Peneseal Pro RTU is a ready-to-use, spray-applied reactive penetrating sealer for exposed concrete. It reacts within the substrate to form a sub-surface gel that seals pores, capillaries and existing hairline cracks against water penetration.
The treatment is suited to concrete roofs, podium decks, bridge decks, terraces, traffic-bearing structures, runways and driveways exposed to weather and thermal stress. Its sub-surface action does not peel or scratch and does not affect the adhesion of subsequent compatible products.
Peneseal Pro RTU also improves resistance to water, chloride and sulfate ingress, chemical attack and carbonation when applied and water-cured in accordance with the TDS.
