Exposed Aggregate Sealers/Sealants


Exposed aggregate is one of the most popular styles of decorative concrete and W-SEAL can provide superior quality sealers/sealants to protect and decorate your exposed aggregate concrete. The same sealers/sealants used at institutions such as Cal Poly, Easton Town Center, Hilton, Marriot and Westin are also available for your driveway, patio, or sidewalk. There are two main categories of sealers/sealants – penetrating sealers/sealants and topical coatings (for more information see below).

Exposed Aggregate Sealers/Sealants
Broom finish concrete is the predominant building material for high priority exterior horizontal surfaces such as roads, bridge decks, parking decks, driveways and sidewalks. But, even the best concrete is vulnerable to scaling if it becomes saturated during harsh winter weather (Concrete Technology Forum 2009). The same products used by Honda, NASA, the Ohio DOT and the Indiana DOT can also protect your broom finish concrete. There are two main categories of driveway sealers/sealants – penetrating sealers/sealants and topical coatings (more information below).

Broom Finished Concrete Sealer Basics
Penetrating Sealers/Sealants soak into porous concrete and masonry and create a permanent chemical reaction. They offer a flat appearance and protection that will only wear away if the substrate itself wears away below the level of sealer penetration. Penetrating sealers/sealants require porous masonry to be effective. All W-SEAL penetrating sealers/sealants will permanently bond within porous concrete and masonry to strengthen the surface, repel water (ice), oil, salt, and mold and form a moisture resistant barrier that helps prevent surface defects such as chipping, scaling, spalling and cracking, increase stain resistance and ease of cleaning, and block efflorescence with a flat appearance that does not affect traction and is breathable. Application is with pump sprayer or roller.

Topical Coatings are applied on top of concrete and masonry and can offer protection with color enhancement and wet look or gloss finish. In addition to the topical coatings listed below we offer topical coatings in gloss or matte finish, clear, translucent color, opaque color and with enhanced capabilities to resist oil, grease, gasoline, salt, urine and other harsh contaminants.
