QL Nano Lithium Hard

Hardener, sealant, water-repellent, thickener, consolidating and protective

A hardening, anti-dust sealant and chemical thickener with lithium silicates for industrial flooring and surfaces in cement conglomerate in general, already cured and compact. Penetrates and seals concrete via chemical reaction, forming a transparent, durable, extremely hard, inorganic, breathable and abrasion-resistant surface. Excellent for concrete floors requiring long term protection against wear, exposure to unfavourable conditions, humidity, dirt build up, alkalinity and efflorescence (salt residue).

    QL Nano Lithium Hard

    QL Nano Lithium Hard deeply penetrates the capillary pores of the concrete, reacting chemically with the free lime to form a permanent and insoluble bond with the concrete. It creates a protective surface layer, which is breathable, thick and resistant to abrasion. It provides a stronger finish, which is impenetrable and pleasant from an aesthetic point of view (smooth-polished) capable of resisting dust, stains and wear. It reduces maintenance intervention and cleaning and repair costs.
    Fields of application
    Hardening, sealing, consolidating and dust-proof treatment of industrial floors and screeds in concrete, both old and new, both grey and coloured.
    Allowed supports
    Floor screed
    Preparation of supports
    The application surfaces should be clean, free of containment, inconsistent and incoherent parts, dust, etc., conveniently saturated with water to reach the "saturated to dry surface" condition.
    Mode of use
    Apply QL Nano Lithium Hard using a sprayer, roller or brush on the existing concrete surfaces. Always check the surfaces of the concrete are suitable and capable of offering the desired results. Before inspecting and approving the desired application, leave the surface to dry perfectly. The application time on the hardened support should be 24 hours at least in the summer time. 4 - 7 days recommended for the rest of the year.

    QL Nano Lithium Hard can be applied on the concrete surfaces when immediately created after the last finish with the trowel. Carefully clean the substrate, eliminating all the foreign materials such as non-stick products, hardeners, oil, dust, construction efflorescence, gypsum wall residue etc. Use an airless sprayer or type HVLP to apply QL Nano Lithium Hard, in such a way to form a regular, even, compact and polished layer, ensuring total saturation of the surface. Apply a quantity of QL Nano Lithium Hard sufficient to keep the surface wet for 20 minutes. Leave the surfaces to dry (generally for 1 or 2 hours). Proceed by applying a hardening agent according to the standard ASTM C 309.

    - Carefully clean the substrate, eliminating all the foreign materials such as non-stick products, hardeners, oil, dust, construction efflorescence, gypsum wall residue, etc. Before proceeding, ensure the surface is dry.
    - Use a low pressure sprayer to apply QL Nano Lithium Hard in such a way to saturate the surface.
    - Distribute QL Nano Lithium Hard on the surface using an automatic floor washer or a hard brush to facilitate penetration.
    - Leave the QL Nano Lithium Hard to act for 20-30 minutes.
    - Keep the surface wet with QL Nano Lithium Hard for 20 - 30 minutes (if necessary, add other product).
    - Remove the QL Nano Lithium Hard residue with clean water.
    - Leave the surface to dry.
