Foam is a popular material for crafting due to its lightweight and low cost, but it requires hardening treatment to prevent damage during transportation and preservation. One of the best options to protect foam creations is a hard-shell coat called Polyurea, which provides a long-lasting protection that ensures your foam creation remains safe and beautiful for years to come.
Polyurea is a coating that can be applied to any foam project, from signs, letters, logos, and props to prototypes, crown moldings, concrete molds, and more. It protects the foam shape from weather, water, sun, humidity, age, and break damage. The Polyurea coating combines high flexibility and durability with high hardness and is fast-drying. It can be sanded to a smooth finish and can then be painted with any type of paint, such as water-based paint like latex, any oil-based paint, or automotive paint.
Spraying Polyurea material is widely used in the foam sculpture industry, including skin protection for wedding film and television props, waterproofing and protection of theme parks, water parks, and various riding facilities, stage sets, advertising exhibits, antique building protection, and more.
Polyurea has many advantages, such as high curing speed, protection from conditions of humidity, heat, cold, and sun, extreme abrasion resistance, chemical resistance, good adhesion to the material it is sprayed on, and unlimited application thickness. The coating is non-toxic and completely safe for use. Any type of foam can be sprayed, from rigid foam to soft polyurethane foam. When spraying foam with this coating, a smooth or textured finish can be applied according to the customer’s needs.
Without coating, foam is exposed to the dangers of being damaged by sun, wind, humidity, and corrosion or being broken. For instance, a foam sign can break anywhere between the packaging, shipping, handling, and installation phases. However, with Polyurea coating, the sign thrown to the ground or tossed from one place to another will not break.
For large foam projects, a large spray system is recommended, such as the Graco-100. It is the same spray gun used to spray insulation on roofs. It is a heavy-duty gun that you will have to clean right after you finish using it, or else the material will clog inside, preventing you from using it again. For smaller foam shapes, you can hand-brush it or use a small spray gun with cartridges.
After applying the Polyurea coating, the coated foam can be sanded to any desirable finish, painted, and even bonded to a surface, such as plywood. The coating provides a long-lasting protection that ensures your foam creation remains safe and beautiful for years to come.
In conclusion, Polyurea is a recommended hard-shell coating for foam creations, providing protection from weather, water, sun, and humidity, and combining high flexibility and durability with high hardness. It dries quickly, can be sanded to a smooth finish, and can be painted with any type of paint. Polyurea is non-toxic, can be sprayed on any foam project, and has many advantages, including high curing speed, extreme abrasion resistance, chemical resistance, good adhesion, and unlimited application thickness. A large spray system is recommended for larger projects, while smaller foam shapes can be hand-brushed or sprayed with a small spray gun with cartridges. Foam sculpture is a popular material for crafts due to its lightweight and low cost, but it requires hardening treatment to prevent damage during transportation and preservation. Polyurea protective coating is the best option available in the market and highly recommended by professionals.
