Pentra-Shield is a clear, penetrating, breathable, surface-applied liquid that strengthens, protects and hardens concrete and masonry surfaces. Pentra- Shield Anti-scale treatment helps protect concrete sidewalks, driveways and other concrete and masonry surfaces from freeze-thaw damage caused by moisture saturation within the pore structure of substrates. Scaling begins with the first freeze-thaw cycle and will continue through successive winter seasons resulting in repeated loss of the concrete surface, eventually leading to spalling, pop-outs and ultimately failure if left untreated.
Surfaces protected with Pentra-Shield have unique protective benefits that include increased strength and durability, reduced the porosity and increased hydrophobic characteristics which provide protection against alkaline degradation, water intrusion and salt brine crystallization (sub-florescence). It may be applied on both newly placed concrete and existing concrete to protect it against damage from the elements.
