An epoxy sealer is a protective coating made from a mixture of resin and hardener. It is commonly used to seal surfaces such as concrete, wood, and metal, providing a durable barrier against moisture, chemicals, and wear. This type of sealer is known for its strong adhesion and resistance to stains, making it ideal for both indoor and outdoor applications. When applied, an epoxy sealer creates a glossy finish that enhances the appearance of the surface while also extending its lifespan. It is often used in garages, basements, and industrial settings, where heavy traffic and exposure to harsh conditions are common.
