Waterproof sealants and waterproof coatings are both used prevent water from penetrating surfaces and causing damage. However, there are some key differences:
Applicaiton: Waterproof selants are typically applied as a viscous liquid that dries to form a viscous liquid that dries to form a flexible, rubbery seal. They are often used to fill gaps and joints in surfaces such as roofs, walls, and floors. On the other hand, waterproof coatings are usually applied as a thick, paint-like substance that is apread evenly over a surface.
Durability: Waterproof sealants are generally more durable than waterproof coatings, as they can withstand more movement and deformation without cracking or peeling. However, they may not provide as uniform of a surface finish as waterproof coatings, which can be more aesthetically pleasing.
Purpose: Waterproof sealants are often used to fill gaps and cracks in surfaces to prevent water from entering. They are typically used in areas where there is a high likelihood of movement or deformation, such as around windows and doors. Waterproof coatings, on the other hand, are often used to protect surfaces from water damage, such as on roofs, decks, and foundations.
You can apply the waterproof sealant then use roof coating as cover to get a strong waterproof protection.
Overall, both waterproof sealants and waterproof coatings can be effective at preventing water damage, but the choice between the two depends on the specific application and the surface being protected.
