Pentra-Shield® is an exterior concrete and masonry Nano-LithiumⓇ densifier that dramatically increases protection of treated surfaces from freeze-thaw, scaling and spalling damage. This specialty treatment strengthens exposed concrete like parking structures, sidewalks and driveways to minimize damage caused by winter weather. Pentra-Shield® is a penetrating, reactive, breathable solution that reduces moisture absorption and leaves no surface film or discoloration. This silicon reactive, lithium-based solution (SiRE)™ is VOC compliant and easy to apply.
Surfaces protected with Pentra-Shield® have unique protective benefits that include increased strength, durability, and repellency. This treatment also provides protection against efflorescence and water intrusion. It may be applied to both newly-placed concrete and existing concrete to protect against damage from the elements.
• Protects against freeze-thaw cycles and de-icing chemicals
• Reduces scaling and spalling
• No surface film to peel or wear off
• Does not alter the coefficient of friction of the surface
• Will not discolor or change the substrate surface appearance
• Reduces porosity and increases strength and durability
• VOC compliant, may contribute to LEED points (IEQ credit)
