MARITRANS MD

TECHNICAL DATA SHEET
Transparent, liquid-applied polyurethane waterproofing membrane

Product Description 

MARITRANS® MD 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. It waterproofs damaged glass surfaces and protects of glass fragments in case of breaking.
MARITRANS® MD is a low viscosity product ideal for use as a transparent top-coat over the MARISEAL® SYSTEM in
decorative waterproofing applications.
The MARITRANS® MD is used also as a transparent binder
resin for sandcarpet floor coating applications, especially in exterior applications where flexibility and UV stability is required.
MARITRANS® MD 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.

  • 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.

Colour

The MARITRANS® MD coating is supplied transparent

Consumption

0,3 – 1 kg/m2 in one to three layers, depending on application.
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.

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 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® MD coating.
WARNING: Do not apply the MARITRANS® MD on ceramic surfaces with ascending nitric salts in the joints, without suitable pre-treatment. Do not apply the MARITRANS® MD on surfaces treated in the past with active silane, siloxane, silicon or other water-repellents, 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 / 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® MD TILE-PRIMER is applied on the entire surface to primed and make sure that you do not leave any untreated spots.
Transparent waterproofing membrane. Pour the MARITRANS® MD coating onto the primed surface and lay it out by roller or by suitable teeth trowel, until all surface is covered at a consumption per layer of 0,3-0,5kg/m2.
After 12 hours – but not later than 18 hours –apply a second layer of the MARITRANS® MD coating, by using roller or brush.
For better waterproofing and wear resistance results, apply a third layer of the MARITRANS® MD coating.
ATTENTION: Do not apply the MARITRANS® MD over 1mm thickness (dry film) per layer. For best results, the temperature during
application and cure should be between 5o C and 35O C. Low temperatures retard cure while high temperature speed up curing. High
humidity may affect the final finish.
Finishing
If a satin matte surface is desired, apply one layer of the MARITRANS® FINISH.
Application as Transparent Top Coat in Decorative Waterproofing Applications
Surface Preparation
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%. Any loose pieces and dust need to be removed. Do not wash surface with water!
Transparent Top-Coating
Apply the MARITRANS® MD coating onto the finished, decorative designed MARISEAL® SYSTEM surface by roller at a
consumption of 0,2-0,3 kg/m2. In colored sand finished decorative applications a second coat after 6-18 hours is recommended.
WARNING: The MARITRANS® MD 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%. 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® MD 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 5o C and 35O
C. Low temperatures retard cure while high temperature speed up curing. High humidity may affect the final finish.
