Roof Waterproofing 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.
Polyurethane Top-Coat, UV-stable, Abrasion resistant, Water-based
Product description Advantages
The MARISEAL® 400 AQUA is a water-based, pigmented, wear resistant, semi-rigid, color- and UV-stable, weather-stable, one component, aliphatic, 100% polyurethane coating used as a top-coat for protection over MARISEAL® waterproofing membranes, subject to wear and weathering conditions. The MARISEAL® 400 AQUA consists of flexible, water-based polyurethane resins (dispersion), without theaddition of inferior acryl resins and other admixtures. When the MARISEAL® 400 AQUA is applied, it forms a hydrophobic, 100% waterproofing, seamless, polyurethane coating, that protects the waterproofing basecoat efficient and on a long term basis. The MARISEAL® 400 AQUA is based on the innovative PUD-Technology™ of MARIS POLYMERS SA.
• Simple application (roller or airless spray).
• Water Based
• Resistant to abrasion and wear conditions.
• Color stable.
• Gives an easy-to-clean surface.
• Does not show the chalking effect of aromatic polyurethane
waterproofing coatings.
• Resistant to water.
• Maintains its mechanical properties over a temperature span
of -30oC to +80oC.
• Low VOC content <100 gr/l
• Resistant to frost.
• The MARISEAL 400 AQUA was awarded with the SINGAPORE
GREEN LABEL certification.
Uses Consumption
0,2 – 0,4 kg/m2 applied in one or two layers. 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
Used over the MARISEAL® waterproofing membranes for:
• Waterproofing of Rooftops
• Waterproofing of Balconies/Terraces
• Waterproofing of pedestrian areas (Decks)
• Protection of Polyurethane Foam Insulation
• Waterproofing of most surfaces exposed to wear and
weathering conditions.
• Used over the MARISEAL® 250 AQUA on surfaces, with domestic pedestrian traffic (e.g. Roofs, Terraces,
Residential Walkways) that require a glossy, color-stable and non-chalking finish. Also used by its own, for the fiber encapsulation of old exposed asbestos surfaces.
The MARISEAL® 400 AQUA is supplied in white, light grey and brownred. Other RAL colors supplied on request. PUD Technology™: The Green revolution in Polyurethane The MARISEAL® 400 AQUA is based on the innovative PUD Technology™ of MARIS POLYMERS, 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.
MARISEAL®
400 AQUA pails should be stored in dry and cool rooms for up to 18 months. Protect the material against moisture and
direct sunlight. Storage temperature: 5o-30oC. Products should remain in their original, unopened containers, bearing the
manufacturers name, product designation, batch number and application precaution labels. PROTECT FROM FROST.
Application
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.
Top-Coat
Stir well before using. Apply the MARISEAL®400 AQUA over the MARISEAL® waterproofing membrane by roller or airless spray in one or two layers, depending on the future wear conditions expected. Allow 3-6 hours (not more than 8 hours) to cure between two layers.
WARNING: If on the surface where the MARISEAL® system is applied, there are areas with ponding water, they should be cleaned on regular basis to avoid biological and microbial attack.
ATTENTION: Do not apply the MARISEAL®
400 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 5o
C 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.
WARNING:
The MARISEAL® 400 AQUA and/or 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 Department for more details.
