Petrokem Deep Seal 20 is a two-component epoxy coating especially formulated as a surface primer and floor hardener for concrete sealer applications. The product can be applied on a dry or wet substrate and has exceptionally low viscosity which enables it to seep through concrete / cement-plaster surfaces due to surface porosity. Once fully cured it acts as a concrete densifier and a partial barrier against the intrusion of water and other liquids. Deep seal 20 is available in a range of colours as well as a clear coating and can be used as a surface primer for concrete, cement plaster and wood surfaces. Once correctly applied the coating provides long lasting protection attributed to its superior adhesion and high chemical resistance.
