A penetrating concrete sealer is a protective liquid that soaks into the pores of concrete rather than forming a surface film. It chemically reacts within the concrete to create a water-repellent barrier that helps protect against moisture, salt damage, freeze-thaw cycles, stains, and deterioration.

It’s typically used on exterior concrete such as driveways, sidewalks, patios, garage floors, pool decks, and parking structures. It works best on porous concrete surfaces (like broom-finished)

An acrylic concrete sealer is a film-forming protective coating that sits on top of the concrete surface rather than soaking in. It creates a thin, clear (or sometimes tinted) layer that enhances color, adds a satin or glossy finish, and protects against water, stains, and light abrasion.

It’s commonly used on decorative and exterior concrete such as stamped concrete, colored concrete, exposed aggregate, patios, and walkways
