MARITRANS® TECHNICAL DATA SHEET
Date: 01.06.2011 – Version 10
Transparent, liquid-applied polyurethane waterproofing membrane
Product description Advantages
The MARITRANS® is a transparent, hard-elastic, one
component, aliphatic polyurethane, high-solids coating, used
for long-lasting waterproofing. This high-technology coating is
UV-stable, non-yellowing, weather stable, alkali and chemical
resistant and even after aging it remains transparent and
elastic.
The MARITRANS® protects and waterproofs mineral surfaces
against water penetration, frost, smog and acid rain. Aged and
oxidized plastic surfaces look more transparent after coating
with MARITRANS®. It waterproofs damaged glass surfaces and
protects of glass fragments in case of breaking.
The MARITRANS® is used also as a transparent binder resin
for sandcarpet floor coating applications, especially in exterior
applications where flexibility and UV stability is required.
The MARITRANS® is using a unique curing system (moisture
triggered), and unlike other similar systems it does not react
with moisture (moisture-cured) and does not form bubbles.
• Simple application (roller or airless spray).
• When applied forms seamless transparent membrane.
• UV stable
• Resistant to water and frost.
• Crack-bridging
• Provides water vapor permeability, so the surface can breathe.
• Provides excellent thermal resistance, it never turns soft.
• Provides excellent weather resistance.
• Maintains its mechanical properties over a temperature span of
-40oC to +90oC.
• Provides excellent adhesion to ceramic tiles and glazed surface
• The waterproofed surface can be used for domestic 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.
• Used as a binder resin for sandcarpet applications, provides
high elasticity and flexibility, making it ideal for applications on
balconies and terraces.
• Over 10 years of positive feedback worldwide.
Uses Consumption
0,8 - 1,2 kg/m2 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 and application method can alter consumption.

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%. New concrete structures need to dry for at least 28 days. Old coatings, dirt, fats,
oils, organic substances and dust need to be removed. Activate (prime) and degrease glass and glazed surfaces with the
MARISEAL® TILE-PRIMER. Possible surface irregularities need to be smoothened. Any loose pieces and dust need to be thoroughly
removed. Do not wash surface with water!
ATTENTION: Surfaces with trapped moisture (e.g. trapped moisture under balconies tiles) must be left to dry completely (max. 5%
moisture), before the application of the MARITRANS® coating.
WARNING: Do not apply the MARITRANS® on ceramic surfaces with ascending nitric salts in the joints, without suitable pretreatment.
Do not apply the MARITRANS® on surfaces treated in the past with active silane, siloxane, silicon or other waterrepellents,
because of expected poor adhesion. We recommend an adhesion test, if circumstances and surface history are not clear.
On marble and granite please perform an adhesion test, to ensure that adhesion is proper.
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, hairline cracks, expansion joints and control joints of dust, residue or other contamination. Prime locally with
the MARISEAL® 710 Primer and allow 2-3 hours to dry. Fill all prepared cracks and joints with MARIFLEX® PU 30 sealant. Allow to
cure.
Priming (Activation of surface)
Prime (activate) non-absorbent glazed surfaces, like glazed ceramic tiles, glass and glass bricks with MARITRANS® TILE-PRIMER.
Apply the MARITRANS® TILE-PRIMER by soaking a clean and dry cloth, and wipe the entire surface off. By this application
procedure, you ensure that besides the chemical activation (priming) of the surface, the surface is getting also very effectively
degreased. Change cloths often. Make sure that enough quantity of MARITRANS® TILE-PRIMER is applied on the entire surface to
primed and make sure that you do not leave any untreated spots.
ATTENTION: If applied on transparent plastics (polycarbonate, polyacrylate, etc) do not use the MARITRANS® TILE-PRIMER.
Transparent waterproofing membrane
Pour the MARITRANS® coating onto the primed surface and lay it out by roller or by suitable teeth trowel, until all surface is covered.
After 12 hours - but not later than 18 hours –apply a second layer of the MARITRANS® coating, by using roller or brush.
For better waterproofing and wear resistance results, apply a third layer of the MARITRANS® coating.
ATTENTION: Do not apply the MARITRANS® over 1mm 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 a satin matt surface is desired, apply one layer of the MARITRANS® FINISH.
WARNING: The MARITRANS® coating 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.
Application as a Binder Resin for Sandcarpet Coating.
Surface Preparation
Careful surface preparation is essential for optimum finish and durability.
If applied on MARISEAL 250 make sure that the surface is clean, dry and sound, free of any contamination, which may harmfully
affect the adhesion of the sandcarpet coating. Maximum moisture content should not exceed 5%. Possible surface irregularities need
to be smoothened. Any loose pieces and dust need to be thoroughly removed. Do not wash surface with water!
If applied onto concrete, make sure that the surface is clean, dry and sound, free of any contamination, which may harmfully affect
the adhesion of the membrane. Maximum moisture content should not exceed 5%. New concrete structures need to dry for at least
28 days. Old coatings, dirt, fats, oils, organic substances and dust need to be removed. Possible surface irregularities need to be
smoothened. Any loose pieces and dust need to be thoroughly removed. Do not wash surface with water!
Priming
Prime concrete surfaces with MARISEAL 750 primer and broadcast silica sand while still wet.
Sandcarpet Coating
Mix the MARITRANS® with colored Silica Sand (cornsize 0,7-1,2mm or 2,0-3,5mm) in a mixing ratio of 1:10 (resin: sand) by
weight, with a low speed mechanical mixer, until the mixture becomes fully homogenous.
Pour the mixture onto the prepared surface and apply by flat trowel.
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.
Packaging
MARITRANS® is supplied in 20 kg, 10 kg, 5 kg and 1kg pails. Pails should be stored in dry and cool rooms for up to 9 months. Protect
the material against moisture and direct sunlight. Storage temperature: 50-300C. Products should remain in their original, unopened
containers, bearing the manufacturers name, product designation, batch number and application precaution labels.
