What is the purpose of using sealants after painting?

Using sealants after painting primarily enhances durability and protects the finish. Sealants create a protective barrier over the paint surface, helping to defend it against environmental factors such as moisture, UV rays, dirt, and chemicals. This added layer of protection can significantly extend the lifespan of the paint job and maintain its appearance over time.

While sealants might have some aesthetic benefits, such as providing a glossy finish, their primary function is to enhance the durability of the paint. They prevent peeling, chipping, and other forms of wear that often occur due to exposure to elements. This characteristic makes them particularly valuable for surfaces that encounter frequent use or harsh conditions, ensuring that the underlying paint remains intact and vibrant for a longer period.
