Concrete Sealing & Hardening Treatment.
CONQOR SEAL - Water‐based, penetrating hydrogel sealer that delivers durable and hardened concrete.
WHAT IS CONQOR SEAL?
CONQOR SEAL is a concrete sealing & hardening treatment engineered for both new and existing concrete.
CONQOR SEAL is an advanced water‐based formula which penetrates the substrate to form a silica hydrogel that fills pore spaces. This reaction not only hardens the concrete and reduces dusting but also assists curing by retaining moisture for optimal hydration.
Ideal for industrial floors, warehouses, car parks, and data centres, CONQOR SEAL preserves the natural appearance of your concrete while extending its service life – even in high-traffic conditions.
CONQOR SEAL does not contribute to extra tyre squeal on car park floors, as typical with acrylic topical sealers.
The treatment penetrates past the reinforcing zone, providing protection for the reinforcing steel, and avoiding the risk of delamination.
