Solvent-based, aliphatic polyurethane top coat
The MARISEAL 400 is a pigmented, color- and UV-stable, highly permanent elastic, cold applied and cold curing, one component aliphatic polyurethane coating, used as a top-coat for protection over exposed, polyurethane waterproofing coatings.
Cures by reaction with ground and air moisture over a unique moisture triggered chemical reaction.
Protects very efficiently, especially if a dark final color is desired.
Used over the MARISEAL 250 and 260 on surfaces, with domestic pedestrian traffic (e.g. Roofs, Terraces, Residential Walkways) that require a glossy, color-stable and non-chalking finish.
120-250 gr/m2 in one or two layers.
This coverage is based on practical application by roller onto a smooth surface in optimum conditions. Factors like surface porosity, temperature, humidity, application method and finish required can alter consumption.
The MARISEAL 400 is supplied in white, light grey and red. Other RAL colors may be supplied on demand.

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.
WARNING: Do not wash surface with water!
See relevant MARIS POLYMERS product Technical Data Sheet
Stir MARISEAL 400 well before using.
Apply the MARISEAL 400 by roller or airless spray in one or two layers.
Allow 3-6 hours (not more than 36 hours) to cure, between the two layers.
For best results, the temperature during application and cure should be between 5C and 35C. Low temperatures retard cure while high temperature speed up curing. High humidity may affect the final finish.
WARNING: The MARISEAL400 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. 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.
MARISEAL 400 is supplied in 20 kg, 10 kg and 5 kg metal pails. Pails should be stored in dry and cool rooms for up to9months.Protect the material against moisture and direct sunlight. Storage temperature: 5-30C. Products should remain in their original, unopened containers, bearing the manufacturers name, product designation, batch number and application precaution labels.
MARISEAL 400 contains isocyanates. See information supplied by the manufacturer. Please study the Safety Datasheet. PROFESSIONAL USE ONLY
