LithiSeal ZLi71 Concrete Sealer, LITHISEAL ZLi 71

First Component
Within (1) hour of application the 1st component sets up forming a temporary shield over the surface that stops moisture penetration from the top while protecting the treated material during the reactive chemical fusion process of the sealer.

Second Component
The 2nd component continues to penetrate, encapsulating tiny surface and interior particles, filling up voids and capillaries which significantly tightens and hardens the wear surface, creating an impermeable water barrier.

Third Component
The 3rd component, a nano material, penetrates deeper forming hard, insoluble structures as it goes, filling macro and micro spaces, solidifying the entire treated material into one solid mass. Permanent and irreversible protection is complete.

LithiSeal ZLi71

Commercial Grade Concrete Sealer, Hardener and Densifier

LithiSeal ZLi71 is a highly advanced lithium sealer specifically designed to treat a wide variety of substrates, including…

    • Architectural concrete
    • Splitface block
    • Stucco
    • Concrete block
    • Stone
    • Pavers
    • Exposed aggregate
    • Clay tile
    • Brick

LithiSeal ZLi71 incorporates a unique blend of lithium and silane/siloxane for resistance to chloride intrusion; all in a single application.

LithiSeal ZLi71 provides excellent water repellency to reduce cracking, spalling, chemical degradation, biological growth, efflorescence and dirt pickup, lengthening substrate life and reducing maintenance costs.


LITHISEAL ZLi 71 is a clear, solvent-free, odorless, VOC compliant, water-based environmentally safe-to-use salt barrier and dust proofer that seals, hardens and densifies concrete and masonry.


  • LITHISEAL ZLi 71 incorporates the sealing, hardening and alkali-silica reaction (ASR) preventing properties of lithium silicate with the chloride protection of silane/siloxane, all in a single, permanent application.
  • LITHISEAL ZLi 71 forms an effective chloride ion screen providing unmatched protection against water and water-carried salts that cause erosion, deterioration and corrosion.
  • LITHISEAL ZLi 71 can be used as an interior or exterior treatment for both horizontal and vertical concrete and masonry. It is perfect for parking garages, bridge decks, brick structures, historic restoration and integrally colored concrete.
  • LITHISEAL ZLi 71 helps prevent Alkali-Silica Reaction (ASR), a serious problem that occurs when the alkali in the large and fine aggregates reacts with the silica in the cement and with water to form an expansive gel, which can break concrete apart.
  • LITHISEAL ZLi 71 is vapor permeable to resist cracking, peeling and blistering. This lengthens substrate life and allows for greater structure strength over time.
  • LITHISEAL ZLi 71 protects gray and colored concrete from weathering and efflorescence thereby reducing maintenance, cleaning costs and repairs.
