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…
  • 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.
  • 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”.
  • Salt and deicing chemicals create artificial freeze/thaw cycles as they melt ice and snow, and it later re-freezes. Each freeze/thaw cycle damages concrete as the freezing water expands.
  • Hardeners and densifiers penetrate into concrete and undergo a chemical reaction to make interior concrete less porous, making it stronger and able to withstand greater loads, while reducing the ‚Äúdusting and maintenance requirements. ChemMasters makes a variety of hardner/densifiers including Chemisil, Chemisil Plus and Chemisil Plus Li.
  • Although not exposed to freeze/thaw cycles and weathering, interior concrete is often subject to abrasion, wear and dusting. A suitable treatment or coating can extend the life of interior concrete, make it easier to clean and less prone to dusting.
  • Penetrating Sealers
    • Penetrating sealers undergo a chemical reaction within concrete to form silicone, creating a concrete surface that repels liquid water but allows water vapor to escape. Making concrete less absorptive reduces damage caused by freeze/thaw cycles and deicing chemicals. SpallGuard WB-10 is a low-VOC water-based penetrating silane modified siloxane sealer. Aquanil Plus 40 is a high-VOC solvent-based silane sealer. Aquanil Plus 40-A and Aquanil Plus 100 are low-VOC solvent-based silane sealers.
  • Hardeners & Densifiers
    • Hardeners and densifiers undergo a chemical reaction within concrete to form more concrete paste, making the surface of interior concrete harder, denser, stronger, less prone to dusting and easier to clean. ChemMasters makes a variety of hardner/densifiers including Chemisil, Chemisil Plus and Chemisil Plus Li.

Solvent based:

  • Strengths
    • Able to be used in colder temperatures (down to 40 degrees Fahrenheit).
  • Weaknesses
    • Strong solvent odor
    • Solvents can damage landscaping

Water-based:

  • Strengths
    • Low-odor
    • Landscape friendly
  • Weaknesses
    • Requires higher temperatures for use (50 degrees and rising).

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 silicone barrier, preventing the absorption of water and deicing chemicals which damage concrete from the inside.

  • Penetrating sealers do not darken or change the appearance of concrete or masonry
  • Penetrating sealers are more effective protection against damage from freeze/thaw cycles and deicing chemicals
  • Penetrating sealers are easier to apply
  • Penetrating sealers last longer
  • Aquanil Plus 40 is a high-VOC solvent-based silane sealer. Aquanil Plus 40-A and Aquanil Plus 100 are low-VOC solvent-based silane sealers.
Product Recommendations for…

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.
