Concrete Curing & Retarders

These membranes are formulated with inert hydrocarbon resins which give films with excellent water retention efficiency in excess of 75% and 90% respectively, complying with ASTM C309.66 and HA Spec. clause 1027. Available in clear, white and with aluminium flake pigment, to give maximum solar reflection.

Designed for coating dowel bars in concrete roads, airfield joints and floor sections and is based on bitumen having a penetration between 100 and 200, blended with hydrocarbon solvents. The consistency of the material is such that once it has dried and the concrete cast, free movement between the bar and the surrounding concrete is achieved.

Top Face Retarder, water-based spray-applied retarder designed to expose aggregate on horizontal surfaces, biodegradable/environmentally friendly.

Eco-Tard Liquid MF is an aqueous biodegradable pigmented retarder designed to be applied to formwork surfaces to produce an exposed aggregate surface which gives an excellent key for subsequent concreting or provides an alternative exposed finish. It is ideal for construction joints and rendering applications.

High performance heavy duty acrylic sealer. Hardseal is a low viscosity, penetrating colourless sealer and is based on a carefully sourced blend of chemicals. It hardens, seals and cures all in one. Also offers 90% curing efficiency.
