealant is a ready-to-use, insulating foam sealant—specifically formulated for both indoor and outdoor use.* This multipurpose formulation expands up to 1 inch to take the shape of gaps, creating a long-lasting, airtight and water-resistant seal around the home, and in hunting blinds, fishing shanties, cabins, cottages, storage and other outdoor applications As a general rule of thumb, you will want to keep expanding foam away from power sources and any flammable areas. This will help to prevent fire and other chemical reactions. The paints themselves are not flammable as they are water-based, and latex is not a highly flammable substance.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. Paint choice: Some acrylic paints are designed to be faster drying than others. You can choose fast-drying paints if needed. This may impact the quality and characteristics of the paint. You can find water-based acrylics and latex paints in both spray paint and canned paint forms. All of the application methods are compatible with these types of paint. Try to use a flat paint as ones that are much glossier will point out imperfections and bumps much more easily. 5. Apply First Coat of Paint to Expanding Foam We are currently using Royal Mail Parcelforce and DPD as our delivery providers, all small items will be delivered by Royal Mail, these can take up to three working days to reach you. While expanding foam has many of the useful applications mentioned above, it should not be used everywhere. Keeping both the chemicals in the expanding foam and the paint away from dangerous areas will prevent accidents and explosions.

Great Stuff™ Insulating Foam Sealant: Save Money and Improve

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. Where Should You Not Use Painted Expanding Foam? Great Stuff™ and Great Stuff Pro™ products can be used in a variety of interior and exterior applications, most commonly in air sealing and home retrofit applications. Most common application include: Great Stuff ™ cans featuring the straw tube applicator will seal shut if left to sit for more than 2 hours after its last use. Too close to light fixtures: The close proximity of the foam and heat from the lighting could pose risks related to fire. Expanding foam is particularly flammable while being dispensed, so make sure that there are no heat or fire sources in any application. 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.

Keep dry: While moisture and humidity will help the expanding foam dry faster, it is not your friend for drying paint. Moisture will dry the paint at a much slower rate or result in uneven texture. To avoid this, keep windows and doors open or use a dehumidifier near the area. Shake vigorously for a minimum of 60 seconds. If the can sputters, simply shake the can while held upside down. It works to seal, fill, bond and insulate with excellent strength thanks to it's semi-rigid cellular structure.
