Terrazo Sealers

Concrete and Terrazo surfaces may be sealed using solutions of high durability, thermoplastic acrylic polymers. The sealer helps to prevent the ingress of oil, grease, fats, acids and alkalis as well as reducing the tendency of the surface to dust or flake. 

A sealer is produced simply by reducing a suitable acrylic to around 20% volume solids using an aromatic hydrocarbon solvent such as Shellsol A (Shell) or Solvesso 100 (Esso). Single coats of these sealers do not offer sufficient protection to prevent caibonation of the concrete or chloride ion attack from road salt. 

Thermoplastic acrylic resins are available from a number of suppliers, for example a) Polar solvent soluble
