hardseal certificazioni


Supershield Hardseal is a crystalline, one-component, transparent, water-based hardener, sealer and dustproof product for concrete floorings.

Hardseal hardens the mass of concrete, strengthening and protecting it from deterioration, oil, grease and other contaminants; it neutralizes alkalis and improves adhesion for further coatings. The product is non-toxic and contains no volatile organic compounds (VOC). It is applied by sprinkling on the surface to be treated and washing after with water.
Hardseal, diluted 1 to 7 and applied on fresh concrete, performs as an anti-evaporating agent, allowing the concrete to cure properly and avoiding shrinkage cracks.

It is designed to be applied in a single coat or as final coating on Supershield products such as Crystalspray, Vaporstop, Hardseal, Admix.

Use: concrete floors of industrial warehouses, depots, hangars.

Dosage: 1 litre of product per 5/7 m2, spray on clean and dry surface.
