Description

Contite Seal AC is a cementitious crystalline waterproofing treatment designed to protect concrete against water penetration. When applied to a properly prepared, damp concrete surface, it penetrates the substrate and reacts to form insoluble crystalline structures within the pores and capillaries, helping to reduce permeability and provide long-term waterproofing protection.

It is suitable for concrete slabs, basements, water-retaining structures, construction joints and other concrete surfaces requiring protection against water ingress.
