    Roof Waterpoofing Coating
    Roof waterproofing coating is very important. Roofs are not just visual features; they fulfill the crucial role of protection. Be it a classic flat roof or a dome roof, every roof structure has a unique character.Being the highest point in a building, they take a battering from the elements and leaking is common after a few years.MARIS POLYMERS offers liquid-applied Polyurethane waterproofing systems for roof coating with long-term protection for simple, detailed or complicated roof structures.The MARISEAL SYSTEM® is the technologically advanced,premium liquid polyurethane waterproofing system that offers easy application, full certifications, and most importantly guaranteed long lasting results.It can be used as a new flat roof coating, but also for repair or renewal. The MARISEAL SYSTEM® consists of different products, dependant on the roofs characteristics.

    Product description
    The MARISEAL® 260 is a liquid-applied, highly permanent elastic, cold applied and cold curing, one component polyurethane membrane used for long-lasting waterproofing. Solvent based.The MARISEAL® 260 is based on pure elastomeric hydrophobic polyurethane resins, which result in excellent mechanical, chemical, thermal and natural element resistance properties.Requires covering with suitable top-coat. Cures by reaction with ground and air moisture.

    Advantages
    Simple application (roller or airless spray).
    • When applied forms seamless membrane without joints.
    • Resistant to water and
    • Resistant to frost.
    • Crack-bridging.
    • Provides water vapor permeability, so the surface can breathe.
    • Provides excellent thermal resistance, it never turns soft.
    • Provides excellent weather resistance.
    • Waterproofs old bitumen-, asphalt felts by covering them,
    without the need to remove them prior to application.
    •Maintains its mechanical properties over a temperature span of -30oC to + 90oC
    Provides excellent adhesion to almost any type of surface.
    •The waterproofed surface can be used for domestic and public
    pedestrian traffic.
    • Resistant to detergents, oils, seawater and domestic chemicals.
    • Even if the membrane gets mechanically damaged, it can be
    easily repaired locally within minutes.
    • Does not need the use of open flames (torch) during application.
    Over 15 years of positive feedback worldwide.

    Consumption
    This coverage is based on application by roller onto a smooth
    surface in optimum conditions. Factors like surface porosity,
    temperature and application method can alter consumption.

    Colors
    The MARISEAL 260 is supplied in off-white and light grey.
    Other colors may be supplied on demand.

    Surface Preparation
    Careful surface preparation is essential for optimum finish and durability.
    The surface needs to be clean, dry and sound, free of any contamination, which may harmfully affect the adhesion of the membrane. Maximum moisture content should not exceed 5%. Substrate compressive strength should be at least 25MPa, cohesive bond strength at least 1.5MPa. New concrete structures need to dry for at least 28 days. Old, loose coatings, dirt, fats, oils, organic substances and dust need to be removed by a grinding machine. Possible surface irregularities need to be smoothened. Any loose surface pieces and grinding dust need to be thoroughly removed. Do not wash surface with water!
    Repair of cracks and joints:
    The careful sealing of existing cracks and joints before the application is extremely important for long lasting waterproofing results.
    • Clean concrete cracks and hairline cracks, of dust, residue or other contamination. Prime locally with the MARISEAL®
    710 Primer and allow 2-3 hours to dry. Fill all prepared cracks with MARIFLEX®PU 30 sealant. Then apply a layer of MARISEAL®260, 200mm wide centered over all cracks and while wet, cover with a correct cut stripe of the MARISEAL®
    Fabric. Press it to soak. Then saturate the MARISEAL®Fabric with enough MARISEAL®260, until it is fully covered. Allow 12 hours to cure.
    • Clean concrete expansion joints and control joints of dust, residue or other contamination. Widen and deepen joints (cut open) if necessary. The prepared movement joint should have a depth of 10-15 mm. The width:depth ratio of themovement joint should be at a rate of approx. 2:1.
    Apply some MARIFLEX®PU 30 Joint-Sealant on the bottom of the joint only. Then with a brush, apply a stripe layer of MARISEAL®260, 200mm wide centered over and inside the joint. Place the MARISEAL®Fabric over the wet coating and with a suitable tool, press it deep inside the joint, until it is soaked and the joint is fully covered from the inside. Then fully saturate the fabric with enough MARISEAL®260. Then place a polyethylene cord of the correct dimensions inside the joint and press it deep inside onto the saturated fabric. Fill the remaining free space of the joint with MARIFLEX®
    PU 30 sealant. Do not cover. Allow 12-18 hours to cure.

    Priming
    Prime very absorbent surfaces like concrete, cement screed or wood with MARISEAL®
    710 or with MARISEAL®
    AQUA PRIMER.
    Prime surfaces like bitumen-, asphaltfelts with MARISEAL®
    730 or with MARISEAL®
    AQUA PRIMER. Prime non-absorbent surfaces
    like metal, ceramic tiles and old coatings with MARISEAL®
    AQUA PRIMER. Allow the primer to cure according its technical
    instruction.
    Waterproofing membrane
    Stir well before using. Poor the MARISEAL®
    260 onto the primed surface and lay it out by roller or brush, until all surface is covered.
    You can use airless spray allowing a considerable saving of manpower.
    After 12-18 hours (not later than 48 hours) apply another layer of the MARISEAL®
    260. For demanding applications, apply a third layer of the MARISEAL®
    260. Reinforce always with the MARISEAL®
    Fabric at problem areas, like wall-floor connections, 90o
    angles, chimneys, pipes,
    waterspouts (siphon), etc. In order to do that, apply on the still wet MARISEAL®
    260 a correct cut piece of MARISEAL®
    Fabric, press it to soak, and saturate again with enough MARISEAL®260. For detailed application instructions with the MARISEAL®Fabric, contact our R+D department. RECOMMENDATION: At concealed surfaces or on highly cracked surfaces, we recommend reinforcement of the entire surface, with the MARISEAL®Fabric. Use 5-10cm stripe overlapping.
    ATTENTION: Do not apply the MARISEAL®260 over 0.6 mm thickness (dry film) per layer. For best results, the temperature during application and cure should be between 5oC and 35OC. Low temperatures retard cure while high temperature speed up curing. High humidity may affect the final finish.
    Finishing
    If the MARISEAL 260 is applied on exposed surfaces, apply one or two layers of the color stable and totally UV stable
    MARISEAL®400 Top-Coat over the MARISEAL®260. If a heavy duty, abrasion resistant surface is desired (e.g. Public Pedestrian Deck, etc), apply two layers of the MARISEAL®
    420 Top-Coat. For the several Top-Coats application procedures, please consult their technical instructions.
    WARNING: The MARISEAL®system is slippery when wet. In order to avoid slipperiness during wet days, sprinkle suitable
    aggregates onto the still wet coating to create an anti-slip surface. Please contact our R+D Dept. for more details.
