Asbestos Sealer

Water-Based Asbestos and Cement Sheet Sealer

Nutech Asbestos and cement sheet sealer is manufactured using the latest technology cross linking alkaline curing acrylic emulsions. The product gives improved adhesion and surface binding properties for top coating systems including NuFlex, Tileflex or NXT Cool Zone.

Nutech Asbestos Sealer has the following qualities:

  • Excellent adhesion to weathered and porous Asbestos surfaces
  • Ambient temperature cross-linking
  • Easy application by brush, roller or spray
  • Excellent chemical resistance
  • Trafficable surface
  • Weatherproofing performance
  • High resistance to mould and fungus
  • Economical prime coat

Applications & Features

Nutech Asbestos and cement sheet sealer is designed to penetrate and seal the surface of new and weathered Asbestos and cement sheet. Due to the alkaline curing functionality, greater bonding is achieved compared to standard acrylic and co-polymer emulsion sealers. When used externally a pigmented topcoat system should be applied such as Nuflex, Tileflex or NXT Cool Zone to obtain maximum UV resistance and durability.

Nutech Asbestos and cement sheet sealer is a saturation/penetration coating suitable for both porous and non-porous asbestos and masonry surfaces. Application of this sealer prevents dusting and deterioration of Asbestos sheeting protecting adjacent environments from the risk of Asbestos related health problems. It is a stable non-yellowing coating, which retains flexibility and strength. Surfaces treated with hypo roof cleaner and sealed with this product provide excellent resistance against lichen, moss bacteria and mould regrowth.

The product has undergone rigorous testing and special consideration has been given to ensure that the chemical composition and compatibility of Nutech Asbestos and cement sheet sealer is suitable for Australian conditions.


Application Guide

High pressure cleaning of asbestos surfaces or the use of mechanical equipment is not allowed by regulations. Unless the equipment is controlled and does not allow asbestos dust to become airborne and enter the atmosphere. Pre-treatment with Nutech Hypo or Nu-EcoSafe MossRid is recommended. Low pressure water washing only, is recommended to avoid asbestos dust becoming airborne. Application in cooler weather is recommended to ensure maximum penetration of Asbestos Sealer.

Application by airless spray, brush or roller to saturation point is required to maximise surface binding properties.

Safety Precautions

High pressure cleaning of asbestos surfaces is not allowed by regulations.
