Help with Penetrating Sealers

Unlike traditional sealers that leave a film on the top of concrete, penetrating sealers soak deeply into concrete and undergo a chemical reaction. That reaction creates a long lasting and effective barrier, preventing the absorption of water and deicing chemicals which damage concrete from the inside. Water and chemicals become destructive as they freeze and expand, and corrode the rebar inside concrete. Penetrating sealers block the pores and capillaries in concrete, providing maximum long-term protection.

Things to know…
  • Whether you live in a northern state that salts its roads during winter months, or states near the ocean, salt is quietly destroying your concrete. Over the years, salt migrates through concrete to the underlying structural steel, causing it to rust. As steel rusts it expands, and before you know it… POPS the concrete loose! This is the same process that creates potholes on highways.
  • Salt and deicing chemicals also allow concrete to absorb more water than it would on its own. More water means more expansion as it freezes, creating more spalling and “pop outs”.
  • Hardeners and densifiers are a type of chemical used to make concrete less porous, making it stronger and able to withstand greater loads, while reducing the “dusting” and maintenance requirements.
  • In environments which experience a drop in temperature below 32 degrees, freezing water is the biggest threat to concrete. When water freezes, it expands 9%, and this expansion is enough to destroy something as strong as a concrete driveway.
  • Concrete is a brittle substance, which crumbles over time and use. This wearing away, or "dusting" of concrete surfaces, creates a dirty atmosphere, which can be tedious work to maintain.
  • Water repellents
    • Water repellents are a type of penetrating sealer which is designed to shed water. By reducing the amount of water in concrete, the possibility of freeze-thaw damage is also reduced. You can even see them in action! If you put a drop of water on a concrete surface treated with ChemMasters water repellents, you will see the water bead, and stay at the surface.
  • Hardeners & Densifiers
    • Hardeners and densifiers are a type of chemical which is used to make concrete less porous. The less porous the concrete, the less dusting takes place, and the less maintenance needs to be done.

Is your concrete new?

Unique Patented Penetrating Cure & Seal

  • Silencure™: Available in high-VOC (Silencure), low-VOC (Silencure-A), and water-based (Silencure SRT) formulations. Silencure is a patented technology that cures concrete, applies a long-term penetrating silane sealer, and leaves a low gloss acrylic film. All in one step! Silencure is the “best” available protection for new concrete from damage caused by deicing chemicals, freeze/thaw cycling, and salt water. Silencure and Silencure-A are great choices for broom finished concrete, while Silencure SRT can be used on hard troweled and precast concrete as well. All Silencure products are designed to be used only on newly placed concrete. To learn more, click here. Silencure is available in 5-gallon and 55-gallon packages.

Your driveway, sidewalk or garage is… NOT new?
