    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.

    Liquid-applied, 100% polyurethane waterproofing membrane
    Product description
    The MARISEAL® 250 AQUA is a liquid-applied, highly permanent elastic, cold applied and cold curing, water based, one component, 100% polyurethane-based membrane used for long-lasting waterproofing. The MARISEAL® 250 AQUA consists of flexible, water-based polyurethane resins (dispersion), without the addition of inferior acryl resins and other admixtures. When the MARISEAL®250 AQUA is applied, it forms a hydrophobic, 100% waterproofing, seamless, polyurethane membrane without joints or leak possibilities, that protect old and new structures efficient and on a long term basis. The MARISEAL® 250 AQUA is based on the innovative PUD-Technology™ of MARIS POLYMERS SA.

    Advantages
    Simple application (roller or airless spray).
    Water Based.
    When applied forms seamless membrane without joints.
    Resistant to water.
    Resistant to frost.
    Provides high levels of crack bridging.
    Maintains its mechanical properties over a temperature span of
    -40oC to +90oC. Provides water vapor permeability.
    Full surface adherence without any additional anchoring.
    The waterproofed surface can be walked on.
    Even if the membrane gets damaged, it can be easily repaired locally within minutes.
    Low VOC content < 100g/l
    Low cost
    The MARISEAL 250 AQUA was awarded with the SINGAPORE
    GREEN LABEL certification.

    Consumption
    1,4 – 2 kg/m2 applied in two or three layers. This coverage is based on application by roller onto a smooth surface in optimum conditions. Factors like surface porosity, temperature application method can alter consumption.

    Colors
    The MARISEAL® 250 AQUA is supplied in white, grey, brownred.

    Uses
    • Waterproofing of Rooftops
    • Waterproofing of Balconies and Terraces
    • Waterproofing of Wet Areas (under-tile) in
    Bathrooms, Balconies, Kitchens, etc
    • Protection of Polyurethane Foam Insulation
    • Waterproofing and protection of Concrete
    constructions like Bridge-decks, Tunnels, etc.
    PUD Technology™: The Green revolution in Polyurethane
    The MARISEAL® 250 AQUA is based on the innovative PUD Technology™ of MARIS POLYMERS SA,
    which enables, long-chain polyurethane macromolecules to be incorparated in a water medium, forming
    stable dispersions.
    The PUD Technology™ based products, have the advantage that they offer the high level properties of
    solvent based products, in an ecological, consumer and evironmentally friendly, water-based, low VOC,
    no ADR transport product.
    The PUD Technology™ is the entry to the Green revolution in Polyurethane based products.

    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 8%. 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.

    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®
    AQUA PRIMER and allow 2-3 hours to dry. Fill all prepared cracks with MARIFLEX® PU 30 sealant. Then apply a layer of
    MARISEAL® 250 AQUA, 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®250 AQUA, until it is fully covered. Allow 18 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 the movement 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®250 AQUA, 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® 250 AQUA. 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 18 hours to cure.

    Priming
    Prime highly absorbent and brittle surfaces like concrete, cement screed, mortar, plaster, wood and non-absorbent surfaces like metal and ceramic tiles with MARISEAL® AQUA PRIMER. Allow the primer to cure according its technical instruction. Waterproofing membrane Stir well before using. Poor the MARISEAL®250 AQUA onto the prepared and 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. Reinforce always with the MARISEAL®FABRIC at problem areas, like wall-floor connections, pipes, chimneys, waterspouts (siphon), lightdomes, etc. In order to do that, apply on the still wet MARISEAL® 250 AQUA a correct cut piece of MARISEAL® FABRIC, press it to soak, and saturate again with enough MARISEAL® 250 AQUA. For detailed application instructions with the MARISEAL® FABRIC, contact our R+D department. After 18-36 hours apply another layer of the MARISEAL®250 AQUA. For better waterproofing results apply a third layer of the MARISEAL® 250 AQUA.
    ATTENTION: Do not apply the MARISEAL®250 AQUA over 0.5 mm thickness (dry film) per layer.
    ATTENTION: Do not apply the MARISEAL 250 AQUA in negative (degC) temperatures or when rain or frost is imminent in the next 48 hours. 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 (fog or dew conditions) retard cure and affect the curing times.

    Finishing
    If a color stable, chalking-free and heavy duty, more abrasion resistant surface is desired, apply one or two layers of the MARISEAL® 400 AQUA Top-Coat over the MARISEAL® 250 AQUA. The application of the MARISEAL®400 AQUA Top-Coat, is especially required, if a dark final color, is desired. (e.g. red, grey, green)
