They work by filling the pores and capillaries of the concrete with a protective barrier, which prevents water and other substances from entering and causing damage. Penetrating sealers are a popular choice for driveways, as they do not change the appearance or texture of the concrete, and are effective for several years before needing to be reapplied.
Note that penetrating sealers do not provide protection against stains or oil spills, so additional measures may be necessary to protect your driveway in these cases.
Polyurethane sealers are a type of concrete sealer that provide a durable and long-lasting protective layer to your driveway. They are available in both solvent-based and water-based formulas and can be applied with a roller, sprayer or brush.
Polyurethane sealers are resistant to water, chemicals, and UV rays, making them ideal for use on concrete surfaces that are exposed to the elements. They also offer a glossy finish that enhances the appearance of your driveway.
While polyurethane sealers can be more expensive than other types of sealers, they offer superior protection and longevity, making them a good investment for your concrete driveway.
Epoxy sealers are a type of concrete sealer that can provide a durable and long-lasting finish to your driveway.
They consist of two parts, a resin and a hardener, which are mixed together before application. Epoxy sealers can be used to create a high-gloss finish that is resistant to chemicals, stains, and abrasions. They may not be the best choice for outdoor use, as they can yellow and degrade when exposed to UV rays.
Follow the manufacturer’s instructions for application and to ensure that the surface is clean and dry before applying the sealer.
