  L&M Cure™

L&M Cure™ is a VOC-compliant, ready-to-use, non-residual concrete curing agent that penetrates surfaces to cure concrete from within. It is a water-based, clear, sprayable liquid that offers residual-free performance. L&M Cure™ is non-staining, penetrating curing compound over which toppings can be later applied.

L&M Cure™ is odor free and is ideal in enclosed vented areas where odor-free products are essential, such as tunnels and chimneys. L&M Cure™ can be easily applied to both vertical and horizontal surfaces. Drying time is a maximum of 4 hours and penetration up to 1/8".

  Sonosil®

Sonosil® is a clear water-soluble, sprayable, inorganic, silicate base compound for surface application to cure, harden, and dustproof interior or exterior fresh concrete floors, decks, docks, ramps, and pavement; to harden and dustproof new cured bare concrete; or to renovate aged surfaces.

Proportionate to coverage rate, Sonosil® will produce a light to moderately heavy-duty surface. It will also harden and improve the finish of architectural concrete after form stripping. Sonosil® is ready to use and does not require thinning.

A new superimposed hard mineral coating is formed when the inorganic silicates in Sonosil® react with the free lime and calcium carbonate in concrete, filling and sealing surface pores and capillaries. This reaction produces a finish harden than the untreated surface. Sonosil® is availabe with fugitive red dye to precisely check application. Protect Sonosil® from freezing. Compatible with most resilient floor-covering adhesives.

Compliances:

  • ASTM C 309-81, Type I, Class A (Type ID with fugitive dye), when applied at 50 sq ft per gallon
  • USDA approved for use in meat and poultry areas.

  •     SealhardTM

    L&M SealHardTM is a concrete sealer, densifier and chemical hardener. SealHardTMis a proprietary, colorless solution that penetrates concrete surfaces to seal densify, harden, dustproof and waterproof. It is VOC-compliant, environmentally safe, odorless and easy to apply. SealHardTM-treated floors are especially effective in protecting concrete floors subjected to heavy vehicle and foot traffic.

    Through a chemical-ion exchange process, SealHardTM develops internal bonds which densify the concrete substrate into a hardened, chemically-cured, homogeneous, concrete mass that resists abrasion, and reduces oil and water penetration. This chemical-ion exchange process begins after treatment and continues through the initial six months following application. SealHardTM creates an interpore molecular filter that protects concrete from carbonation and, at the same time, allows surfaces to breathe, permitting moisture vapor to ransmit naturally into the air. SealHardTM will not yellow, discolor, chip, peel or show unsightly wear patterns with use.

    SealHardTM is not a curing compound. Fresh, green concrete contains excess moisture that will inhibit the penetration of SealHardTM into the concrete surface and its ultimate effectiveness. Therefore, under normal conditions, L&M recommends using SealHardTM on concrete that is three or more days old.

    This product is licensed applicator applied only. Please call AS&G for a list of applicators.
