Rather use the best waterproofing products that actually contain what they claim be. Not made in a garage with no real value.
Sika Blackseal Lastic and SikaLastic 560 are world leading brands and have been formulated by real scientists not made in a garage.
Are Rubber Paints/Sealers really contain rubber?
No, most paints labeled "rubber" are not made with actual rubber but with synthetic polymers, such as acrylic, that mimic the properties of rubber. These paints are called "rubber" or "elastomeric" because they form a highly elastic, flexible, and durable film that can expand and contract with the surface.
Synthetic rubber vs. natural rubber: Instead of natural rubber, these paints use synthetic polymers like acrylics, which are then formulated to provide the same flexible, waterproof, and durable qualities.
Liquid rubber: A specific type of product that is literally a liquid rubber coating, but often still uses synthetic rubber compounds and is applied as a thick liquid to form a seamless, flexible membrane.
Key characteristics: This "rubber" paint is known for its ability to resist cracking and peeling, especially on surfaces that experience movement or weather changes, making it suitable for roofs, walls, and other exterior applications.
