Paver sealer is a protective coating applied to pavers, which are often used in driveways, patios, and walkways. This sealer helps to enhance the appearance of the pavers by providing a glossy finish and can also prevent stains from oil, dirt, and other substances. In addition to aesthetic benefits, paver sealers protect against weather damage, such as fading from sunlight and erosion from rain. Regular application of a paver sealer can extend the lifespan of the pavers, making them more durable and easier to maintain over time.
