Polished Concrete Sealer
Coval Polished Concrete Sealer protects polished concrete and terrazzo without changing the DISTINCT, glossy sheen.
Coval PCS forms a covalent bond with the surface for an extremely hard barrier against food, acid, and oil stains, moisture, dirt, and graffiti damage. Use it in place of other sealers for enhanced, long-lasting shine and protection.
Single component and easily installed, cleaned, and reapplied in highly trafficked areas, Coval Polished Concrete Sealer delivers powerful, penetrating protection for polished concrete and Terrazzo.

Coval Polished Concrete Sealer penetrates the surface when applied with an acetone sprayer and white microfiber pad, forming a chemically resistant barrier to protect against floor damage.
Popular Polished Concrete Flooring
Polished concrete floors are in great demand in retail, restaurants, warehouses, exhibit spaces, and homes. Coval PCS provides an extremely hard surface for protection from acid-etching, stains, and wear.
Terrazzo Revived
Terrazzo that has been worn down and lost its shine can be polished, densified, and coated with Coval Polished Concrete Sealer to renew an old, tired floor, OR, to keep a new Terrazzo floor shiny and beautiful.
Concrete Overlays
All polished and densified concrete, including concrete overlays, can benefit from Coval PCS. An overlay applied directly to an existing concrete slab can last many years, especially when treated every few years with a penetrating sealer such as Coval PCS.
Frequently Asked Questions
Most polished concrete sealers either penetrate into the slab (hard to repair uniformly) or form a film on top (risk of peeling and scratching with traffic). Coval PCS creates a molecular bond that integrates with the concrete at the chemical level — it can’t peel, and damaged sections can be recoated without stripping.
Coval PCS can be applied to enhance or maintain the existing sheen level of polished concrete. Use the Matting Agent to achieve a matte or satin finish, or the UTC over the PCS for enhanced gloss.
Yes. Coval PCS has been successfully applied to major commercial installations, including the NRG Center in Houston, TX (terrazzo floor) and a 27,000 square foot commercial floor in Oklahoma.
Coval PCS dramatically reduces maintenance effort. Regular sweeping and mopping with a neutral cleaner is typically sufficient. The chemical resistance of the coating means that common cleaning agents won’t damage it.
Yes. Coval PCS has been applied to terrazzo surfaces with excellent results, as demonstrated on the NRG Center Houston project.
Application is fast relative to traditional multi-coat sealing systems. Coval is single-component and spray-applied, significantly reducing labor time. Contact your Coval representative for project-specific time estimates.
Coval contains less than 100g/L VOCs and no known Prop 65 carcinogens. Adequate ventilation during application is recommended, but the low VOC content makes it suitable for commercial spaces with appropriate application scheduling.
