Waterproof Coating

    ThoroSeal® Foundation Coating


ThoroSeal Foundation Coating® is a cement-based, heavy-duty waterproof coating, designed specifically to waterproof the exterior surface of concrete and masonry foundations below grade. (ThoroSeal® Foundation Coating is not intended as a decorative finish coat.) Normally applied with an ordinary coarse-fibered brush, ThoroSeal® Foundation Coating becomes an integral part of the concrete or masonry surface, not merely a film covering.

Dampproof Coating

    Sealmastic™ Emulsion


SealmasticTM Emulsion-type dampproofing is a breather-type that permits moisture vapor to escape through the film, while remaining resistant to water penetration. This prevents blistering of applied films. The product can be applied to green concrete (not totally dry).

Type II - Brush-On/ Spray-Grade is an asphalt-based, clay emulsion with fibers specifically formulated to offer a tight film that combines both excellent strength and resistance to water.

USE: SealmasticTM Emulsion coatings are ideal for reducing dampness and moisture infiltration through foundation walls, parapets, fire walls, tanks, culverts, cisterns and bridge abutments. They are also applicable for stone-backing, above-grade cavity wall applications and below-grade masonry wall dampproofing. The SealmasticTM product line also helps to minimize internal structural damage from mildew and mold.

    Blok-Guard® &
    Graffiti Control (Sure Klean)


Blok-Guard® and Graffiti Control is a clear, solvent-based silicone elastomer formulated to weatherproof concrete block and other porous masonry materials. It protects masonry surfaces from repeated graffiti attacks without altering the natural appearance. It penetrates and fills pores to prevent water penetration through exterior walls exposed to normal weathering. Graffiti removal is fast and easy using Defacer Eraser® Graffiti Wipe. Blok-Guard® and Graffiti Control is easy to apply with low-pressure spray, brush or roller.

ADVANTAGES:

  • Treated surfaces resist penetration of most types of graffiti.
  • Simplifies graffiti removal.
  • Effective protection for hard-to-seal surfaces.
  • Controls rainwater penetration through exterior block walls.
  • Helps control efflorescence, mildew and other moisture-related stains.
  • Treated surfaces exhibit excellent surface beading and withstand extreme temperatures.
  • Treated surfaces 'breathe'.
  • Excellent UV stability.

        Paver Enhancer (Sure Klean)


    Paver Enhancer is a solvent-based blend of high-quality siloxanes modified to provide excellent water repellency and color enhancement to interlocking concrete, fired clay, porous tile and many types of natural stone surfaces. Paver Enhancer penetrates and reacts with the surface to form a chemical bond, providing long-term durability, alkali resistance and superior breathability.

    ADVANTAGES:

    • Provides excellent color enhancement.
    • Controls rainwater penetration through hard-to-seal surfaces.
    • Helps control efflorescence, and moisture- and traffic-related staining.
    • Simplifies cleaning.
    • Low odor.
    • Treated surfaces “breathe” – does not trap moisture.Limitations

        Siloxane WB Concentrate


    Siloxane WB Concentrate (Sure Klean) is a self-emulsifying water repellent concentrate designed for dilution with fresh water at the jobsite. This solvent-free blend of silanes and oligomeric alkoxysiloxanes mixes easily with water to produce a penetrating water repellent ideal for application to dense or porous masonry surfaces. Siloxane WB can also be used as a primer to even out porosity and improve adhesion of BMC® Breathable Masonry Coatings.

    An effective alternative to conventional solvent-based silanes or siloxanes, Siloxane WB penetrates and chemically bonds deep within the masonry substrate to provide long-lasting protection against water-related staining or deterioration. Will not darken, produce a surface film or impair the natural breathing characteristics of treated surfaces.

    Hardeners/ Sealers

        SealHard™


    L&M SealHard™ 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.
